I bought a second hand dsi ll (the japanese version) online, but it doesn’t come with the battery so after i bought the battery for it, the led indicator starts blinking even i with the correct model no. for the battery. So now im clueless what to do.

Hi! From Nintendo Note: If the orange recharge indicator light blinks while the system is plugged in and charging, then it is likely that the battery is not installed properly. Properly inserting the battery should resolve the issue. If you have ensured that the battery is installed properly but the orange light still blinks, check to make sure that the battery is a licensed by Nintendo. The only licensed Nintendo DSi battery will have the model number TWL-003 (Nintendo DSi) or UTL-003 (Nintendo DSi XL) and will display Nintendo’s logo. If the battery does not have the model number TWL-003 or UTL-003 then it is likely not a licensed battery.
