Aspire A715-71G-55KS, 3 year old
It happened twice in a 40-day timespan, I had disconnected the charger for a few minutes, reconnected and then it would continuously start and stop charging every ~10 seconds at ~93% charged. I tried rebooting, power resetting with battery pin, nothing worked, I left the laptop with disconnected charger overnight, and in the morning it would charge to 100% without any problems.
Today, I attempted a discharge cycle, continuously discharging the battery at ~30 watt, and at about 40% battery left, the laptop shut off instantly. I reconnected the charger, it powered on and charged normally until it reached about 70% where the previous start-and stop charging problem reappeared. After a while the battery stopped charging and now the charging light blinks orange every second.
I think that it is safe to conclude that the battery is bad and needs replacing, right?
I would like to request information about replacing the battery procedure, what's the battery model/part number and where I can order it. Thanks.

I am pretty sure it was the battery LED. The power became blue as soon as I powered on the laptop, then I connected the charger and the other light started blinking.
The capacity/life changed as well, it was 100% and the energy reported was 49 wh, and in the morning it was 87.3 % with 42.3 wh when full. Maybe it was due to calibrating-something.
