How old are they? You can expect one year out of these batteries, and that is about it. I have boxes full of dead batteries, hoping they will be worth something someday as rare chemicals. No, just saving up for a trip to the recycling bin. But every year I buy a new set, mark the with a sharpie, that is how I know they only last a year, because I have been doing it for 10 years. Hope this helps.

I charge my batteries but when I use them they go dead very fast

Your batteries no longer hold charge as deeply as they once were capable. Typical symptom of rechargeable batteries. You need to replace them.

Your batteries are at the end of their rope and need to be replaced. All batteries die, some sooner, some later. And if you do not maintain them in a manner consistent with directions they will fail sooner!

My 28v milwaukee batteries do not last any time and they are only a couple of years old

Unfortunately even rechargable batteries have a limited lifespan. Two years is good, if you get three years out of one you're doing very well. Lifespan is determined by how much you use then, how many recharges you put on them and how far down you drain them between charges. The more power you take out of a battery before charging it back up the better. Also, there are no repairable parts inside a battery and no way to recondition them once they're worn out. Sorry, not what you want to hear, but the only fix is to buy a new battery.

Lookup your local Milwaukee dealer and head over with your drill, they can test it for you and probably source you a charger or if its too pricey, check Amazon & eBay.

Why my 28v doesn't fully charge. when charging indicator light is red. there is 4 charge indicator. when it reach 2 green light comes on showing fully charged. you would use it for about 20 minutes and...

One or more cells of the battery have gone bad. The technique of measuring the state of charge of the battery is VERY limited.

I would recommend letting the battery cool after charging... THEN in a day, charge it again without using it. Do this for several days and see if the battery improves. If not, time for new battery.

DO NOT discharge these batteries beyond the point where the tool starts to slow down. You will reverse charge the weakest cell from the ones still deliveing power and the reverse charge will permanently damage the weakest cell.

you can try and unplug the charger for a couple minutes and then retry. I have a LiIon at work and sometimes it does it also, if not then the batterys would probably be bad, I would contact and see about warranty replacement for these. They have a good warranty on the newer products.

Battery drains quickly. Loses charge when plugged

Sounds like you need a battery. The key here is that the battery is losing charge while it is supposed to be charging. Works like a car battery, even if the alternator is working 100%, if the battery is pooched, the car won't start.

Milwaukee 28V Lithiom-Ion Battery loses power in storage

It is not recommended to leave the battery installed in the drill while not in use. The system of the drill will eventually pull the battery down, especially if the battery has had a lot of use. When the battery begins to weaken it will not hold its charge as long.

If you haven't, try charging the battery, 24 hours max and then keep it detached from the drill for several weeks. Then try it aand see how much power you have left. If it is low or depleted, battery is weak.
