booster

Hi all, wanted to get some opinions and feedback on an issue with the layout of our ranch style house. It has two baths, which are on one end of the house, and a two car garage, which is on the other end the house. I haven't measured, but I would guess it's about 70 ft run or so from the water...

During my lifetime, I've gone through almost a dozen of these booster battery packs. None have lasted more than a few years before the internal lead acid battery fails. I've replaced a couple of these dead batteries but the cost is so close to buying a new pack that it doesn't seem worth it...
