there are several ways you could get a charger to shut off, most of them use a circuit that detects when the draw amps get low indicating the battery has full charge. when the battery fills with electrons a back pressure or resistance goes up

What happens if batteries were charged longer?
You can ruin an otherwise good battery by overcharging it. Most auto battery chargers shut off automatically when the battery is fully charge, but there are manual chargers that do not. If you use a manual charger then be careful and do not over charge the battery.
What battery charger do you buy to charge your ford focus battery?
Any 12 volt battery charger with an automatic feature. I own a Schumacher 520A-PE and it is an excellent inexpensive charger for the homeowner. It will charge at 10 amp to recharge an auto battery in about 3-5 hours. Also has a 2 amp trickle charge to maintain a stored battery as on a lawn mower. Will shut off when done to prevent overcharging.

Remove the battery, or disconnect it, and with any 10 amp/ 2amp, charger, pos to pos, neg. to neg. and charge it at 2 amp, till it is full. If you need to add water, add only distilled water to top the battery up. Use a charger with auto-shut off.
How do you choose which car battery charger to buy?
Purchase an automatic battery charger of at least 10 amps output. Voltage has nothing whatsoever to do with what you choose. It is going to be a 12 volt output charger if you use it on an automobile. You want an automatic charger that will shut itself off when the battery is fully charged so you do not have to monitor the charger yourself. You can also buy a charger that can be used as a booster to jump start a car with a dead battery if you choose. The Schumacher SC-1000A battery charger is an excellent charger that will charge auto batteries and deep cycle marine batteries. It will charge at 10, 6, or 2 amps. It is fully automatic and sells for around $45.
Have a 480v industrial battery charger that still arcs when plugging it in after changing the 3 phase male cord cap the 20a outlet and pulled new wire?
Shut the charger off when you plug the charger into the battery. The low charge on the battery will cause arcing when brought into contact with the charger. If the arcing continues with the charger shut off check the diode bridge in the charger, there may be a blown diode gone to ground. Make sure that the output of the charger is smooth DC at the proper voltage output. If there is a problem with the battery, the over load protection on the charger will trip due to excessive current draw by a faulty battery.

How does an automatic battery charger work?
Some battery chargers have an auto-shut-off system to stop any more charge being put into the battery when it is full. The idea of this is that it should prevent the cells from "gassing", which means "giving off an explosive mixture of hydrogen and oxygen".That is why smoking cigarettes - or using anything else which makes flames, such as arc-welding - near to a battery whilst it is being charged is highly dangerous.Even so, it is still never safe to leave any kind of battery charger "on" after it has finished doing its job and the battery is fully charged.For more information see the answers to the Related Questions below.
