New battery and only charge to 45%?


My new battery cam with an eight page manual containing instructions got use in a translated (poorly) version of the Chinese original. Of course I did not need a manual to install a new battery and ran into the same problem as you. Refer to the discarded manual and find one and a half pages on how to initialize a new battery.

"User Manual on Laptop Battery

Respected users:
Thank you very much for trusting and using our laptop battery. Before using the battery, read this manual carefully. This instruction manual elaborates how to use and maintain the battery correctly. Batteries are consumables, and have a limited service life. However, we can prolong the life of the laptop battery considerably through correct operation, proper charging/discharging and correct storage.
Calibrate your laptop battery to optimize its performance
Inside the laptop battery is microprocessor software, which calculates the battery volume during the charging/discharging. Batteries must be calibrated from time to time to ensure correctness of the time and the percentage displayed on the screen. You must implement a complete cycle of charging and discharging the battery at the beginning of using the computer, and repeat this cycle every two or three months. The charging and discharging procedure is as follows:
1.Set the Power Supply option first: Right click on the screen and select Property -> Screen Saver -> Power Supply -> Power Use Scheme -> Portable. In all the subsequent operations such as When Computer and Use Battery, select Never. Under the Alert option, deselect Alert for deficient battery and Alert for serious battery shortage.
2.Disconnect the power adapter and use the battery until the computer is powered off due to exhaustion of the battery.
3.Connect the power adapter until the battery is charged to 100%. Before initial use of the computer (or resuming use of the computer after long-term storage), the battery must be charged to full.and discharged for 3-4 times to optimize the performance. The charging process takes more than five hours.
Note: When your battery is calibrated and reaches the best performance, set the Power Supply Options on your computer to the default value to ensure that the computer can send correct alerts to you, for example, low battery alert, and alert before the computer enters the hibernation status.
You must discharge the battery to let the computer power off, and then charge the battery to 100% to calibrate it. Then you can connect or disconnect the power supply anytime regardless of the status of the battery volume. Moreover, you can perform a deep charging and discharging cycle under control of the protection circuit in a time"

Tip

The Most Important Considerations of Using Laptop Battery


1, when no external power supply situation, if the working conditions at the time slot being less than PCMCIA cards, it is recommended to remove the card first to extend battery life.
2, room temperature (20-30 degrees) for optimum battery working temperature, the temperature is too high or too low, the operating environment will reduce battery time.
3, can provide stable power supply environment, using a laptop computer, remove the battery for extended battery life is not right by. On Asus notebooks, when fully charged battery, the battery charging circuit will automatically shut down, so the phenomenon of overcharging does not occur.
4, the recommended average of three months to conduct a battery power correction action.
5, to minimize the number of NIKON en-el3e battery
The battery charge and discharge is directly related to life, one charge, the battery a step forward to retirement. Suggest that you use an external power supply,
6, the use of an external power supply when the battery removed.
Some users often plug the power several times a day, and the laptop is equipped with batteries, do more damage to the battery. Because each access to the equivalent of an external power supply to charge the battery once the battery life shortened by a natural.
7, after the exhaustion of battery charge and avoid the long charging time
Regardless of your notebook to use nickel-metal hydride or lithium electricity, to power after the exhaustion of a certain charge (charge less than 1%), which is the best way to avoid the memory effect. Lithium also have memory effect, but its memory effect smaller than nickel-metal hydride Bale.
8, the usual precautions
When used in peacetime to prevent exposure to prevent damp to prevent the erosion of chemical liquids, avoid contact with the metal battery contacts, etc. happen.
When you purchase your laptop battery
Laptop battery life - as no more than 3 to 4 years, it may be users of the most likely to replace things. Two years after the laptop, you will find the battery consumption and faster. If possible, you can replace the old batteries for new batteries to ensure the stable operation of the computer.
When the need to replace the notebook computer batteries, best to choose the same type of battery replacement. However, if the old computer using a nickel-metal hydride batteries, to make a longer battery life, of course, can also be specified by the computer user manual or manufacturers recommended models use lithium batteries. Although the nickel-metal hydride batteries for cheap, but there is memory effect, and in the same capacity than the lithium batteries under the weight of large, and lithium batteries have no memory effect, light weight, power supply for a long time, etc., has become a standard notebook computer batteries . Lithium batteries used in notebook computers at this stage because the different manufacturers in the power of time there are some gaps, and friends in the purchase process should be noted that different brands of the difference in the Sony vgp-bsp13/s Battery, the best among several brands compare.
Performance battery power supply in addition to the stated time manufacturers, but also need to pay attention to their capacity. Battery capacity is usually AH (ampere-hour, ampere-hour) calculated with the current laptop is 4000AH most about, and a battery can last for 2 hours or more. In addition to the battery power supply time by the whole power of computers and the impact of factors such as heat dissipation, the screen size (bigger and more power), screen brightness, and the implementation of the work and so will affect the power of time.
Now the price of laptop battery up and down the ocean in 1000, accounting to 10% of overall price notebook - about some of the ultra-thin models or even higher. The battery warranty period, is guaranteed 3 months, and is guaranteed six months, the longest, but also for 1 year; the reason why the warranty time is short battery laptop battery is easy because of consumables, the number of charge is constant, with a little time. Moreover, the laptop battery and other hardware different, there is no room for repairs, can only be a new one. The products of such a long warranty (replacement), intangibles to increase the burden on manufacturers, so buy laptop, be sure ask the battery warranty period and conditions.
Also in the purchase of second-hand laptop computers, they also do not forget to try it inside the battery can continue to work long. Under normal circumstances, the use of one or two years after the laptop is fully charged, the nickel-metal hydride battery can support about 1 hour or so computers at work, lithium-ion battery can support nearly 3 hours, but relative to the terms of this new battery requirements are already very low, and able to meet this target from the scrap to the battery of far away.
Causes of Damage Laptop Battery
Notebook computer CANON nb-6l battery a long time, often charge less for electricity, and even shows the battery is damaged, the specific performance of a larger resistance, the voltage across the charging up faster. So easy to charge control circuit is judged to have been filled, the capacity will naturally decline. Since the battery internal resistance is relatively large, the discharge voltage drop when a large, fast, so the system is easy to mistakenly believe that the voltage is not enough, lack of electricity. Comparison of the discovery of short battery life, should take appropriate measures.

My c610 battery i have replaced it 2 times but it still dolesnt charges it stops it stops to charge during charging


Hi nabhanizatio

DELL LATITUDE C610 BATTERY CHARGE FAILURE

The likely cause of the original battery fault is a very common mistake in the way laptops are used. A laptop battery, working at optimum efficiency, whether of the older Nickel Cadmium and Nickel Metal Hydride or newer Lithium Ion types, is meant to charge under power and then discharge under use, if it is to have a long and useful life. This means that it should be used in a similar way to a cellphone's battery - connected to mains electricity and charged up when low or flat and then disconnected from the power and used on battery power alone until the power level means the cycle needs repeating. Many people, however, unwittingly use their laptops like desktop PCs and leave the mains electricity permanently connected to it even after the battery is fully charged. The reason that people cite for doing this is 'convenience'. This, however, is a mistake.

Laptops have more flexibility than cellphones in that, if they are mainly used in one place rather than as mobile devices, then it is possible to charge the battery to full capacity, disconnect from the mains, then remove and keep the battery until the next time the laptop's mobility function is required (periodically recharge the stored battery if not in use for long periods of time because the charge slowly dissipates when not in use), reconnect the mains to the battery-less laptop and use it like that, ad infinitum.

When a laptop battery is fully charged, what it really wants to do is discharge. However, maintaining the mains connection prevents it from doing so. The Power Management
System on the motherboard is designed to cope with long periods of either battery powered or battery-less mains powered use, but not long periods of simultaneous battery + mains powered use. A fully charged battery still connected to mains electricity has no means of discharging and various power sensitive components such as the Power Inverter, Cold Cathode Backlight, LCD Panel, Graphics Chip and Motherboard Power Management Stystem can become damaged by the power bottleneck created.

Using the battery in this wrong way also gradually depletes the charging capacity of the cells, until eventually, the cells can carry no charge, meaning a dead battery. A dead battery, where the cells are depleted, left in the laptop with the mains connected, is even worse for the Power Managent System
because the flow of power to the motherboard via the dead battery cells is inefficient and intermittent, creating battery overheating, low CPU Cooling Fan speed, inferior cooling and consequent internal overheating hazards in addition to potential electrical damage to several components. When damage to the Motherboard Power Management System passes a certain point, even a new battery might not charge - the situation in which you now find yourself.

Loose DC jacks, leading to intermittent power drops and surges, are typically caused by the jack being allowed to take the weight of the heavy transformer box on the laptop's power cable. The solution is to ensure that the laptop is never held, carried or used with the transformer hanging unsupported. If the laptop is in use, the transformer should be disconnected, carried, placed on a desk or table near the laptop (if the cord is short) or laid completely full-weight-flat on the floor (if the cord is long enough). Also, a Surge Suppressor/Surge Protector should always be used between the mains power socket and all computer
equipment, rather than directly to the mains.

If either the Motherboard Power Management System or DC Jack are ever damaged, your laptop would require professional specialist repair by a Component Level Laptop Repair Specialist, providing No Fix No Fee, Warrantied Repairs ( typically 3-6 months Repair Warranty).

I hope this helps.

Respected i have d610 the charging light blink 3 time red then green and not changing the battery


First of all, you need to make sure your power adapter is providing enough power to both run the laptop & charge the battery. A very good way to do this is to compare your laptop voltage & ampere requirements (written on a sticker on the bottom of the laptop) with the voltage & ampere ratings of the power adapter. Voltages should be the same, or the power adapter's voltage about up to 0.5 volts more than the laptop's voltage rating. Amperage of the power adapter should be at least equal to or greater than the laptop's rating. It should never be less than the laptop's rating, or else the power adapter will be providing insufficient amperes to charge the battery. Of course, the power adapter's nominal amperage might be ok, but it degraded on usage. You can verify this by testing using a good or new power adapter.
If the battery did not charge using the new power adapter, take the battery off the laptop, & using a dry tooth brush, scrub in between the fins of the battery connector on the motherboard & on the battery it self, then put the battery back into the laptop & try again.
If this still did not resolve the problem, then the battery itself could be bad. Try it on another laptop, or try a good or new battery in your laptop.
If this did not work, there might be a possibility that the charging circuitry on the laptop's motherboard is defective & needs servicing. In order to do this, the laptop needs to be disassembled & the motherboard checked for defective/burned out components in the area near the DC jack. Any defective/burned out components found should be replaced, or you might need to replace the laptop's motherboard altogether.

Hi my acer aspire one charg only 79 % not 100% plz solve my problam


Remove the Battery
Sometimes the battery may get dislodged from its chamber due to some movement. This will inadvertently mean that laptop battery will not charge since it is not placed in the right position. Removing the battery and then placing it back in its place properly will show you if this was the reason why the laptop battery was not charging when plugged in. There are a number of connectors that work in tandem when the battery is being charged, and the displacement of even one of these components leads to the laptop battery not charging problem.

Refresh the Battery
Some manufacturers of laptops provide the option of refreshing the battery after it has been used for a period of time, in order to enhance and prolong its life. Read the manual that you received with your laptop and check if this service is available to you. This can be carried out by entering the BIOS or the CMOS setup, and the instructions for this will also be provided in the manual for your laptop.

Replace the Battery
In all likelihood, the reason why yours Acer Aspire One is not charging is that the battery has worn out. Like all electronic components, the laptop battery is also culpable to deterioration over time, and due to this it may not be getting charged at all. In such a situation, you have no choice but to simply replace the battery with a new one. This will solve all your problems and also give your laptop a new lease of life. You may wish to know more about how batteries work.

Thanks for the info mate. Also to mention that some HP laptops have air vents at bottom, so they cant be placed on bed or even lap for a long time. This causes overheating, and again reduces the battery life.

Hi,
Its recommended that you use the laptop straight away to run the battery out, then you can charge it and it will hold 100% charge thereafter as batteries have an in built memory.

Hi there
Take the battery out and start the laptop up on AC power only, set the correct date, time and time zone, shut down the PC and remove the power jack, wait about 30 seconds then power it up on AC only again, If the date and time has changed the the cmos battery has run out and needs replacing. If it keeps date and time the problem is the battery or the powerboard controller that charges the battery is defective. If the battery is getting a charge, run the battery completely out of charge, then try to charge it again.

Good luck and thanks for using Fixya!!
