digital camera battery

A digital camera battery is probably the most important digital camera accessory. Some digital cameras can consume power at an incredible rate, providing only a few hours of continuous shooting time before the battery is exhausted. Other cameras are famous for the long life of their digital camera battery which allows users to snap away with barely a thought to power consumption. It is important to know how you plan to use your camera and what kind of battery it needs.

There are two types of Digital Camera Battery. Hp laptop battery The most widely available digital camera battery is a standard AA-size battery. The other type is a rechargeable battery that is made by the manufacturer, otherwise known as a proprietary battery.

A proprietary digital camera battery offers the advantage of being lighter and more compact,HP 342661-001 Battery,, HP pavilion dv6000 Battery(hp dv6000 battery)
HP Pavilion dv8000 Battery(hp dv8000 battery), but they are often more expensive, making the prospect of buying one or two backup sets much less appealing.

The alkaline AA-size digital camera battery usually has a very short life - less than an hour in extreme cases - when used in a digital camera. This type of battery makes an acceptable emergency backup, especially if you are travelling with your camera. However, the Nickel Metal Hydride (NiMH) digital camera battery can be used instead of the alkaline ones with a Charger and this rechargeable digital camera battery has a substantially longer life at an affordable price.

Another type of AA-size battery is the non-rechargeable Lithium A1045 batteries and rechargeable Nickel Cadmium (NiCD) batteries. The lithium digital camera battery has a superior life to alkaline AA’s and offers good cold-weather performance but their price and non-rechargeable feature make them less useful than rechargeable NiMH batteries. It is also important to ensure that your camera can take a lithium digital camera battery. On the other hand, the NiCD digital camera battery offers the advantage of retaining their charge while unused, unlike NiMH cells, but have shorter lives and need to be discharged completely before recharging which could be very inconvenient.

The LCD screen of a digital camera is responsible for consuming the most power, HP 342661-001 Battery so it is worth only using the LCD when necessary to help save the battery life. Always try to carry at least one backup set of batteries, especially if you plan on being away from power outlets for an extended period of time. The current alkaline AA-size battery can make a convenient emergency backup if your original digital camera battery fails.

Researchers at the Uppsala University in Sweden have developed a new thin-film battery made from salt and cellulose. This salt and paper battery uses a thin-film which makes it an attractive feature for many portable devices that draw a low current. It can be used in many low-power devices, such as wireless sensors, smart cards, medical implants and RFID tags.

The cellulose is derived from a polluting alga found in lakes and seas. The alga’s walls contain cellulose that has a different nanostructure, which gives it 100 times the surface area. The lightweight, rechargeable battery is made by coating the paper, HP 342661-001 Battery,, HP pavilion dv6000 Battery(hp dv6000 battery)
HP Pavilion dv8000 Battery(hp dv8000 battery), made from this cellulose, with a conducting polymer, and inserting a salt-solution-soaked filter paper between the paper electrodes.

In comparison with a lithium battery that would take 20 minutes to recharge, this new battery can be recharged in tens of seconds because the ions flow through the thin electrode quickly. The salt and paper battery will be made available to distributors in about three years. For the moment it is still in the early stages of development.

The differences between Ni-MH battery and Lithium battery

1, the weight

Each one-voltage battery cells of view are the nickel-metal hydride and nickel-cadmium 1.2V,HP pavilion dv6000 Battery while the lithium battery is in fact only 3.6 V, voltage of the lithium battery is 3 times the other two. And the weight of the same type of lithium battery and nickel-cadmium batteries is almost equal, while heavier than Ni-Ni-MH battery. We can see that the battery itself, the weight of each different, but the top of the lithium battery voltage of 3.6V, as in the case of the output voltage is equal to the number of combinations of a single cell may be reduced after the third is forming the battery weight and size reduction.

2, the memory effect



Nickel-metal hydride batteries and nickel-cadmium batteries have the same memory effect. Therefore, the direction of the regular discharge is necessary. This regular discharge management are at the fuzzy edge was treated, or even some knowledge of improper conduct discharge (discharge or use a number of times each time after discharge were the result of the company vary) This landfill management cumbersome use nickel-hydride VGP-BPS2B batteries, metal can not be avoided. In terms of lithium battery, because of no memory effect, it’s very practical and easy to use. It is completely without regard to the residual voltage is how much can be charged directly, charging time can be shortened by nature.

3, self-discharge rate

Nickel-cadmium batteries discharge 15 ~ 30% (month). Ni-MH battery for 25 ~ 35% (month), a rechargeable Lithium is 2 ~ 5% (month). HP Pavilion dv8000 Battery Than nickel-metal hydride batteries self-discharge rate is highest, while the lithium satelite battery expertise with the other two types of rates of discharge of the battery compared to very low.

4 Price

Nickel-metal hydride batteries and lithium batteries can not be insensible to overload. Therefore, nickel-hydride batteries, metal mode constant current load control PICK CUT when the charging voltage is higher, HP 342661-001 Battery,, HP pavilion dv6000 Battery(hp dv6000 battery)
HP Pavilion dv8000 Battery(hp dv8000 battery), to stop the load as the best means of support. The lithium batteries using a constant current, constant voltage mode, the best, if nickel cadmium battery charger DV-controlled manner, while pairs of nickel-metal hydride batteries and rechargeable lithium batteri
