Retrofit Replacement Housing for Milwaukee 5AH & 6AH Non High Output Batteries with Built in GPS 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 or Android Find Hub.
We have carefully redesigned the genuine housings by extending the overall length by 2mm and introduced a pocket that holds a custom tracking card internally underneath the cells so it is undetectable. It has been carefully engineered to allow for the existing size of the internal components and structural integrity while discretely having a pairing/reset hole on the bottom to control the tracker from the outside.
Swap your existing cells into this shell and your battery shows up in the Find My or Find Hub app right next to your phone. If it goes missing, you'll see exactly where it is — powered by Apple's and Google's global networks of billions of devices. No subscriptions, no separate app, no monthly fees.
Why you'll want one
- Works with Apple Find My or Android Find Hub — choose your version at checkout and locate your battery from your iPhone, iPad, Mac or Android phone, anywhere the network reaches.
- 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.
- 2 year warranty — backed by Betta Battery's two-year warranty.
