Pad, pencil, voltmeter. Charge batt fully. Put on load, no charger. Measure voltage every 15 minutes until either the voltage is below you minimum setting or 3 hours elapse. Plot the voltage. You can extend the line until you hit the min voltage point and you will know how long you can run.
If you k now the current, multiply current by run to get amp hours. Compare with original spec of the battery. While sitting around during the test, also measure and record individual cell voltage. They should all drop about the same. If one or more drops significantly more than the others those are bad cells and need to be replaced. I use the BC2000 on my Eltek/valere charger. It does all of this automatically.
