Review on Husqvarna BC 0.8 Battery Charger / Maintainer: Efficient Charging and Maintenance for Long-lasting Performance by Scot Hughes

With this unit you don't have to worry about keeping the tractor battery charged in winter. The instructions are simple and easy to follow. If you check the indicators at the top of the device, you'll know where it is in the order. And with a Husqvarna tractor, there's a simple plug-in that lets you connect the device to your tractor and keep your hands clean. Haven't tried anything else but it's supposed to detect the required battery voltage and polarity so if you can find the battery posts the connections can't be wrong.
