    Battery Tender - not during storage?

    I use to do this with all my motorcycles, i have a battery tender for every one of my toys, and on the motorcycles, i have a plug and go connection, since any one of my vehicles can sit for 1 to 6 weeks before i ride them, i always leave them plugged in...

    Now new to jetski's i have a 2003 polaris MSX 140 and a 2009 Yamaha Fx SHO Cruiser. my question is this:

    can i keep the jetski batteries hooked up to a battery tender at all times without disconnecting the leads to the watercraft? or will the charger possibly damage the EMM or other components of the boat.

    No problem at all.

    As long as you are using a decent quality Battery Tender brand, or CTEK, BatteryMinder, or one of the other well made battery maintainers.

    There are a couple of threads elsewhere showing different ways to bring the charger cord out of the hull. Search for Marinco

    We have seen problems/damage when people use automotive chargers, that are too hefty for the small PWC batteries, or boost from running cars/trucks, etc.

    A properly connected and operated battery maintainer is a good thing.
