Black & Decker charger conversion

Instead of buying this charger, consider purchasing a 36 volt charger for one of the small razor type scooters or electric dirt bikes.  they can be found for under $15.  Create a conversion connector for the battery for about $2 and you are good to go.  This is an overpriced charger.

A great battery charger for Black and Decker appliances.  My weed wacker, blower, and hedge trimmer were regularly running out in about 25 minutes on a 20V battery, which was fine so long as I had a spare.  But once the two batteries were gone, it took about 6 hours to charge them up on the regular recharger.  This device cut that to about 30 minutes, a huge boost to productivity in the yard.

All current cell phone chargers, razors have built in converters.  As this is for small wattage conversion I found it useless and a mistake to purchase.

Have a Black and Decker 36V lawn mower.  B&D apparently decided I shouldn't use it any more so discontinued their grossly overpriced charger.  I bought this charger, along with a proper receptical, wired it in and it works great.  Better than original in all ways.  Good product, good price.

Very good replacement alternative. The charger did exactly what I wanted. Would recommend this charger.

Not impressed with the charger or the 18650 battery. This will be a backup for my D2 Digicharger. The 18650 battery that came with the charger will be a backup for my backups. I haven't tested the battery yet but my guess is that its not making 2200 mah. Oh well.

This unit worked as expected. I had installed the volt/ammeter in place of the analog ammeter in a Schumacher model SE-1010-2 battery charger. After gutting out the old ammeter and a little judicious use of a flat file, I was able to insert the display case into the ammeter housing. Since this charger only puts out 10-15 amps max, I removed the 8mm connector bolts from the ammeter shunt bar and used the 2 smaller screws to make the electrical connections after gluing the shunt to a block of wood and glued the assembly to the charger case front.

The connection diagrams that come with the unit are quite usable and clear (Of course I've been an electronics technician for over 45 years). There are adjustments on the display to set the voltage and current being displayed, but I found the readings to be fairly close to the measurements I made with my test equipment... Your mileage may vary.

I bought one of these kits because my two older 19.2v Ni-cad batts refused to charge in the 1-hour charger.

I bought a used kit because I really only wanted the Li-ion battery and dual-mode charger (charges both Ni-cad and Li-ion batts). The price I paid for the used kit was less than the price for a new Li-ion batt.

Just for fun I put a 'dead' Ni-cad battery on the new charger and it began to charge. After a few minutes I moved it over to the 1-hour charger and it fully charged!!! The new charger (model CH-2021) may also revive some of your old 19.2v. Ni-cads.

What a deal. I recommend getting the used kit from Back Alley Discount if they have any more.

Charger is not the right one for the batteries received.

Excellent adaptor. I use it to charge my british toothbrush and dewalt batteries. Nice that you csn change input voltage with a jumper from 110v 200v 220v and 240v. 4 times cheaper than here in Trinidad and Tobago ehich is where in using it (110v).

Overpriced battery without a charger. Come to find out, the charger costs just as much. Won't be buying anything Black & Decker again.

I had ordered the replacement charger for Black and Decker compact saw LPS7000 with its P/N  90547272.
 The actual item that I got it: P/N  90593304

No instructions included. I'm trying to insert the spare battery in the charger just like the picture but so far no luck in getting them to actually charge. Not sure if the chargers are both DOA or if i'm not aligning the two small pins in the correct four slots of the battery. Small switch near the charging port but no idea what it does other than turn the led different colors. Online page of basic instructions would have been really nice.

I too am one of those whose included chargers on his Black and Decker cordless tools decided to fry themselves, taking two batteries with them in the process. Fortunately Amazon had not only replacement batteries, but replacement chargers as well. Thanks to the reviews, I knew to stay away from the crummy factory charger and get this one instead.

I was hoping this charger could save my original batteries but sadly they were too far gone. But this charger works great with the replacements I also ordered from Amazon, along with some no-name replacement I ordered from eBay a couple of years back.

As previously mentioned, I would like a more informative way to advise me of the charging status, rather than just a single red light. For example, red for a battery that is bad, yellow for charging, green for fully charged.

Works very good, this replaced an older Black & Decker .It is a little noisy compared to the old one.

Bought 14.4V 4.0Ah NiMH 2 pack, and an 18V 3Ah NiMH 2 pack from Powerextra.
I haven't used them yet, but the build quality is same/better than B&D, the packaging is better than B&D, stated capacity is higher than B&D NiCD, and they say that they are compatible with my current B&D chargers.  They came with a nice set of gloves and an AC socket tester (not sure why, but it works nicely); all at a price MUCH better than B&D.  Powerextra is definitely the way to go!

I will update if when I use them they turn out to have any issues, but if un-updated, one can assume that they worked great!

Although my model HP 722 was not listed as one of the drills that are compatible with this power pack, I took a chance and ordered it.  I am happy so say that it works great with my drill.  Since Ryobi no longer makes these battery packs, I was pleased to find this one on Amazon.  Some posters have noted that the original charger will not plug to this pack, but that's an easy fix if you know how to use a soldering iron. Simply go to an electronic parts store and buy a 3.0 mm ID/5.5 mm OD coaxial plug, cut off the old one and solder on the new one.  Center pin is positive. If the original charger is also needed for other tools, you could make an adapter by getting a socket which fits the charger and wiring it back-to-back with the plug for the new power pack.
