I looked into changing my battery load over to rechargeable batteries. The new Enloop's are awesome for durability and longevity. You might look into it. You can extend your stores elsewhere with a 800% recovery on investment with the Enloops. Look them up and see what you think. Leaves plenty of extra cash left over for other big investments.
I will check into these as I just looked at how much we dropped on disposable batts.
We had a power outage last Sunday night and it was a good opportunity for us to drill on these things. We did OK but we were short on Battery's. Had all the flash lites up and running but way short on spares. Also had the standard experience with the small 2 cycle genny. If it wants to run...it will. If no...oh well. It did not want to run. We cycle the genny's monthly and it was ran a few weeks ago but it is no different than our 2 cycle chain saws. Cantankerousness pieces at best. I put some starting fluid on the shelf. A good shot of that and it is off to the races.
The inverter back up ran OK so we are on track.
