battery problem

hi i m new user from india
i bought my sony prs 505in nov 2008
since then chargeing it with the usb till feb the battery life was good then i started charging it with a local wall charger its details are-

CC-CV CHARGER( CONSTANT CURRENT - CONSTANT VOLTAGE CHARGER)
INPUT- 100-300~47/53Hz
OUTPUT- 5.0VDC-1.0A CC/CV

Since then battery performance has decreased gradually,
now it gives hardly 500 pages turns, n gets drained if idle for 2 days.

is the problem with the charger or the battery needs to be changed.

i have this option of battery
NOKIA BL-5CA, Li-ion BATTERY, 700mAh, 3.7 V

WITH CHARGER

NOKIA AC-3E,
INPUT-AC 100-240V/ 50-60Hz/65mA
OUTPUT- DC 5V/350mA

IF NOT then please suggest any good battery and charger but it should be nokia as i ve opened the case and i am sure any nokia phone battery will fit in it.

IMP- FROM THE BATTERY THERE ARE ONLY TWO WIRES GOING INTO THE UNIT (black and red) but in nokia phone battery there are three connections

please help
