8-step 12V 10A/24V 5A Battery Saving charger-tester-maintainer (BC - California & Oregon approved)

The world’s most advanced 12V & 24V battery charger!
OptiMate 7 12V-24V is perfect for high performance 12V and 24V starter and deep cycle batteries that demand accurate temperature controlled charging and unsupervised safe long term maintenance.

Designed for sensitive electronics:The SAVE program has been designed for SAFE fully automatic low volt start (from 0.5 Volts) and PULSE recovery of deep discharged batteries connected to very sensitive electronics e.g. light aircraft, industrial equipment.

Protection against incorrect voltage selection:With 24V selected and a 12V battery is connected OptiMate 7 12V-24V will immediately warn that a low voltage is sensed and then not proceed to charging. USER must confirm the nominal voltage of the connected battery is 24V before SAVE mode activates.
