Be Prepared with Spare M18™ Batteries on Your Belt
Share
Your battery dies halfway up the ladder. The spare is sitting on the tailgate, fifty feet and two trips away. Every contractor and weekend DIYer knows that walk. An M18™ battery belt holder puts the spare right on your hip, so a battery swap takes five seconds instead of five minutes.

How it works
- Slide the holder onto an M18™ battery until it clicks, the same way a battery slides onto a tool.
- Clip it to your belt.
- When your tool dies, pull the fresh battery off your belt, swap, and put the dead one in the holder.
No tools, no straps, no pouch to dig through.
Open clip or closed clip?
Our M18™ battery belt holder comes in two designs:
| Open clip | Closed clip | |
|---|---|---|
| Putting it on | Clips over your belt, no need to take the belt off | Your belt feeds through it |
| Hold | Grip teeth keep it from sliding around | Locked on, it can't come off the belt |
| Best for | Moving it between belts, pockets and bags during the day | Ladders, roofs and anywhere a dropped battery is a problem |

Which batteries does it fit?
It's compatible with Milwaukee® M18™ REDLITHIUM™ batteries in every size: compact, XC, HD, High Output and FORGE™.
Who it's for
- Electricians and plumbers crawling through attics and crawl spaces
- Framers and roofers who don't want to climb down for a battery
- Landscapers running trimmers and blowers all day
- Homeowners doing yard work, decks and fences on the weekend
Smart ways to use battery holders
- Color-code your charge. Put charged batteries in red holders and dead ones in black. One look tells you which to grab.
- Carry two for big days. Wear one on each side for all-day runtime.
- Park them in the truck. A battery in a holder can clip to a visor strap, a bag handle or a tool bucket.
- Outfit the crew. A 4-pack covers a small crew or several tools.
- Pair it with yard tools. Keep a spare on your belt while you trim and blow. Then hang the blower on a wall mount when you're done.
Pack sizes
- 1-Pack: $13.95
- 2-Pack: for two spares, or one for you and one for a helper
- 4-Pack: $34.15 for the crew
Every pack comes in red or black, with open or closed clips.
A great gift for tool lovers
If someone in your life owns more red tools than shoes, a battery belt holder is an easy win for Father's Day, birthdays or a Christmas stocking.
Frequently asked questions
Will a heavy battery pull my pants down?
The bigger HD and High Output batteries are heavy, so wear a sturdy work belt. The closed clip holds tightest.

Yes. It's made from a tough, impact-resistant material that stands up to heat and UV, and it's built for daily jobsite use.
Are batteries included?
No, just the holder.
Where is it made?
Made in the USA.
