Modern Cristec battery charges intelligently charge your batteries and stop charging when the batteries are full so they can always be left switched ON.

Yes. You can program battery type using dip switches under the cover or by using the app on the new Ypower plus models.

The main roll of the battery charger is to maintain the domestic house battery bank which is in constant use. The capacity of each battery in the house bank will be marked in amp hours (AH). These values should be totalled and divide by 10 equalling the minimum sized battery charger size that should be used. To determine the biggest charger that can be used, you can dive the capacity by five or by 3 if lithium batteries are being used. This calculation is best suited to boats often charging batteries offshore from generators.

The charger battery type would normally be set to correspond to the largest house battery bank except for lithium combinations. Lithium batteries should have a dedicated charger as not to damage any lead batteries in the system.

The Cristec chargers are often silent so it can be difficult to tell if they are charging the batteries. On the front of the charger is two lights, one indicating the unit has power and the other for charge profile. If you have no lights illuminated, you should first ensure the charger has power. If the power light is illuminated but there appears to be no output, the out put fuse may have blown. To check the fuse, you must disconnect power from the charger and open the cover of the charger to reveal the fuses.
