Great fitment, Hold their own against Milwaukee’s
I bought these batteries to have extra ones when I’m working so I don’t have to wait and recharge, but these compare to the factory ones don’t last nearly as long. They fit well but run out of juice rather quickly. Maybe I got some bad ones.
One of the two batteries is a dud!… But was replaced.
Received these batteries today. Both batteries are a bit loose between the red body and black cap. Also the batteries don’t quite fit in the tool correctly. But those issue are exceptable. Thank fact that one of the two batteries does not charge streight out of the box. My Milwaukee charger blinks red/green indicating the battery is bad/faulty. Awaiting vendor response.
Perfect fit replacement for Milwaukee 12v tools and work with Milwaukee’s charger.
Great buy to replace Milwaukee 12v batteries. This twin pack cost half as much as a single Milwaukee brand battery. I have a few of the 12v tools that are quite handy and these batteries are a solid replacement for the stock battery packs at substantial savings. They both charged easily with the stock Milwaukee charger and provide solid power to the 12v tools I have. The only difference I can note for sure between these and the stock batteries is that the stock batteries are marked as 14 wH (watt hour) and the powerextra brand is marked as 30 wH. The powerextra is a 2500mAh battery but the stock batteries do not indicate on them the mAh rating so am unsure if this is larger or not. I did measure them and the outside size of the batteries are the exact same size as the stock batteries so if they are larger it must be a different design of the battery cell compartment internally. Will post an update in 6-12 months to tell how well these hold up over time. So far would definitely recommend.
hey work as well as the name brand one.
Purchased these to be used in a Milwaukee heated jacked. They work as well as the name brand one. I will be purchasing again. Fits perfectly in to the charger as well as the power port on the jacket.
Amazing value. Haven’t noticed a bit of difference between the Milwaukee batteries that came with my tools, but I’m not a contractor operating in sub-zero temps either.
I was a little hesitant to purchase these batteries, as they were not a “Name brand”. I have made that mistake before. Well, after receiving them, they were packed so well, I thought that if the battery is half as good as the packing, it will be OK. They took a charge quickly, and I installed them in my heated jacket. They worked as well as, or better than, the “Name brand” ! They have the look and feel of a high quality part. I don’t think you can go wrong with these batteries. The only test left, is to see how they hold up after the long winter ! I am well pleased so far.
Two for the price of half of one!
Have used powerextra batteries crossed 2 platforms now and they are a great value option. Work well with my m12 impact and comparing to the m12 batteries the only difference is not having Milwaukee decals. Good battery life and work with the units battery gauge.
Seems like a good battery only time will tell.
Build seems good enough for the price. Using them in m12 fuel impact and drill daily as a solar technician. We will see how they hold up in freezing temps and abuse. Only thing I’m worried about are the clips that hold it in each tool. I had to pry mine out on the battery so they would not slip out of my impact in the drill they worked perfectly. For do it yourself around the house seem fine for daily use abuse only time will tell.
Great for the price (so far)
I’m usually a “stay away from knock offs” guy… But these are working just as good if not better than the OE Milwaukee M12’s at a lot better price. We’ll see how they hold up when the cold weather hits. It gets pretty cold out in my shop in the winter and usually kills my cordless power tools batteries.
Had my sawzall sitting around with a bad battery. Bought the 2 pack with a higher power rating at half the price. Can’t beat this deal. Two extra surprise gifts which were appreciated. One of my best Amazon purchases.
