Craig,
I still woulda taken the battery out of the truck and worried about getting home after a day of boating

If they are deep cycles, I believe that you need a special charger for them. As to them being drained, this is what they were meant to do. They are built heavy duty to be drained down and recharged. What they can't do is supply alot of current quickly for a starting application. That's why I always liked the dual purpose batteries for a marine application.

Craige you are probably OK. The real question is will you be wondering about them? If so just go get new ones it is cheap insurance and one less thing you will worry about.

Craig I am a bigger idiot for wrecking batteries in fack I will start a thread on it

Update... I went down to the river after charging both batteries yesterday afternoon. The engines started without jumping them and ran like a raped ape! I cut them off a few times and they started fine.

I guess the next test will be if they hold the charge and start this weekend. If not, I'll buy two new batteries and be done with it.

Thanks for all your replies, Craig

Yeah, the good warranties only come with the automotive batteries. If you normally run your batts down under 11 volts then these aren't going to like it as well as a true deep cycle. But then again, they got 3 yr free replacement and 96 months of prorated warranty.

I've been running them since 1999 and so far, I've had zero need to replace. I don't run under 11 volts, though.

Hopefully you got your batteries back to life. I would be suspect of the bilge pump at this point. They don't usually like running dry for hours. Pumps are cheap. You might want to replace it now before you really need it.

Good luck.

you're bilge pump does'nt have a float switch??

Craig,

I replaced my bildge dash switches to momentary in the on position so I could not leave them on
The auto position stayed the same as it went through the float
The motors are in my garage finally both dynoed I am just dressing them and hope to be in the water soon and still amke a trip out there later this fall

Good thing to keep in mind. Trying to charge a dead battery with your alternators is HELL on them (the alternators). You were smart to get them on the charger to bring them back. Old batteries will kill alternators as well. It is good to keep your eye on them and make sure they are ok so that you do not have to do batteries and alternators.
