Logitech MX Master Battery Replacement

简介

Use this guide to replace the battery in your Logitech MX Master mouse.

Lithium-ion batteries have a limited lifespan. If your mouse dies quickly, it may be time to replace the battery.

If possible, follow this guide after your battery has fallen below 25% charge. While your MX Master has a relatively small battery, any charged battery is a potential safety hazard if accidentally bent or punctured.

    • 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.

    • Apply a heated iOpener to the left and right mouse feet for about one minute each.

    • 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.

    • The information sticker adhesive may soften during this step, but you don't need to remove it.

    • Insert an opening pick between the left foot and the lower case.

    • 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.

    • 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.

    • Always pull cables by their connectors and not the wires themselves.

    • Gently rock the connector side to side and pull it out of its socket.

    • 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.

Thank you so much for this guide! My MX Master’s battery life has been slowly dwindling. I made the mistake of not verifying my original battery’s dimensions, roughly 1” x 1.25”, about a third of the size of the replacement I ordered. Was still able to swap batteries (from 500mah to 1150mah) by swapping connectors and removing the battery holder compartment. The new battery’s size is sufficient to avoid movement, but used a drop of adhesive just in case.

Does anyone know where to find the correct size replacement battery? Thanks

I used a larger Lipo battery of the same voltage, and soldered the cables from the original... upgrade!
