Laptop battery question

lundi 8 octobre 2018

My poor student daughter is reporting her 6 month old HP Pavilion is losing charge very rapidly. She did a battery health check and got the following diagnostics.

She says she has managed the battery responsibly (not leaving it constantly plugged in). She phoned Curry's for support and they said it wasn't registered so they couldn't help.

I can see that it's lost about 15% of its maximum capacity, which seems a bit poor for 6 months with a perfectly reasonable number of cycles (137 vs design life of 1000), but doesn't explain very reduced battery life in practice.

Also what is "PrimaryCellVoltage4: 0mV"

Is that capacity or charge? Do the cells discharge together or one after another?

Could this be a fault?
