Bought to drill clearance holes for plumbing underneath a house. Heavy work. Performed well. Worked hard until discharged, several times, recharged , and continued again, several times, Had to cool hammer drill with compressrd air, batteries held up to tough work very well, recharged and using on weed trimmer now. Still work well! Good results on a Heavy Duty Battery ( X2) worked to extreme! Would buy again, when needed. Now use them with adapter, on other tools, when needed. They work well on heavy load of chain saw.

I have two of these batteries that I purchased the end of January 2023. Now in November 2023 I have two dead batteries. The batteries were not over used. They don't hold a charge. The release clips get stuck open. They are not as powerful. I can feel the difference between these & Milwaukee batteries. These batteries lose there power quicker than the milwaukee batteries. So again DO NOT PURCHASE THESE! JUNK! Wish I could give ZERO stars.

But they don't seem to hold a great charge. For work I have to cut a lot of cast iron with a sawzall. Brand new batteries will get about halfway through a 4 inch pipe before it dies. Not as good as Milwaukee but also much cheaper

Tradesman here. I work with tools for living. I am using power tools every day, 8 hour a day. It is clear to me that some claim that these "cheap batteries" are not worth buying - but fortunately for me, they always worked great. Savings over branded batteries are so high that even if I need to replace one or two of these batteries after few months of use - still, they are LOT better deal than going with the brand, that is 4x more expensive. Thank you.

These are a pretty good deal for the money. I have several tools that take this style of batteries. This will make it nice to rotate them thru as we use them.

We bought a pair of these to go with a small Milwaukee vacuum. Thought the aftermarket battery would be fine for light housekeeping use. First pair came and one of the batteries would never take a charge. I own several chargers and same results from all of them. We exchanged them for a fresh set. Second set came and worked for about a month then one of them wouldn’t take a charge. Another month passed and now neither work. What a waste and rip off. Now they are off to the recycler or land fill. Don’t waste your money on this garbage.

The media could not be loaded. Ok so bottom line is it's a cheap battery and they will work... but not exactly reliably. First the battery indicators are dim and hard to see, no big deal. I had 1 kick the bucket after a month with almost no use. Big deal. Went through Amazon to get the replacement and postponed the return cause I expected another to go quick, now I missed the time and had to pay again, lessons... There's a built in surge protector of sorts and if you're using a tool that draws too much at any time, it glitches out and stops for a minute, kinda like a mini seizure. Also, I've had an issue with having to hit a trigger or turn on tools 2 or even 3 times for them to start working, and this happens no matter what the charge or age of the battery. All in all, absolutely infuriating. These will absolutely not work in a larger tool like the leaf blower, and if you're ripping something long like plywood, expect to do it in 2 or 3 goes. Originals are pricey but good. I've bought other knockoff batteries that have been working for years too. I should have returned these and gone another way though, but at least I have 2 crudy backups 🤦‍♂️

Ok so one thing I did notice is after charging just using it goes done to 3 bars. However I have found it can be at 3 bars for a long time. I'm a diesel tech and use them daily and won't have to charge them till the next week and I do 12 hour days. I think it's just how they read it and does not mean it drained fast but not at 100 percent and goes 3 bars at 98 percent. Recommended to other techs and would buy again.
