"My aluminum wireless keyboard had only two batteries in it. The alleged ""third battery"" was actually not a battery, although, like the previous post said, it looks very similar. Meanwhile, after struggling and banging on the battery tube, I noticed there's a little diagram on the outside of the tube with only two batteries shown. So I followed the diagram, inserted fresh AA batteries, turned it on, and it works.

I guess some keyboards have three batteries, but mine had only two.

"A couple of thoughts: Alkaline batteries leak alkaline, so baking soda (already alkaline) is not a neutralizer. Use mild white vinegar, an acid, to neutralize the alkaline. The neutralized alkaline will be a neutral salt, and still needs to be removed. Try duct taping a q-tip to a pencil. Clean carefully and thoroughly.

When alkaline batteries discharge, they swell, so don't wait until the batteries are dead to change them.

If and when the old leaky batteries can be removed, replace them with rechargeable nickel metal hydride (NIMH) batteries. They are very robust and chemically more stable than alkaline batteries. Therefore, far less likely to leak.

Good luck to all!"

"its called a lock ring too you can find in a engine repair shop. I have the tool, but the teeth were not long enough to reach the holes on the lock ring. here is an alternative

1. Get the longest screwdriver you can find, that can touch the battery and still have length showing once you put the screwdriver in the battery well. any type of tape, to tape down the wires.

2.remove plastic cover it will pop off once glue is removed. there is only 2 screws holding down the electronic board. remove the first screw, 2a, bend back slowly the soldered part that you just removed the screw from, 2b, unscrew the post.

3.there is a piece of tape the is covering the wiring lock to the circuit board. remove tape, unclip the plastic lock and pull circuit wire from the back of the board ( similar to Ipod,Iphone connection)

and push the circuit board towards the button you use to power up the keyboard. slide slowly, the battery connection is attached. once you see the connection take it off with your nail or screw driver

4.slide out circuit board, and using the some tape, tape down the circuit wire and battery wire. you can now see the lock ring.

NOTE*** be careful and be attentive to the keyboard wire as you perform the next steps

5. tape the tip of the screw driver and stick the inside the battery well.you will use the screwdrive to push up the battery. put a PLASTIC BAG over the opening, because there is a spring that will pop out.

6. using the screwdriver with one or two forceful pushes, push hard and the slip ring will give way the battery will move up towards the opening over were the plastic bag is at. if the screwdriver is not long after the battery moved up, put another old battery in the well to give you an extension.

7. slowly push keep pushing up the battery until the spring and holder pop off. now the well is open and you can push the battery back down the original way it came in. REMEMBER THE KEYBOARD WIRES CAN GET DAMAGED IF YOU KEEP PUSSHING THE BATTERY FOWARD.

8. Clean corrosion and put back parts in reverse order.

I did this on 5 keyboard and the spring never broke once while i pushed. it very thick. i tried to put a picture on this but was unable.

hope this helps you

UPDATE: for battery insertion To possibly eliminate or reduce a future battery acid leak, i put 1 pieces of duck tape around each area were the batteries touch +/-. if you put to much the batteries will not slide in the battery well. I am hoping that this will contain as much acid leak as possible should it occur again"

I used baking soda and a few drops of water and let it sit for about 15 minutes, then I forcefully banged the thing on a countertop and the batteries came out, it was thrilling. Thank you for the good advice!
