Yes I already know about that. If you are using a standard battery tender you can not charge this battery for more than 10 min., so I always set the timer on my phone for 10 min., but I rarely need to charge it, I do anyway if I'm doing maintenance and have the seat off. There is a special smart tender made to leave connected to these lithium ion batteries which I don't have the need for. Racers that live in cold weather states will remove their batteries from the bike and leave them hooked up to the tender for the winter while their bike is in storage.Watch out for the correct battery tender for charging those light weight batterys. .
yeah this is standard practice with the guys racing sportbikes because not only do they want to trade $ for weight but on bikes like the zx10r many have problems with the OEM battery not giving enough power to the ECU so error warning lights come up on the dash all the time. Replacing with a good lithium ion solves this.I believe these hold a charge better and overall have more juice in them. So not only do we shave weight but also have are more dependable battery,
