How to DIY Mouse Battery Fix?

Even if your mouse looks fine after a drop from a high place, you might notice issues like the current being 20mA and the regular AA batteries not working. How should you handle this?

You might want to check out this article and consider making your own AA battery replacement.

Materials:

· Discarded mosquito trap battery (charges quickly)

· A small piece of bamboo (similar in size to an AA battery)

· Small wires, copper foil (for the negative terminal), and a small piece of 1.6-2.0mm PCB (for the positive terminal)

The process is quite simple. Let's look at the result.

Comparison First:

The battery is made from bamboo, which is easy to work with.

For the positive terminal, align it with the groove of the mouse, and it doesn't need to be a protruding dot.

Negative Terminal:

Ensure the positive terminal matches the size of the groove.

Here's how it looks once placed inside— it doesn't affect the lid. Mosquito trap batteries usually have 2.4V, so no need to worry about compatibility.

After testing, a full charge should last between half a day to a full day.

If your original battery seems faulty, you can test the capacitor on the board. If no major issues are found, it could be a manufacturing defect. Try removing it to see if it's a capacitor issue—often, it's a capacitor that needs boosting. You can troubleshoot it yourself.
