The Battery Tender Plus car battery charger is one of the best chargers we found and which makes it first on our list. It is a product of Deltran, and it is a compact charger ideal for owners of rarely driven cars such as golf carts, classic show cars, and ATVs. Though it may not boast of a lot of power as most of the top battery boosters, it has a remarkable ability to slowly charge and maintain a 12V and 6V batteries with a lot of ease.
The charger comes fitted with a microprocessor unit to help assess the state of the battery, and it will commence charging in the correct mode automatically. The microprocessor will also ensure the battery is not overcharged by hooking off automatically when the battery is fully charged.
The Battery Tender Plus charger also comes with lovely safety features to ensure maximum safety every time it is in use. These include reverse-polarity protection and the spark proof clamps. With the reverse polarity protection, the battery won’t charge if it detects that the clamps have been placed on the wrong terminals as this usually ends up ruining the battery because it can result in overheating or even an explosion.
