Diagnoses, recovers, charges, checks & maintains your battery automatically for months.  All major battery manufacturers recommend maintaining starter batteries FULLY CHARGED during periods of non-use. OptiMate 4 is totally safe for months-long connection and maintenance of irregularly or seasonally used batteries even while still connected to the vehicle. The sophisticated charging algorithm ensures no risk of over-charging.

Suitable for all types of rechargeable 12V lead-acid batteries: filler cap types; absorbed glass mat (AGM or "MF"); valve regulated (VRLA); GEL-electrolyte.  As simple as 1-2-3: Just connect OptiMate 4 to your battery, the rest is automatic.  Electronically protected against user errors.  There is no switch, no fuse and there are no sparks.

Delivered with two interchangeable connection sets, one with clamps for bench charging, the other with in-line protection fuse and eyelet terminals for permanent connection to the vehicle’s battery to allow easy reconnection of charger when necessary.
