| How To Fix Milwaukee Battery M12 |
Step 1: Diagnose the Patient (Your Battery)
- The Classic "Red and Green Flashing Blues": This light show usually indicates a low voltage cell inside the battery. Fear not, this might be an easy fix!
- The "Stone Cold Dead" Situation: If your battery refuses to even acknowledge the existence of a charger, you might have a more serious problem. But hey, there's no harm in trying a little troubleshooting.
Step 2: The Jump Start - A Tale of Two Batteries
This method is perfect for those "Red and Green Flashing Blues" we mentioned earlier. Here's what you'll need:
- A healthy, fully charged M12 battery. This will be your battery samaritan.
- A couple of jumper wires. Think of them as jumper cables for the miniature battery world.
Now for the fun part! (Caution: Following steps involve opening the battery. Only attempt this if you're comfortable.)
- Identify the good and the not-so-good batteries.
- Carefully crack open the cases (YouTube can be your friend here for some visual guidance).
- Connect the positive terminal of the good battery to the positive terminal of the ailing battery, and do the same for the negative terminals. Be very careful not to let the wires touch! Sparks will fly (not literally, but a short circuit is bad news).
- Let them hold hands for a few minutes. Think of it as a battery pep talk.
- Disconnect the jumper wires and put those battery cases back together.
- Pop the not-so-good battery in the charger. Hopefully, it'll be ready to rejoin the fight after a full charge.
Pro Tip: If you're feeling a little nervous about cracking open the battery casings, some folks have reported success with simply touching the positive and negative terminals of the two batteries together for a short period.

Step 3: When All Else Fails...
Sometimes, even the best intentions and jumper cables can't save the day. If your battery is truly deceased, it might be time to consider a replacement. However, before you do, make sure to check the warranty on your battery. Those Milwaukee warranties can be lifesavers (or should we say, power-savers?).
