I have a Black and Decker 18v string trimmer. It came with two batteries. I paid $80 for it 3 or 4 years ago.

One has gone bad. The other is probably not far behind.

I can get two batteries from Amazon for $59.

Then I look on Lowes website, I can buy a new trimmer with one battery for $59 LOL.

I guess I'll try to figure out how to recell it myself.

Aloha, Dave:
Don't buy those cheap after marking batteries from Amazon. I made that mistake when I purchase cheap batteries for Amazon for DeWalt tools. I bought about five of them because they were almost half the price when compared with OEM batteries. They died one after another in less than six months.:-(

My experience with do-it-yourself cordless tool battery recelling has been disappointing. All the ones I've looked at have glued cases, which presents a challenge right off the bat: getting it open without destroying the case or disturbing the dimensions so much that it won't fit in the tool. The clearances are often pretty tight. If you do get the case thing figured out, you then have to deal with the complex cell arrangements dictated by the case shape and size.

I haven't found a satisfactory answer. And I have a couple of Makita tools that are about to run out of batteries, so I need to figure out the best way to deal with this.

I also have a circa 1995 Dewalt cordless hammerdrill for which batteries are no longer made, but I've pretty much give up on ever being able to use that again.

The case is screwed together but the cells are sort of glued? to a cardboard backed sheet on either side. It doesn't look easy to recell.

Slight tangent here...
I buy AA and 9v duracell batteries in the 40 packs. Usually at costco. Lately, these things have faded like yesterday's news. I can remember getting a week or more out of my data collector with fresh batteries. Now it's more like a day and a half.

The Amazon replacements are the actual B&D batteries.

I bought two aftermarket replacement batteries for my circa 1998 18volt DeWalt drill driver. They've worked okay. I don't use it a whole lot. If I had to buy the DeWalt batteries I would just buy a new drill driver like the Ryobi 18volt I bought to keep in my sister's apartment in Virginia. It's lighter, cheaper and works great. It just bothers me to dump a perfectly good tool :-(.

Aloha, JB:
I stop buying the disposal batteries. I switched to Duracell rechargeable. I charge them during the day when our PV system in full production.

I hate to dump a perfectly good tool too.
Several of my DeWalt power tools died--just too old. Few served us for over 13 years! Recycled them. We use them A LOT too! I am slowly replacing them with Makita. They seems to be lighter and smaller but pretty powerful 18v tools. I like them so far after almost 8 months of fairly heavy use.

If this is coming from you, I will never question it! 🙂 After seeing your iPhone repair skills--you are really good at this! :good:

I have had good luck with primecell, but they are costly.
