How do you charge a 8 volt battery?
Using a standard 12 volt car charger, the charger will charge a lead-acid battery to 13.8 volts, or 2.3volts per cell. For an 8 volt battery this is 9.2 volts for a fully charged 8 volt battery. To use a 12 volt charger, connect a 4.5 ohm 10 watt resistor in series with the charger to the battery. This will limit the current when fully charged to about 1 amp since as the battery charges, the voltage will rise and approach 9.2 at the battery and 13.8 at the charger.
