I hope I didn't...

Don't think that is enough difference to say the old one is bad. 6 amps is best for sure. Get the on board charger and be done with it. You'll be glad you did.

.2 ain't much. I'm thinking your 6 amp charge just might have done the trick. I'd like to see the fully charged reading be a little higher, but you're right in there. You did check the water right? Only fill with DISTILLED WATER!!!!

And DON'T overfill like I did. Will eat right through your metal boat.

Thanks fellas.. Yeah I am definitely getting the onboard charger. Either moving the water filter and mounting it there or just mounting it somewhere on the back of the boat.

I checked the water in both of the batteries.... They seemed full to me. I am not real sure how much water is suppose to be in the batteries but the water was about 1/2 to 3/4 inch from the top of the battery. It didn't look like it could hold any more water. So I didn't add anything to it. Just put the top back on the battery and left it alone.

Wannabe... What is the normal reading for a 12 volt battery on full charge? I was thinking it should have been a little higher also.

This is what you (and I) need to get. NAPA probably has them, Torch?

DG, you should really be between 13 and 14 on a full charge.

Pretty niffty jug there major... I like that...

Triton - that makes sense. I know that the voltage on my cranking battery will be up around 14 right after turn the motor off. That is according to my 898. I thought that might be a little low for a full charge. That might be why I am not getting 6 hours like I use to get. I think my charger is a piece of crap. Hope to by the on board one this week.

From Memory, I think it's 13.4 Volts according to what I've read, but in all honesty, I've NEVER gotten that reading on any battery I've ever owned whether new or old. Best I've ever gotten was 13.0.

That volt reading also does not necceasarily mean a battery is any good. Check your specific gravity readings with a hyrdrometer on each cell....if one is a good bit different than the others then you have a bad cell. The best test is to test with a load tester.
