battery is at high ambient temperature and/or the charging voltage is set too high.
Take the following precautions:
● Charge batteries in accordance with the instructions given in this manual.
● Do not install batteries near heat sources or in direct sunlight that may
artificially elevate their temperature.
● Never use another charger not designated by the manufacturer - OEM

As of this writing, Concorde does not know of any Lifeline® AGM batteries that
have failed due to thermal runaway. See the LIFELINE® TECHNICAL
MANUAL for full SAFETY INFORMATION.
The temperature of the battery has a significant impact on its performance and life
capability. Battery capacity is reduced significantly in cold temperatures.
It should be realized that the temperature of the battery itself and ambient
temperature can be vastly different. While ambient temperatures can change very
quickly, battery temperature change is much slower. It takes time for the battery to
absorb temperature and it takes time for the battery to relinquish temperature.
If the battery is exposed to cold climates, the state of charge should be kept at a
maximum to prevent freezing of the electrolyte. A fully charged battery will not
freeze even under the coldest weather conditions, but a discharged battery will
freeze even when moderately cold.
Frozen batteries are not capable of charging or discharging except at very low
rates, and may be permanently damaged by expansion of the electrolyte. A battery
pack with a state of charge of 25% can freeze at 9 degrees Fahrenheit or a battery
pack ran all the way down to cutoff can freeze at 21 degrees Fahrenheit. A 100%
charged battery pack would have to get colder than -94 degrees Fahrenheit to
freeze.
Lifeline® AGM batteries do not need electrolyte additions as do flooded lead-acid
batteries, but periodic servicing is essential to assure continued integrity of the
battery system. Servicing should include good record keeping documenting the
life history of the battery system and to identify whether corrective action needs to
