Can AGM Batteries Suffer Thermal Runaway like Lithium Ion Batteries?

 

 

The Question –

Can AGM Batteries suffer thermal runaway like Lithium Ion Batteries: Are they safe?

 

The Answer –

Does everyone know that when our RG series batteries are subject to the destructive overcharge test that they do NOT thermally runaway?

They get HOT about 260F, the electrolyte boils, the water turns to steam and the excessive internal pressure opens the vent valves releasing the steam (H20) NO ACID is expelled.  This continues for about 10 minutes and as soon as the battery runs out of water the charge current stops and the battery starts to cool down to ambient.

Annunciator light functionality - NiCads

 

 

The Question –

Working on King Air 300 FA-85 with RG380E/44 installed. Have minor issue with Batt charge annunciator and can not locate wiring changes made when ACFT went from NiCad to Lead acid. If you could assist or point me in direction who could please do. Thanks for your time.

 

The Answer –

The CONCORDE King Air STC has the option of taking one of the battery charging cable shunt sensing lead off if the charge light is a nuisance to the operator.

But, it is a great system and the light comes on as long as at least 7 to 10 amps are charging the battery. Normally, with a healthy battery the light goes out before takeoff. IF THE CHARGING SYSTEM IS SET PER THE BEECH MM AT 28 TO 28.5 DCV.

Most of the NiCad's are 20 cell and the charging system is set upwards of 29DCV which is too high for our 24V batteries and the charge light stays on for a long time .

The reason we like to leave the charge light system functional is that it is a CURRENT SENSING SYSTEM And if the light comes on during flight, the pilot merely disconnects the battery that is just showing signs of an internal short , but fully charged and if later the generating system fails, the charged battery can be put back on line to support the load requirements.

Arcing Conditions

 

 

The Question –

We have an RG380E/44 battery, S/N: 40450578 that has slight arcing on the negative battery terminal from a loose connection at the connector. We have replaced the aircraft connector but I cannot find any information in the CMM, (5-0171, Rev P), regarding how to repair this condition. Can you advise on how to repair so that I have manufacturers data/recommendations for repair and return to service please?

 

The Answer –

The battery terminal pins are .375 or 3/8” in diameter. Make sure you remove any copper deposits from the plug socket terminals so the pins will have maximum contact with the airframe plug sockets.

Make a go-no-go gage from a 3/8 drill rod or bolt that you can use to check ALL YOUR AIRFRAME PLUG SOCKETS. There needs to be enough tension on each socket, so that the 3/8” diameter gage will not slip out when the airframe plug is inverted.

The battery terminal pins are silver plated, protect them from corrosion using ACF-50 in the plug sockets.

Battery Safety – How Does This Affect You

 

 

All safety precautions are covered in our component maintenance manuals, more commonly known as the CMMs. There's a CMM for RG series main aircraft batteries and a separate CMM for RG series emergency aircraft batteries. The safety aspects are the same in both CMMs. A list of the safety hazards is shown on the screen. These include, A, low capacity hazard, B, electrical burn hazard, C, danger of exploding batteries, D, chemical burn hazard, and E, damage to equipment.

 

Regarding the low capacity hazard, the FAA generally requires aircraft batteries to provide backup power in the event of a generator system failure. Never use a battery that has less than 80% of its rated capacity and never jumpstart an aircraft that has a dead or a discharged battery. Think aircraft safety, not just battery safety.

 

Regarding the electrical burn hazard, batteries can generate very high levels of current if the terminals are shorted together. The object that causes the short circuit will get very hot due to the high current and will cause a burn hazard. To prevent electrical burns, take off any metallic jewelry such as bracelets and necklaces that could potentially cause a short circuit across the battery terminals. Also, do not allow your belt buckle to contact the battery connector. Getting burned by a shorted belt buckle is more common than you might think. Obviously, it's not a good idea to place tools or other metal objects across battery terminals. For example, you may be tempted to use a steel ruler or a caliper to measure the distance between battery terminals, as some of us have found out the hard way, severe damage to you and the tool can happen pretty rapidly. As an extra precaution, it's a good idea to install battery terminal protectors when the battery is not connected to test equipment.

 

Regarding the danger of exploding batteries, lead acid batteries can cause explosions because they produce hydrogen and oxygen while on charge. However, there should not be any danger of explosion if you take the following precautions. First, make sure the work area is well ventilated so any hydrogen given off by the battery gets adequately diluted. Second, don't smoke, use an open flame or cause sparking near a battery. Remember that there could be local areas of hydrogen build up in the vicinity of the battery even if the work area is well ventilated. Third, wear proper eye protection when servicing batteries such as safety goggles or a face shield. And finally, do not charge a battery at constant current when it is installed in the aircraft. Constant current charging should only be done in a well ventilated area because a significant amount of hydrogen gas may be released from the battery. Battery compartments on most aircraft do not have adequate ventilation to handle the extra volume of hydrogen that is released so this would cause a potential explosion hazard on the aircraft.

 

Regarding the chemical burn hazard, lead acid batteries contain sulfuric acid in the electrolyte which can cause severe chemical burns. To avoid chemical burns, the following precautions should be taken. Never remove or damage the vent valves, avoid contact with the battery's electrolyte if the battery gets cracked or broken open. Don't touch your eyes after touching the battery, wash your hands first. If electrolyte does get into your eyes or on your skin, flush thoroughly with clean, cool water for several minutes and get medical attention as soon as possible. And finally, the last point is regarding equipment damage. To prevent equipment damage, ensure that the aircraft battery switch, external power source or the charger analyzer is in the off position before connecting or disconnecting the battery. If the circuit is not off when making or breaking connections, the battery terminals may arc and cause damage to the battery, equipment cables or both.

 

If these instructions are followed, then all potential safety hazards will be fully mitigated. Also, as a reminder, the CMMs provide full coverage of the safety hazards and precautions.

 

To complete your training, please take time to read the safety summary in the CMM. Also, take time to read the SDS, safety data sheet, for additional information. The CMM and SDS are posted on the Concorde Battery website for easy access. Finally, if you have any questions on this subject, contact Concorde's customer service department. Thank you everyone. Be safe.

Battery Storage and Installation Preparation – Just the Facts Please!

 

Why it is important to properly store an aircraft battery and how to accomplish this?

Proper storage of an aircraft battery is important because it directly impacts the battery's performance capability as well as its total service life. To understand this, let me describe what happens to the battery during storage. When a battery is in storage, it gradually loses charge even though there is no load on the battery. This process is known as self-discharge and is illustrated in the chart shown on the screen. The capacity retention ratio, or state of charge, decays with time and the rate of decay is strongly affected by the storage temperature. The higher the temperature, the faster the battery loses its charge. As a battery self-discharges, the plates become sulfated and the internal resistance of the battery increases. If the sulfate level in the plates gets too high, the battery will take a lot longer to charge and will not last as long.


To actually see sulfation, take a look at the high magnification photos of sulfated plates and un-sulfated plates shown on the screen. The photo on the left shows the sulfated plate with large sulfate crystals. This is what causes the high resistance in the battery. To prevent the sulfate levels from getting too high, the battery needs to be boost charged to get it back to 100% state of charge. The photo on the right shows the plate after charging, which erases the sulfate crystals. Fortunately, a simple check of the battery's open-circuit voltage with a digital multimeter can be used to determine the condition of the battery.


The table shown on the screen summarizes the instructions from the CMM. A fully charged battery will have an OCV of about 13 volts for a 12-volt battery and about 26 volts for a 24-volt battery. While in storage, the OCV should not be allowed to drop below 12.5 volts for a 12-volt battery or below 25.0 volts for a 24-volt battery. The OCV should be checked every two to four months depending on the storage temperature. If the OCV is getting close to these values, the batteries should be boost charged with a constant potential charger.


Note that if the OCV is allowed to drop below the minimum, a capacity test will be necessary before it can be installed in an aircraft. This is to make sure that the sulfated plates can be restored to a good condition, so obviously, it is best to not let the OCV drop below the minimum. The worst thing that you can do is to put the battery on a shelf indefinitely and ignore the battery's state of charge. Eventually, the battery can become so sulfated that it will not recover and will have to be scrapped.


Another thing that is covered in the CMM is the storage temperature. Ideally, the storage temperature should be below 68 degrees F or 20 degrees C. Referring back to the capacity retention chart, you can see why cooler temperatures are preferred. At 20 degrees C, it takes about 15 months to reach 50% state of charge. At 30 degrees C, it only takes nine months to reach 50% state of charge. And at 10 degrees C, it takes well over 18 months to reach 50% state of charge. So, the cooler it is during storage, the longer you can go before a boost charge is necessary. However, if you cannot avoid storing the battery at warmer temperatures, it just means you will have to boost charge the battery more often.

 

One of the popular myths I hear is not to store it on a concrete floor because this will cause the battery to discharge very quickly. Is this correct?

 

No, that is not correct. That myth is a carryover from early automotive batteries that sometimes had acid residue on the case, which could contact the concrete. This would cause a rapid self-discharge of the battery. Today's lead-acid batteries do not have this issue. The only factor that affects the rate at which a battery self-discharges is the ambient temperature. Cooler is always better.

 

I think the easiest way to cover this topic is by referring to the flow chart shown on the screen. First, we want to do a visual inspection to check the overall physical condition of the battery to make sure there are no obvious signs of damage. If you see any damage, don't install the battery because it may not be airworthy and it's not worth the risk. Next, measure the open-circuit voltage of the battery with a digital multimeter. As long as the voltage is equal to or greater than 25.5 volts, the battery can be installed. If the voltage is equal to or greater than 25.0 volts but less than 25.5 volts, then it will need a constant potential boost charge before installing it in the aircraft. If the voltage is less than 25.0 volts, then you will have to charge the battery at constant potential and follow that up with a capacity test.


As long as the battery passes the capacity test, it is acceptable for aircraft installation. Note, that for a 12-volt battery, all of the voltage requirements are cut in half.

The flowchart is included in Appendix B of the CMM. I also want to point out that the CMM is a governing document for servicing Concorde aircraft batteries, and this video does not take the place of the CMM. If you have any questions regarding the CMM, please contact Concorde's customer service department. Thank you, everyone. Be safe.

Voltage Regulator Overcharging

 

 

The Question –

If a voltage regulator is set to 14.1 , how does it not overcharge a 12V battery on a long trip, or when the battery is back fully charged, does the regulator continue to attempt to pump 14.1 into the battery? Would that not eventually dry out the matts?

 

The Answer –

No, first the battery is not fully charged after an engine start or worse if the airplane has been inactive. It will take about 3.5 hours to fully charge the battery, then 14.1 IS NOT OVERCHARGING IT, merely charging it normal at RT, too low at cold temperatures and too high or overcharging it at 100F or higher, look in the O/O manual for recommended charging voltages at temperature.

If the recommended charging voltage at the battery temperature is exceeded then yes, the vent valves will allow water to be consumed and the battery will dry out, but this rarely ever happens.

Amp Meter/Volt Meter Oscillation

 

 

The Question –

Battery SN 40858991 was installed 4/4/17 @ 3159.69 hrs, removed 4/16/17 @ 3162.86 hrs. Induced amp meter and Volt meter oscillation. (And panel lights) Old battery worked perfect when re installed. Why?

 

The Answer –

This is the old-style magnetic coil relay voltage regulator that is not fast enough to dampen the overvoltage charging that happens with an RG battery that has lower internal resistance than a flooded battery that has fewer plates per cell.

The older voltage regulator recognizes the battery is going OVER the CP limit and shuts the generator or alternator off, but the battery not being fully charged voltage starts to drop below the normal charging voltage , then the voltage regulator senses it, and the magnetic coil relay contacts close and the fast charge starts again until the battery goes over voltage again.

These events are rapid within seconds, but all electrics either go off and on, or lights flicker as the ammeter is fluctuating from charge to discharge and back and forth.

Two ways to fix the problem - replace the old voltage regulator or alternator control unit with a solid state, or go back to using an old fashioned flooded electrolyte battery.

Short Duty Cycles : Skip's Corner

Short Duty Cycles

 

 

The Question –

Do short duty cycles have an effect on battery longevity?

 

The Answer -

I will attempt to explain why ANY aircraft battery is NOT designed to perform satisfactorily with short durations of being recharged between the high rate of current of discharge (capacity) required to make a successful turbine engine starts.

Think of the storage battery as being like a bucket of water. With an open top that is full (charged capacity) that you can dump or spill as much as you want rapidly (loss of capacity) BUT you only have a limited volume of water capacity to refill the empty bucket because of your resupplying water filling pipe or hose, so you cannot replenish the capacity lost that you had quickly dumped for some reasonable time before the bucket is full (capacity) again.

Storage batteries are something like this, they can release high rates of power to crank a turbine engine from its static or stopped condition to the starter/generator that is also not moving and because it takes hundreds of amperes to overcome this stalled condition to get all the rotating components moving (at least ten percent of the capacity is used to motor the engine) to draw the cool air into the compressor section BEFORE the compressed air is introduced to the combustion section where fuel is ignited and the fire and super-heated air impinges on the turbine to provide enough energy to have the turbine drive the compressor so the electric starter motor than can be shut off.

Usually aircraft turbine starting batteries have enough stored energy (capacity) to make three successful starts before their capacity is drained to the point of causing a hot or aborted start

A storage battery in a poor state of charge (SOC) or health (worn out below the minimum airworthiness requirement) will and do cause hot starts the ruin the turbine engine, IF the battery DOES NOT HAVE ENOUGH CAPACITY to keep the starter motor turning the engine , driving the compressor and forcing the hot air back to drive the turbine until the turbine can drive the compressor, then the engine stalls and the hot air and flames are allowed to back-up into the aluminum compressor section causing EXPENSIVE engine overhauls or replacements

My first suggestion would be to modify your 350/355’s with the Canadian Airbus Helicopter STC to install our 28Ah P/N RG-390E in the tail boom.

Second install a spare battery, I believe Airbus Helicopters has a SB for dual batteries, If not AIRLIFT in Norway does.

Third, carry a start stick by STARTPAC .

Bulging Batteries

  

The Question –

Is a sealed battery airworthy if it is bulging?

 

The Answer –

Yes, this is normal when the internal gas pressure is higher than the outside atmospheric pressure, it’s a GOOD sign as each cell pressure relief valve is not leaking.

The cell pressure relief valves remain closed normally but do burp occasionally to relieve excess internal pressure while in service. The recombinant gas battery requires a positive internal pressure to operate normally.

The case will go concave if the aircraft makes a rapid descent from a high altitude.

ALL rechargeable batteries of any type are called “secondary” and ALL have pressure relief valves to prevent the battery case from rupturing or bursting due to high gas pressure that may be caused by overcharging with higher than recommended voltage from either internal or external power. Sometimes this happens to batteries that are shipped in a charged state that are of normal shape at the time of shipment and are subject to either higher or lower atmospheric pressure during transit.

ST04366AT allows for two RG-380E/60L (48 Ah) or two RG-38E/53L (53 Ah) AGM sealed lead acid batteries to replace the original equipment nickel-cadmium batteries resulting in 20-40% more battery capacity per aircraft without airframe modification. A temperature sensor kit, part number 5-0121, is included with the STC for each battery.

 

Concorde has a proven history of success in Citation aircraft. RG® Platinum Series® batteries perform as well or better than nickel-cadmium batteries and are maintenance free requiring no water replenishment, deep cycling or replacement parts and cells. Upgrading to Concorde batteries reduces down time and provides a more economical option through lower acquisition cost and reduced maintenance.

 

Concorde batteries are shipped fully charged and tested. They are hazmat exempt and are 100% recyclable.

 

Concorde Battery Corporation is the lead acid aircraft battery chosen by airframe manufacturers and end users alike due to the industry leading standards of excellence in safety, reliability and longevity sustained over 40 years in business. Concorde is committed to providing the highest quality lead acid battery solutions and world class customer support.

3-8-2017 - Concorde`s High Capacity RG-427 Now Available for Bell 407 and Bell 427

RG 427West Covina, CA - Concorde Battery Corporation is pleased to announce that Rotorcraft Support Inc. of Van Nuys California has received a FAA STC to install the RG-427, 34 Ah battery, in Bell 407 and Bell 427 helicopters.

 

Operators have requested a higher capacity battery for the Bell 407 as this helicopter is often used in high cyclic and short leg operations. In these types of operations, the original equipment 28 Ah battery is not getting fully recharged causing starting performance during successive engine starts to degrade and shorten battery life. The decrease in power also causes unnecessary wear on engine components.

 

Air Ambulance and Oil & Gas fleets conduct some of the highest cycle operations. These operators will realize an increase in starting power and improved performance after upgrading to the RG-427, 34 Ah, 24 volt battery that is packed with over 20% more power than the 28 Ah battery.

 

Rotorcraft Support Inc. has added the RG-427 to their FAA approved STC SR01456LA for the Bell 407. This STC was also upgraded to include RG-407, 27 Ah, and RG-427 installation approval on Bell 427 helicopters. This is the first FAA STC approved for Recombinant Gas (RG®) sealed lead acid batteries in the Bell 427!

 

Concorde has supplied lead acid batteries as original equipment and direct replacements for fixed wing, rotorcraft and unmanned aircraft for decades. Concorde offers over 100 unique batteries installed as original equipment by the majority of aircraft manufacturers and adopted by military aircraft operators worldwide.

 

Rotorcraft Support, Inc., has been in business since 1986, and is a full service helicopter maintenance facility located at the Van Nuys Airport in Southern California. RSI`s helicopter maintenance and helicopter repair services are beyond compare. Their reputation for safety, precision work and responsiveness has earned them respect in the helicopter community. They value that respect, and continuously strive to maintain this level of excellence in their organization.
