18V 9.0Ah Tool Battery - Replacemnet for Milwaukee Cordless Power Tools Battery and Charger MK-18 48-11-1840 48-11-1828 48-11-1820 48-11-1815 48-11-1850 48-11-1890 2646-22CT Battery (2 Pack)

I used one of these for the first time for string trimming and blowing. I compared it to a Milwaukee brand 12.0. This 9.0 off brand lasted just as long for the same job and had 2 bars left. That's about 40 minutes of string trimming and 5 minutes of blowing.So far so good. Hope it lasts and doesn't overheat like some Lithium Ions do. Even the Milwaukee's sometimes do and I have had bad luck with the 12.0 Milwaukee's lasting more than 3 years.

Battery level indicator lights are very dim and barely visible during the day. Fit tightly like oem. They don't last as long as oem but they are comparable. They seem to take twice as long to charge vs oem, regardless of what charger I use. No overheating as of yet. They work well 👍

BAttery life in between charges

Ordered quite a few of these for work. Use them in a portable air pump. When they work they are of great value, problem is they will randomly completely stop working. One would not charge at all, some quit working after one use. Asked for a replacement from the company, it came 3 months later and was clearly used and would not charge. Save yourself headache and money in the long run and just buy actual Milwaukee batteries.

For two big batteries like this. you cannot beat a price like this.

I ordered these batteries to supplement my existing set up. These hold a charge as long as my original high capacity batteries. They look very similar to my OEM ones except for the labels. If you're looking for replacements these are a much better value than paying the high price of original batteries. These provide the same functionality for a fraction of the price.

Not as long lasting on a grinder as the OEM batteries, but works just as long as the OEM batteries on a work light. In general much better value than OEM

I was super hesitant to try this battery replacement. My husband loves his M18 impact but there never seems to be enough battery. We have the original charger that came with our impact and this battery connects to it just fine. It does charge and work just about the same as the original batteries. It looks the same too and you would have to look really close to tell the difference besides the name on the sides. Where it does differ is the original ones are so much heavier than this one. This battery is very lightweight compared to the original ones. I gave it 4 Stars because they do perform well and take and hold a charge. I think the real test will be the longevity of the battery. So far so good on this one.
