TecMate Optimate 1 Battery Charger

The TecMate OptiMate 1 is very easy to use, simply connect to the battery and plug it into the nearest power socket, the rest is fully automatic. OptiMate 1 automatically brings the battery to full charge and then switches to float mode at a safe voltage limit to keep the battery at 100% ready, never overcharging, and at the same time provides power to the on board computer, display or anti theft alarm. Safe for use with  STD (with removable filler caps), sealed AGM (absorbed glass mat) & sealed GEL 12V lead-acid batteries up to 50Ah, it can also maintain larger batteries (it will just take longer to charge).

TecMate Optimate 1 Battery Charger 1 5 1 1
Will not charge a discharged battery It will maintain a battery, but It will not charge a discharged battery. There is very fine text in the manual that says it won't charge a battery that shows less than 8 Volts. There are plenty of cheaper chargers out there that will. Don't buy this one. March 5, 2013
