Battery Performance - what you should notice when choosing a laptop battery

When you are choosing a laptop battery in a shop, you should not buy one appropriate to take away, Battery testing is an essential part. One of the most important test is view the number of charge cycles, the second is the standby time. Many people think that the laptop battery life calculated in accordance with the useful life, in fact, really play a decisive role factors should be fully charge and discharge times. In general, international brands of notebook products will have a battery management tool in its accompanying software, This tool through read the intelligent control chip inside the battery pack  to see such as the use of time, the battery design capacity, the actual capacity, as well as the charge and discharge times and other information. Through it users can understand some information that can not be seen on the laptop battery surface label.

If you buy a brand new original laptop battery, you should pay attention if the battery’s charging times is 0 or not, (the number of charge cycles up to 2 or 3 times, because some merchants will also conduct charge and discharge test after purchasing the batteries). The second is to check the battery capacity, compare the full charged capacity with the battery’s design capacity, if you found the full charged capacity less much than the design capacity, it means the battery’s performance has been a significant reduction, it suggested not to purchase. If your notebook’s battery management program does not have the option to see if the laptop batteryis fully charged or not, you can take advantage of BatteryMon and other software to detect. (hp pavilion dv4 battery)

If conditions permit, it is best to try to use with the full charged battery that you want to buy in the laptop, conduct surf the Internet, DVD playback and other operations. When testing, if you find the screen suddenly bright flickered or irregular flashing, or the discharge curve of the battery monitoring software is not smooth and the power sags phenomenon (For example, suddenly dropped from 70% to 6%), it means the battery-powered is not stable enough, may be the quality of the internal cells are not good enough, or the circuit design is not in place, these batteries should not buy. If the time is plently, you can always test until the battery is exhausted, finally account the actual use time of the battery in the normal range. But you should pay attention, it is very hard to achieve the standby power consumption required by the official during the actual test, so when the gap of the battery’s use time is not too large with the official nominal, it does not prove that the battery has problem. (hp pavilion dv4 battery)
