★★★★★5.01 review
Review summary will appear here when enough rider feedback is available.
TecMate was founded on 1st September 1994 in Belgium, to continue the development and manufacturing of professional battery charging, battery testing and engine troubleshooting and tuning tools aimed at the power sport, marine, automotive, light aircraft and industrial equipment industries. TecMate's professional charger knowledge and experience led to the design of the OptiMate battery saving charging method in 1995, with the purpose of saving AGM, GEL and STD lead-acid batteries that have stopped working simply due to neglect. OptiMate now also charges, tests and maintains lithium (LiFePo4) batteries.
