Alienware m11x r1 battery density dropped?

Question

Batteries

Good day to all, I ran into a problem in the form of a drop in power, as I understand it with Alienware m11x r1 / I
launched the CPUID HWMonitor program I
saw the Capacities section:
Designed Capacity: 64530mh
Full Charge Capacity: 21730 mWh
Current Capacity: 13350 mWh
As I understand it initially, upon purchase 5 years ago I should have had a value close to 64530 mWh in Full Charge.
It turns out that my battery, if you believe Full Charge, has fallen in power by 3 times?
And immediately the question, if I understood correctly, is it worth buying a new battery and updating the laptop or looking for another one?) I

Answer 1

Everyone was right about the battery.
Are you moving around with your laptop or is it on the table? It’s just that in the second case, you don’t actually need the battery at all, only if the electricity is cut. But then this is enough.

Answer 2

The battery degrades, especially quickly if the laptop is constantly charged. But even in portable models that are constantly charging and discharging in five years, the battery can sit down 2-5 times. As a rule, one or two banks fail. There are offices that repair them, but as a rule, this is no longer very budgetary in comparison with the price of such an ancient laptop assembly. There are Chinese batteries on ali, but in my experience they degrade even faster (six months or a year).
