Mrupoo 18V XC 9.0Ah Lithium-Ion Replacement Battery Compatible with Milwaukee 48-11-1840 48-11-1815 48-11-1820 48-11-1828 48-11-1890 Milwaukee Batteery,US Shipment

Doesn’t seem to hold a charge quite as good as the Milwaukee battery but still a good value

Only the Milwaukee brands will hold a proper charge

The batteries would not charge I evan tried it on a different charger and that charger will charge other batteries charged with no problems but the 9 amp batteries would not charge at all light on charger flashed that the were defective

1 month in so far this is great. I use it to power long use tools and it hasn't given up yet

That was true it doesn't work on all Milwaukee tools. What I noticed was it won't charge on all battery chargers either. On some chargers it says it is a broken battery (all rapid charge chargers). Therefore I am in doubt every time I put it on a charger whether or not it's going to charge.

DO NOT BUY!!!! WILL NOT CHARGE!!! VERY EXPENSIVE FOR A SINGLE USE BATTERY!!!!

It works like the original equip batteries. Time will tell if it holds up as well.

So far so good. I haven’t had them long to give a better review. They came with a good charge. They also charge with my Milwaukee charger.
