There’s no denying that Milwaukee is one of the most reliable brands out there. The company offers products that provide the user with all the basic things that they will need to complete tasks that require power tools.

Most Common Milwaukee M18 Battery Problems

Apart from power tools, Milwaukee also offers a variety of different battery configurations that you can go for. Depending on the power tool that you are planning to use on, all their configurations provide exceptional quality. However, certain users have been complaining about their past experiences with their batteries as they seem to be running into various issues.

In case you have also been facing problems with the Milwaukee M18 battery, then you have come to the right place! In this article, we will be mentioning some of the most common problems with this particular battery model along with how you can fix them. Here’s everything that you need to know!

  1. Battery Won’t Charge at All!

Battery not charging is an issue that you might face on pretty much every single battery. However, if you are facing this issue with the Milwaukee M18, then we recommend that you first monitor the behavior of the battery while attempting to charge it.

First, check whether there is any kind of visual queue that the battery is charging or not. Some users have reported seeing an instant green light that starts flashing as soon as they start charging their batteries.

It is also important to mention that you should make sure that your battery reaches room temperature before you attempt to charge these batteries. If nothing seems to work, then we suggest that you check if you can still claim a warranty for the batteries.

  1. Dead Battery

Weirdly enough, it seems that Milwaukee batteries have a common issue where most of their batteries die out after a while. As users don’t usually have an idea about it.  As a result, they start assuming that their batteries are dead and opt for a replacement.

However, we found out that in most cases, the battery isn’t completely dead. In fact, all that the battery needs are a jump start which triggers the battery to start working again. That being said, here’s how you can jump-start your batteries if you find them to stop working all of a sudden:

  • Try placing a 9-volt battery on the leads of your dead battery.
  • Keep them at that place for around 30 seconds.
  • Keep in mind that the single lead on the battery represents positive while the double lead represents negative.
  • Afterward, try plugging the battery inside the charger again. It should start charging again.
  1. Batteries Giving Poor Timing

One of the last few common problems that you might run into while using these batteries is getting poor charge timings on it. Simply put, you will notice the battery drying up a lot sooner than it should. While there could be plenty of reasons as to why this could be happening, we recommend that you first check whether you are properly charging your batteries or not.

Over time, batteries tend to start wearing out. Similarly, it could be that your battery is about to go bad. Either way, if you have been using the batteries for too long, or haven’t been really taking care of it, chances are that you will have to get them replaced.

Alternatively, you can try contacting customer support for additional help. If your batteries are still under warranty, you should be able to get them replaced for free.

The Bottom Line:

Are you sick of experiencing problems with the Milwaukee M18 battery? If so, then all you need to do is to follow the set of instructions that we have mentioned in the article. We have listed all the common problems that you might have run into. Simply following the guidelines should result in a quick and easy fix.

  1. I have an M18 1200 series battery that came with my chain saw.. it won’t hold a charge. I get 3 bars out of 4 lights up and then the charger goes green. It gives me about 10 minutes of service and then it’s dead…

    Pretty sad service for a two year old battery. 289.00 replacement… ? I have other Milwaukee M18 tools and the smaller 6.0 runs for an hour using the saw. Will it hurt my saw using it? .

  2. What does “placing a 9 volt battery on the leads of your dead battery” mean? I have 5 slots on my dead battery are those leads? . It is a m18 hd 9.0 Milwaukee.

  3. Same problem hear. Very disappointing to buy a supposedly top brand (highly recommended by everyone) and to have battery issues. I have 3 m18 6ah battery packs. One charges to 3 bars (supposed to go to 4 bars) and green light comes on the charger (which means it’s charged). My other two charge to 2 bars and then the charges goes green and stops charging them. there about 1 year old with mild use. I just bought a couple of cheap knock off ones from ebay, they will probably last longer than the genuine ones. What’s the point of paying top dollar for genuine is they don’t last. Also note that I bought a brand new charger (thinking that my charger had an issue), but still the same problem.
