Review on Mroinge 6V / 12V 1A Fully Automatic Trickle Battery Charger/Maintainer For Automotive Vehicle Motorcycle Lawn Mower ATV RV Powersport Boat, Sealed Deep-Cycle AGM Gel Cell Lead Acid Batteries by Terrance Palau

Bought first one of these battery tenders approximately one and a half years ago for my Diesel farm tractor battery and it keeps the battery fully charged even with the extreme cold we had over last winter. She starts right up where before battery was a little sluggish and tractor harder to start. I bought a second one for my garden tractor battery and it keeps it charged up nicely.
