However, if you plan to plug more than one item into it you will need a splitter. European customers must supply their own 240v to 120v inverter in order to run the battery chargers. These new batteries are 18 amp hour units in powder coated metal boxes with two power outputs, a digital volt meter, a soft shell carry bag and a .750ma Float charger. They weigh 15 lbs and the battery is sealed lead acid. It will ruin the battery.
Automotive chargers charge at a higher voltage than other battery chargers.
If the charger charges at 14.8 volts or higher, the electrolyte will begin to turn to gas. In a normal car battery this is not a problem as the battery can be topped up. Shown below is a chart indicating how long the battery will last to a state of charge of 10.5 volts. The numbers below the hours represent the amount of amps being drawn per hour. The hour numbers indicate how long the battery will last to a charge of 10.5 volts when drawing the amount of indicated amperage.
