The CTEK800 battery conditioner uses the same PRIMARY SWITCHED electronics to make it the most advanced conditioner available today.

The CTEK800 is designed for keeping good batteries in good condition. The conditioner constantly monitors the voltage after it has charged the battery to 14.4v and then only pulse’s the battery when the voltage drops due to alarms or natural drainage. This eliminates the danger of over charging the battery allowing it to be left connected for many months at a time.

The XS800 will charge the battery to 95% at 0.8amps, it will then reduce its input current to 0.4 amps to slowly bring the battery to its maximum voltage before turning off and waiting for the battery to fall to 95% efficiency (approx 12.9v) when it will turn on again and condition the battery back to 100%
