CTEK Multi XS 800 Battery Charger

The CTEK XS 800 battery charger is designed for use with small 12-volt batteries such as are used on small cars, motorcycles, lawnmowers and jet-skis. It’s also useful for maintaining batteries up to 60Ah on vehicles which are used infrequently.

Like all models in the CTEK range, it can be safely left connected indefinitely to ensure that a battery is in peak condition when it’s needed. It is completely safe and can even be left out in the rain.

It’s designed to charge 12V batteries of up to 32Ah capacity at a constant rate of 0.8 Amps per hour.

*) Back current drain is what drains the battery if the charger is connected without the power cord connected. XS 800's extremely low back current drain corresponds to < 1Ah per month. Many other chargers have 1Ah per day.
**) 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. XS 800's ripple is only 2%. The battery gains a long service life and there is no risk of damage to other electronic devices connected to the battery.
