Break-in process on golf cart batteries

Postby stansroga on Fri Dec 04, 2009 12:18 pm

I have 6 new Excide golf cart batteries rated at 225ah hooked up in three banks of two. I am doing your Break-in procedure on 2 batteries at a time. I 've just completed the Break-in process on the first bank, as suggested by the Ample Power manal "living on 12 Volts", and I have several questions.

1. I did three charge/discharge cycles. On the first cycle the batteries were discharged to 10'5v after 177ah. By the third round we got 207ah. Is that as good as it gets or are the batteries defective? They are rated at 225ah.
2. During the "equilization" process the voltage got up to 15.85v at 5-10 amps for several hours using a 2000watt Xantac. The voltage seems way to high?
3. During the 3rd discharge cycle, although the batteries performed fairly well, they seemed to HEAT UP a lot during the first 5 (very approximate) hours of the discharge. This seemed strange being that I was only drawing off 11 amps? Note, I started the discharge immediately after the equilization was over.
4. After the 3rd discharge cycle was over the water level was almost down to the level of the plates, all cells equal. I added about a pint of water, using a Pro-Fill system to get the water back up. Is that water usage excessive?
