Charge Time = Battery Capacity (Ah) / Charging Current (A) This formula is a straightforward way to estimate charge time. For instance, if you have a battery capacity of 50 Ah and a charger that provides 10A, the battery would theoretically take 5 hours to charge. However, this doesn''t account for inefficiencies in the battery charging process.
For example: "The battery was charged at 0.5C ." It''s not temperature in Celsius, and it''s not capacitance in Farads. C-rate is current in Amperes that''s numerically equal to the capacity of the battery in Ampere-hours. Charging a 3Ah battery at 0.5C means that the charging current is 1.5A . Max charging current is usually expressed as C-rate.
