It's hard to answer this question because it depends on the charging current. Most modern chargers have some kind of indicator to let you know when the battery is fully charged but the charge current usually drops back to a minimum when it is fully charged. The battery should be marked with it's Ampere /Hour capacity. For example if it is a 40 A/H battery it can be charged at 1 Amp for 40 hours or 2 Amps for 20 hours pro rata. Add a little extra time for losses but a long 48 hour trickle charge is generally better than a short heavy charge.
You can purchase a smart charger that has a built in circuit to prevent damage to the charger or battery. I have a Black and Decker that I bought at Home Depot for twenty dollars. It is a 2 amp trickle charger that also has a 1 amp charge rate setting. It will shut off and turn on when needed to maintain a fully charged battery, so you don't have to worry about over or under charging. It's great for maintaining stored batteries also.
What else can I help you with?
What does a trickle charger do to a battery?
A trickle charger is a car battery charger that is designed to be left on a car for very long periods of time to re-charge that car battery by slowly adding charge to the battery.
Can you use any car battery charger to charge a battery from an automatic car?
As long as both batteries are the same voltage, you can jump start with the battery. If you want to charge the battery then use a battery charger.
Can you charge a battery when it is in the car?
If your leads are long enough, yes.
How long do you run your car after a a car jump?
I assume you mean how long to charge the battery. You should never let the alternator charge a dead battery if possible. The alternator is designed to keep the battery charged but not to charge a dead battery. You put a strain on the alternator and it can cause a diode to burn out. Drive home and then put a battery charger on the battery to fully charge it.
Can you charge an ATV battery from a car battery?
As long as the ATV is wired 12 volt, not 6.
How long would it take to charge a car battery with a 6 volt motor?
The car battery has 12 volts; you need MORE than that to charge it. You can't charge it with 6 volts, unless you somehow raise the voltage. In that case, how long it takes to charge the car battery will depend on the capacity of the charging device. Usually a few hours.
Can you charge an ATV battery with a car battery?
I am assuming you mean with the auto engine running. Yes, that is possible but you are putting a strain on the alternator of the car. An alternator is not designed to charge a dead battery. It is designed to keep a charged battery fully charged. as long as the ATV battery is the same voltage as the car battery, usually 12 volts, you can charge it, or jump start the atv and let it charge the battery itself.
Can you charge your car battery on a trickle charger?
Yes, but it will take a very long time if the battery is dead.
How long do you charge a 12v car battery?
If it is totally dead charge it for 2 hours at 10 amps.
What to do if my car battery not getting completely charged?
you should go to a car shop and get your battery checked and ask how long should u charge your battery.. or if you should get a new battery
How long do you have to drive around to charge a car battery after jump starting a car?
You should never drive a car around for long after jump starting a dead battery. This puts an enormous strain on the alternator. Alternators are designed to keep a good battery charged, not to charge a dead battery. You can easily burn out a diode in the alternator. Jump start the engine and drive it somewhere and connect a battery charger to the battery and charge it fully.
Can you charge battery without disconnecting from car?
yes as long as the key is off
