Macbook Battery

[bmms8]

Hello i have a C2D white macbook and sometimes when i am not home i dont use my macbook for 24-48 hours and when i do turn it back on, i notice that my battery loses a little bit of charge. I have it plugged it all the time when i am using it and unplug it when i turn it off. when i come back to it a day or two later it says it needs to be charged for about 20 minutes for it to be charged again. do i have a faulty battery or something? istatpro shows me 95% health 40 cycles, 98% charge and 28 minutes til fully charged. thanks in advance!

Have you calibrated your battery?

Batteries loses charge over time. There's nothing wrong with oyur battery. The fact you left it off for about 2 days then using it again, its normal to lose a few percentage charge.
