How Many Amps To Charge 12 Volt Battery. Thereof How long does it take to charge a lawn mower battery at 2 amps. 12 volts with at least 600 available Amp.
In other words we can draw 48 amps for 10 20 or 100 hours before the voltage falls down to 10 volts the discharge range. 500 Amp-hour battery x 30 150 Amps to charge up the battery. A 10-amp charger will give you a quicker charge and is still relatively safe though you should take care to remove the charger as soon as the battery is full.
A word of advice.
138 to 150 volts. Suppose we took 13 Amp for charging purpose. To get Wattage you simply multiply the Amps needed by the Volts. As a battery is charged the indicated voltage increases and as discharging occurs the indicated voltage decreases.
