I thought some of you might find this interesting.
Here are a few pictures from work.
The big square batteries are 3900 amp hour @ an 8 hour rate. The round cells are 1680Ah. String C was manufactured 03/1982. The key to battey longevity seems to be:
1. Starting with quality cells.
2. Shollow depth of discharge.
3. Temperature controll.
4. Maintenance.
I discharge test them every year. The large square cells put out just over 500 amps. The round cells put out an average of 180 amps per string. There are 5 strings total. The newest round cells are from 2007.
This plant is almost always in float at 52.80 volts. Never the typical 3 stage.
