Hacking DSi - DSlite battery

[Nitro Edd]

are the DSi and DS lite batteries interchangeable? I doubt if they could, but could I see a side-by-side pic if you don't mind?

I want to know why because my DS lite charging port finally broke after a few weeks without its tongue, so now it's 'un-chargeable', still works but you can't charge it. so I am going to buy a new system most likely a DSi and I wondered if I could charge the battery in one then swap.

EDIT: my DSlite hinge is broken and the mic doesnt work, needs a replacement.

Nope, DSi has a different battery and a different charger port.
