This battery will only last 1 hour at peak draw. Then it would need to be recharged. That's not happening in a blackout situation.

So you always have to think about minimizing the draw to make it last. Limp along.

A generator can go continuously at peak draw and in my case about 6 hours with the gas tank. And then you can refill it immediately and continue your max draw.

So this is really to ride out less than a couple of hours. If it goes more than that then oh well. When I first moved here there was a 24-hour blackout so I bought for that. Then it never happened again.
