What you are looking for in an ideal world would be all batteries with equal charge but we all know what real life is like...lol. So, yes .5 of a volt could signal a problem battery and it would be the first one I would test during the hill climb test with the multimeter hooked to it. The other things that we take for granted is clean cables, properly watered batteries and hopefully no voltage drop in the cables which is a little difficult to determine but internal corrosion in the cables is a real possibility and many times a good reason to replace cables when replacing batteries.👌🏻😎

I have no idea how I'm over-charging them or how to fix this.
You can but a modern battery charger, but that's another kick in the wallet.

So my batteries look like this after 2 hours of resting, off the charger. According to the battery chart someone posted, this looks like crap. Am I right? Is there any other factor that could be contributing to these batteries not holding a charge? I just filled them with water recently and they were not in a critical spot before that.

8.26
8.22
8.22
8.25
8.21
8.23

Does it seem odd that they are all so low on voltage and not just a few?

Is my charger screwed up or is this normal for the PowerDrive3 charger? Is the charger destroying my batteries?

Based on what I'm reading, the charger and charging system is working fine. The light on the dash may have a bad bulb. That may be why you've never seen it illuminate. I'm thinking you definitely have an issue with the batteries. The numbers that your charger is putting out while charging are fine but your batteries settle to a low voltage after a resting period. 49.1 is very weak for a "fully charged" set of batteries. Those OEM batteries are not known for greatness. I've changed many of them out before they were 3 years old. I think if you get a good set of Trojan or Crown batteries you'll find that your problems will go away.

Thanks for the input. Any recommendation on where to get good deals on batteries? Would a brand new set of Powertron P8000 8v with a 12 month factory warranty for $538 (plus tax and my cores) be a good deal? Or should I shell out for the Trojans?

Here is another thing you can try. It's a equalization charge. Next time when your batteries are finished charging unplug the charger, wait a few seconds and plug it back in again. This will take the batteries to max voltage. It might help some.

that price on the Powertrons is about right around here , you can get the Trojan 875's for $675.00 ( that includes tax ) at J&J batteries in Statham ... they are probably about 30 to 40 miles from you depending on what part of Atlanta you live in.

Trojans can't be beat. The pricing fishbooz gave you is an incredible price for Trojans.
