*) Back current drain is what drains the battery if the charger is connected without the power cord connected.

**) Ripple denotes the amount of interference there is to the current and voltage. A high current ripple heats the battery and shortens its life. A linear charger has a current ripple of 70 - 400% which is much larger than the maximum 5% for a modern sealed battery. Voltage ripple could harm other equipment, which is connected to the battery. The MULTI XS 7000 delivers voltage and current with very low ripple. The battery gains a long service life and there is no risk of damage to other electronic devices connected to the battery.
