1. To use software tools to detect
Generally speaking, international brands of notebook battery products will be provided a battery-management tool in the CD-ROM, such as the ThinkPad’s Thinkpad Configuration, SONY’s PowerPanel. This is a tool we can use this software to read the intelligent control chip of battery,then,we can learn about the design capacity of the battery, the actual capacity, and the other information
However, these tools only used to the original battery, I recommend using this software – BatteryMon, the parameters of the battery can be visualized to them. BatteryMon can read the information of the PCM board of battery, and due to the core for batteries, keeping the original circuit, it is still an original batteries BatteryMon “eyes”. In this regard, we can choose a battery from the capacity information, in general, the capacity of core for the actual battery is often not consistent with the design capacity.
2.Look at the appearance
When We buy notebook battery should to check carefully whether the battery’s shell is a good process, the edge of the battery is fine, the print is clearly or not. There was a clear distinction between genuine and the fake in details. If convenient, use BatteryMon to detect the battery manufacturer and part number. Here we proposed to bring your original battery when buy the replacement battery, and compare with the original carefully.
3.selected a battery through the smell
If you are sensitive to odor, you can try to smell. There are kind of factory-specific flavor in the new original batteries and the compatible batteries (similar to sandalwood, I believe more accurate that this is a plastic smell), and the specific odor is not a common perfume scent that can be replicated. But if the battery is renovated, because used many times, the counterfeit batteries have no smell, used the adhesive to agglutinate the battery cells together, there will be irritating odor
4.selection from weight
The weight of notebook batteries is directly proportional to the quality , you can compare the weight to the original battery. It is necessary to pay your attention if it’s lighter than the original battery. Of course, sometimes this approach is not very accurate, for example: the old battery of nickel-metal hydride battery cells.
5.According to the warranty period to authentication
If the warranty period is not more than six months,we should be careful, because of consumables belonging to the battery, recharging is a constant, with many times, general speaking, the counterfeit batteries will drop the endurance performance after a month or two, will can not be recharged. It can be said that according to the warranty period to judge whether the battery is a new or not, at least to judge whether the battery cells is new or not.

When one thinks of value-for-money laptops, a trio of major brands spring to mind and Acer is invariably in the top three. Though the Taiwanese maker does not offer the flexibility to configure the hardware at point of sale that Dell machines do, Acer portables come in many different flavors, from Pentium Dual-Core chips to the latest AMD Puma platform.
