Why does my laptop display "replace now"?
1.The information recognized by the computer is still the old
battery, please reset the SMC.
2 The battery is not fully charged for a long time, so the battery
capacity is limited. Please refer to the solution to the previous
problem.
Why does the computer show a lower capacity (mAh) than
advertised?
Watt-hour (Wh) is the energy capacity of a battery, milliam
pere hour (mAh) is the charge capacity of a battery. The actual
voltage (V) and power (mAh) used by the computer can be
changed. Usually the energy (Wh) of the battery is relatively
constant, which is also the key to determining the performance
of the battery. In addition, the actual performance of our batter
ies is generally higher than advertised. Calculation method
The voltage is 12.26V, the battery capacity is 5400mah, and
the actual battery capacity is 12.26*5.4=66.2wh.
n a word, Wh gives a more accurate definition of the energy
stored in a battery.
