S2 removable battery in a DMG-01Show
So, is there any other battery we could use? Something that may fit even better? It would be nice to a) find a battery that fits and b) find one that has a "large" aftermarket version with 3000 mAh and more. I'll use this thread to collect battery dimensions and if anyone is willing to help or measure their own smartphone batteries, it's very welcome.
Gameboy DMG-01 Battery Cartridge Dimensions
It's by far harder to add a longer battery (first value) than a wide battery (second value). The long (~6 cm) S2 battery needs you to shave off parts of the GB shell, whereas you'd only need to cut off parts when adding a wide battery.
5,75 cm x 5,02 cm x 1,14 cm (default)
5,85 cm x 5,58 cm x 1,38 cm (max)
Battery dimensions
The dimensions are first results and should be rechecked. I also didn't check (yet) whether there's huge versions.
Probably a perfect fit:
5.8 cm x 4.3 cm x 0.5 cm - Galaxy Ace
5.7 cm x 4.3 cm x 0.5 cm - Galaxy Ace 2
Might fit with alterations to the case:
5.8 cm x 5.1 cm x 0.6 cm - LG Optimus 4x
6.0 cm x 4.5 cm x 0.5 cm - Galaxy S2 (tested)
6.0 cm x 5.0 cm x 0.4 cm - Galaxy Ace 3
6.0 cm x 5.0 cm x 0.4 cm - Galaxy S3 Mini
Doesn't fit:
6.320 cm x 5.008 cm x 0.441 cm - Galaxy S3
7.1 cm x 5.1 cm x 0.4 cm - Galaxy Ace 4
