I recently found a Black & Decker 20v MAX cordless drill laying on the street. It had a few scuffs on it and the battery was a couple of feet away so it must have fallen off of someone's vehicle. Although the battery is holding its charge nicely, we all know they eventually run down and need to be recharged, so I needed to find a charger. The most cost effective solution turned out to be this battery and charger combo. The charger is very compact and will charge the battery in three to four hours, depending on how far it is discharged, and has the requisite protective circuitry to prevent overcharging. Using the same technology as batteries for laptops and cell phones, the lithium ion battery pack itself is compact and relatively lightweight compared to the bulky nickel cadmium battery packs my older 18v cordless drill uses and it also lasts longer. And unlike NiCad batteries, lithium ion batteries don't develop a 'memory effect' if subjected to repeated shallow charges, that is, recharging before it's completely depleted; in fact, the instruction booklet recommends putting the battery on the charger after each use and keeping it there until the next time you need it. That way, you always start out with a fully charged battery, thus minimizing the frustration of running out of juice halfway through a project. And with the second battery that came with this charger, I can now run one down, swap in the other one and keep going while the first one charges.Read full review

On the bright side, it works with the tool I bought it for (Black & Decker string trimmer) and charges with the original charger. It was also wayyy cheaper than getting an original battery, and I was still able to finish my entire yard. With my single battery I had to choose whether my front yard or back was the one to get done today. My only complaint is the single-charge life of this battery. My original battery is 1500 mAh and lasts about 20-25 minutes; this 3.0Ah (3000 mAh, so "double" the life) only lasted about 35 minutes. Given that this is a cheap knockoff of the original Black & Decker battery, I'd say I got what I paid for and expected. It wasn't a waste of money, but if you want a truly long-lasting battery, you may want to go with the name brand.

Really does a nice job. Charges in less than a couple of hours and has tons of power. I use if for my Black and Decker Drill/Shears Combo and its great. Easy to use and you don't need to let the battery run low before you top off the battery. Also, it holds the charger for months! Highly recommended !

This was ordered a a second battery due to the relatively short life of the first battery when using the weed eater. Keeping this on standby, this battery is easy to swap in on the go and keep trimming around the yard without waiting several hours for the initial battery to recharge. Highly recommended!

They actually sent me the 5.0 AH batteries and they have great life. This was the first time ever that I could weed wack my 1/3 acre yard on a single battery. Improved power and life from all of my tools!
