Just a quick look at the Schumacher Battery Charger / Maintainer Model SP1286. It works for both 6v and 12v batteries and was rather inexpensive for an automatic charger. If you have tractors, mowers, tools, kids toys, etc.. that run on 6v or 12v batteries I would recommend you look into this item. It’s been a life saver for me and my kiddos Best Choice Products Jeep!
