Less than 30 days since purchase, you need to exchange it where you got it.
After 30 days, you would be covered under the 3 or 5 year warranty from Logitech.
See here for RMA info.
If you are out of warranty or want to void it, you would need to find a similar Li-Ion battery and would have to solder it in. There are screws under the mouse feet.

Just fyi. A few months ago i opened my MX Revo and was very surprised. The Revo uses exactly the same Li-ion Battery as the G7 and can be swapped easily after opening the Mouse ( and very likely destroying the Mousefeets :-( ). Without any soldering.

Hi all. I searched the web trying to find out how to replace the battery in my MX Revolution mouse and I couldn't find a DIY out there so I decided to write this up to help anyone who has decreased battery life. I ended up buying a replacement battery from eBay for 17 bucks or here.
First things first. Although this worked for me, do this at your own risk. If you can't stomach taking appart your mouse then don't.
Things you will need
- Set of jeweler's screwdrivers
- Replacement battery
- Hobby razor knife
1. Locate the screw holes on the bottom of the mouse by feeling around for an in indent in the feet. Insert your razor knife into the hole and turn as you insert. You will cut a circle out to insert your philip's head screwdriver. You do not need to cut the holes too big as you will be leaving the screws in the base. Do not unscrew each screw entirely as this will force it through the feet so instead, unscrew each screw a little at a time alternating between all 4 so that the base comes off all at once. If you do not like holes in your feet, you can get replacements here.
2. Gently lift off the top of the mouse as the bottom and top are connected with a ribbon cable.
3. To remove the ribbon cable GENTLY use your flat head screwdriver to pry up each side of the black clip evenly until the ribbon releases. The first time I changed the battery out, I took care to apply even pressure and everything went as planned. When I decided to write this DIY, I didn't take the time and ended up breaking the black clip. I tried crazy glueing the tab back together but it's just too small and delicate. As a substitute, I ended up wedging a piece of business card in behind the cable after reinserting it into the connector and it works. You can opt to skip this step but the top of the mouse is awkwardly shapped and is hard to sit up as the ribbon cable is quite short. The second time around I ended up proping the top on a stapler.
4. The next step is to remove the battery retainer. Use your flat head screw driver to pry up the metal tab as it is quite flexable.
5. Remove the battery by pushing the tab forward and lifting the battery at the same time.
6. Remove the battery cage with your Philip's screw driver.
7. Using your flat head screwdriver, wiggle the connector until it comes off.
8. Reassemble in reverse order taking care when you reinsert the ribbon cable to apply even pressure across the clip or it will break. If it breaks do not frett. Use a piece of business card or anything thin and non metal to wedge it in place from behind.
Hopefully this will help anyone looking to replace their failing battery. Good luck.

BEFORE you guys buy a battery from Battery Bay or anywhere else, open up your MX revolution, to check the type battery you have, as ther are 2 kinds of MX MICE!!! I almost ordered a battery that had a cord on it, but luckily I looked inside my MX before placing an order....My MX is a little diffrent on the inside then the one you see in ` Cybersombosis` tutorial. Mine doesn`t have a cord attatched to the battery, it just has 3 contacts. ALSO, it is much easier to remove my battery, there is only one small clip holding the battery in place. So it is extreamely easy to remove!!! I think mine is a newer model. Logitech probably redisigned the mouse, because they have to replace batteries in them all the time, so now it`s very simple.
IN SHORT: If you have an older MX use the corded MX battery. http://www.batterybay.net/product-p/cs-loy11rc.htm
If you have the newer MX use the G7 mouse battery http://www.batterybay.net/Battery-for-Logitech-G7-
Also, when you take your MX apart, you do not have to cut holes in the feet to get at the screws, they are easily removeable, as they have a little glue to hold them in place, and stick back on the bottom just fine.
Thanks to Cybersombosis for your well written and detailed tutorial!
