I am not happy with the performance and lifetime we are getting out of our batteries and I want to purchase or build appropriate equipment to improve if possible. >> Funny you should ask, as I will have an article on a device that hooks to your winch batteries and you forget it, it stays hooked up while you charge with your existing charger and it litterally renews your batterys. The technology is not new and it is not gimmick. It's being used in critical lead acid systems all over the world today AND its not expensive. The device I am talking about is solar powered or can be plugged in. It is not a charger but it does knock off the sulfation that collects starting the day the battery is energized. It will turn sour batteries into fresh ones. The version for us is the Solargizer. With it you can do any charging ritual that might make you happy, but you will be doing it to all of the plate surface you originally bought. Where?
