8 Volt Battery Chargers and Maintainers

Flat Rate Shipping $7.50 per Qualifying Order

There are not a lot of 8 volt batteries used these days, which leads to a small market for 8 volt chargers. The chargers that we have selected below are the units that we highly recommend for proper maintenance of your 8 volt battery. They are fully automatic, and will not overcharge your battery, even in long term storage situations. So, if your antique car or tractor has an 8 volt battery, you can be sure that any one of these will keep your battery in tip top shape for the long haul.



How do you know if your battery is 6 volt, 8 volt or 12 volt?

Simply count the number of cells. You can do this by counting the number of round individual cell caps, or removing the 'strip' type cell vent covers and counting the access holes for each cell. Each cell accounts for 2 volts(2.2 actually). So if you have 3 cells, it is six volt, 4 cells is 8 volts, and so it goes.

Do NOT use an 8 volt charger on a 6 volt battery. Bad things will happen. Do not use a 6 volt charger on an 8 volt battery, it will actually discharge it. Look here for more info on how batteries work.
