This has been one of the best products I have used. It works with the drill and the trim saw. I'm really happy that batteries are still available (and at a fair price).
I have a great old Black and Decker drill that I've bought a few years ago and the battery slowly faded. Quite a few manufacturers are now even selling their new cordless drills WITHOUT a battery - so you have to purchase the new drill and then buy a battery for it - which is just crazy. I bought this battery and it's like new again. Cordless drills are such a rip off these days; There's a huge variety of battery voltages and options - and for that reason I've always had corded drills in my tool arsenal because they're dependable and they are not subject to technological trendiness. Sometimes though it's just SO convenient to have the cordless to do a quick job and I loved being able to give new life to my old tool, which is familiar to me and works great. This was well worth the money.
I had been looking for replacement batteries and could not find them locally without placing a special order. I tried Amazon, and not only did they have the batteries, but at a much better price than I had been quoted. As a bonus they arrived next day. Great Job Amazon.
I didn't feel like driving all over to get an extra battery for my drill and this was a great way to get it quicker in my opinion. When it showed up, very nicely packed, I charged it and it has performed great. I will buy more accessories like this again from Amazon.
I'm not surprised that the batteries have faded, but I am shocked that the charger gave up the ghost. A sensible charger would not die even if asked to charge a dead short.Instead of being in the position of needing just two battery packs (a $60 problem), I now need two packs and a charger (a $100 problem). I have (had) two 14.4 PS140 batteries and the PS1514BU fast charger for my FireStorm drill. The charger failed with an open circuit in the primary of the transformer. Typical trickle charge rates are set to completely charge a battery in 10 hours. I took the charger apart (it uses T15 security screws), and discovered some surprising points. I do not have much faith in Black and Decker, and I suspect the charger is so poorly designed that it will kill itself trying to charge a battery pack with shorted cells.
I wouldn't trust a new Black and Decker charger because it might die down the road.Although some people have suggested using a DeWalt charger, there may be a problem with that solution. The charger and the batteries have died. The right approach appears be to chuck everything and get a new drill -- one with a more sensible charging system. There is no fuse or power limiting device. I also expected a more sophisticated charging circuit. The DeWalt battery packs have twice the ampere-hour capacity of the PS140, so they may use a higher trickle charge current. Charging batteries at too high a rate will cause the cells to vent and age more quickly.
