waitley 2 Pack 12V 9Ah Replacement Battery Compatible with Milwaukee 12V Power Tools (Not Made in Milwaukee)

Works great. Had one issue with a battery and they replaced it.

Perfect fit, work ok so far Good price. Have not put them to hard test as yet

I’ve used Waitley replacement batteries for years, I’ve never had a single problem with a bad lithium cell. There’s a great deal of aftermarket batteries out there, they use very good quality parts. I am very pleased with them. I had an issue one time with the tabs breaking off of a battery, and they sent me a replacement part within the week, they have good customer service you could do worse than purchasing this product.

Worth the lower cost than OEM batteries, but purchase twice the amount. It’s the ame with any knockoff replacement battery, whether it’s Milwaukee, Dewalt or Ridged. They charge ok but run down their charge much quicker than the OEM batteries. LED charge indication lights on any brand fail which is not too much of an issue, but remember they are less than half the price of OEM’s with lesser quality rechargeable batteries and LED’s.

Great batteries, i have a bunch of these and they haven't had any issues whatsoever, good output, charge like they should, fit the tools well, for DIY'ers that don't need to spend a fortune on OEM batteries these are great. I have tried a few different aftermarket batteries and the Waitley ones have been the reliable replacements.

These are garbage, I assumed they display 9.0AH i should expect half of that. These are worse than my milwaukee oem 2.0ah batteries. They wont stay in the tool, they dont work in the cold, they go from 4 to 2 bars within 30 mins of use then always have 2 bars, yet work as if they're dead.

Well, I got my two 9 Ah batteries that fit the Milwaukee M12 series. I’d read that brand-new ones sometimes don’t charge or work right out of the box. But I was ready for that — the price for two 9.0 Ah batteries was almost three times lower than the price of a single original 5.0 Ah battery from Home Depot. Luckily for me, both work perfectly and both charge. I tested them on a drill and a flashlight — everything works as it should. For this price — it’s just excellent! Highly recommend.

These batteries work great with all my milwaukee tools no issues so far I was slightly hesitant because they weren't factor .but wow im impressed
