Black & Decker BM3B Battery Charger and Maintainer
Say goodbye to dead vehicle batteries!
Nothing is more maddening than a dead vehicle battery. And it usually happens when you need it least. To solve this problem, Black & Decker has the answer with their 1.5 amp high frequency battery charger / maintainer.
What is a high frequency battery charger / maintainer you ask? It’s simple. ..if you have a vehicle battery and do not know how long to charge it up, or what type of battery it is, or whether you can leave it connected all season long. ..then this is the battery charger / maintainer for you. The Black & Decker Charger / Maintainer takes all the guesswork out of charging and maintaining your battery, no matter what season it is.
Whether you have a car, truck, boat, motorcycle, RV, lawn tractor, or any other vehicle with a 6 or 12-volt battery, simply hook the Black & Decker charger / maintainer up to the battery (you have three choices on how to do this), choose the 6 or 12-volt option, plug it in and walk away. It does all the thinking for you. It’s the perfect choice when the last thing you want to think about is your battery.
- 1.5 amp charger / maintainer
- For 6 or 12 volt batteries
- Sealed for protection against moisture, dust and oil
- Mounting brackets
- I year limited warranty
One of three ways to connect to your battery for charging or maintaining.
Great way to connect to your battery if you are charging it for an extended period of time, like during the off season.
If you prefer to charge / maintain your battery from inside your vehicle this is a great option. Simply use the DC plug with your vehicle’s accessory outlet. No touching your battery means your hands stay clean!
Select the mode in which you will connect to your battery by using the quick connect attachments with the charger / maintainer.
First connect the clamps or O-rings to your battery. You may also charge your battery by using the DC plug with your vehicle’s accessory (cigarette lighter) outlet.
You may also choose to charge your vehicle’s battery outside of the vehicle. This is a good option if you are charging a boat battery or a battery that is being maintained during the off season.
Once you have chosen your method to connect to your battery, slide the switch to either 6 or 12-volt depending on your battery, plug it in and walk away! It’s that simple.

The switch to select 6 or 12V is weak and easily moved by accident.
The Schumacher SEM-1562A-CA (also sold by Amazon) is the same price, automatically senses whether it's charging a 6 or 12V battery (no switch) and has indicators that are easier to read and give more information. It also claims to have a desulfation mode. I purchased the Schumacher at about the same time and it has been working without fault.
I would not purcahse this product again. Depending on cost and resistance encountered, the thing may get returned or trashed.
Update 3/25 - Two months after calling on the phone, getting an authorization and sending in the dead unit for a warranty replacement, nothing has arrived. Not only is the product defective, but it seems the company is as well. I will avoid their brand and their holding company and all of its brands as much as possible.
I''ve downgraded this item to 1 star as the charger does not perform as intended. I kept it on a motorcycle battery all winter and came back to find the battery is completely dead although the maintainer light was still showing green. I am also thinking this may have possibly been overcharging the battery as I could see acid slightly trickling from the sides of the fill caps.
FYI: Take the warranty info with a grain of salt, it's been 4 months since I've purchased so Amazon wont take it back and Black and Decker customer service has been nothing short of terrible, almost condescending on the phone and refusing to help me exchange for a new one. No I would not buy again nor any Black and Decker product- my advice would be to spend a few extra dollars and get a quality charger.
Not much to say about the actual charger - there's only one button for 6v/12v operation. Green steady light = charged. Red = it's on backwards or some kind of internal damage. It works. That's all it needs to do.
Expecting snow so I roamed out the 4 wheel drive vehicle (Dodge Durango) with the BM3B attached with clamps. The minder had a solid red light. This indicates a reversed polarity. It was not. Thought, bleh, the vehicle was run just a week ago so I am sure it is still charged. Nope. The battery is now completely dead. Unhooked the minder and inspected all of the plugs. Hooked it back up and had a solid green light. Waited for three to four minutes and it went back to a solid red again.
Went to my second 4 wheel drive vehicle (Land Rover) and hooked it up just to see. Solid green light. Waited three to four minutes and the solid red light appeared again. Since it worked for a few minutes it really gives the impression it will continue working. Who has the time to check on it just to make sure it is still alive? It seems like this may just be a hit or miss deal where it works or doesn't. Don't really care to go through the effort of sending it back based on the troubles from others have reported. This is probably the only time it would have really mattered (snow once every few years).
Since there is no return and support from B&D for these devices and since I’m a electronic engineer, decided to open it to see if is any fuse or visible damage in the circuit. The fuse, the AC to DC converter and the switching section was delivering 13Vdc before the output relay. Same as the LED's, the relay never turns on. All semiconductors okay, but seams that the micro controller its defective.
The point is that the circuit board was dirty with finger prints and some solder areas like if ones were repaired. No quality control at all, cheap components, that it’s no to be surprised buying a cheep device, even if it’s B&D. Maybe I was unlucky with this one and for other it works, but beware on B&D cheap equipment's. Go for something more pro.
