The Xantrex inverter/charger that came on the boat when we bought it went up in flames (literally - didn't catch anything else on fire, thankfully!), and has been replaced with a new Magnum Energy inverter/charger. In order to properly set it up, I need to enter data about the batteries, so it can charge them properly.
The batteries are eight (8) Duralast Heavy Duty GC2 6 volts - pairs wired together make it four (4) 12V pairs. The only spec I can find about these batteries is on the label: "Reserve Capacity 100 Min." But from some research, it seems that a lot of GC2 batteries have a MUCH higher Reserve Capacity - as much a 400 minutes - so I'm wondering if this 100 Minutes on the label is giving me meaningful information (maybe it's at a different Amp draw than normal, or something).
I've sent emails to AutoZone (the retailer) and Johnson Controls (the manufacturer, I believe), but no response.
Does anyone have any suggestions for how I can determine the Amp Hours rating of these batteries? Is there some kind of test I can perform myself on one of them, to get at least some kind of ballpark rating? Thanks in advance for any help you can offer.
