Ordering your A3 Retrofit Kit is fast and easy. The kit part number corresponds to the wrench size. Order today and we will get the kits out to you quickly.
You can quickly and easily convert your existing 6-volt radio and battery board to the new AAA (A3) radio and battery board. All you need is a small Phillips head screwdriver, needle-nose pliers, and the A3 Retrofit Kit.
The A3 battery has a significantly longer battery life. Changing the battery with the new A3 configuration takes less than a minute.
The newly raised Fresnel improves visibility from less than optimal angles during wrench usage.
We have both written instructions as well as video instructions to walk you through the process.
Making the change from the 6-volt battery and board to the new A3 takes less than five minutes.
The video instructions are found near the bottom of this page. You can also download the retrofit kit instructions here as well.
