my >NEW< Monster Hunter 4 3DS XL needs a new bettery. this one says 2000mAh, where as the one in my 3ds says 1750. Will this battery work and not cause damage?

The mAH number is just how long the battery lasts. You can use any capacity battery and it will work fine. That being said, I do not recommend this brand. Both the original and the replacement I got when I complained to them only last about 5 hours of active playtime.

can you buy this item in the store or do you have to order it from the website?

i don't know. the one i got here still only lasts 5 minutes. :( either DS is broken or this one is also bad
