Truecharge 40+
Smart, Multi-Stage Battery Charger

Micro-processor controlled, 40 amp continuous duty, multistage battery charger

Our 40 amp micro-processor controlled battery charger quickly recharges up to 3 deep-cycle battery banks, and knows when to stop charging to avoid cell damage. This unit accommodates 12 volt lead acid batteries from 200 amp-hours and up.

Ideal for deep-cycle marine, RV, and industrial batteries, the TRUECHARGE 40+ is designed for batteries from 200 amp-hours and up. The TRUECHARGE 40+ offers three-bank battery charging capability with one charger.

Microprocessor controlled, it provides fully automatic battery charging for faster charging times than many 75 and 80 amp rated ferroresonant battery chargers. This is made possible via the four-stage charging capability of the TRUECHARGE 40+.
