It depends on how long you can let it sit before you need to use it. If you have 8 to 10 hours then a setting of 2 amps is appropriate. For a quicker charge then 12 to 20 amps is recommended.

Can 5v charger charge a 7.5v battery?
yes it just takes longer to charge, but check how much Amps (A) your charger gives out and how much Amps your battery can take if the battery has lower Amperage (A), don't do it, otherwise you're fine. <<>> No, the charging unit has to have a higher output that the battery voltage that it is charging. For example, on a 12 volt car battery the charging rate is 13.5 volts.
Why does a car battery bubble when charging?
"Bubbling" of Electrolyte in Vehicle Batteries While ChargingThat is usually caused by having the charging rate[Amperes (Amps)] set too high.
Can you use a 2Amp Car battery charger on a 12 volt sealed leak proof battery?
First the maximum charging current for the battery should be checked. If that is unknown it can be taken as one tenth of the capacity, e.g. 2 amps max for a 20 Ah battery
How many amps do you need to charge a car battery?
To charge a car battery you need aproximatly 8000 amps To charge a car battery you need aproximatly 8000 amps
Does quick charging a battery hurt the alternator?
if you boost charge a battery you should discinnect it from the car. if not you may burn out the alternator
Why your car battery not charging back?
charging system not charging battery with new batttery, alternator and fuel pump. what will make that happen ?
Is charging of car battery chemical change?
Yes. The charging causes a chemical change in the electrolyte of the battery.
Should your car turn off while is running if it has a bad battery?
If the cause of the dead battery is from the charging system failure, yes.
Why does a battery charger produces a higher voltage than the battery being charged?
Battery chargers generally operate at the same voltage as the voltage as the battery they are charging. They usually vary the amperage they feed into the battery to recharge it. A trickle charger usually only feeds a few amps into a battery to recharge it slowly over time. A fast charger feeds more amps for less time to bring the battery to full charge faster. Automotive alternators are the only charging systems that I am familiar with that generate more voltage than the battery they are charging. That's because they have to run the car AND recharge the battery at the same time. Car alternators can vary their amperage and voltage outputs to allow for the varying demands of the car and all of it's electrical devices and recharge the battery as needed.
Can you use a van battery with higer amps in a car that had a battery with lower amps?
Yes, there is really no van battery or car battery. There is just an automotive battery. Installing a battery with more Cold Cranking Amps (CCA) is fine and will just provide more power in cold temperatures.
Can you drain a car battery by charging another car battery?
only if the car your using to charge the other on is not started
Your 1997 Mazda 626 will not start after an alternator malfunction why?
Battery will be flat because spark plugs were running straight off your battery because the alternator was not charging your battery as you were driving. You can test this by jump starting your car with another car and after your car is running you should be able to disconnect your battery and car should still run off the alternator. If your car stops than your alternator is RS. Battery will be flat because spark plugs were running straight off your battery because the alternator was not charging your battery as you were driving.
