Well thanks for the info. I have been thinking about getting a load tester as they can be bought at princess auto for about $25. They just don't do 6v so it seemed to defeat the purpose. I have tried a couple of digital multimeter's, but they did not seem able to determine enough consistency to be usefull. A hydrometer is an option.

I have not drained and refilled yet, I am just curious about the process. I am inquiring if anyone out there has personal experience with it.

Using only distilled water because of mineral deposits is somthing I am familiar with as my cigar humidors operate on the same principal.

Mixing mulitiple brands of unkown length was/is a gamble. They are all 6v as the 8d's are not attached to the house bank. They may have hit the wall and are time to be recycled. They seem to charge up, they just don't hold a full charge for too long. They drop down to 12.8 volts after a full charge after a day or so. The battery specialists (the suppliers @ the RV dealership I worked briefly at) had said that this was still a good resting charge for older 6v and were still usable. I can still get 4 - 5 days with out charging, so I am not tossing them yet. I am looking at ways to restore them.

I have never deep cycled them below 11.2 volts, is this a problem?

Thanks all!

-Richard

Hi Richard,

If the resting voltage of your battery bank is 12.8v you're right on the money for a fully charged battery; it doesn't get any better than that. The only way they should have a higher voltage is if they're being charged or just came off the charger.

50% discharged is about 12.1 volts and 10.5 volts is generally considered "dead". 11.2 volts is a pretty deep discharge but if they're true deep cycle batteries they should handle that but they do have a finite number of "cycles" they can go through.

It doesn't sound to me like you've really got a problem at all unless with a known light load (say at the 20-hour discharge rate) they die off too quickly or with a really heavy load they all but give up immediately. Otherwise it sounds like they're in fine shape.

look for a good hydrometer, the kind with the big bulb and not just 4 or 5 balls, a good hydrometer will also have a thermometer/(temp. compensated), then go get a plastic welding rod container to store it in. also flush it with clean h20 before storing it.

That's what I would think too. That's why I suggested a good true load test. All to often at work I see batteries that show plenty of resting voltage (not just a surface charge) but will fail as soon as we put even a 200 cca load on them.

I've also seen plenty of people try and make warranty claims because they can't get the voltage up to where they think it should be, but at 12.4 volts they might test out to 800 cca sustained for 15 seconds on a 500 cca battery.

So much science and so much black magic in this battery business.....

batteries

Well, thanks all. It's good to hear that I am overly concerned about my batteries and that they are in decent shape. I would prefer not to dump $600 worth of batteries is I can avoid it. After christmas I will look into diagnostic equipment.
