If you have a 6V battery in your vehicle or device, it is always best to use a matching 6 volt charger to keep it topped off. Alternatively, you may use a charger that has a variable voltage setting, which can be set to 6V for this purpose. This will ensure that your battery is properly charged without a problem. A 6V battery is actually fully charged when it reads slightly over 6V on a multimeter. 12 VOLT BATTERY CHARGER FULLĪ 6 volt charger is typically designed to produce about 7 volts so that it can attain a full charge. Can I Use a Lower Voltage Charger?īattery chargers come in a wide range of configurations, so you may find that you have a 2V or similar charger on hand. While it is possible to charge a 6V battery with a lower voltage charger, there are a few things you need to be aware of. First, it will take a very long time for the low voltage charger to work on your 6V battery. Think of it like setting up a trickle charger, which will charge your battery over the course of 10-12 hours, instead of 1-2 hours.
Secondly, a lower voltage charger will never be able to produce enough power to fully charge your 6V battery. It might charge your battery enough for you to get your device jump started, but that's about it. After that, you will still need to go find an appropriate charger for your battery if you want to continue using it.
