Introduction
This guide shows you how to disassemble your Glorious Model O 2 Wireless mouse and replace the battery inside.
This guide specifically uses the No. R-R-yG9-Model-OW mouse, PATTENT No. D884,699. Other variants should be extremely similar. The official battery is a HX 582728 3.7V 1.665Wh with 450mAh capacity. The HX code means this is 5.8mm thick, 27mm wide, and 28mm in length. There is some extra room in the housing so you can upgrade the battery if you want (as I will do).
IMPORTANT NOTE #1:
In this guide I replace my battery with a 3.7V 1100mAh HXJNLDC 803040. This battery is larger and heavier than the original battery. It fits snugly in the original place but if you are concerned about weight find a smaller battery. The plus side is that this has more than double the original battery life so lasts much longer. It is about 10g more, but I don't notice much difference. There is also some extra room so you may be able to fit in a battery that is xx3540 or even xx4040 but these are untested. Please add a comment if you have used a larger size.
IMPORTANT NOTE #2:⏎
Finding the right connector can be a bit difficult when shopping online. If you are comfortable with soldering it may be easier to simply buy a battery (make sure it has 3 wires), snip the ends, and solder the wires together. This is what I've done in this guide but do not show this step.
What you need
-
-
First we need to remove the two feet.
-
(Optional, but recommended): Heatgun/hairdryer is to help loosen glue
-
Use your spudger (or a guitar pick) to remove. Lift carefully to not bend too much.
-
Place feet in safe location, they will be quite sticky!
-
Use a Philips head screwdriver to remove the two screws (size is not too important)
-
-
-
Use your screwdriver to push the bottom plate away so you can get your spudger underneath.
-
Use spudger to unhook the 4 clips. Start with the sides and unclip the front last.
-
I've highlighted the location of the 4 clips in the 3rd picture
-
For the front clips be gentle and wiggle backwards until it comes free
-
-
-
-
Order here is unimportant
-
Remove the two ribbon cables from the back
-
(Optional): tweezers may be helpful, but I found these easy enough to remove with just my hands.
-
Disconnect the JST connection
-
And the ribbon cable on the side opposite the JST
-
-
-
First remove the screw (hidden by JST here)
-
Free the circuit board from the clip near the top
-
Carefully remove the battery. It is glued to the spongy material. This will rip
-
-
-
Swap out the battery.
-
Optional: re-glue or tape to housing. I used electrical tape on the bottom, leaving the window open.
-
Reverse process for reassembly.
-
You're done! Happy gaming
-
(Note): I've included a picture of the assembled battery so you can see that there isn't much excess space lengthwise. If you want a bigger battery you can only go heightwise.
-
(Note): Assembled picture does not show optional resoldering. Check your fit, as I have done, before doing any soldering.
-
(Optional, resoldering): If you do not have the right JST connection don't fret! On the original battery cut the wires close to the battery and on the new battery cut close to the connector. Solder the two together. It is highly recommended to use shrink tubing to avoid short circuiting. Soldering steps not shown here.
-
To reassemble your device, follow these instructions in reverse order.
