Frequently Asked Questions (FAQs)
1. How many amps does a car battery charge at?
A basic charger usually charges at around 2 amps - and so needs 24 hours to deliver the 48 amps needed to fully charge a flat, 48 amp hour battery. But there is a wide range of chargers with different charge rates on the market - from 2 to 10 amps. The higher the charge output, the faster a flat battery is recharged.
2. How do you calculate battery charging units?
T = Ah / A So charging current for 120Ah Battery = 120 x (10/100) = 12 Amperes but due to losses, we can take 12-14Amperes for charging purpose. Suppose we took 13 Amp for charging purpose, then charging time for 120Ah battery = 120 / 13 = 9.23 Hrs.
3. What is the unit of car battery?
Ampere (Amp) Hours A unit of measure for a battery's electrical storage capacity, obtained by multiplying the current in amperes by the time in hours of discharge. (Example: A battery which delivers 5 amperes for 20 hours delivers 5 amperes x 20 hours = 100 Amp-Hr of capacity.)
