BLACK+DECKER BC25BD Fully Automatic 25 Amp 12V Bench Battery Charger/Maintainer with 75A Engine Start, Alternator Check, Cable Clamps for Lead Acid Batteries

I already purchased the lesser amp version and it works flawlessly, finding the need for another variable charger. I bought this one which has a 75 amp jump start, a bit more power couldn't hurt right. So lets start. Attach to the battery and hit charge it reads the battery and then slowly begins to charge adding amps over a few seconds until it is at full power then showing the % of charge. Give it some time come back and when at 100% it automatically goes into "FLOAT" keeping the battery at 100% Very happy with this, if you need a charger this is the way to go.

Bought this for my husband as a gift. We didn’t need to use it until recently and just found the unit is defective and doesn’t work. Doesn’t even turn on! Such a waste of money. Update: Changed to 5 stars. I contacted the company and they were excellent. They replaced the faulty unit and now I have no issues. Great customer service and very efficient with taking care of issues

I purchased the BC25BD (25 amp version) of this product on July 3 2019. It is now August 10 2019. I've attempted to use it to charge 3 different batteries (2 automotive, 1 ATV) and it exhibits the exact same behavior every time. When you first attach the clamps to the positive and negative terminals on the battery, it will not display the existing charge on the battery even though the LCD lights up. Press the charge button and the battery charger's fan will begin running. The LCD will show that it is using a varying degree of amperage (depending on battery) and display that it is charging the battery; it will run for about 2 to 5 minutes; then, it will stop charging and display a warning symbol that something is wrong with the battery (not FLO, just warning/caution symbol ). I have attempted using normal charging and battery reconditioning (thinking that something was wrong with the battery the first time I saw this issue, i let it recondition for 24 hours.) My advice? Do not buy this from Black & Decker. Prior to this experience I thought B&D was a respectable name. After looking at some of the other 1 star reviews I can see that this issue is not unique to me. I won't be buying B&D products anymore. Update to this review: I bought a Schumacher SC1308 and it worked great. The three batteries I mentioned in this review are still going strong today because the Schumacher was able to de-sulfate them and charge them. They cost the same so I would advise just getting the Schumacher. Compare the 5 star and 1 star review count on that product and this one and you'll see why.

This charger does what it should. You plug it into the wall, hook up your alligator clips, and hit the button. A little while later, depending on just how discharged your battery is, it finishes and goes into float mode, having charged the battery to 13-some volts. It's simple, capable, fast enough for home use, and also offers a start assist function that I haven't needed to use. It also has a reconditioning mode that claims to break up deposits and get you some more battery life. I haven't tried that yet, and it would be very difficult to prove or disprove that it does anything. What I can say is, it recharged a couple assumed-dead (4 or 5 v) batteries for me and got me out of needing to buy two new batteries, so this charger has paid for itself approximately three times now.

The BC25BD works very well and is easy to use. I've already used it to charge and recondition battery in two cars. The display shows battery charge progress and shuts off automatically when charge is complete. Its engineering is well thought out and is designed so that it will not overcharge a battery. I like its ease of use, easy to read screen and overall construction of the product. Electrical plug has a storage area and battery connectors connect to the each side of the charger unit for storage. The only issue I had with this charger is that the Recondition Battery button was installed upside down. Somebody at B&D Q/C missed looking at the face of the product before it was boxed. I have rated the product 4-stars because Q/C missed an upside down button on the face of the unit. This cosmetic defect does not affect the operation of the charger, but it was annoying to receive a product that was not assembled correctly and this small visual defect leaves me thinking that Q/C may not be as observant as they should be during their control checks.

awesome service and shipping and the product works, it charged my battery so well now my car can go on.....

I have never owned a battery charger before. But this winter my truck started to give me fits with the battery getting low when the temperatures remained in the single digits overnight for several nights. So, I looked online and bought this product. I was very happy with the results. I first used it to give a "fast charge" to my battery so that I could start the truck. It counted down 90 seconds on the "fast charge" and then I was able to start the truck. Then I left the charger on to give a "trickle" charge to the battery and let it run for a couple of hours. It did a great job of charging the battery fully. I haven't had any trouble since with my battery. I have now used this on my truck as well as a friends car and we are both happy with the results.The main charge is a 25amp charge and the fast charge is 75amps. There are chargers out there with a larger amp charge, but I don't know why I would need anything more than this. I am completely satisfied.

This is my second charger like this. This time I moved up to the 75 amp booster. One word of praise and one of warning. The owners manual says first thing to do before connecting charger to battery is plug in the charger. First thing to do before disconnecting charger from battery is unplug charger. Not doing this is how I fried my last one that I had for 15 year. I had the polarity backward one time. The charger has circuitry to protect it from polarity reversal but only when it is plugged in. Thats the warning. The recondition feature, which I have used, got me two extra years out of a 5 year battery. I highly recommend it. I use the charge feature on all of my sealed mower batteries also. I do not think the recondition feature is for them, only conventional lead acid batteries. The one thing I learned with this charger, rereading the manual, batteries being serviced must have at least 2 volts for the charger to function. No totally dead batteries.

Great quality and works well and fast charging for my boat battery, gave 4 as it only comes with 110v power and we use 220v so had to buy a power converter

Had a Cat with similar specs prior and in my opinion this is a better charger. I have used the desulfate feature successfully to restore a couple of weak and seldom used car batteries, they are working for me again at -30C. The charging pattern changes with the state of charge and seems to top up batteries very well. I like the monitor as well as the cables. The booster does work but is sized for a light car or truck, too small for heavy equipment. At twenty amps there is not a long wait to bring up very large batteries any way. As with all smart chargers it will not charge a stone dead battery but this one will apply a boost which may kick it into a high enough level to start a charge in the case of a total drain such as leaving lights on overnight. Otherwise you need an old style transformer type to bring a stone dead battery into a chargeable state, then this one will safely fully charge anything I have put to it. As with any charger ensure your batteries have proper electrolyte level and are not frozen prior to attempting a charge.

Entrega rápida y producto en buen estado, en su primer uso resultó excelente hasta el momento no he visto o notado algún defecto en el producto, muchas gracias

Nothing to dislike, except that you can't set the charge rate. It will "read the battery" and determine the optimal charging rate. An adjustable max charge rate would have been nice, as I'd prefer not to have to trust my battery to it's digital brain. But, that being said, it wasn't a deal breaker. As others have noted, it won't "see" a battery with less than 3 or so volts. If a battery is that flat, just toss a set of jumper cables on it from a good battery to bring the voltage level up to a level that will work. It's not "seeing" the completely flat battery is just proof that it's tiny digital brain is protecting the charger and the battery from potential harm. For the price, you can't go wrong!

El producto que ordené no funcionaba, lo conectabas a la pared y no prendía el led, no hacía nada... tuve que devolverlo.
