My weird V3000 battery

This battery is weird, and bother me many times.

My using condition is: AC plugged almost all the time.

Every 3 or 5 days, it dropped to below 95%~92% and start charging. The capacity is dropped from design capacity 43200mWh to 41300mWh for less than two month, and now it even said 39010mWh for full charge capacity.

I am reading the capacity from RMClock 2.20. My Ubuntu battery meter also tell similar thing. Could this be wrong? or I really have a bad battery?

When it was 41300mAh, it can stand for >2:30 hr.

 

those batterys normally discarge like that, and they also wear like that slowly batteries lose there ability to hold energy like you stated, on my old system it was designed to have 30000mwh but when i 'retired' it it only had 20000.

there is nothing wrong with you battery.

 

I ran a full discharge using batteryeater. After a full recharge, it goes back to 39506mWh. Now the HP battery check app tells me I am 94% capacity(to design capacity I guess) and it 100% charged.

Since I didn't repeat charge/discharge when it arrived, I will redo that cycle for 2 more times and see what will I gain.

Wait for the report.

 

well... Li-ION batterys are made to be used... NOT using your battery does not prelong life. You should use it every few days... and drain it... then charge it again.

the problem is that NO MATTER what you do ... Li-ION cells deteriorate with time...

 

But that is little bit too quick. After 2 consecutive charge/discharge cycle, it is 39150mWh now. >_< #&@*!&*#!#

 

It depends on how you use it. For example, if you use the notebook on battery everyday on battery, then eventually, within probably a year, the battery will become almost useless, because it cannot retain a proper charge. The wear on the battery will go down by 2% every month, and thers just nothing you can do to stop it. If it makes no difference to th actual battery run time, then I wouldn't be too concerned.
