Retrofit Replacement Housing for Milwaukee 5AH and 6AH Batteries with Built in Find My Tracking
The Betta Battery replacement shell gives your Milwaukee M18 18V battery a brand-new housing with one serious upgrade the original never had — a built-in tracker that works with Apple Find My.
Swap your existing cells into this shell and your battery shows up in the Find My app alongside your iPhone, AirPods and AirTags. If it goes missing, you'll see where it is — powered by Apple's global Find My network of over a billion devices. No subscriptions, no separate app, no monthly fees.
Why you'll want one
- Built-in Apple Find My tracking — locate your battery from the Find My app on iPhone, iPad or Mac. Works anywhere the Find My network reaches, which is just about anywhere people carry iPhones.
- Direct fit for Milwaukee M18B6 & M18B5 18V packs — drop-in replacement housing for tired, cracked or sun-faded shells. Give an old battery a second life while adding theft protection.
- IP68 waterproof tracker module — the tracking hardware is sealed against dust and water, built for real job-site conditions.
- Wireless charging — keep the tracker topped up without opening the shell or fiddling with cables. An hour of charge equals a year of operation.
- Designed & assembled in Australia — engineered and put together right here in Burleigh Heads, QLD, by people who actually use the gear.
- 2 year warranty — backed by Betta Battery's two-year warranty for genuine peace of mind.
How it works
- Open your existing battery and transfer the cells and BMS into the new shell.
- Pair the built-in tracker with the Apple Find My app — takes under a minute.
- Clip the battery back on your tool. That's it. If it ever wanders, open Find My and go get it.
