Depends on operational profile (how often and how long do you fly) as well as ambient and operational temperatures. If you don't fly often, then the battery should be kept on a boost charge regimen, or, on a trickle charger that adjusts the float voltage based on ambient temperaturs for one week per month. The BatteryMINDer has this capability.

Recommend the BatteryMINDer for 12V and 24V batteries.

Only 12V batteries reference CCA. They are listed on the website under the RG-25/XC and RG-35A/AXC. Aviation batteries reference Ipp (the discharge current delivvered at 0.03 seconds) and Ipr (the discharge current delivered at 15 seconds) rather than CCA..

Nothing changed. Are you flying or storing the aircraft differenctly? Are you keeping battery fully charged when not flying? Have you checked your voltage regulators to make sure they are set correctly? Is your alternator / generator functioning correctly? Do you have a parasitic load (drain) that is discharging your battery?.

Try a deep discharge recovery as defined in the CMM. Can also try the condition charge. See CMM Document No. 5-0171.

Fill out information on the battery warranty card. Contact any CBC distributor to start the warranty process. Please include all requested warranty details to expedite the process. For full warranty coverage please reveiw our warranty.

Measure the Open Circuit Voltage (OCV) of the battery. Perform a condition charge. If you see an improvement, but the voltage is still low, try another one. In all liklihood, the battery will not recover.

Put ammeter in series with the battery circuit. Use lowest ammeter setting. If there is current flow, then there is a parasitic load (drain) on the battery. Need to determine what is causing it.

When a battery is marked with TSO authorization that means it has met the Minimum Operational Performance Standard (MOPS) of the TSO specifications. TSO specifications are independent of the battery's intended installation on an aircraft. A PMA'd battery is approved for installation into a specific aircraft model.

Visit the Concorde website: www.aircraft-battery.com. You can search by aircraft type and model. You can also search by specification. This allows you to determine if the battery you have selected will meet the technical specifications defined by the aircraft manufacturer.

Do a condition charge(s) per the CMM Document No. 5-0171. This may restore your battery capacity. If it doesn't, then you will have to replace your battery.

Boost charge the battery per the CMM. The voltage should recover fairly quickly. If it doesn't, then contact your distributor for a replacement battery.

This happens to all lead acid batteries. The active materials on the plates convert from lead and lead dioxide to lead sulfate whenever a battery is discharged. The battery starts to discharge as soon as you turn on the battery master switch to start preflight operations before engine start! It can also be the result of a parasitic load (drain). Time and temperature are the enemy. The longer the battery stays in a discharged state, the more pronounced the lead sulfate crystals become. Over time, it beomes very difficult, if not impossible, to convert the lead sulfate crystals back to lead and lead dioxide. A condition charge can help reverse this process. The key consideration, get the battery re-charged as soon as possible!
