What this means
- The maker's statement. What each maker states the battery does below freezing.
- LiFePO4 cells must not charge below freezing. A cut-off stops charging; a self-heating battery warms its cells first and then charges.
- Heating uses the charge current. A heated battery draws on the charger, not on itself, before it charges.
