Ok so my Nokia Battery Got Wet...

Just back from holidays, long story short I was by the pool & my N97 slipped outta my hand...life flashed before my eyes as the phone hit the ground & broke into the 3 main pieces...the front main part, the back cover & of course the battery.
The first 2 skidded a bit but thankfully stopped on the ground before goin into the pool.
The battery however skidded onto like a little lowered part of the pool surround & was immersed in water for about 5secs before I whipped it out.
Dried off the front & back parts of the phone just in case any moisture had got near it but they werent wet thankfully....then the battery I dried off thoroughly too for about 10mins, making sure to dry the connectors especially.
Stuck it back in the phone, switched it on & its been grand ever since.
Just afraid there might be some long term damage or anything I could expect???
