    Trickle Charger - Battery still connected?

    Hi All.

    I have a 2006 GTX Limited.

    I wanted to know if it's OK to use a trickle charger (or any charger) on the battery while the battery is still installed in the ski?

    Or do I need to disconnect the battery completely, or the positive cable at least?

    Thanks !

    I've been doing it for years. No issues with leaving it connected here.

    Thanks for the response.

    Which Battery Maintainer do you use/have?

    I've got a Deltran 800 (800 milliamps) waterproof maintainer, as well as the larger automotive charger.

    I have read I should push a lot of amps to the battery (it's an AGM) and so should use the maintainer.

    I wanted to buy another Deltran like the model 800 I have, but I think they discontinued it.

    Never had an issue charging through the winter with it still connected in the craft.

    There seems to be a lot of confusion about battery charging and battery maintaining. These are different things.

    Battery lifespan is maximized when the battery voltage is held at the optimal float voltage for the battery with 100% charge. Not overcharged, not undercharged. This is specified by the battery manufacturer. Optimal float voltage varies with battery type and temperature. Some battery maintainers have temperature compensation which can adjust the float voltage as the temperature charges.

    AGM batteries (as found in Powersports) do well with a medium fast charge rate and can accept a heavy charge rate just fine. I use a BatteryMinder 8 amp charger. If I want to push a lot of charge to pump the battery up from a low charge state I may use the 8 amp rate. Most of the time for a charge top-off I will use 4 or 2 amp rate on the charger. In all cases the BatteryMinder switches modes and tapers the charge current and voltage as the battery charge % rises.

    Once the battery is fully charged, you do not want to ‘push a lot of amps’ into any battery, AGM or otherwise. A modern decent quality smart charger should automatically reduce the charge rate as the battery approaches ‘full’ and then switch to a float voltage mode.

    Float voltage does not ‘push’ a strong current into the battery. Float voltage simply maintains the battery at 100% charge, or close to it. If the battery is well below 100% the float voltage can slowly increase the charge level, eventually getting to near 100%

    The Deltran 800mA waterproof charger does charge and then maintains the battery with a float voltage mode.
    This is what I use for longer term storage.

    The bulk mode (full charge, constant current, battery is 0% to 80% charged),
    the absorption mode (high constant voltage, battery is 80% to 100% charged),
    or the storage/float maintenance mode (low constant voltage, battery is 100% to 103% charged)...

    ...

    GREEN LIGHT ON STEADY –When the green light burns steady, the charge is complete and the battery can be returned to service if necessary. It can also stay connected to maintain the battery for an indefinite period of time

    Thanks for that info tiderider.

    I like my Deltrans 800 that I have now. I like the fact that it's "waterproof" and can hang outside if need be.....

    The reason the manual says not to charge while installed is due to fuel vapor that could ignite. keep the seat or hatch open and a charger that won't spark, you're good.
