Here is another battery that Makho came up with! Follow the link below if you would like to make your own instead!
Please note that the fit will be a bit tight with the foam inside the battery compartment on an OEM shell. It is not necessary to remove this foam for installation unless you want to.
This is an assembled Game Boy Micro high capacity battery.
Battery capacity has been tested and confirmed.
This is an aftermarket product and may not fit exactly like the original. Connector my look slightly different than the original but does fit.
BATTERIES ARE DANGEROUS! DO NOT PUNCTURE OR CUT!
