Cotek's line of 12v and 24v CX chargers include all of the features you expect from a high quality battery charger. Cotek CX chargers are compatible with all common battery types including Lead Acid, Li-ion, Gel and AGM. Cotek chargers have some of the most advanced safety and technical features out of any battery charger and in our experience Cotek products are extremely high quality with some of the lowest failure rates in the industry.

Cotek CX chargers are available in 12v and 24v versions in a wide amperage range. Cotek CX battery chargers are ideal for use with a generator in an off-grid system for recharging batteries as a backup power source during equipment maintenance or prolonged periods of overcast weather. Most off-grid systems will need a battery charger and backup generator and the Cotek CX chargers are ideal for inverter systems where there is no built-in battery charger such as Cotek's line of high quality sinewave inverters. CX chargers can also be used in battery-backup applications and are used in our own Rolling Thunder RT-1000 backup unit.
