The line of Sentry SFR chargers is in an elite class, setting the standard for dependable battery chargers. Sentry chargers are designed to operate for decades in the harsh marine environment. They are completely field serviceable and come with a 2-year parts and labor warranty.

Sentry SFR battery chargers are designed for fully automatic, unattended operation, with charging outputs for Lead-Acid, AGM, Gel and Lead Calcium batteries. Once batteries reach full charge, Sentry chargers turn off completely. There is no output trickle to overcharge or dehydrate batteries. Additionally, optional temperature sensor reduces output to prevent overcharging.

Sentry chargers have negative ground with three outputs, allowing three separate banks of batteries to be charged simultaneously. A fourth output is available on some models.

For long voyages, Sentry SFR is the charger to have aboard. The manual automatic switch allows you to bypass the voltage regulating circuit, and most repairs can be accomplished with just a few spare parts.

Front-panel includes LED charge status and fault indicators and manual automatic selector switch.

All models are current limited and ignition protected for engine room installations.
