A Perfect Charge battery charger is designed to get the 12-volt battery in your vehicle, motorhome or boat running. Both Perfect Charge W6 and W8 are resistant to short circuiting so that operating errors will cause no damage. The operating and charging states are indicated by LEDs and both chargers are standard with automatic protection. They will both switch off automatically when the full charge is reached. This prevents overcharging of the battery and there’s no need to supervise the charging process.
