Automatic Battery Float Charger
http://www.harborfreight.com/cpi/cta...emnumber=42292
I picked up one of these for my truck from Harbor Freight. I dont drive it but once every two months or so and needed something to keep a good charge on the battery. Works great. Every time I go to start my truck up it has great cranking power. And for 10 bucks ( you can usually get them on sale for around 7) they pay for themselves in no time because I dont have to run my truck every week to insure the battery is charged.
I liked it so much I picked on up for my Cub, and I thought I would tell you guys about them.
