This is the real deal. Or at least the one I got. Identical in every way to the 2A I got with my drill.

Been using the 1.5 for a year and a half, and these are far superior both in the power and the time that they can be used before needing recharging. Arrived when they said they would very good product.

I purchased this battery for a standby flashlight. I've only charged it a few times, but now it won't even accept a charge. When put on the charger, the charger show green. On the battery, the button indicator show one bar, and its blinking red. This battery does me no good, make the flashlight useless.Even out of warrenty, I should get more use than I have.I would like to hear from the seller, but I seriously doubt I will..Update: It's been two weeks and haven't heard from the seller. I think I was scammed.

the reviews had me questioning if this battery is worth buying or if it was a fake but the one i received came in real milwaukee packaging and it is identical to the real m18 5.0 battery in the pictures. charged up just fine and it even has security torx screws like the real battery’s. compared every little detail from this one and my real battery and they’re indentical. very pleased with this purchase as i felt the 2.0 for $100 at home depot was super overpriced. this has the same power as my real 5.0 and is half the size and weight.love it for my impact driver.
