Re: Battery capacity

OK...the 24 hour waiting is new to me. I do let the batteries set over
night before after a recharge. But that puts it well under the 24
hours of rest you mention.

The wire size is between 6-8 ga in the circuit from the battery to the
inverter. I don't remember the exact ga I purchased and it is not
mentioned on the wire. But I did check a wire size chart that
considered the distance between the battery and inverter before I
decided on the wire size. In this area I tried to exceed the minimum
specs provide for on the chart I was using.. The distance is about 5
feet.

For the connection of the wire to the battery, I wrapped the wire
around the battery terminal to ensure a snug fit, I then soldered the
wire keeping the fit to ensure all the strands were together. When I
attached the soldered end to the battery that end was flatten to get
the most connection I could. Not very quantitative, I realize.

The present recondition cycle will end around 9:00 this evening. After
that I will let the batteries rest for 24 hours as you suggest before I
attempt further testing. I do have plenty of time on this before the
batteries are out of warranty which is in another 6 months.

Your questions have been very helpful to me in thinking through this
problem.

Have I missed anything?

I start the charging rate at 20 amps and it seems to settle in for an

an hour and fifteen minutes recharging for each hour of discharge.

That's about right for a first approximation, it's acting like a
battery should. Now you need to confirm that all the connections
between your batteries, and between the batttery and inverter, are
large wires, properly crimped into substantial ring terminals, and
firmly bolted down to the posts on the batteries.

Then you can start doing calibrated discharge profiles, letting the
batteries sit for 24 hours, and measuring their open circuit voltage.

Also, make sure you top your batteries off with distilled water
_after_ charging them, and do another equalizing cycle and
discharge/charge cycle before measuring the specific gravity.
