Default Is this a battery problem?

Hi at all! My 3DS fell into water long time ago. Now, I decided to try if I could fix it. I tried to wire a cellphone battery to the 3DS: it turns on, but few seconds later, when the bottom screen tries to light up, a popping sound appear and all shuts down.
This is what I have done:

These are the battery specs:

3DS Stock Battery:
Voltage: 3.7V
Capacity: 1300 mAh
Wattage per hour: 5Wh

Cellphone battery I tried:
Voltage: 3.7V
Capacity: 2000 mAh
Wattage per hour: 7.4Wh

Also, the cellphone from which I picked out the battery fell into water, and all I had to do is to buy a new battery. Maybe it don't work because the 3DS's one have a special circuit... I don't know...
So, it could be a battery problem? If I buy a new battery, could the 3DS work?
Thanks in advance!

It looks like your 3DS isn't completely dead but you should get a battery specifically for use in a 3DS.

Not sure where you live but the official Nintendo US store sells a replacement battery for only $15. Link here

I wouldn't mess with it anymore until after you get that battery comes in. If it still messes up after you put in the new battery, I would contact Nintendo and they should be able to transfer your old data into a new device.

I had my 3DS survive falling into water. I just let it dry out for several days.
It says in the instruction manual you should only use batteries from Nintendo so I'm not surprised your (rather creative) solution didn't work.
Yes, I am a Janus. Yes, I figured that out myself.
