House batteries to use with large inverter
We're planning some camping where generator use is restricted, so I want to make sure my batteries will hold up between charges. We'll usually draw less than 25 amps, but I'd like the option of runni...

The Trojan golf cart battery is rated at 75 amp draw. That is a lot of power to put on a battery for a long time, such as cooking for 8 minutes. Even most drives that I do in the golf carts at my work involve picking up speed to 13 MPH, and then running part throttle, until there might be a hill. Uphill can draw max amps for a few seconds (20 seconds and you are at the top of the hill where I work), but downhill can actually charge the battery. Most drives are less than 1/2 mile, or about 2 minutes. (at 15 MPH you would drive it would take 4 minutes to drive 1 mile).
SO the Trojan T-105 that we use will last about 105 minutes at 75 amps draw before reaching 5.0 volts.
I would recommend a set of T-125 batteries, same size as the T-105, but a little more lead, and thus can hold about 20% more power. I have 4 T-105's. I used my microwave on my Trace M1512 inverter/charger, and it no longer cooks nearly as quickly, so it had to be replaced. Now I just run the generator while microwaving, or bake it in the propane oven.
I also have a 415 watt solar system to recharge the batteries. This keeps them nearly full all day long. It will help a lot when cooking at night. But like I said, I would rather bake it or cook on the propane stove.
I hate listening to my generator!
Good luck,
Fred.
