Mars Devices Replacement Battery for New Nintendo 3DS XL and 3DS XL Models SPR-003

I bought a restored 3DS from one of those game stores, however they did not tell me the battery was not doing well. I bought this product, took less then a minute to put in the replacement and after a couple hours charge, my 3ds is behaving like it it brand new.

Super easy to install. I like that it came with the small screwdriver necessary to install into 3DS. It's worked for months now with no issues.

got a smaller battery at first, but ended up with a larger one than what I ordered on the second try, works great one month in.

Like it says, it is a working replacement battery for the new 3dsxl. Works very well

Everything works great and shipped quick.

Fits great & easy to swap out but holds a fraction of a charge compared to OEM. I want to return it but seller does not cover return shipping, which makes it pointless as refund amount would barely cover it. Very dissatisfied.

The battery I received didn’t look like the pictures and had 250 less mAh.

I used it to replace my dying 3DS battery. New one in, works like a charm.
