Optimate IIISP is the most advanced fully automatic diagnostic battery charger and maintainer for all 12v lead-acid batteries from 2,5 to 32 Ampere-hours capacity.

All major starter battery manufacturers recommend maintaining such batteries FULLY CHARGED during periods of non-use.

Optimate IIISP is totally safe for months-long connection and maintenance of irregularly or seasonally used batteries even while still connected to the vehicle. No risk of over-charging. Electronically protected against user errors.

Just connect the Optimate IIISP to your battery, the rest is automatic. There is no switch, no fuse… and there are no sparks. De-activates automatically if connections are broken

Optimate IIISP’s unique diagnostic function automatically identifies deeply discharged (sulphated) batteries and applies a controlled high voltage with small fixed current for a limited period to recover them.
