Do you know the difference between primary and second battery?

The primary battery can just only discharge one time, but the second battery can be rechargeable again and again. When discharging a rechargeable battery, both of its electrode volume and structure cause a reversible change. So the design of the rechargeable battery must be adequate to adjust these chemically changes.

As it is known to us the primary battery’s internal structure is simpler, it doesn’t need to accommodate reversible volume changes. These primary battery have larger quality ratio and volume ratio than the rechargeable batteries, however it has much bigger impedance, therefore the load capability is low.

Furthermore self-discharge of a primary battery is far lower than secondary one.

As far as it is known to every laptop fans, the original laptop battery is much dearer than the OEM. Sometimes you might be cheated and buy an OEM laptop battery at the original price.

The OEM laptop batteries are mainly composed of three parts: battery cells, PCB and the crust.

whether the laptop battery life is perdurable or not mainly depend on the battery cells, In this case, once ordering original notebook batteries, you must verify the information that whether the cells is in good quality or not, as far as we know, the battery cells plays an important part in laptop battery life.  And of course the good quality battery cell quality is much better and have good talented,

On the other hand, the hardware works to prevent the explosion.  Once an exploding happens, everyone around the laptop will be extremely dangerous. if the battery cells is defective , it is better not to use. After all safety will be the most important factor.

The last one factor will be insulation material, which is absolutely very important. For any situation that the insulation material fails to work normally, the circuit might be shorted, drawing a lot of current. In this situation once the material is too defective, the protection circuit can not run as well. A fire accident might be caused by this, and even the exploding happened once the battery is heated. It is very very dangerous

Another important thing will be the manufactured procedure, the laptop battery supplier should make it work with the original laptop, determining that whether there is compatible problem and other faulty issue.

Of course, it will be undoubted that it will be safe when the laptop battery has passed the CE, UL, Rohs and other certifications.

Have you ever been confused of short laptop battery life?
Have your new laptop battery could not reached to its standard capacity even when fully charged?
Have your ever thought of an idea of enlarging your laptop battery?
Do you know what you should do when the new laptop battery is in your hand?
Do you know the tips of how to Maintening your battery?

The following tips could help you:

Usage Tips：
If you find yourself with no electrical adapter or power source and need your laptop battery to operate for as long as possible, here are a few tips you can try when your notebook computer is in battery mode:
1. Use the notebook’s power management system
In Microsoft Windows the “Power Options” power management application can be found inside the Control Panel. In the Power Options Properties tab select the “Portable/Laptop” power scheme. Many notebook manufactories also provide their own custom power management applications, which help to optimize power usage and extend battery time.
2. Turn down the display brightness
You can lower the LCD brightness level to use less energy. In fact a lower brightness level also strains the eyes less and causes less fatigue.
3. Close any unused applications
Applications are a burden on the system and require energy to run. Closing any unused applications will reduce that burden and any energy consumption down the line.
4. Remove any unused PC Cards or USB devices from your notebook
These devices require energy even when they sit idle, so removing them can help to extend your notebook’s battery time.
5. Disable Wireless LAN or Bluetooth network adapter when not in use
Ditto for the Wireless LAN or Bluetooth network adapters.
6. Increase system memory
Your computer stores data for use by the CPU in system memory or as virtual memory in the hard drive. Increasing system memory helps to reduce the system’s reliance on the hard drive, which uses more energy than system memory.
7. Reduce unnecessary optical drive operation/activity
Avoid activities that require your optical drive to operate constantly, such as listening to CDs.
8. Avoid graphics intensive applications
The notebook system will run in a high performance settings when using these applications, causing the battery to run down at a very quick rate.

Let us also take a look at the Maintenance Tips：
Almost all notebooks today utilize rechargeable Lithium-ion (Li-Ion) batteries. Lithium Ion provides many benefits over earlier Nickel-Metal Hydride (NiMH) or Nickel Cadmium (NiCd) Batteries, including less mass, better performance, and insusceptibility to the so-called “memory effect”. Despite these benefits you can maximize your battery’s lifespan by following these maintenance tips:
1. New batteries must be fully charged before use
To put your battery in optimum condition for long-term usage, please fully charge the battery before its first use. Very importantly as well, for the first 3 charge cycles, always fully charge before use and fully discharge before recharging.
2. Calibrate the battery every few months
Almost all laptop batteries are created with an internal microprocessor, which provides an estimate of battery conditions such as number of charges, discharges, full charge capacity and cycle charge count. The full charge capacity will become a little inaccurate after a few months and calibrating it can help restore the battery’s performance.
Some notebooks provide calibration tools in the BIOS or a Windows application. If your notebook provides either of them, you can follow these three steps prior to calibration:
1. Plug in your notebook’s power adapter and fully charge your battery.
2. When your battery is fully charged, disconnect the power adapter and use your notebook in battery mode. Disable all battery warning operations in Power Options Properties such as Shut down, Stand-by or Hibernation. When the remaining power is 3%, close all running application and allow the notebook to shut itself down.
3. Plug your power adapter in and fully charge your battery. Your battery has been sufficiently drained for calibration.
3. Use your battery in the proper conditions
Generally speaking, batteries work best at around 68°F (20°C), but temperatures between 32° to 95°F (0° to 35°C) will allow a battery to works in good condition too. Allowing your battery to work in conditions that are too hot or cold can lower its performance. It may also have a negative influence on the battery’s lifespan as well.
4. Store your battery in the proper conditions when not in use
If you don’t plan to use your notebook for a month or more, we recommend the battery be stored separately in a clean, dry and cool place. Please also ensure that the battery has about a 70% charge remaining. During storage the battery will perform a slow self-discharge, so we do not recommend storing it for a very long time (3 months or more), because it can impact the wellbeing of the battery.
Other Information：
Higher capacity battery or spare batteries
Some notebooks may be offered with an option on a higher capacity battery, which may also be offered as a separate purchase. You can take advantage of both to extend your notebook’s unplugged time.
Replace the battery
A battery that has been cared for properly should provide at least 300 full charge and discharge cycles. You can choose to purchase a replacement battery when your original battery longer is no longer able to serve you properly. The main symptom of this is a much shorter runtime even after calibration.
Battery recycling
Please do not dispose of old laptop battery in the rubbish bin as they can pollute the environment. Batteries should be recycled or collected for safe disposal through your local municipal or commercial programs.
