Topbatt Replace for Milwaukee 18V Battery 6.0Ah XC High Capacity Lithium M18B 48-11-1820 48-11-1828 48-11-1840 48-11-1850 Cordless Tools 2Packs

I bought these even with the mixed reviews. I am a commercial/industrial hvac installer/welder and use 4 of these along with 4 oem 5.0's. They are used in impact guns, drills, grinders, sawzalls, sds hammer drills, band saws, and 1500 lumens light. I have had them since Sept of 18. They keep right up with the Milwaukee batteries, and even recover a bar after heavy use. I did find a glitch with them by accident, I have an older charger that has two separate led for charging and done, batteries charge fine with this, I got a second charger to keep up on heavy use days, a new one that has a single led thst changes color from red to green when done. The new charger wouldn't charge these batteries. I found another older charger at my companies shop and that worksFine. So topbatt needs to reverse engineer the new chargers to see what has changed.

Thank you again Mr. Cheepo Chinese Crap! I bought these in August of 2018 and they were dead by December. I see that I can not get my money back, so folks, STAY AWAY. I'm not a power user; I don't need these everyday for work. I used them regularly on a weekly basis until they stopped holding a charge. One day, they just stopped working. They would not recharge. They were dead as a Chinese fortune. Mrs. Amazon, why can't I return these?

I have had these for 12 hours now. One works fine and charges fine; the other is dead out of the box. It will not accept a charge. Same charger, different results. Not happy, because I only got one good battery, and for the price I could have just gotten an OEM replacement.^^***** Changed from 2 star t o 5 after seller sent me another, and it works. I guess I just got a dud. These have been working well so far

These batteries are worthless!!I purchased these batteries and they replaced them once, but I’m past the return window so I’m screwed

bought two sets from two different suppliers, (darui and topbatt) but they appear to be indentical both in appearance and pricewas initially very happy with the product but time has proven my skepticism to have been justifiedhave one which is completely dead, two which never get beyond two bars and one which appears to fully charge but triggers the fault light every time

Havent had them for a year and one already isnt charging. Havent had any kind of heavy usage, maybe a handful of times. They don't even like to charge in the first place you might as well save your money and buy actual milwaukee batteries

Worked fine for a little over 5 months, both quit suddenly a few days apart.

They dont seem to last as long as the original batteries but are good for the price
