Batteries can be discharged over a large temperature range, but the charge temperature is limited. For best results, charge between 10°C and 30°C (50°F and 86°F). Lower the charge current when cold. Nickel Based: Fast charging of most batteries is limited to 5°C to 45°C (41°F to 113°F).
There are also other ways to charge batteries when dealing with colder and hotter temperatures. Lithium-ion batteries: A lithium-ion battery can undergo a fast charge at 41°F yet the charge rate should be lowered if under this temperature. No charging should ever be done to a lithium battery below freezing temperatures.
Therefore, the charge current and charge voltage battery's cell voltage, charge and discharge current, cell are reduced at low cell temperatures. If the temperature is temperature, remaining capacity, and run time to the further reduced to T1 (0°C as an example), the system should not allow charging.
