Great guide. Thanks.

I keep wonder why all these flash card makers and fake cartridge makers can't make one with easily replaceable batteries (like clocks)...

Did you know that you can charge the battery by leaving it inside the unit (DS) when it is recharching ?

incorrect, this 3in1 battery is not a rechargeable battery by any means. the slot2 does not receive power while charging.

The battery in the 3in1 and other slot2 cards charge up while the DS is turned on... and you madam, are an idiot.

I'm pretty sure the 3in1 doesn't have a rechargeable battery, either way.

Excellent guide! However, I was wondering if it would be possible to attach the battery with some sort of (super) glue, instead of electrical tape?!

Well, electrical tape is probably your best option one way or another. I don't think super glue likes gluing metal to metal. Anyway, with this method, it's easy to take it apart again. If you're using glue, you might as well just solder it on again.

Yeah, you're probably right. Maybe I should just get one with soldering tabs and try to solder it in. I was just thinking about this, because I want to change the battery of some of my GBC games and all this electrical tape would look kind of strange in a clear case. Anyways, thank you!

i'm an idiot for making a correct statement based on fact? also how do you figure that a non-rechargeable battery can be recharged via a slot that is not receiving power when not in use? have you ever tried to recharge a non-rechargeable battery? its fun when they explode.

try reading a bit on the ez flash forum, where the speculation about a mythological rechargeable 3in1 kit was put to rest.

I used this guide to replace my battery, and it seemed to go well without problems. The tabs remained intact and I manged to wrap three strips of electrical tape around the battery to secure a good connection. However, even with the new battery my GBA games are saying "Save Failed".

My only guess is that I used a CR1225 3v to replace the original CR1220 3v. What's the difference between CR1220 and CR1225?

Can someone give me a link to a site that ships this battery worldwide?

RadioShack search engine sucks, it just leads to a bunch of pdf files about safety

Ya i kinda messed mine up i broke the contacts off the PCB. I was able to fix it with a gentle touch, a little wire, and some solder. Here's a view of my screwed up version. Note the blue wires LOL. Oh well, it works tho, thanks for posting the guide!

Here is a link to the radioshack site and the battery. I picked mine up at the store tho not sure about shipping.
