FlyWright: You have 6 six volt golf cart batts at 660 amp hours, so is that 110 amp hours per batt? If so, from what I've read here and guessing, you hooked them up in series to get the 12 volts. My understanding is that when this is done (series) you double the voltage (6v to 12v) but the amp hours remain the same, 110 amp hours.
I just replaced 2 golf cart batts, 6v to 12v in series, 105 amp hours each, and I still only have 105 amp hours though it's now 12v. That's the way I read things anyway.

GC, I have 6 golf cart batteries that are each 6V and 220AH. Put 2 together in series and I get 12V and 220AH. Take 3 of those series-pairs and hook them in parallel and I get 12V and 660AH.

When a pair of these batteries are connected in series, the voltage doubles and the AH remains the same. When a pair of these batteries are connected in parallel, the voltage remains the same and the AH doubles.

Most GC batteries I've encountered are around 200-230AH. I'm sure there are some higher and lower, I just have not encountered them. Are you sure your batts are 105AH? If they're Trojan T-105 batteries, they're rated at 225AH capacity at the 20-hour rate.

Where do you get the short cables to connect the batteries? Do you have them made?

FW: Ok, thanks for the explanation. I just bought 2 Pacer gc batts, made by Trojan, and they are 105ah at 20hr rate, I'll check that rating next time at the boat to be sure. Also installed the Pro-Fil batt watering system, sure makes that PIA job a lot easier.

Probably too long a story with rough language for this thread. Needless to say I am pixxed.

I'll send you a PM.

Come on Moon, tell the story. I ruined on of my batts when I dropped a wrench across the pos-neg poles on the batt, hell of a spark and gouged a pretty good nick on the wrench.

It might be that they are a 105 minute capacity at 75A as shown in the specs linked above. The 20-hr AH rating on that battery is 210AH. Of course, that might not be the same as your Pacer.

Thanks FW, that's it. My amp hours just doubled, in my brain only. Paid $94.60 per each including tax and trade in of old batts.

Don't ask me why I had to buy them.
OK, Don... I simply can't help my inquisitive nature - So - Why did you feel you had to buy those batts?

I'm so confused!!! Too busy to carefully read all posts.

Trying to keep up with this thread via occasional glances must resemble getting hit by a stun-gun (I've never had that charming experience... although on a construction site a 220 momentary short zapped me one time and I was luckily thrown back on my ass... dazed and confused).

Too much electricity being thrown loosely thrown around here - LOL

OK guys here it is. I did not want to take over this thread. Maybe this will put it to bed.

Battery Saga
Hey BlueYonder,

Here it is. I live an 11 hour drive from my boat. Because of obligations at home, I may be away from the boat for fairly long periods.

I hired a crew of "ladies" to detail the boat. I never leave the air conditioners running. When I got to the boat time before last the air conditioning cooling water pump was running. Well, the "lady" came by for money, and I asked about the A/C being on. She said that it was only on for a couple of days. I showed her moss growing under the outlet. That had never happened before,. They weren't through. So, I told her to stay out of the electrical box, and turn no switches.

When I got back to the boat last time, several switches had been turn on, and the battery charger had been turned off. The house bank consisting of 2 LifeLine AGM 8d batteries was completely flat. Absolutely no register on any meter. I tried several days to do a reconditioning charge, but they would only accept about a 60% charge. Even with lite loading they would be down to 50% in about an hour. They were trashed.

We had planned a 10 day cruise down to Biscayne Bay and the upper Keys. I had to order the batteries, put flag terminals on them. By that time it was too late to go.

I fired the "ladies", and changed the lock on the boat. What a disaster.

Don
