How many amps are needed to charge a scooter battery?
The amount of amperage needed to charge a scooter battery depends on the voltage of the battery and the type of charger being used. As a general rule, a battery charger will pull two amps of current until the battery reaches a fully charged level of voltage. This is known as a high current fast charge.
First, find out the capacity of your battery in terms of rated voltage and amp per hour. For example, if the battery says 24V8Ah, it means the battery can be safely discharged 8 Amps at 24V for one hour. Theoretically, the discharge current is two times of the charging current without damaging the battery when discharging. Second, make sure the scooter battery charger’s output voltage matches the battery’s rated working voltage. As a rule of thumb to safely charge the battery without causing damage, choose the charging current to be 1/4 of battery’s rated discharging current. If the battery is 24V8A, the charging current should be no high than 2A.
