EBay has two categories for automotive battery charges: Automotive Battery Chargers and Car Battery Chargers. The latter has subcategories for different types of automotive battery chargers.
The Automotive Battery Charger category on eBay mostly contains 12-volt battery chargers, while the Car Battery Charger category has a number of subcategories. Portable batteries are useful for recharging a car without having to connect it to another car's battery. Another option is solar car battery chargers, which are a great option for drivers who run electronic on their car's main battery. Jump-starting kits are useful for getting a car rolling without having to rely on another vehicle, which makes these battery kits useful for emergency situations.
