Intro: Wireless Mouse Rechargable Mod

Hi everyone!

So, everyone of us, who has a wireless mouse, one day wakes up, gets the mouse and obviously the battery is dead, or about to.

And if you're lucky enough, you have a spare battery, but if you don't, either work with the trackpad, or runs to your local store to get a battery.

The idea from this Instructable, began with some cheap xbox 360 controller batteries that i bought a few years ago and never used them,

So one day, just for curiosity, I open one of them, and found 2 batteries inside!

That gets me the idea to use one as replacement for my wireless mouse battery.

Lets get to it!

Step 1: Materials and Tools

Materials:

  • One wireless mouse,
  • One cheap xbox 360 battery, I get mine from here
  • Small wires

Tools

  • Soldering Iron
  • Utility Knife
  • Hot Glue Gun
  • Screwdrivers

Step 2: Tearing Down

First, remove the battery cover and the dead batery. Usually, there are some screws, hidden under plastic, so take that apart too.

Remove all the screws you find, and very carefully, split the mouse to get the inside parts.

Put it aside one moment.

Now, use a slot screwdriver to open the xbox controller battery.

Be carefull!! The wires inside are very thin, and you could make some damage on them.

Inside, you will see 2 batterys connected on series with 2 red and 2 black wires on each end. One pair is for the USB charging port, and the other one, is for the charging led.

Remove one battery, cutting the wires on one end, and cut the wire/metal between the 2 batterys.

Also, take out the circuit insde the mouse too.

Step 3: Fitting the Parts

If you take a close look on the mouse bottom plastic, you'll see that the battery compartment is isolated from the inside.

We'll need make a hole, to fit the battery wires on the inside.

Also, you'll notice that the battery is a litle shorther than a AA one, so we need to add something to keep it steady.

I use some plastic tube to get this.

Once the battery is fixed, take the mouse cover, and make a hole on the back (I usee a small plillips scredriver), to fit the charging led.

Use the utility knife to make a square hole to fit the charging port.

Step 4: Soldering the Electronics

Now: the battery compartment, has 2 spiral wires, one from the positive, and one from the negative.

Our battery has 2 wires to be solder to each side, so make sure you respect the correct polarity.

Add some termofit to isolate the solder points.

Now, fit the chargng led trough the back hole, and place the charging port on the correct position.

Add some hot glue if needed and close the mouse cover, and put the screw.

Step 5: Finished!

And It Is Done!

Now, you just have to connect the usb cable, and let it charge a couple hours.

Hope you guys like it, and please, if you have a comment or a suggestions, share it with us!

    Question 7 months ago on Step 4

    This is great! What is the resistor that is just visible? Are there any other electronic components?

    Hi! This resistor is for the green led, to keep the amperage on a safe
    range. The controller battery only has a barrel plug for the usb cable, a
    led, a resistor and the batteries itself.

    There's nothng more. Thank you for your question!

    This is an interesting mod

    I think a connector for a micro usb cable (as used on android phones etc) would be handier than the connector you've used.

    I don't know enough about it ether way, but do you not need a charge protection circuit to limit any risk of exploding battery?

    Can't help but feel that it would be easier to buy a rechargable battery and charger, or the sort with a self contained usb ( as per https://www.amazon.co.uk/BlueBeach%C2%AE-Rechargeable-Batteries-NH-AA-1450mah/dp/B01M4LEFVP/ref=sr_1_2?ie=UTF8&qid=1518096783&sr=8-2&keywords=usb+battery+aa ) would be a simpler fix, and no risk of damaging the mouse.

    I've always found my wireless mouse to be pretty good in terms of battery life, I think there are a lot of other household items (torchs for instance) that use batteries much quicker and so would benefit more from this kind of battery mod.

    Thanks for sharing,

    A possible upgrade for this would be a mouse pad with a charging coil in it for wireless charging. A coil in the bottom of the mouse would serve as a secondary coil. Just a thought...

    Hi! First of all, I totally agree with you! Seems a little bit risk to use 5v to charge the battery, but, to be honest, this is a cheap battery that I bought from China and in the back it says the output is 3.2v
    Since both batterys are connected in series, each one gives 1.6 v
    Then, I search information about ni-my batteries where says they charge very low, so it’s better use little amperage to avoid any risk. I’ll complement the instructable with all this information. Thank you so much for your interest

    Connect a USB cable where? The connector shown on the outside of the mouse is a barrel connector.

    HI! Actually, the usb cable which came with the controller battery, has that type of connection. I decide it will be much easier to use the same cable that already came with the package. Thanks for your question!
