How to maintain a digital camera battery

DC used today generally have two kinds of laptop battery: lithium battery, and dedicated on the 5th AA batteries (Ni-MH rechargeable battery most commonly used). Lithium-specific light weight, large capacity, environmental protection, and virtually no “memory effect”, but very expensive, poor general, but also a lot of fakes. Ni-MH battery has a high capacity, deep discharge, overcharge and excessive resistance discharge, and shorter charge time obvious advantages. The most important thing is nickel-hydrogen batteries are cheap, high universality.

No matter what kind of Hp laptop battery, with DC as long as it is sold, the general statement in the Notes will be used, and some manufacturers even print a separate report on the use of batteries and chargers guidelines. Some of these instructions is the most basic but also very necessary road maintenance, such as battery charging method should be chosen, such as charge time. Unfortunately, many users tend to ignore these instructions, shelved. Suggestions: For DC novice, spend some time reading these guidelines, is absolutely necessary.

Ordinary users in the use of DC, the battery often do not have a dedicated storage bag; users to replace the Hp PB992A battery after the battery of the habit easily placed, regardless of whether the place where a clean, damp. The consequences of such a battery is easy to stain, easy contact with the metal contacts  such as keys, etc., easy to damp, and these are the enemy of batteries. Recommendations: the user should set up a special place at the battery and keep the battery clean. In order to avoid issues such as power loss occurred at the two ends of maintaining contact with the battery and internal battery lid clean and, if necessary, use a soft, clean dry cloth graze.

If DC does not use a long time, the Hp 398876-001 battery must be removed from the machine and kept in dry, cool environment. This is no disagreement that we are all, but why here also brought up for discussion? Because it relates to another key issue: For the nickel-metal hydride batteries, the battery should be fully discharged and then save, save, or live? These two very different views of what it should be used? Many people think that we should adopt the former, but I think a more reasonable to preserve the battery charged. Because: According to tests, Ni-MH battery to preserve the best condition that saved about 80% charged. This is because the nickel-metal hydride Hp 337607-003 battery greater self-discharge (10% -15% a month or so), if the battery fully discharge and then preserved a long time not to use, the battery will result in the phenomenon of self-discharge the battery over-discharge, will damage the battery. Do not believe? What do you think about buying a new nickel-metal hydride rechargeable batteries is not all there is electricity, which is the reason. Recommendations: more than compared to correct the wrong point of view, from the right direction to start maintenance Hp 337607-001 battery, or else they will backfire.

Japan’s flexible solar cells a substantial increase in power

Researchers in Japan through technical improvements, the success of the flexible type of dye-sensitized solar cells a substantial increase in power, each 12 square centimeters can be the output of the battery plate voltage above 4 V, is expected to be used to provide power, such as outdoor advertising.

According to “Nikkei Sangyo Shimbun” reported that dye-sensitized solar cell-based film material in the pigment and power generation components used for power generation, and compared to silicon solar cells, and its advantages can be bent, using the printing technology, which costs relatively low . However, before such a flexible Hp Pavilion ZT3000 battery, even in strong sunlight, each 12 square centimeters of voltage they can only produce 0.7 volts.

Improved type dye-sensitized photoelectric conversion efficiency of solar cells up to 4 ~ 5%, is a standard silicon solar cells of 1 / 3. Maximum power of 0.4 watts, test products will be linked to the three modules, voltage up to 12 volts or more. Typically, the voltage above 10 V can be used for storage of electrical appliances and rechargeable lithium batteries, the average cell phone charge 4 hours to complete.

Flexible solar cells that, if the practical application of inputs for outdoor advertising, laptop computers-Hp EX942AA battery, cell phones and home appliances, such as the provision of power supply products.
