Dead battery

[95xpyellow]

I let a battery I bought last year sit thru the winter. It won’t take a charge now. The meter reads 2.4V.
Is there a way to save this battery? Or at least get enough of a charge to start it to show a potential buyer my Sea-Doo?

Nope, not when it’s that low.

And do not boost or jump start the ski or you can fry the computer.

You can use jumper cables to a NOT RUNNING vehicle but don’t mix up the polarity.

So I can use the dead battery and hook it up to a not running vehicle and start the Sea-Doo safely?

It might start, but don't shut it off.

Like you said, it won't take a charge. You need to replace the battery. I pull all my batteries and charge them for 24 hours once a month at 2 amps all winter. Even a new battery can go bad over the winter without doing a maintenance charge.

Not to thread jack, but is this better than leaving it on a trickle charger all winter (meaning, leaving it constantly hooked up)? Just curious as I just bought a new battery and don't want to mess it up this winter.

I’m terrible with batteries. I put them on the shelf and forget about them. I have to buy a new one every year. I’m curious to I’m going to give a better effort this winter

I know they make maintenance chargers that hold current low that you can leave on all winter. I had one, it died and I never replaced it. You don't want to leave on a 2 amp charge all the time, that's why I do 24 hours once a month.

Get a BatteryTender as they are computer controlled and can be left on all year. I typically get 5 years out of my batteries using a batterytender.
