Logitech MX Anywhere 3 Battery Replacement

What you need

  1. Logitech MX Anywhere 3 Battery Replacement, Soften the mouse feet adhesive: step 1, image 1 of 2 Logitech MX Anywhere 3 Battery Replacement, Soften the mouse feet adhesive: step 1, image 2 of 2
    • Flip the mouse's power switch into the OFF position, unplug any cables, and flip it over so the feet are facing up.

    • The unique shape of some mice can prevent them from laying flat. If you need to, lay your mouse on a soft towel to prevent wobble.

    • If you're planning to reuse your existing mouse feet, note that the adhesive needs to be thoroughly heated for them to be cleanly removed.

    • Heat an iOpener and apply it to the mouse feet for about two minutes.

    • Alternatively, you can use a hair dryer to soften the mouse feet adhesive.

    • When using a hair dryer, don't heat the feet for more than a couple seconds at a time—anything hotter than just warm to the touch risks melting or warping the plastic lower case.

    • Push the tip of an opening pick underneath the mouse foot adhesive, into the gap in the rim.

    • Go slowly, and make sure the pick slides underneath both the foot and its adhesive pad. These layers separate easily.

    • If you plan on reusing your mouse feet, be careful not to crease them or separate them from their adhesive pads.

    • Slide your pick under the foot to separate its adhesive until you can grab it with your fingers.

    • Repeat to remove the three remaining mouse feet.

    • For installing new mouse feet or reusing your old ones:

    • Use a pair of tweezers or a spudger to remove any large chunks of leftover adhesive. Thoroughly clean the bottom of the mouse with isopropyl alcohol and a lint-free of microfiber cloth. Allow the surface to dry completely.

    • Peel your new mouse feet away from their adhesive liners and press them firmly into place.

    • Gently open the top half of the mouse up and flip it over to the right, like a book.

    • Don't try to fully remove the top shell just yet—a cable connects the upper shell to the lower case.

  6. Logitech MX Anywhere 3 Battery Replacement, Disconnect the interconnect cable: step 6, image 1 of 2 Logitech MX Anywhere 3 Battery Replacement, Disconnect the interconnect cable: step 6, image 2 of 2

    • Insert each arm of a pair of pointed tweezers into the cutouts on the side of the battery connector's motherboard socket.

    • Push the connector out of its socket, just enough to grip the top of the connector with another pair of tweezers or your fingers.

    • Be careful not to let your tweezers slip out and damage the motherboard.

    • Pull the battery connector completely out of its socket to disconnect it.

    • Try not to bend, crease, deform, poke, or puncture the battery with your tool—a damaged battery is a potential fire hazard.

    • Insert the flat end of a spudger between the battery and its housing through one of the cutouts.

    • Pull up to peel the battery away from the adhesive.

    • Remove the battery.

    • To install a new battery:

    • Use a spudger or your fingers to peel any old adhesive off of the battery housing. The old adhesive shouldn't leave any residue.

    • If your new battery doesn't come with preinstalled adhesive, place a couple strips of double-sided tape into the battery housing.

    • Orient your new battery so its cables route through the cutout in the corner of the housing. Press the battery firmly into place to secure it.

I just read the procedure for replacing the batteries on my MX Anywhere 3 mouse. It is the most ridiculous process I have ever seen. Logitech why have you designed this mouse as a throwaway? It obviously wasn't designed with the ability to just replace a bad battery with a good one through a simple swap typical of standard mice. For example Logitech's M-RAA93, P/N 830918-0000 is a straight exchange of 2 AA 1.5 V batteries !
