The battery came on time and it was somewhat easy to install (took some figuring out) but once it was installed, it was amazing and I'm able to use my 3DS for long periods of time without the need of charging it.

I have this battery for great long Play time.


Big and Awesome

The battery is great! Easily get a weeks worth of always on (sleep mode) and casual gaming everyday (I personally play 3DS games and NO 3D usually). Sure is nice not to have to plugin every other day anymore!

She is a beast! 3DS XL was already large, so be prepared to carry around a brick, but IMO well worth it.

So far the only down side is the new battery cover has been losing some of its blue color and see white plastic underneath due to normal wear and tear on the underside of the handheld.

I went from charging my 3DS once every day or every other day to now only charging it once every seven or eight days!

Well worth the price!


Works remarquably

Great product. Great communication.


All that and a bag of chips

This product is solid the battery life is great. I no longer feel tied to a power outlet and I don't have to worry about leaving the unit open.

The battery cover is solid and very comfortable for larger hands. The plastic does not feel flimsy and it attaches to the unit snugly.

If your worried about weight it's there but hardly worth the mention. Use 2 hands and you will not notice. The battery life is the real star here a bit high for a battery and cover but honestly I would buy it again.
