Review on [2-Pack] LEICESTERCN 12V Battery Trickle Charger Maintainer - Portable Smart Float Charger for Car, Motorcycle, Lawn Mower - SLA, AGM, Gel, Wet, Lead Acid Batteries by Michael Hughes

Was much better than I expected for the price. I installed permanent battery connectors that make plugging and unplugging easier. The single-ended connection means you can be confident that everyone will connect the batteries without accidentally reversing polarity. For example, the added security of a built-in fuse fitted to the battery's permanent connection. I ended up buying 2 more for my garden tractor and motorcycle.
