Since it is a 1.21 gigawatt battery, it should last 4 to 6 years and actually IS user replaceable or lacking a suitable replacement you can run it off a power bank if you happen to have an old Mr. Fusion miniature reactor lying around in the garage next to your DeLorean.
There is just no need to go to the trouble of taking the control head off the shaft to access and remove a lithium battery simply to lay up the detector over the winter.
So no need for histrionics from the AA battery crowd looking for yet another ridiculous reason to bash the Equinox.
Not saying that's where you were headed, with your post, your majesty, but just wanted to nip that in the bud because a post like yours seems to be like catnip for attracting certain Garrett, Tesoro, and Whites users who seem to be highly offended the Equinox even exists. It just gets a little old after awhile...
