Trickle battery charger will kill good battery when left on for long time.
There is lot of confusion in naming the chargers, so read the manual for proper explanation.
What you need for long storage is BATTERY MAINTAINER or charger with FLOATING CIRCUIT who will never go above preset voltage, usually 13.6 V.
I have bunch of them for my motorhome, tractor, PWC and some other toys.
Bought them at HF for $4.99
