My pokemon silver won't save anymore, I got all of my stuff deleted

I heard from a friend that this is because the battery in the game is going bad

how would I replace this?

It is possible to fix this, but the cartridge must be opened and the battery must be taken out, and a new battery must be soldered in. The battery model is model CR2025, although a larger CR2032 fits as well and will last longer. An inexpensive replacement battery can be purchased with the same welded tabs and insulating ring already attached such as the Panasonic BSG series (part # BR2032-1F2) available from Digikey. One will need to be able to use a soldering iron to remove the old battery and install the new one. One should get a battery with welded tabs such as the one mentioned above; it is difficult and unsafe to solder directly to a lithium battery without tabs.

*From a Wiki somewhere*

It was like the second thread in a Google search. Is it really that hard to search with Google?

It is possible to just solder a new battery in, but they don't take solder very well at all. It's so worth it to just buy the ones with the tabs on them.

Whenever I replace batteries, I always use the 2032. I don't like messing around with it, so I prefer the longer life.

Unless you have a really powerful soldering iron, I wouldn't try soldering your own tabs on to a new battery. I think my iron was 30 watts, and I wasn't able to get anything to stick. I ruined the first battery I tried soldering to because it heated up too much, bulged a little, and lost its charge. As I explained in the page hailrazer referenced, I just ended up making a spot welder.

spot-welding is supposed to work to put the tabs back on. or since the space is so tight, I just used some electrical tape

ok, do I need the insulation ring? or is it optional

would this battery work?

If you do not have the insulating ring, you can use tape to prevent the tabs from shorting the two halves of the battery together.

No, that battery will not work. The tabs need to point in opposite directions.

This would work.

is 10000 micro farads enough for the spot welder? I got it out of an old computer power supply.

I've never done it, just something I read about. I'm pretty sure they made a spot-welder out of an old disposable camera, so I'd assume something from a PSU would probably do the trick.

Here is how I made a spot welder.

Making an Arc Welder to Attach Tabs to a Battery

If you don't want to spend a load of extra money buying batteries with tabs, you can build an spot welding device. This will work much better in attaching tabs to your new battery than trying to solder it.

You can reuse the tabs from the old battery by gently prying them off. I have heard that using a knife blade works well since it can slide between the battery and tab without bending it out of shape.

If you have a disposable camera (or any kind with a flash that you won't mind taking apart), you can open it up and make your own welder.

*Find the capacitor inside that stores the charge to power the flash.
*Attach a wire to each lead of the capacitor.
*Use an insulated tool such as pliers to hold the tab in place. If it isn't held down, the spark may make it fly off the battery.
*Once the capacitor is charged up, place one wire touching the edge where the tab meets the top of the battery.
*Touch the second wire to another point where the tab touches the battery.
*Remove both wires.

When the second wire makes contact, a spark jumps between both wires, melting the spots where each wire touched the metal. This allows you to fuse the tab to the battery. If you practice this, you can get it to work. Sometimes you get a stronger hold than others, so make sure you fuse multiple areas where the tab touches the battery.
