Game Boy cart battery compatibility question

[Ghudda]

Just a quick question regarding batteries in GBA and GBC cartridges. I have an excess amount of CR1616 batteries (for GBA carts), but have 0 GBC CR2025 batteries. Is it possible to use CR1616 GBA batteries in GBC games (Pokemon Silver/Gold/Crystal)?

I would think that it would be alright since it's the same voltage (3v)?

They won't last as long since they're physically smaller. The numbers refer to the diameter and thickness. So a 1616 is 1.6 cm across and 1.6 mm thick, and so forth. I cram 2032 batteries instead of 2025 since they fit and will last longer.

Nice! Have a ball park estimate of about how much life you lose with 1616 vs 2025?

I'm sure this is common knowlege, but...
Keep in mind that in Pokemon Silver/Gold/Crystal, the battery is not only powering the game save but also the internal clock. I wouldn't bother with the 1616's for those particular games; I wouldn't be shocked if they didn't even last one year.

I can reaffirm that 2032's will fit in them (Pokemon S/G/C) though; it is very tight, but works.

No clue on the time since I don't play Pokemon and have only changed them for other people. But think of it like cheating by putting AAAs and lumps of foil in a remote because you didn't go buy AAs.

^hahah nice, will that actually work? I've never heard of that before, but I do agree it would be cheating on that level.

I don't do it either, but I've seen countless pictures of that sort of thing. I imagine it will work to some degree depending on the device. Remotes would probably work ok, just not as long. Something with a motor would probably be a lot less happy with that sort of cheating.

Ive not done it with AAAs, but I have done it with the insides of a 9v. In a 9v there are 6 LR61 - which are similar to quadAs. Since they typically run at 1.5v at 300 mah (just like a AA), I have jerryrigged them into remotes for short times in the past. There is little risk to the remote, unless you ground it out, but I do not recommend doing anything like that for an extended period of time.
