I want to use AGM batteries to start my 8V92TA. I find battery comparisons tricky and not apples to apples. Does anyone know if the red optima batteries would work? It is rated:
MCA 1000 amps
CCA 800 amps
capacity 50ah (C/20)
reserve capacity BCI: 100 minutes (25amp discharge to 10.5 volts)
Thanks,
Ray
If you have a 12V starter, 3 will work well, if you have a 24v starter you'll have to use 4. Always look at the CCA since that is rated at 0 degrees F. In warm weather you could get by with two. I have two 950CCA size 31 Interstates that work well. But I also have a jumper solenoid that I can activate from the drivers seat to have my two Lifeline AGM 8D's help out. I have started the engine just on the AGM batteries when the starting batteries were dead one time. Suggest you also get the jumper solenoid-can use it to charge the deep cycle batteries while driving. Good Luck, TomC
