Replace with a generic for better results.
Disappointed in this USB 3.0 battery. Two completely separate purchases with different manufacturer dates quit charging after just a few uses. Seems someone overlooked an obvious flaw. An unbranded, generic battery has proved far more reliable.

Battery life short, no battery available for purch
Bought flashlight at Home Depot in Kapolei Hawaii. First battery stopped working now only have second battery left. Tried to buy replacement battery, bit unavailable her in Hawaii and won‘t ship to Hawaii. That‘s a very expensive throw away flashlight. Very disappointed. Beware!

Dissapointed
Battery does not take charge after a few months. Thought Milwaukee was a good brand. Bad reviews repeat over and over about this known issue.
Just contacted Milwaukee for options.

Garbage!
Absolute trash! I can get it to charge but it lasts less than 5 minutes on low before it starts flashing red and shuts off. For the cost, I was expecting much more.

Bad batteries
These batteries are terrible. I’ve had 4 of them fail on me within months of basic use for my head lights. Two of the batteries are less than two months old. Milwaukee needs to fix this issue. I bought them from Home Depot and can’t return them now.

Faulty, DONT BUY!
When it was time to charge the battery for the first time it would not charge. The Home Depot was kind enough to exchange the first one but the 2nd done the same thing and they will not take it back. This is a lot of money for one use! Someone obviously never tested this before releasing to the public.

Very disappointed in Milwaukee
What a joke these batteries are! It's clear as day from this review thread that you have a defective product.
I'm having the exact issue with the battery in my laser. Red and green light when you try to charge. Will not take or hold a charge. Battery is dead.
Sad part is even if Milwaukee ponies up and does the right thing and replaces my battery, the replacement will suffer the same fate.
Disappointed to say the least. Milwaukee has been my go to brand for years, and now I'm stuck with this laser and no way to reliably power it?
My company Ainsworth Inc. also almost exclusively uses Milwaukee tools. Having hundreds, if not thousands of units in union tradesmans hands.
You're better than this guys.

5 batteries, none of them charge consistently.
I have 5 of these 3.0 batteries and I use them accross three different devices, those being the 1100 lumen flashlight, the usb Bluetooth earbuds and a headlamp. I use the flashlight and earbuds daily, they’re very well loved tools to me. With that being said, I started seeing inconsistent charging issues with the batteries after 4-5 months of use. They still hold and charge to a good amount, but while they’re charging the level doesn’t seem to be accurate, regardless of which tool I’m using to charge the batteries. For example, I could leave my flashlight charging all day and it’ll start with the yellow flash and 8 hours later it could still flash yellow but as soon as I unplug it it’ll show green.

decent battery
i havent had issues like the 1 stars here and i use mine everyday but i do sometimes get a flashing green and red light sometimes when using the quick charger and i just have to unplug and replug the battery. the fast charger also does make the batteries charge quicker than they drain so you really only need 2 batteries per light which is nice

FIX THE BATTERY
The battery does not last long and now doesn’t hold any charge at all , I always use Milwaukee tools but for the headlamp I guess I will have to use another brand.
