DSi Battery, TWL-003 2500mAh Replacement Battery for Nintendo DSi, NDSi Game Player with Repair Tool Kit (Not for Nintendo DSi XL DSi LL DS Lite)

This is a inexpensive means of replacing your likely tired battery for your Nintendo DSi handheld console, which could be potentially 16 years old. It's a very straightforward exchange too, with just two tiny screws to remove to get at the battery bay. You get the correct sized screwdriver included within the kit.Do be very clear that this is for the later Nintendo DSi model, not the original DS or DS Lite, or even the DSi XL. Those have wider, shorter batteries that will not be compatible with this battery.My test period is too short to assess the longevity of the battery so I can only wait and see how well the battery lasts.
