CTEK d250s dual battery charger

Description

The CTEK D250S Dual charger hooks up to the starter battery, then uses the vehicle alternator to charge the service battery while driving. This device is a fully-automatic, 5-stage charger that supplies 20 amps to 12V batteries, with a battery separator. But notably, it can also draw power from solar panels (not included) whenever the vehicle is not running and comes equipped with a Maximum Power Point Tracker (MPPT) so it can work as efficiently as possible.
This will then charge and maintain both the starter and service battery while you enjoy the great outdoors.
For faster charging, the CTEK D250S Dual charger comes with a battery temperature sensor. This enables it to increase voltage in cold weather to ensure the battery is fully charged, or drop voltage when its hot to avoid overcharging.
