Not as good as omc charg 5 times stop working after that

Almost 2 years and still going strong!

The price of these replacement batteries sold me on them. 1/3 cheaper than brand name batteries. Longevity and charge rate/quality will be interesting to see. Update to follow.

Haven't used enough to comment on reliability, capacity, etc. But I have the same problem as one other reviewer. The dimension of the plastic housing is .015" larger in one direction than a "genuine" battery. Consequently, It won't fit into my 3/8 cordless ratchet all the way. I can jam it far enough to make electrical contact, but the teeth lack about a 16th in. to snap in place. Then it's hassle removing. I can pry it loose with a screwdriver, but it'll chew up the tool. Shouldn't be that way.

Love these batteries

I use only jobsite radio, they ‘re ggreat for that, and small household stuff, they dont last long for jobsite screwing 18 or 20 volt is what you want fo that , th 12 volt is a good lil house hold item girls love ‘em to ,& lightweight

I use these in the Milwaukee heated jacket and heated hoodie, so it's a low-drain application that does not pull a lot of power all at once, like a circular saw would. I put them in an M12 light and they outlasted the Milwaukee batteries by about 15 minutes but the Milwaukee ones were about a year old so that may be a factor. I haven't had them long enough to judge longevity or durability but they seem to work fine for the purpose I bought them.

This product works with the tool. It fits a bit tight, it's ok. The picture is a bit misleading it shows an m12 battery (Milwaukee) brand. I got was an aftermarket item. It still ok. It would have been nice to know.
