Buying Guide Questions

While there are notable things about the battery maintainer, there are also questions about its use.

How Does Black + Decker BM3B Battery Charger Work?

Battery Chargers are relatively easy to handle, as long as you have them in great working condition. A Black + Decker BM3B Battery Charger, for instance, has 3 connector sets – DC accessory plug, cable clamps, and O-ring terminals. All you have to do is connect the cable clamps to the battery and let the mounting bracket hold it in position. Next, set a voltage to charge your battery and watch as the Green LED shows the status. When the battery is full, it automatically switches into float mode.

What is the Difference between a Battery Charger and a Battery Maintainer?

The only difference between Battery Chargers and Battery Maintainers is in their response after the battery is full. A battery charger applies constant charge until the battery is full in which must be removed immediately after; a battery maintainer, on the other hand, automatically stops charging.

Conclusion
