Storage
The 12.8V LiFePO4 battery can be stored in an environment with temperatures
between -40°C and +60°C and between 10% and 90% relative humidity, non-
condensing. For long storage periods at 25°C, charge the battery every year. For
temperatures above 40°C, charge the battery quarterly. Do not store the LiFePO4 battery
at temperatures above 60°C.
Relationship Between Charge Limits and Temperature
Due to the chemistry of Lithium-Ion cells, the cells cannot accept as much charge current
at lower temperatures without risking permanent loss of capacity. As the cells’
temperature rises during the charging process, they can gradually accept higher currents.
To maintain optimal performance and durability of LiFePO4 battery, the following charge
limits based on ambient temperature is recommended.

Note:
Battery cables (not included in the battery purchase) should be appropriately sized to handle
the expected current.
