OSTENT 2000mAh Li-ion Battery Rechargeable Lithium-ion + Tool Pack Kit for Nintendo NDSi LL NDSi XL Console

When it first arrived I was only getting about an hour to a charge but the more cycles I put it through the longer it's lasting. Now I'm getting a little less than four.

It's just a smidge too short and doesn't make proper contact with the pins. Solution: fold a small piece of torn paper a few times to make a spacer to snug it in.

A gift.

I don’t usually write reviews but I am writing this review as I did not bother asking for a refund as I was too lazy to hassle over a 11$ item. The obviously used battery on the left is the battery I got that was supposedly brand new. I ordered a new ostent 2000mah battery and got a used 1050mah nintendo one instead. On the right is my old nintendo battery that I was replacing as it started bulging and failed to work, and as you can see, there is a noticeable difference and my old one looks more new than the supposedly new one. It does work, don’t know for how long, but it does work so I’ll be using it for the time being but just be aware that this happened to me

It lasted for about 5 minutes before my ds started blinking again, this was a complete waste of money

I got a used, completely dead battery. Reads 0V as shown in picture and is not even the 2000 mAH stated. The battery says 1050mAH on it!. Same thing has happened to another reviewer. Seems like a scam.

Despite charging this battery for hours, it would not hold a charge when used in our Nintendo gaming system. Returned immediately.

This item arrived defective, the battery fully charged lasted 5 min approx....
