In early 2017, I replaced it with a 9-cell battery.
Recently, nomad’s battery started behaving oddly.
Yesterday, I noticed that charging would stall at about 80%. Upon recharging it later, acpi told me its “last full capacity” was 69% (down from 87%). This morning, battery life suddenly jumped from the low 20s to 5%.
I may try reconditioning it to see what happens.
