A dead battery will NOT get fully charged by a trickle charger, and might not even charge at all!
A trickle charger, battery maintainer, is just that. To keep a battery at the fully charged state.
It doesn't have enough charging power to revive a dead battery.
Also the charging system on the bike doesn't like to have to charge up a fully dead battery.
Its hard on the components. That's why a new battery always states to charge the battery before installing it.
Please only jump your bike with a bike battery. Not a car battery.
OR just push start it !
