Basically, the dirt acts as a barrier between the metal-to-metal contacts of the charger and the battery. Your charger may not “see” the battery if the contacts are dirty. You’re going to be looking for and correcting the following: If the charger isn’t recognizing any batteries, it’s time to inspect the contacts on both the charger and battery sides. But when you put several different batteries on the charger, it’s like they don’t exist because you’re not getting indicator lights. If you’re getting power at the charger but not getting any light indicators when a battery is on, there may be some things you can do to fix those LEDs.Īt this point, you know there’s electricity at the outlet, the cord is in good shape, and you’re getting voltage at the charger. Milwaukee Charger’s Getting Power but Not Charging Batteries Let’s focus on the charger and battery some more first. If you plug it into a different one, and you’re getting lights or voltage at the charger when you weren’t getting anything out of the first outlet, you now know you have a bad outlet that needs to be addressed. Now if the outlet is an issue, you still need to check the charger on another outlet to make sure it’s okay. If you’re not getting any electrical distribution at the outlet, check the breaker and make sure it’s good to go. Or you can plug something else into the outlet and see if it’s getting power. Well, if you’ve got a multimeter, you can check to see if the outlet is hot. In this case, make sure the outlet you’re plugged into is good to go. Milwaukee Charger isn’t Getting Powerīefore you run out and buy a new charger, let’s eliminate one more thing. It should be reading at least 18V for adequate power to charger a battery.Īt this point, if you’re getting voltage at the charger but no lights once a battery is placed on the charger, you still may be dealing with a battery or charger issue but you know for sure something up with the LEDs (more on this later).Īt least you’ve eliminated the question of whether power’s getting to the charger, right?īut what if you’re not getting any power at the charger? Is it time to toss it and get a new one? 3. If you don’t get any lights, and if you have a multimeter, you can check to see if the charger is getting voltage to determine if it’s just an LED problem. If you do get some form of light of some kind, you know there’s power.

Right now, your only concern is if there’s power. Don’t worry about what the color of the light is or what it means yet.

Well, with a Milwaukee charger, you can do a couple of things.įirst, you drop the dead battery in the charger, or another battery in the charger, and see if any lights come on or start blinking, etc. Now, how do you know if the charger’s getting power? Notice, the question wasn’t, “Is the charger plugged in?” Yes, it’s time to ask the obvious question, “Is the charger getting power?” But if you have a warranty or the charger’s a recent purchase, you may want to contact a customer service center first.Ĭheck the power cord as the first possible problem to avoid moving forward with more complicated and unnecessary fixes. That doesn’t mean the cord can’t be replaced. As noted on page 5 of this manufacturer’s manual, there may not be serviceable parts for repairs. You can attempt to replace the cord but may have an issue finding an official Milwaukee replacement cord. If you find any damage, stop using the charger. If there’s an issue with the charger’s cord, then of course there’ll be an issue with charging dead batteries.Ĭuts, abrasions, or any other sign of damage that would impact the operational capability of the charger. After all, if there’s a problem with it, it would make sense that there’d be an issue with power being transmitted from the outlet to the charger, in this case. When you’re dealing with anything electrical that seems to be having power issues, the first thing you should usually check is the status of the cord. The good news is, if either one’s having issues, there are a solid seven tips you can try to, one, determine if it is the charger or battery, and two, how you can possibly fix it without having to get help or consider a replacement. So, if you’re having trouble with dead batteries charging, in this case Milwaukee lithium-ion batteries, there are two things to take a look at: the charger and the battery.

Yes, the convenience of cutting the power cord from the outlet to the tool is a magical thing that provides freedom of movement without the concern of having enough extension cord.īut with those batteries come the battery charger, which still plugs into an electrical outlet. Well, that is, if the batteries charge up. The total convenience they bring to the table is a game changer. If you haven’t you should check them out. If you’re like a great many other people throughout the world, you’ve probably heard of and invested in these things called cordless power tools.
