TWL-003 Battery, (2025 New Version) 2500mAh Ultra High Capacity Li-ion Battery Replacement for Nintendo DSi, NDSi Game Console, with Repair Tool Kit (Not for Nintendo DSi XL, DSi LL, DS Lite)

Revived my old DSLite. Now I can leave it running for over 3 days in a game without dying. Absolutely insane how much better this is than my original battery!

Just needs to be calibrated first 1) Charge the device to 100% and leave it charging for another one or two hours, without using it. 2) Disconnect the charger and use the device normally, until it reaches 0% and turns off. 3) Charge it again to 100% This should solve the issues others are stating they're having with the battery not lasting long.

4 stars for only a mildly inconvenient reason, the battery lasts a long time, my DSi XL has been sitting in standby with Zelda running for over 3 days now and hasn't cracked 80% battery, so the battery itself is great, it is approx 1mm shorter than the original and as such does not fit snuggly inside of the battery bag. It won't charge unless you make a shim, I basically layered 3 pieces of scotch tape on the butt end of the battery and it worked perfectly.

DSi was having problems where if I unlatched the lid hinge, the whole system would turn off. Switched out the battery and hasn't happened since.

Fake bought 3 of these and not a single one as advertised and 1 has already failed and hardly keeps a charge. Dont buy this garbage.

Excellent

Aumenta bastante el tiempo de duración dela bateria comparación a la original

Works and fits DSi perfectly

Es verdad lo que dicen otras reseñas, la batería es ligeramente más pequeña que la original, así que hará falta un pequeño trozo de cinta o papel doblando varias veces para que se fije bien, fuera de eso, funciona muy bien, seguí los pasos indicados de su uso (descargar la batería completamente 3 veces y luego una carga completa) y sirve de maravilla, me sorprende lo mucho que dura la batería, van ya unas semanas y todo bien. Por último, mejor un destornillador aparte, el que viene incluido con la batería va a terminar barriendo el tornillos, pero bueno, realmente es un extra.
