Logitech MX Anywhere 2 Battery Replacement

Difficulty

Moderate

Steps

Time Required

30 - 45 minutes

Introduction

Use this guide to replace the battery in your Logitech MX Anywhere 2 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 Anywhere 2 has a relatively small battery, any charged battery is a potential safety hazard if accidentally bent or punctured.

Parts

Step 1

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.

Step 2

Insert an opening pick between a mouse 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.

Step 3

Peel up and remove the mouse foot.

Step 4

Repeat the previous two steps to remove the remaining mouse feet.

Step 5

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.

Step 6

Use a Phillips screwdriver to remove the four 5.9 mm-long screws securing the lower case to the upper shell.

Step 7

Flip your mouse over and grab the upper shell.
Lift the front edge of the upper shell upwards.
Lift the upper shell straight off of the mouse.
During reassembly, lay the front edge of the upper shell into place, then press down to engage the rear clip.

Step 8

Use the point of your spudger to pull the battery cables out from under the cable guide on the battery housing.

Step 9

Use a pair of tweezers or your fingers to grip the top of the battery connector.
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.
The connector is held tightly within its socket. If it feels stuck, try a different grip—use the protrusions around the neck of the connector if you need more leverage.
If the connector won't budge, skip to the next step for an alternate method.

Step 10

If your battery connector still feels stuck:
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 up, just enough to grip the top of the connector with another pair of tweezers or your fingers.
Pull the battery connector completely out of its socket to disconnect it.

Step 11

Use a Philips screwdriver to remove the three 4.7 mm-long screws securing the battery housing.

Step 12

Remove the battery housing.

Step 13

The battery is secured within its housing by some light adhesive.
Flip the battery housing over so the battery is facing down.
Apply a heated iOpener to the battery housing for about 2 minutes to soften the battery adhesive.

Step 14

Try not to bend, crease, deform, poke, or puncture the battery with your tool—a damaged battery is a potential fire hazard.
Insert your opening pick between the short edge of the battery and its housing, opposite the cable.
Slide your pick under the battery to slice the adhesive.
If the battery feels stuck, slide your pick around the perimeter to slice any remaining adhesive.
Pull up to peel the battery away from the adhesive.

Step 15

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.

Conclusion

Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before you install it.

To reassemble your device, follow these instructions in reverse order.

For optimal performance, calibrate your newly installed battery after completing this guide.
