Fulll charge capacity is higher than design capacity

[Dannychaw]

Okay. So i have a hp notebook with battery design capacity at 36480mwh. And initial full  charge capacity when i checked it after.some use was 35990mwh with 2 cycle count out of 1000 cycles. After some software  updates, the full charge capacity jumped to 39560mwh, it flunctuatuate between this value to 40163mwr. After i followed an instruction and drained my battery to recaliberate it, i recharged it and the full charge capacity read 29910mwh (19% wear) for 20 cycle/1000 cycles. Soon after again, not more than a day, the battery full vharge capacity jumoed back to 39950. I tried draining the battery to jusy 20 percent again aboiding initial kind of deep drain. After i recharged it  fully again, the.battery capacity did not change. 

My questions are, what else can i do to recaliberate my battery (i have used hp hardware diagnostic tools. I have done both  fast and extensive test without any resolve)

Secondly, if my real battery full charge capacity is at 29910 (19 wear level) with just only 20 charge cycle. Shouldn't  i be worried that the battery is bad. Because it means at 100 percent charge cycle, my battery wear would be 100 percent.

"After i followed an instruction"

I don't know what "instruction" you followed, but it gave you bad advice.

Since you stated that you fully drained the battery I must tell you that you are lucky that it is still working.

The lowest I would ever consider draining a laptop battery would be to twenty percent. On rare occasions, I have inadvertently let the capacity fall to ten percent.

A full drain of a lithium ion battery cones with the risk of the Battery Management chip on the system board  putting the battery in a fail  or sealed condition. 

If that happens, the battery will not charge at all.

When the full remaining capacity will no longer go above perhaps seventy percent, you should consider replacing the battery.

After you replace it, this time leave it alone and use your laptop normally.

Yeah. Anyways i am not so sure it drained to 0 percent. But i am sure of 10 percent. Because it was during extensive test this happened. I allowed it drain during extensiive test it drained off. But the system was still set to power off at 10 percent.  However. The battery still works well for solid 4 hours. But if you suggest i just leave it. I have no much option. As far the battery is serving well.

Yes.

I recommend that you leave it be and use the laptop as normal.
