capacity of the unit, its Chinese name is mAh. Purchases in general,
many of my friends might think mAh battery unit will have a big longer

so, the laptop battery can often see "6-core 4400mAh", "4 core 2200mAh"
battery nominal value such as the passage of time we believe that

its Chinese name "Wh." Of course, "Wh" and the
"mAh" is a close relationship with the following formula: Wh ÷ V × 1000 =
mAh be noted that the measurement of electrical power consumption of
the unit itself should be a power, that is, "Watt."
Since then, we can learn
to select the notebook when the battery is not where it should be noted
"mAh" but "Wh" and the voltage of a few. For example to speak, is
also a 4800mAh lithium-ion battery voltage at 10.8V and 11.1V under
different out of life embodied in the ability different, and this
different from the "Wh" different. By calculating we can get
the following equation:
4800 ÷ 1000 × 10.8 =
51.84 (Wh)
4800 ÷ 1000 × 11.1 =
53.28 (Wh)
It is obvious to see that

First
to look at books from the perspective of saving the battery, as to
energy conservation, it is necessary to first know how to avoid cell
"aging"! Typically, the battery internal resistance with the use of
time as the growth becomes larger and larger, there will be voltage
drop mate, system voltage support is not sufficient, resulting in
severe shortage of electricity. Over time this will be a vicious
circle, seriously affect the battery life books. This was lucky,
sometimes your books battery failure will be a failure in a very short

it will result in the overall series, voltage delay, regarding the
scrap it! Therefore, to use electricity during charging, do not use

While
the battery is a consumable, lithium-ion battery is no exception. But
no one wants to use up the battery fine spirit of God, to what age do
not even rattle is finished, no one wants to start his own half dead
battery does not pull the living, has been rubbing on it in 2023, makes
good sad to realize how the thing about you is not?
Well, get down to business, following the battery began to speak. First explain, only lithium-ion battery HP Laptop Battery.
Appropriate charge and discharge current
General
literature and the state standard on lithium-ion batteries on said
lithium-ion battery charge current should be between 0.2C to 1C. It is
said that the charge current battery capacity, such as your battery is
4AH, then the 0.2C charge current is 0.2X4 = 0.8A, that is the charge
current should be between 0.8 to 4A. In general, the charge current at
the extent permitted by the smaller the better, rechargeable
lithium-ion battery should be a constant current charging the start, in
my IBM R31, this current is about 2.8A, equivalent to 0.7C, is charging
its own circuit control can not set yourself. Although this indicator
does not charge more than the standard requirement, but is actually
relatively large, especially when the battery capacity decline for some
time after the charge current may be more than 1C. Now the length of
time charge notebook users have also become targets regardless of the
manufacturers were forced to set such a high charge current.
So
first step is to reduce the charge current. I have a friend in the lab,
all equipment readily available, on trial with him a bit. Power outlet
on the first series resistance try a result, current is reduced, but
became intermittent charge, this is not a good thing. Through trial and
error, 4 Ohm is a more ideal value, this time around 0.8A charge
current is very stable. This is only the current flowing through the
machine power connector, battery charge current is estimated to larger,
should be slightly larger than 0.2C. Specific to a different machine,
this value may be different. Also with the increase in battery voltage,
charge current will be reduced, but the decrease rate is small, less
than 0.05A. In this charge state, charging circuit seems to not work,
the battery indicator light is not bright. Etc. After the battery
voltage up to 12.6V, charging circuits came into play and trickle
charge the battery into the state, this time does not matter whether
the series resistance has been, the charge current is controlled by the
charging circuit, the last full charge after the charging circuit
automatically end. The charging time is about 5.5 hours, if not
resistance, charging time is 3.5 hours or so.
Lithium ion
batteries are very delicate, good charge control circuit is required.
With this charging method, can reduce the charge current, battery life,
while use of the books original charging circuit controls the charge is
relatively simple to achieve them, just buy a power plug (that is, from
the power supply plug into the notebook kind, the best to buy two,
followed by the methods referred to still use one, be of good quality)
and a resistor on it, pay attention to big head and little resistance,
after all the above are about 2W of power Otherwise, it would be more
heat resistance, preferably constant resistance of the wire myself one
of the wire resistance and this resistance is independent of
temperature. However, this disadvantage is also obvious that, while not
charging work with books. In addition, when charging will have a
strange phenomenon, I do not write omitted here, and you try to know,
Fortunately, this phenomenon into the trickle charge after the state
disappeared. To extend the charging time is not a big problem, anyway,
before the night began to charge the next day wake up and fully
charged, of course, if you are a night owl or a special short sleep
time, that is another matter.
Small current charging problem
solved, and now discharge problem. In fact, this is difficult, after
all, the book is used to work, the discharge current will vary with the
working state, the method mentioned here only designed to restore
battery capacity of the operation.
Start the machine, set the
power management will never go to sleep (standby) and hibernation
(hibernate), others are set to the most power-saving mode, including
CPU speed, turn off hard disks, turn off displays, while in TP
management process Close some unused hardware, such as sound cards,
etc., and then open the battery status display window, and allowed to
run in the foreground! ! ! Close other programs, in particular, screen
savers and other programs that run on time! ! Do not use the machine,
do not close the lid, let the battery discharge end (not to discharge
the minimum value set to 0, I set up 3%). Display and hard drive shut
down, the discharge current is about 0.5A, this is my IBM R31 can be
achieved on the minimum discharge current, battery LG Laptop Battery
discharge to the minimum value of the machine will automatically shut
down after. The discharge lasted for more than four hours, depending on
your battery capacity may be different in different, this time is also
used to sleep way to send the.
Well, the last to emphasize
that the method is not dead, especially discharge, 10 times which can
be done once, or else why should the battery? Charge all the best with
a small current charge, of course, if the need to use batteries, power
cord plugged directly into the notebook on it.
Using this
method my battery is now fully up 14 times, the capacity has been
maintained in 45 more, the battery design capacity is 43.2, and has
come down, but after such a charge and discharge are restored.
Beginning
about two points, one appropriate charge and discharge, and second, not
to discharge less than the charge, discharge less than the following to
see how to solve the problem on the charge it:
To minimize the discharge less than the charge or over discharge
In fact, over-discharge a good solution, not to terminate the discharge limits set too low on it, I have been using 3% LENOVO Laptop Battery.
Often
use batteries may only be a short Shi Jian, such as battery remaining
70%, if the switching power supply, then the battery will Zidong
charge, such a loop vanishes, although the battery's Shoumingbushi set
to cycle the absolute number of death of, but always it will reduce the
battery capacity, lithium-ion batteries have no memory effect reported,
but in fact only a relatively low Bale memory effect. Unfortunately,
IBM does not provide solutions to discharge less than the charging
method, but provides the basis to solve this problem. This is what I
found on the R31 may not be suitable for other machines, but the method
should also not far off, do not forget after you've tried were posted
for all to share.
R31 charging circuit based on the status of
the power to decide whether to charge the battery. Power supply output
voltage is 16V, within error of plus or minus 0.2V, if the voltage is
lower than 15.5V, so not to charge the battery charging circuit, and
books can also work, this is the IBM provided the basis for settlement.
But the foundation is weak, because the voltage, if less than 15.2V,
books will be converted to battery power, even if the power outlet in
the books are useless. In other words, we can torment the space is
0.3V.
If you can find a 15.5V, over current 3A switching
power supply, then the problem is solved, otherwise please continue to
look down IBM Laptop BatterySONY Laptop Battery.
Reduce
the power supply output voltage 0.5V is not an easy thing, series
resistance does not work, because the resistance of the voltage will
change with the current size. I use silicon rectifier diodes, to allow
more than through the current in the 2A, or hot tube. Silicon Rectifier
diode forward voltage drop between 0.7 to 0.5V, just to meet the
requirements. Now a plenty of such tubes in the electronics market,
price less than 2 yuan. To a different book on the specific situation
may be different, the best time to install a digital multimeter Cece
hand. Pipe is being connected serially in the power output, and still
harder to buy a power plug inserted himself in the notebook. Diode
which is not reversed, the book does not work it wants, and then in
turn connected on it.
In this way, the power output voltage
drop is about 0.5V, if the drop too much, the book will switch to
battery, if the drop too low, the book will charge the battery, the
specific number to you in your own notebook tried to know.
We
all know that the battery will not charge if the impact would be very
time of their life and the use of, then how can the effectiveness of
the right to play their best then? Let me show A thin thin for everyone Tao Road to - a very thin very thin (imagine the echo effect of your own ^ ^)
Some
equipped with lithium-ion laptop batteries using the battery system
such as SBS intelligence technology to accurately measure the battery
life, so use of some peace of mind. Although
there are many advantages of lithium-ion batteries, but battery life,
the power supply last longer, need to master some professional charge
method. Laptop Battery camera camcorder batteryTOSHIBA Laptop Battery ACER Laptop Battery Bought
a new lithium-ion batteries used for the first time, the need for 3
full charge and discharge, that battery fully charged at least once a
power, then power up to do, repeat three times before use. To
activate the chemicals inside the battery, the electrochemical reaction
inside the battery into the best in the future can be freely used in
the charge that is used, but within a month to ensure the battery must
be a complete discharge, so depth of discharge can stimulate cell activation performance, battery life plays a key role. If
more than 3 months the battery is not used again until the same should
also be carried out with a new battery charge and discharge completely
3 times to ensure that activate the batteryACER travelmate 4600 batteryDell INSPIRON 6000 battery.
The
use of nickel-metal hydride batteries, which must control the charge
time, should be careful not to over-charge frequently, otherwise it
will shorten the battery life. In
addition, the NiMH battery be fully discharged before charging, the
charging should be fully charged before use and in the normal, also
requires the completion of 3 full charge and discharge ACER aspire 5560 batteryACER BATBL50L6 battery.
Most
users used each time when using a laptop, plug the AC power supply are
very rarely use the battery to the notebook computer power supply. In
fact, every month should be at least one or two batteries to power, the
battery completely run out, connect the AC full-time. Remember
this one, for charging batteries will run out again full of power,
useful and harmless, because the notebook computer lithium-ion
batteries used in certain inertia effect for a long time without loss
of activity of lithium ion would need to re-activation APPLE M8403 battery ACER aspire 3000 battery. When the notebook computer using AC power when the room is best to remove the battery so it often is in charge state. Best off when charging laptop, the battery can be fully charged, do not disconnect the power in the charge halfway. Fully charged, should be used within 30 minutes.
In
addition, because the battery is easy to run out of power, most of the
notebook computer has only one battery, thus, part of the document so
that computer manufacturers developed a fast charge feature that allows
users to reduce power consumption and the fastest speed available after
the additional power . For example, Dell's notebook computer will have ExpressCharge feature, you can recharge in one hour more than 90%. Why
not 100%? Because according to the charge and discharge characteristics
of lithium batteries, if often charged up to 100%, the battery life on
the big shortened notice, so 10% will be back before the slow-fast
charge to charge to extend battery Dell INSPIRON 6400 BatteryDell INSPIRON 9400 Batterylife.
No
such function for ordinary laptops, the best way is to charge off,
charge off charge will be 30% shorter than the boot over the charging
time.
The
new notebooks in the first boot, the battery itself should be 3% of the
electricity (which is also common practice firms. If you first open the
notebook to buy and found that the battery is full, is certainly used
by others, a). At
this point, you should be the battery exhausted, until the shutdown,
and then use an external power charger, charging time must be more than
12 hours, repeated three times, so as to activate the battery
completely, can effectively improve the battery SHARP Camera BatterySONY Camera Battery life.
Second, to reduce the number of battery
To
minimize the number of battery, this method seems to be some people
feel uncomfortable, since bought a battery is not so frequently used,
it bought Zuoshen. Having
said that, but the number of battery charge and discharge directly to
the life of a single battery charge, battery on a step forward to
aging. Suggest that you use an external power supply, use an external power supply when the battery removed. Some
friends of convenience, often several times a day plug in the power
supply, and laptop computers equipped with a battery, do more damage to
the battery PANASONIC Camera BatterySAMSUNG Camera Battery. Because
each time access is equivalent to an external power supply to charge
the battery once the battery life naturally shortens the number.

after charge Yong Jin and avoid charging time is too long, regardless
of your notebook to use nickel-metal hydride or lithium electricity, be
sure to fully charge after Yong Jin (power less than 1%), which is the
best way to avoid the memory effect . No memory effect on lithium argument, I note in front of businesses irresponsible been misled. Lithium also have memory effect, but it is the memory effect than Ni-MH small number of Bale. And
battery charging in the same way, when you charge the battery to the
laptop, try to avoid too long, the general control within 12 hours. As
for the prevention of exposure to prevent damp to prevent the erosion
of chemical liquids, avoid contact with the battery contacts and metal
objects such as notes, not much to mention here also.
If
you do not use the term laptop batteries, should be conducted each
month on a full battery charge and discharge, in order to maintain cell
viability. Also,
if long-term (over the year) does not use the laptop battery should be
charged to 50%, and once a year charge, in order to prevent excessive
battery discharge. Charging time may be more effective if the shutdown, but does not require to be shut down.
