Hewlett-Packard was founded in the difficult times of the Great Depression. The founders were a pair of friends whose name the company still proudly bears. They started their business in an unobtrusive garage near the city of Palo Alto. It is now a national monument. HP’s success lay not in copying existing products, but in the ability and courage to come up with something new.

The first commercial triumph was an oscillator that surpassed all competition in quality, yet sold at a quarter of the price. In 1968, HP released their first desktop computer - a desktop calculator. The company currently manufactures products primarily related to computer technology - computers and laptops, printers, scanners, digital cameras, servers, and last but not least, calculators.

Enhanced 100 Watt-hour battery for most older Sandy and Ivy Bridge-based laptops HP. Inside is 9 Sanyo ICR cell. Somewhat disappointing when acknowledge that Panasonic NCR18650A are available for almost 5 years and are considerably safer than the old ICR manufacturing technology. Moreover, they have nearly doubled the guaranteed cycles. In addition to my 8470p (but I confirmed it on other) is not discharged simultaneously with the primary battery, but completely takes over the load. Although not the fault of "the product" but that assessment can not be omitted. For knowledgeable Lithium Ion technology is not necessary to recall that the article to be 0% (2.5V) or 100% (4.2V) is not ideal and shows it on its lifetime. After connecting to the laptop starts to discharge only extended battery and only when it is at 0% then discharges the primary. For this "switch" In addition, there is no any indication. On the road where there is no possibility of extended battery pack charge is therefore doomed to remain at 0% thereby rapidly reducing its overall lifespan. When charging, the situation is reversed - will be charged with first primary and then the widespread, so it is at 0% even longer and while the primary 100% charged status is again, which is good in the long run to avoid. It is therefore up to the user monitors the state of charge cells and at the right time extended manually disconnect battery, and in the case of primary charging disconnect before reaching 100%. Moreover, it complicates the fact that overlaps the extended lock on the primary battery. The situation would be avoided while taking the distribution into two battery packs, eg. 10% would be achieved at the same time as well as both simultaneously charge current half again so, whether e.g. 90% is reached at the same time. This would also prolong the life of cells, they would be burdened with significantly smaller charging and discharging currents.
Other 100Wh is always useful charge indicator is very useful HP connector for charging laptop outside The selling price is not cover production costs surcharge will not be discharged simultaneously with the primary battery, which brings a wide range of problems (see text) HP connector is not connected to the battery "sens" pin - you can not control the speed of charging.
