We tested our batteries this year as follows:
1. Acquire battery
2. Plug battery into dc to ac converter
3. Attach volt meter to leads
4. Plug Halogen bulb into converter
5. Turn on converter
6. Turn on bulb
7. Record Battery start voltage
8. Wait for battery to drop below 10 volts
9. Record time taken
10. Label battery accordingly
It took awhile, but worked fairly well for reheating pizza.
