TecMate OptiMate 3+ Battery Charger and Maintainer

The TecMate OptiMate 3 Plus desulfater-charger-maintainer is recommended for STD (with removable filler caps), sealed AGM (absorbed glass mat) & sealed GEL 12V lead-acid batteries from 2Ah to 45Ah. It can also maintain larger batteries (it will just take longer to charge). The OptiMate 3 +will safely maintain the battery at 100%, never overcharging, thanks to its unique 30 min charge, 30 min rest cycle during every hour of long term maintenance charge. If the battery’s resistance is abnormally high due to sulfation, a voltage of up to 20V is automatically applied to overcome this to recover very flat or neglected batteries (when disconnected from the vehicle).
