Battery Tender
A battery tender is a smart maintenance charger that keeps a parked motorcycle's battery topped up over long idle periods.
[VERIFY] What is a battery tender? A battery tender is a smart maintenance charger left connected to a parked motorcycle, monitoring the battery and topping it up only when needed rather than charging continuously. Motorcycle batteries are small and many bikes draw a little current even when switched off, so a bike parked through a season often will not start without one. The term is a genericized brand name — riders use it for maintenance chargers in general, and compatibility with lithium batteries in particular depends on the specific charger.
