Speaking of Compaq laptop battery, most of users will associate it HP. Indeed, it has become a member of HP for nearly 9 years. However, for always keeping a low profile, many users don’t know clearly about its glorious past.


Compaq was established in 1982 by three senior managers from Texas Instruments Inc. In early times, Compaq had helped IBM to have its first section of PC portable computer which was said to be an ancestor of laptop. From then on, many laptop accessories of IBM were provided by Compaq.


Indeed, the quality and performance of Compaq laptop battery is of world-class level. It is believable that nearly no one can be compared to it. Although it has a history of only twenty-odd years, its achievement is very notable, which is really a miracle in laptop industry. However, it didn’t leave me a deep depression for its low profile.


As for Compaq Evo laptop battery, it is an accessory of Compaq high-end business series. At that time, for many businessmen, they prefer it to IBM T series, which is not only for its high performance but for its humanity design as well. Whatever, users can only feel the benefits after using.


In 2002, Compaq laptop battery was officially become a new HP laptop battery. Many people might think it is about the failure of Compaq in acquisition of DEC. In fact, it was the excellent service that made HP to surpass IBM in only a few years. Before consolidation, HP was always poor in its maintenance, after-sale service and consulting.


Although Compaq is not so good in business strategy, we just can’t help to consider it a silent contributor in the market. Without it, maybe we won’t have such a good performance laptop computer and accessories.

For the laptop battery, if it is installed in the laptop, when connected to the charger, it must be charging. As there must be a little exhaustion in a period of storage, it is impossible to reach 100%. Even if the charging time is short, each time it is connected to the charger, the battery life reduces. Certainly, the conditions vary from all laptops. Before operation, it is better to check the laptop instruction.


How to charge the laptop battery properly?


laptop battery charging

For one thing, it is best to discharge the laptop battery until shutting down automatically each time.


For another, it is unnecessary to be particular about it. You can charge it whenever you want.


Indeed, neither of your two points is correct. Normally, when the remaining power comes to be 3%, it will remind you to recharge. Certainly it can be set by yourself.


Suggestion:


No matter it is a li-ion battery or a Ni-mh battery, the memory effect exists. Comparatively, the effect is much more obviously in the Ni-mh batteries than that in the li-ion batteries. The incipient dell laptop battery is a Ni-mh one.


Some statements that there’s no memory effect are only the means of propaganda. It is best to charge the battery when it occurs to be 3% of power remained. As to the latter point, the operation will reduce the battery life rapidly.


Therefore, it is no need to recharge the battery until shutting down automatically. Due to the circuit to prevent it from overcharge and overdischarge, even if the laptop is shutting down automatically, the remaining power hasn’t reached the dominant value. Certainly, for the memory effect, it is good for the battery to be exhausted before charging.


As to the li-ion batteries, such as compaq evo laptop battery, the influence of the memory effect is far inferior to that of the natural loss.
