Patented features – get back on the road within minutes.

Everyone knows how inconvenient a dead battery can be, but that frustration is a thing of the past with the BC20BDAU, the completely autonomous bench battery charger that takes all the guesswork out of charging any type of battery you may have. With Black & Decker’s patented 40 amp Engine Restart technology, this bench charger can start most dead vehicles within an amazing 90 seconds, whether it be an AGM, GEL or WET automotive or marine 12 volt battery.

Most Advanced Charger on the Market
The BC20BDAU boasts many patented features unique to Black & Decker such as an alternator and battery voltage check gauge which isview able from a large LCD monitoring screen. The LCD screen displays information through easy to understand icons, monitors the electrical charge of your alternator and battery simultaneously, and even alerts if the battery clamps are connected to the incorrect terminals.

Completely Worry-Free Charging
Because the BC20BDAU was created with you in mind, everything is completely automated for more ease of use. Many other chargers require that you set various settings such as battery type and size but with the BC20BDAU you can simply plug in the charger and walk away knowing that everything will be done correctly, and with the capability of charging 40% faster than most conventional chargers, you will be back on the road in no time.
