Open "cmd" as administrator & type

powercfg /batteryreport

Then see/find and calculate

Battery health = (Full charge capacity/design capacity)

ex.

Design capacity: 41,440 Full charge capacity: 27,942

Battery health = 27,942/41,440 = 0.67427.... That mean your battery have 67% health from actual 100% health.

Some Minimum Requirement

Check ram speed using cmd

wmic memorychip get devicelocator, speed

This cmd will return all your ram and their speed

A quick calculation when buy ram.

cal = (cas latency/speed) 
    = (15/2133)
    = 0.007032.....
    = 0.007032..... * 2000 (optional calculation)
    = 14.064.....

So, the result the lower the better
