Now, a digital camera is mainly rely on battery with power. Use the battery also has a lot of attention to the place, so that they can make a battery "prolong life".
In order to avoid the loss of the power problem, you want to keep the battery on both ends of the contact points and the battery cover internal clean. If the surface is very dirty words to use soft, clean dry cloth FuShi gently, can never use clean sex or the chemical has the solubility cleaner, such as diluent or contain alcohol solvent composition of the clean your digital camera, battery or charger.
For charging time, depends on the charger and battery, and whether the use of voltage stability, and other factors. Usually the first time to use the battery (or several months used battery) charging, li-ion batteries must more than six hours, the nimh batteries must be more than 14 hours, or future battery life will be short. And the battery and residual power, try not to repeat charging, to ensure the battery life.
Use process to avoid a discharge. A discharge is a power consumption over limit. Otherwise even recharge and its capacity cannot fully recover, for the battery is a kind of damage. Due to a discharge can lead to bad battery charging efficiency, reduce capacity, therefore camcorders are equipped with battery alarm function. So in similar circumstances should appear to replace the battery, try not to let the batteries run out and make the camcorders automatic shutdown.
The preservation of the battery
If you plan to use a long time without digital camera, must want the battery from a digital camera or remove the charger, and the discharge completely, and then stored in a dry, cool and environment, and try to avoid the battery and general metal items stored in together. In order to avoid short-circuited batteries, in batteries need not when, should cover to protect its preservation.
The green environmental protection battery is to point to in recent years has been put into use or are development, the development of kind of high performance, no pollution batteries. At present already use large nickel metal hydride battery, the lithium ion battery and is expanded use of mercury free alkaline battery manganese zinc and rechargeable batteries and is research and development of lithium or lithium ion plastic pack and fuel cells belong to this category. In addition, it is widely used and use of solar energy for photoelectric convert solar cell (also called photovoltaic power generation), can also be included in this category.
Nickel metal hydride battery (Ni-MH) and nickel cadmium battery (Ni-Cd) have the same working voltage (1.2 V), due to the adoption of rare earth alloy or TiNi alloy anode materials for the activity of hydrogen storage material, replacing the carcinogen cadmium, which not only makes this battery became a kind of green environmental protection battery, and make a battery of energy than increased nearly 40%, to 80-60 Wh/kg and 210-240 Wh/L. The battery is 90 s gradually realize industrialization PANASONIC VW-VBK360 Battery , and the first to use in the cell phone battery. At present although it on their dominance of the gradually be lithium ion battery replaced, but mobile phone applications in Europe and America, and its market share is still at about 50%.
The lithium ion battery (Li-ion) is by can make the lithium ion embedding and take off the carbon embedded as negative, reversible intercalated-li metal oxide as the positive (LiCoO2, LiNiO2 or LiMn2O4) and organic electrolyte constitute, the working voltage of 3.6 V, so a lithium-ion battery is equivalent to three cadmium nickel metal hydride battery or nickel. Thus the batteries than energy is the over 100 Wh/kg and 280 Wh/L, and considerably more than the nickel metal hydride battery than energy. In view of the above advantages, since the 1993-2000 in just a few years, its production and usage with extremely high speed growth.
Alkaline manganese zinc dry (alkaline) compared with ordinary dry cell size has higher capacity PANASONIC CGA-S005E Battery, and have high discharge current ability. In recent years has been used on mercury zinc powder, therefore make the battery become a green battery, and become the mainstream battery products, at present the alkaline xinmeng dry cell is still BP machine use most power supply. At the same time, the world is the battery charged on the sex, an American company has launched a charged battery alkali manganese, product and application of slow growth. Such batteries keep the battery discharge characteristics, but also can be recharged using a dozen times to hundreds of times (deep recharge cycles life of about 25 times).
Lithium plastic battery (LIP) is for lithium metal anode, conductive polymers of electrolyte for new battery, the energy than has reached 170 Wh/kg and 350 Wh/L. The lithium ion battery is will present plastic of organic lithium ion battery electrolyte stored in a polymer membrane, or use conductive polymer as electrolyte, make a battery in no free the electrolyte. Such batteries can use aluminum plastic composite membrane realize hot pressing encapsulation, with light weight, shape can be arbitrary change, safety better characteristics.
Fuel cells (FC) is a kind of use of fuel (such as hydrogen or contain fuel) and antioxidant (such as pure oxygen or the oxygen in air) for power generation device directly, because avoided the carnot cycle limit, this power unit is not only high efficiency (electrochemical reactions conversion efficiency can be as high as 40% or more), and no pollution discharge gas, so is the future of efficient and clean power generation method. Many companies at home and abroad are engaged in development for mobile phones, notebook computers, the PEM fuel cell, once put into application, and its economy benefit greatly.
Seal lead-acid battery is a kind of lead-acid batteries.
The following new green battery technology and related industry development is rapid.
1. Hydrogen storage material and nickel metal hydride Battery-the nimh batteries (PANASONIC CGA-S101E/1B Battery)
2. Lithium ion embedded material and liquid electrolyte of lithium ion battery
3. Polymer electrolyte of lithium battery or lithium ion battery
4. Zinc air battery and PEM fuel cell
In addition to the above, in view of the communication industry growth, China's battery industry is with extremely high speed to promote environmental protection mercury-free alkali manganese zinc original pool and rechargeable batteries and seal lead-acid battery technology development and application expansion market.
If users want to prolong battery the efficient use of the time, in addition to the quality of the charger to have the guarantee, the right skills and charging is essential, because of low quality charger or wrong charging methods would affect battery time and life cycle, the following is about to charge skills:
1. The battery before they leave the factory, manufacturers were activated processing, and the charge, so the battery are more electricity, my friends say battery charging adjustment period in accordance with the time, standby still seriously insufficient, assuming that the battery is really quality goods battery of words, this kind of circumstance should extend the setting and then 3 ~ 5 times fully charge and discharge.
2. If new phone is lithium ion battery, so before 3 ~ 5 times charging commonly known as adjustment period, should be charged more than 14 hours, in order to ensure that the fully activate lithium ion activity. The lithium ion battery no memory effects, but have very strong sui sex, should give full activated PANASONIC CGR-D220 Battery, to guarantee the use of after can reach the right performance.
3. Some automation intelligent quick charger when instructions lights change, said only full of 90%. The charger will automatically change with slow charge will batteries. Best will use after batteries, otherwise, it will shorten use time.
4. Before charging and discharging lithium battery does not need special, but will not discharge damage to the battery. As far as possible when charging at the slow ChongChongDian, reduce the way quick charge; Time don't more than 24 hours. The battery after three to five times fully recharge cycles of internal after chemical will be all "activate" to achieve the best use effect.
5. Please use the original or the reputation of the good brand charger, li-ion battery to lithium battery charger with special, and follow the instructions, otherwise, it will damage to the battery, and even dangerous.
6. Have many users often in charge still leave her cell phone, actually such will be very easy to PANASONIC CGA-S101E/1B Battery damage the service life of the mobile phone, because in charge of the process, the circuit boards of mobile phone can calorific, if this time more exotic phone, may produce instant backflow current, internal parts to mobile phone damage.
7. The battery life depends on the number repeatedly charging and discharging, so should try to avoid more battery electric charge when, this will shorten battery life. Cell phone time more than 7 days, supposed to completely discharge the cell phone battery, enough electricity before use.
8. The cell phone battery have self-discharge, need not when the nimh batteries will press the residual capacity every day, about 1% of the discharge, lithium battery every day to 0.2% ~ 0.3% discharge. In for the battery, try to use the special socket, don't will the home appliance such as the Shared and the TV charger socket.
9. Though the phones in the network coverage area, but in the cell phone charge, cell phones have been unable to accept and call. At this time, can use of the mobile phone is not transfer function, will be transferred to the mobile phone side of fixed telephone in order to prevent calls lost, this kind of method for mobile phone is not in the network coverage of the area or weak signal and temporarily unable to the applicable also.
10. Don't will be exposed to high temperature or cold PANASONIC DMW-BCG10E Battery , as the dog, should not put the phone on the car, and the sun blazed through the; Or get air conditioning room, in air conditioning to be blown continuously place. When charging, the battery is a little heat is normal, but can't let it what the high temperature "suffer". In order to avoid the happening of this kind of circumstance, had better be in charge at room temperature, and don't cover anything on the mobile phone.
11. Nickel cadmium (N iCd) before the battery must ensure that the batteries are no electricity, recharging the battery must ensure that sufficient electricity after.
12. If the cell phone battery placed too long and not use, the best maintenance department to cell phones to the application for a live processing, also can use a constant dc voltage is the voltage adjustment for 5 ~ 6 V, current 500 ~ 600 mA reverse connect battery. Note that a touch namely release, the most repeated three times can, through such treatment after another, with the original adapter to "adaptation" charge.
13. Charge is not as long as possible, to no protection circuit batteries that should stop after charging, or the battery will with fever or overheating impact performance.
14. Lithium ion battery must choose special charger, otherwise may not reach the saturated state, affect their performance. Charging completes, should avoid to place in charger on more than 12 hours or more, long-term need not when should make a battery and cell phone separation.
First the capacity of the battery life and said.
Battery capacity everybody can understand, is the capacity of the battery label printing! The greater the capacity to store electricity standby time more long more, but the battery life is put in charge of the circulation to describe, that is a charging a discharge for a cycle, now of the lithium ion battery general circulation 400 times the capacity of the nominal capacity is 50%-60%, professional predicate called attenuation rate, the capacity of the battery only nominal halfway through standby time and just bought at least by half, also is usually we the standby time behind mobile phone to the shorter and the last possible is a call to restart, it shows that capacity is too small, the battery with load ability is poor, and also to life! The above prove charging times and the battery life is to have a certain relationship! General filling a electric capacity will attenuation 1-5 ma (depending on the stand or fall of core).
Besides the new bought the phone charging time(PANASONIC DMW-BMB9 Battery)
General new buy the phone will be informed that the three twelve hours filling, must be finished filling again! The idea is to stay in about 98-2000, when most of the cell phone battery is nickel metal hydride battery, have memory effects! That is the nimh batteries in useless over electric power is charging, might remember situation, that didn't put out that part of it may be lost if not to do so might affect the battery of standby time, now a few call all the mobile phone use lithium ion battery now, does not exist have memory effects, say in the production of the battery will have at least 1-2 times charge-discharge, sold into our hands, the battery is activated, sure, twelve hours without charge, as for a few times before standby time slightly shorter that is normal, because the battery after a period of time capacity will have loss, filling put several recovery!
Besides charging methods (PANASONIC DMW-BCF10E Battery)
Normally will last one case electricity use up, cellular phone to start alarm can charge! Don't need to be automatic shutdown to filling! Because when the battery voltage alarm has been close to the automatic shutdown voltage! Charging tip can not only full! It need not long time filling, of course, have been filled, it doesn't matter, because the cell phone battery is protection board, full automatic stop after won't fill! But some fake except battery, a lot of false battery protection board is empty, doesn't work.
Due to the nature of a digital camera, they need a lot of voltage and also need to keep good battery long periods of inactivity digital camera rechargeable batteries to a big hit, many current digital camera has a flash, may also make a short film, the two characteristics is very good, but can drain battery two times normal speed, photo shooting.
Most people are familiar with basic rechargeable battery, but the key to finding a good a doctor to give your digital camera is to look at the battery material, how will charge, and how long will the cost in use and sitting on the shelf or in the digital camera.
A little I look in my purchase any digital camera I buy is to ensure that there is a common battery size. The reason is, no matter how you plan a photo shoot, things happen, you may have to resort to the old alkaline batteries solve your problems, then. Panasonic battery my first choice is a rechargeable battery, but you never know, this is a very good thing can find a new set of batteries.
There are several important factors to consider, rechargeable batteries is the best. The first is the amount of voltage, followed by long time, then the battery of the time; Four is charge (how long shelf life will be held responsible for the storage battery).
Here are a series of typical rechargeable batteries and their voltage output:
Ni-Cad rechargeable battery, 12 volts
Nickel metal hydride rechargeable batteries-1.2 to 1.5
Ni-ZN rechargeable batteries-160 volts
Standard alkalines is 1.5 volts
Also have a level a reference number of energy storage, from the ability to represent called milli ampere hour. These level general fleeing to 2100 from 750 from is high, the more the number of the battery capacity (higher digital better).
The Ni-Cad and nimh most common, almost every major brand battery multiple versions. The latest technology is Ni-ZN are excellent storage capacity and long shelf life. Many types of rechargeable batteries can be charging many times, but they didn't mention that drop down power amount of recharges x.
And this is the real factors to consider. Let us say that if you find new battery you can use about 100 photos before they go to the south. Recharges Numbers increase, reduce many pictures. Some can only continue to before they start, recharges loose the ability to completely costs. Clever cost is still good savings from an ordinary AA alkaline battery cost $1.15 and the comparable charge is $2.50, according to the figures from $5.00.
Recent Ni-ZN cost about $5 each request and take over 500 recharges in any losses before the injury charge ability. But they also play more voltage so for example your flash recycling half the time to complete the normal alkaline batteries. If you have 100 threw a set of alkaline, you should get at least 175 vote of Ni-ZN are the same size. Plus storage life N-ZN than any other choice.
Rapid turnover a flash can be a big problem, because it is a very painful, but when photographs in the interior, need to wait for two minutes of the flash is full of power. Or, if you are shooting a series of short a minute video and ran out of the juice in the middle is not a good thing.
So, based on the pricing and ability, if you can recharge the battery is more than 500 times more the highest price, they use more cheap long-term development. If they hold up close to claim 500 cost, well, you can do the math. This is a no brainer, Ni-ZN provide more voltage, better life, and more fees each battery.
