How to prolong the life of camera battery ?

Wednesday, March 4th, 2009
Digital cameras rely mainly on battery power, but if you are using does not match or pay no attention to save the battery, the battery will be shooting at you do not run out a few photos. Of course, the battery will eventually run out, when you discover that they are depleted, you need to replace them.

The preservation of battery, carrying also have a lot of attention should be paid to the place. Just bought rechargeable batteries generally very low or no consumption of electricity in charge should be conducted prior to use. After the battery is full of electric hot should be cooled and then into the camera. In order to extend the shooting time, shooting the process should be as far as possible not to use LCD viewfinder; to reduce the number of optical zoom; to reduce the use of flash number; should pay attention to the integrity of skin cell insulation if it is found that damage should be transparent cement plasters.

When in use as far as possible we want to save battery usage. First of all, avoid using unnecessary zoom ** for, if it is to zoom, we suggest you to move the camera position to get the same zoom effect! Second is to avoid frequent use of flash, flash is a big power, it is recommended not to everyone if forced to general use. Furthermore adjust images at the best use of the viewfinder, and not to use the LCD screen. LCD display astonishing energy consumption, so the best use of, because ordinary shooting through the viewfinder can be completed. Of course, in order to save power consumption should not be blocking it, such as close-up shots at the time LCD display is an indispensable component. Finally, remember not to use a digital camera at a time when its turn off.

For the battery clean, most people do not pay attention to. In order to avoid the problem of electricity loss happened, please keep the battery at both ends of the contact point and the internal battery lid clean. If necessary, use a soft, clean cloth gently wipe do. Can not use sexual or chemical cleaner such as detergent solubility, such as diluents, or solvents containing alcoholic content, clean your digital camera, batteries, or charger. In addition, the use of charge, please do use a soft cloth to clean the battery contact points at both ends, as far as possible, the battery contact points at both ends to keep clean so that you can ensure that battery power can be completely adequate. If the battery electrode where oxidation has occurred, the need to wipe out, if it is a serious case of oxidation or loss should be immediately replaced with new batteries.

With the correct method of charging a great impact on the battery, use the original charger and battery will help extend battery life. The charging time depends on the charger and battery used, and the use of factors such as voltage stability. If you are using the first battery (or used for months without batteries), it is necessary to keep in mind that rechargeable lithium batteries must be the number of hours more than 6 hours, Ni-MH battery must be more than 14 hours, otherwise the future would be more battery life short. Normally taken after a few charge / discharge process in order to achieve optimum efficiency. And there are remnants of battery power when not to repeat the charge as far as possible to ensure that the battery life. If you are a nickel-cadmium battery, only charge a one will stop charging, and then recharge it, so the battery will not be filled. This is what we referred to the “memory effect”, this effect would reduce the battery’s total capacity and the use of time. Over time, the storage charge will be less and less, the battery also will be used faster and faster.

In addition, if you intend not to use a digital camera a long time, we must want from your digital camera battery charger inside or out, and fully discharged, and then stored in dry, cool environment, but not to the battery with the general storage of metal objects together. A long time because the battery stored in a digital camera or charger, may cause leakage and damage to question and so on. In order to avoid short-circuit the battery problem, the battery when not in use should be covered to protect its preservation. Storage has been fully charged battery to take extra precautions, no matter what type of batteries are the same, must not to put purses, pocket, handbag or other items containing metal container.

Lithium-ion battery security features

Lithium-ion dell laptop battery has been very widely used in people’s daily lives, so it should definitely be the safety performance of lithium-ion batteries are the first assessment indicators. For lithium-ion battery safety performance assessment indicators, the international community provides for very strict standards, a qualified Li-ion batteries in the safety performance should meet the following conditions.

(1) Short Circuit: No fire, not explosion

(2) Overcharge: No fire, not explosion

(3) hot box test: no fire, not explosion (150 ℃ thermostat 10min)

(4) needle puncture: No explosion (Ф3mm nail penetration with batteries)

(5) the impact of flat-panel: no fire, not explosion (10kg weights since 1M height batteries)

(6) burning: No explosion (gas flame barbecue batteries)

Lithium-ion latitude d510 battery safety features are how to achieve the?

Lithium-ion batteries in order to ensure safe and reliable use, the experts had a very strict and careful design of the battery safety in order to achieve security assessment battery indicator.

(1) divide 135 ℃ Automatic shutdown protection

Adopting international advanced Celgard2300PE-PP-PE three-tier composite membrane. The battery temperature reached 120 ℃, the composite membrane on both sides of the PE film hole closed, the battery internal resistance increases, the battery internal temperature down, the battery temperature reached 135 ℃, when, PP film hole closed, the battery internal circuit, the battery is no longer warming, to ensure safe and reliable latitude d520 battery.

(2) add to the electric fluid additives

Overcharge the battery, the battery voltage higher than 4.2V under the conditions of electric and electro-hydraulic fluid additives in other polymeric material, the battery internal resistance of mates increased, the formation of large area internal battery circuit, the battery is no longer warming.

(3) the battery cover composite structure

The battery cover the use of explosion-proof structure notch, battery temperature, the battery internal activation generated by the process part of the gas expansion, the battery internal pressure increased, the pressure reaches a certain degree of notch rupture deflated.

(4) a variety of environmental abuse trial

For the misuse of tests, such as external short circuit, overcharge, acupuncture, flat shock, burning and so on, examining the safety performance of the battery. At the same time, the battery temperature shock test and vibration, drops, shocks and other mechanical properties test, inspect the battery in the actual use of environmental performance under the circumstances.

Lithium-ion latitude d600 battery are a new type of green environmental protection battery

“Care for the environment, the protection of the Earth” is our bounden duty of every individual. How the U.S. environmental philosophy reflected in the action then?

As a battery consumers should buy, the use of new green battery; as the battery manufacturers should be the production of new green battery. Only through the concerted efforts of everyone to create, protect our natural beauty and harmony.

New type of battery is the green environmental protection in recent years have been put into use or are being developed for a class of high-performance, non-polluting batteries. Has been substantial use of lithium-ion batteries, nickel metal hydride batteries and are promoting the use of mercury-free alkaline manganese dioxide batteries are being developed, as well as lithium or lithium ion plastic batteries, fuel cells, electrochemical energy storage supercapacitor are new green areas of the dell 312-0068. In addition, the current has been widely applied to the use of solar photovoltaic conversion of solar cells (also known as photovoltaic power generation), also fall into this category.
