VANTTECHUpgraded 2Pack 12V 6.0Ah Lithium Replacement for Milwaukee 12V Battery 48-11-2420 48-11-2440 48-11-2402 48-11-2411 Compatible with Milwaukee 12Volt Cordless Power Tools

overall there good batteries they charge fast they hold a charge for a long time but the plastic case there in is very fragile one of mine got bumped off a stool and fell about 2 feet and it shattered like glass a little tape later it still works and charges but doesn't have good retention in the tool

Have only used once, so can't give you a stronger review. But, so far so good. Can't say anything about battery life. Usage life? Used it in a small reciprocating saw to cut small branches and to notch in a PT 4x4 and all performed well. Two hours of use before it got tired.

These have a great life my only complaint is the locking tabs will break after about a years of use. Making the battery pack useless. This is my second set. Still being very careful during battery swapping I'm hoping this set gives me a longer life.

Overall they work good, after months of use the lock tabs did break off of one battery so it no longer locks into the tool but other then that they are great

Well I've charged them both up an I use one in my M12 work light which I use as an all around flash light, you know to look for stuff I drop while working, stuff in the closet, and stuff buried beneath stuff ect ect. And the battery seems to be holding up pretty well, I seem to always be using the work light. The other battery gets swapped between the drill, impact driver, and ratchet. I use them often and it's still on it's first charge and showing full charge, so so good, so far. The price was excellent. I'm gonna purchase the 9 ah batteries next. Don't doubt the batteries that came with the tools cause they hold up good for their rating, I was impressed with them too!

Had one battery go bad shortly after starting use. Company replaced it quick with no issues. I have found, compared to the comparable milwuakee brand, these will not run a drill or impact under high load. They are good for smaller bolts/nuts with impact, smaller drill bits/wire brush in/on the drill, and use in the ratchet.

well IF you can get the battery to work they last a good while but 9/10 times i pull the trigger it flashes cuz the battery isnt seated correctly. 0 issues with my Milwaukee batteries. if i need more i will just spend the extra so i know my tools work.

Battery works fine in my M12 tools, really added the power that my cutoff saw was lacking on a 2Ah battery. Can't beat the price either!However the retaining tabs broke off on one of them, an issue a few other reviews mentioned. I have since emailed them twice at their "[email protected]" address where they direct you for warranty claims. Once on January 18th with no response and then again on March 8th, still with no response.
