When TecMate exhibited at the Indianapolis Dealer Expo in 2010 , CEO / CTO Martin Human was on a mission - to research the emergence of lithium batteries , a then new power source that was said to be a more powerful and lighter aftermarket replacement for lead-acid batteries . Following visits to the likes of Shorai , Ballistic and other exhibiting battery companies , it became apparent that there was a need for a dedicated aftermarket battery charger for lithium batteries - one that could be relied upon to safely recharge the battery , especially from a deep discharged state , which is when it is most vulnerable to damage . Following his subsequent research into the specific lithium technology primarily in use at the time - namely Lithium Ferrous Phosphate ( LiFePO4 , also known by its acronym LFP ) - the OptiMate Lithium LFP 4s 5A ( TM-290 series ) was released in 2012 . It quickly became the reference charger for powersport lithium batteries , endorsed and globally recommended by Honda , Kawasaki and Yamaha as the lithium battery charger of choice for their worldwide network of dealers . It also formed the basis for other OptiMate lithium battery charger models that followed , including the highly popular ' riders ' charger ', the OptiMate Lithium LFP 4s 0.8A ( TM-470 series ), also endorsed and recommended by Yamaha and Kawasaki . Ten years on , and lithium starter batteries have reached ' mainstream ' level , with motorcycle OEMs now releasing models with a lithium battery as stock . Motorcycles have also ' moved on ' in technology , with electronically adjustable options for suspension , engine power and torque and ride modes , with larger screens that display and connect with phone and GPS information . Many rider options remain only selectable when the engine is not running , for obvious safety reasons . That can be a problem for the smaller lithium battery that typically has two to three times less amp-hour capacity than the lead-acid battery it replaced . Some advanced lithium batteries include resettable protection against deep discharge , turning off power when the lowest allowable charge level is reached , but a standard lithium battery should not be discharged too low . Martin says that " the new OptiMate Lithium LFP 4s 6A ( TM-390 series ) addresses all those concerns . It includes all the safety and charging features of the ground-breaking TM-290 series , and it offers two more features to cope with modern demands . " A TUNE mode that delivers a stable 13.6V with up to 5 amps of power that protects the battery against discharge when the parked motorcycle ' s rider settings are adjusted . " The second is a pushbutton activated BMS reset function that will reset and re-energize a battery with built-in deep discharge protection . " The OptiMate Lithium 4s 6A ( TM-390 series ) replaces the OptiMate Lithium 4s 5A ( TM-290 series ), and is now available from TecMate worldwide , including the newly formed TecMate Japan ."
