The correct charging method for lithium batteries

In fact, the light put light rechargeable lithium more benefits, only in the power module lithium to do calibration, only deep deep release sufficient necessary. Therefore, the use of lithium-powered products do not have to rigidly adhere to the process, all to facilitate the first charge at any time, do not worry affect life expectancy.

Nikon D90 Digital Camera Parameter Description

Nikon SLR D90, in the end, not in appearance superior to others, have made great improvement in performance compared to the previous generation product. EXPEED image processing concept application for this mid-range SLR excellent high-sensitivity performance, real-time viewfinder, facial recognition features added to make the camp of the current mid-range SLR D90 leading in new technologies. About 92 million pixels 3.0-inch LCD screen provide the user with an excellent display in the SLR played back on a photo has also become a kind of enjoyment.

Optional camera battery tips

Buy a camera, pay attention to with the battery is consistent with the original machine. The battery into the machine, observe the power.
At the time of purchase, we should pay attention to the appearance of the battery damage, battery voltage is 12 volts and the battery capacity, date of manufacture, etc..

Digital Camera Battery Care and Maintenance

Digital camera on battery power, but if you are using a battery does not match or do not pay attention to saving, the battery will run out you do not have to take a few shots. Of course, the battery will eventually run out, when you find that they are depleted, you'll need to replace them.

Lithium battery safety performance test method

Lithium is the lightest non-gaseous in nature metallic substance, its intrinsic potential than any other metals are low compared with other types of batteries, lithium batteries, the ratio of capacity (capacity) of the unit weight and bulk density (unitvolume capacity) are the highest, have an unparalleled advantage.
In addition, the high internal resistance of the lithium battery, because of its internal electrolyte is a colloid aqueous solution instead. In addition, the very low moisture content, stable physical and chemical properties of the electrode material lithium battery can work safely in a wide temperature range. The individual lithium batteries can work in a low-temperature environment of -55 ℃ and 150 ℃ degrees Celsius temperature. Lithium battery rated output voltage of 2.7-3.6V

12-megapixel Canon SX280 HS Camera Parameter Description

Canon has released the PowerShot SX280 HS compact digital camera, Super Zoom, WiFi connectivity and GPS geo-tagging function. Despite the small size, this card has a cash specifications, is a good choice for users who do not want the expense of performance because of the portability. In its interior, a DIGIC image processor, and a 12.1 million pixel sensor, this combination helps to ensure high image quality and fast continuous shooting.

The cause of the lithium battery life shortened

In real life, lithium batteries commonly found in digital electronic products; often whether it is aware in the process of using the battery, the battery life is far less than the theoretical life.The reason is also controversial.Then the battery should be how to properly use it?Let us continue to find out.

Reasons: internal lithium battery lithium battery life is shortened factors:
1, the side reaction of the lithium-ion battery;
2, a lithium ion battery active substance irreversible consumption;
Large lithium-ion battery, battery current, heat slowly, easy to damage the battery structure;
4, if the additional security measures on the lithium battery, lithium battery provides power to maintain;

Distinction between lithium batteries and nickel-metal hydride battery

Rechargeable lithium batteries because of its small size compared to the ordinary Ni-Cd / Ni-MH battery (relative), light weight, low self-discharge, no memory effect has the advantage of a wide range of use in many new mobile devices. We usually use a mobile phone, laptop, PDA and other mobile devices lithium battery has been gradually replaced.

Teach you how to buy lithium battery

The lithium battery is divided into lithium-ion batteries and lithium polymer battery. Lithium-ion battery electrolyte flowing solid polymer lithium battery electrolyte, lithium-ion battery is more volatile than the lithium polymer battery, hit the external blows, or does not meet the standard charger, may cause the battery to explode. The batteries are lithium batteries use a lot of mobile phones, laptops, digital cameras and other portable electronic products. Buy poor quality lithium battery, just like in his side put a "time bomb". Therefore, consumers in the purchase of lithium battery must pay attention to the following points:

Canon 60D Digital Camera Parameter Description

Canon 60D is an upgraded version of the mid-range SLR 50D, its appearance is more inclined to 7D, 60D LCD is a relatively new, 3-inch 1.04 million pixel can flip the screen, this is still the first time in a Canon SLR, compose the shot is more convenient ; the other hand, the proportion of 3:2 ratio LCD, and SLR camera shot pictures coincide more full display pictures. Functions 60D new 1920 × 1080p Full HD video capabilities. The battery used 7D same LP-E6 endurance than the 50D upgrade a large portion. It is noteworthy that the 60D began using SDHC cards, and did not follow the 50D CF card, which is commendable. In short. In addition to upgrading a few technical compared to the 50D, 60D and no special advantages.
