A little story that I would like to share with everyone.
I have a Fujitsu U1010 3G+GPS version and it had a 2 cell, 7.2v, 2.6Ah battery.
The battery is 2 years old and could now only hold less then 30 minutes.
Official quote from Fujitsu Malaysia, RM530.
Alternative Battery recell quote, RM80
The decision to be made was obvious.
Dropped the battery off one day around noon,
next day afternoon got SMS stating that it was ready,
went to collect it the evening itself.
