Whether it's for juicing up a drained car battery or keeping one alive through the long, cold winter months, car battery chargers are a standard accessory in any car owner's garage. And if you are looking for a battery charger right now, you'll likely to be inundated with so many models that offer performance, portability, or a combination of both. And when it comes to the latter, one brand that is trying to make waves is Battery Doctor. A well-known brand for battery-related parts and accessories, Battery Doctor offers a line of compact car battery chargers that provide adequate good performance and are easy to transport.
For this review, we tested one of the more popular models of the Battery Doctor battery charger - the Battery Doc Sport Charger - to see whether it could provide an electrifying performance or shorted out by the competition.

- The charger is light and very compact. One of the first things we noticed with the Battery Doctor Sport charger is its weight. At 6 ounces, this charger is one of the lightest models we have encountered. It certainly won't be a hassle carrying this device around and can be easily stowed in the trunk or even in the glove compartment.
- Can be used on most car or vehicle batteries. Whether it's a typical wet cell or a high end AGM battery, we found this charger to work with virtually almost any modern lead-acid battery we could find.
- Charges very slowly. The Battery Doctor charger's size does come at a cost of slower charging performance. It's basically a trickle charger; we had to charge a nearly-empty battery through the night up until late morning just to get it to 100%.
The bottom line
The sport battery charger is a handy way to charge your car's battery, but it is quite inadequate in terms of charging performance compared to commercial battery charger. We advise using these chargers mainly to maintain batteries that are not in use.
