Related Questions and Answers
How do I know what size battery charger I need?
Calculate the charger size using the battery ampere-hours ((AH x K)/T) + L = I formula.
The battery’s ampere-hour capacity is measured in AH. ((45 x 1.4)/24) + 0.8 = 3.425 amps
K is the battery recharge inefficiency constant (1.15 for lead-acid and 1.4 for Ni-Cd).
What is a good size battery charger?
As a matter of thumb, your battery charger should be at least 10% of the battery’s Ah rating. A 100Ah battery, for example, would need at least a 10 Amp charger. To avoid overcharging, limit the charger’s capacity to less than 20% of the entire capacity.
How many amps do I need to charge a 12 volt battery?
The charger should be roughly 25% of the battery capacity (ah = amp hour capacity), according to most battery manufacturers. A 100 ah 12 volt battery, for example, would need a 25 amp 12 volt charger (or less). Larger chargers may shorten charging times, but they can also shorten battery life.
Can a battery charger charge all types of batteries?
Is a special charger required for stay-charged or low-discharge batteries? No, any NiMH rechargeable battery charger compatible for stay-charged or standard rechargeable batteries will charge both stay-charged and normal rechargeable batteries.
Can a small charger charge a big battery?

What happens if you charge a battery with too many amps?
Amperage Available vs. Amperage Required Depending on the degree of the discrepancy, the device may fail, run or charge slowly, the power source may overheat, and the gadget being charged may be damaged. The amperage offered by your charger must be equal to or more than that required by the item being charged.
Does higher amps mean faster charging?
“In the end, the amperage is what decides how quickly a charger will charge your gadget. Look for a wall or vehicle charger that generates 2100 mA of current at 5 volts (or whatever voltage the item you’re attempting to charge is specced at) if you want to charge it faster.”
