Fully Automatic Charging
The Smart Battery Charger is fully automatic and electronic, with a Digital Smart microprocessor control and an LED indicator for selecting your charging rate. The three stage automatic rapid charging operates at 40 amps, 20 amps, 10 amps, and 4 amps, with an average 5 minute engine start time and 4.5 hour full battery charge.
The Smart Battery Charger features 3-stage recharging technology. View larger.
This device also features a reverse hook-up warning alarm.
The LED display lets you know when the battery is fully charged.
It uses a 3-stage automatic high-frequency charging technology to build the battery back up to its normal output level, making it more efficient at charging than conventional model chargers.
Built-in Safety Precautions
The Smart Battery Charger also has a spark-resistant reverse hook-up and overcharge protection circuit built into it to insure that the clamps are not accidentally affixed to the opposite terminals, which would damage the battery. The automatic float mode monitoring tells the unit when the battery is ready to avoid overcharging.
Black & Decker offers a full 2-year warranty.
