Replacement battery for PB Easynote TM90?

[philstanbridge]

I'm trying to find a replacement battery for my mum's laptop. She's got this

4GB DDR3 Memory 320 GB HDD 15.6" 16.9 hd hed lcd
Packard Bell NEW90

although she says she can't find any model numbers or anything specific to make identifying the battery easier. I have so far found a TM89 battery but I can't find anything New90. Any ideas peeps?

Are you sure it's not a 97 98 or 99 not heard of a 90? Batteries from those ranges should be identical.
