We usually see Laptop Batteryhas
two ratings: voltage and milliamp-hours. The voltage is short-circuited
for V, and the milliampere-hour is short-circuited for mAh. Voltage,
the rate is taken with the energy from a battery. MA-hour, the capacity
of the battery.
The milliamp-hour rating is the capacity of the
battery. Capacity is affected by the number of batteries in the battery
pack. The capacitance is in parallel by connecting the cells. If the mAh
rating is higher than the original laptop battery, then the replacement laptop battery for longer run time, if the rating is lower than the replacement battery will run for a shorter time.
If
you buy a new battery for your laptop, you must select a battery with
the same power rating with the original battery. The voltage should be
chosen such that correspond to the original battery or as recommended by
the manufacturer.
Different battery chemistries can not be
replaced unless the laptop was in the factory to accept more than one
type of battery can be configured. Read your laptop manual to find out
which accepts laptop battery types your device.
The small LED
lights on the laptop battery This battery is like a fuel gauge. It tells
the relative amount of capacity in the battery. An LED light would mean
that the battery is nearly empty, when all the LEDs then it would mean
that the battery light to full capacity.
You can also listen to
smart battery, and you know what the smart battery? Smart batteries have
internal circuit boards with smart chips that can communicate with the
notebook and monitor battery power, voltage and temperature. Smart
batteries give the computer much more accurate "fuel gauge" capabilities
to determine how much battery time is left before the next recharge is
required.
