hey so when i got my n900, i used its battery that came in the box for the first time. it got low and i put another spare battery that i had. and its been months. my spare battery doesnt give me much usage as its quite old so i decided to put in the battery that i hadn't used for months. i put it in. kept on charge for like 8 hours and the green light didnt come. the orange light was blinking like normal. so i took the charger off and used the phone and it worked for like 20 minutes after 8 hours of a full night charge. is this normal if a battery is not used for a long time? i am charging it right now and its been an hour and its charging. so how long will i get this problem? when will the battery get normal? oh and both the times that i charged this battery, when its off and i put it on charge, when i connected usb charger, it blinked a red light once on start then i took of battery and switched on phone etc and orange light came on. both the times. now its charging with the pulse yellow light
