Thread: Battery tender?

  1. #1

    Battery tender?

    Hey guys quick question. Well I got a new gtr 215 and this thing is awesome. Thanks everyone that has helped me answer all my questions as I'm new to the 4 stroke world of this. That being said the dealer told me these batteries are not no 50 dollar battery closer to 200 and can only be bought at seadoo?

    Well anyways i was wondering if you guys keep a charger on em and what's a good one to get? I'd like one that can stay in there and I just plug it in. I have not got to take ski out in about 2 weeks idk how long is to long to leave em sitting.

    First of all congrats on your ski!!

    Second of all, yes, you do want to use a battery tender if it going to be a while before you ride again. I tell everyone who buys a ski from me that you are ok to go about 3 weeks between riding without charging. After that you will want to charge the battery with no more than 2.5 amps.

    There are a lot of people here who think that a battery tender is the devil and that you shouldnt use them. They wont save a dead battery, they will help a battery from going dead...

    If you go more than 3 weeks without a charge, sure the ski will start but it might be slow to start and not charge fully and then you will be buying a new battery..

    You do not have to get the battery from a dealer only. If you get the factory Yuasa battery, just make sure you get a 30 series. If you get an aftermarket AGM battery, you MUST get a 30LA. The AGM batteries are a little shorter than the factory one and they require a spacer plate that comes with the 30LA.

    No let the flame war begin as to why I shouldnt charge my battery....

    I typically wire in a charger ring terminal connecting cable and zip tie it out of the way near the top of the seat opening. Then it is easy to connect up the charger to the handy connector.

    Be sure to buy and use a smart charger that senses battery charge state and properly switches to 'float' mode once the battery is fully charged. The actual Battery Tender brand products are OK.

    You can leave it on a battery tender brand float charger indefinitely. Google it, I'm sure you'll find how it works scientifically.

    I second Battery tender as a brand. I put off buying one for quite awhile, now I use it for everything and always advise people to get one. They're SUPER simple to use and the batteries last a very long time when you use them as directed.
