To use the Black & Decker 4/10/20/40 Amp 12 Volt Smart Battery Charger, follow these steps:
If your Black & Decker charger is not charging the battery, it could be due to a bad battery connection or the battery voltage being too low to accept a charge. You should:
To use the 110 amp engine start feature:
The battery recondition function is an automatic mode that, once started, continues for 24 hours and then stops. It works by sending a series of electrical pulses to break the crystalline form of lead sulfate, which builds up on battery plates when a lead-acid battery discharges. This process helps return these chemicals into useful battery electrolytes, which can restore a sulfated battery's ability to hold a full charge. Periodic reconditioning is recommended to maintain a battery's optimum performance.
If there are no lights displaying on your Black & Decker battery charger, you should:
The different amperage settings (4, 10, 20, 40 Amp) are controlled by the Charge Rate Selector button. This allows the user to select the charger rate based on battery size. The selection and the actual battery charge rate are monitored by the microprocessor, and the charger will stop charging if the rate is too fast or too slow for the battery size or condition.
The Black & Decker 4/10/20/40 Amp 12 Volt Smart Battery Charger is designed for charging only 12 volt lead-acid batteries. This includes:
The smart technology in this Black & Decker charger prevents overcharging through its 3-stage high-efficiency charging technology and built-in microprocessor control, which ensures safe and complete charging. As the battery nears full charge capacity, the unit's output will automatically drop to a lower charge rate. When the battery is fully charged, the charger displays "FUL" and the charging complete LED is lit, accompanied by an "OFF BEEP", indicating the charging process has concluded.
Yes, the Black & Decker 4/10/20/40 Amp charger is fully automatic. It features 3-stage high-efficiency charging technology built-in microprocessor control that ensures fast, safe, and complete charging. The charger will automatically signal a "beep" and move into Stage 2 of the charging process when the battery reaches a maximum safe predetermined voltage. Additionally, as the battery nears full charge capacity, the unit's output will automatically drop to a lower charge rate.
