If you never go out and take more than 300 photos, lithium-ion is better, after all, do not have to match the other batteries, more than the purchase of a piece of original lithium-ion cost a little higher. You can think about, you often go out before you forget to fill the battery? Is it inconvenient to charge the battery when you are traveling? This can easily bring you regret on your trip.
There are also some AA batteries that are more power hungry, such as Kodak's lower-end machines, and this will depend on the amount of shooting you do.
Specialized models, such as the Kodak 7440 and so on, actually can be universal NOKIA lithium, compatible with the battery cost is quite low.
And you need to understand clearly, some models can not only use AA batteries, can also use lithium, just ask clearly.
AA batteries have the advantage of being readily available, and you don't have to worry about running out of batteries at any given time
Lithium batteries have the advantage of durability, but the disadvantage is that the original price is high, and you have to look for a place to recharge the machine when it runs out of power.
AA rechargeable batteries several defects:
1. short life
Most of the rechargeable batteries in the 100 times after the end of the life of the end of the rechargeable batteries, and charging power with the time less and less
2. heavy weight
4 AA rechargeable batteries than lithium-ion batteries are twice as heavy
3. fear of cold
AA rechargeable batteries in -3 degrees Celsius weather conditions, the temperature of the battery is very high. rechargeable batteries in -3 degrees below the weather freeze once is finished
Lithium is -10 degrees
4. poor cruising ability
Good lithium can shoot 1500-2000 pictures, good Sanyo 2800 rechargeable batteries can shoot 500 -700 sheets, so 1 lithium = 8 2800mh Sanyo batteries
5. use limitations
AA rechargeable batteries must be used up before charging, lithium can be flushed at any time
6. charging time is long
AA fast charging is very hurtful to the battery, 80% of the users of the fast charging, the battery is about 70 times in the The life of the battery is about 70 times. Lithium two hours can charge 70%
7. charger big
AA chargers are generally very large and heavy, lithium chargers are relatively light
Advantages:
1. AA charging price is low
Sanyo charging kit 2800MH price of 280 (recommended to buy the imported Sanyo, the quality of the inner core is much better than GP or Ruineng much better)
Imported lithium price 280 (strongly recommended to support the domestic lithium, the price of 90 yuan, capacity than imported lithium, and the service life is comparable)
2. Outside the alternative
You can buy 18 yuan Duracell batteries instead of the battery, you can continuously shoot about 40-80 pictures
As for shooting halfway without power, using AA rechargeable generally buy 8 batteries.
The use of lithium recommended 90 yuan to buy a domestic lithium
So lithium batteries are good, fast charging (two or three hours can be full), back to the power fast, no memory effect (can be used with charging), small, lightweight, charging equipment is also compact and portable, and the price is not expensive, a compatible battery as long as dozens of dollars, and is not difficult to buy. As for emergencies, you don't have to worry about them as long as you have a spare battery.
The following description of the two types of batteries:
There are generally two types of digital camera power supply: lithium-ion batteries (referred to as lithium-ion) and AA batteries (AA batteries)
Many people buy a digital camera, it is not clear whether to buy lithium-ion good, or to buy a good battery of 5 (generally rechargeable nickel-metal hydride batteries)
So let us briefly analyze the differences between them!
1. Specialized supporting lithium-ion batteries, with fast charging, generally about three hours, flash charging relatively fast, accurate power display and other advantages, the advantage of its small size, you can match the shape of the camera, made more compact and stylish. Disadvantages are: expensive, buy a second battery is not convenient, not universal, etc.
2. The use of No. 5 battery camera: that is, AA batteries, generally two and four kinds of two, the advantages are: No. 5 batteries can be purchased anywhere, versatility, there are many choices, another purchase of batteries is not subject to the original specifications of the limitations of the purchase of rechargeable batteries, the purchase of the capacity of the rechargeable batteries are also more choices, and its disadvantages are: when the camera for the two batteries, the flash charging Slow, when using ordinary batteries, generally can only take a dozen pictures of the battery is dead, only the NiMH rechargeable batteries are more suitable for the camera, no power display or display power inaccuracies.
The advantages and disadvantages of each, so the conclusion is very simple: if you prefer that camera, it does not matter which kind of battery is, lithium can buy more than one spare.
For example, the Kodak V550, which was popular in 2005, is compact, has excellent performance, and is a good cameraman, but the lithium batteries it uses are very unreliable, so it is essential to buy an extra battery.
Reference data: V550 fully charged can shoot about 150 pictures (a small portion of the flash)
Again, for example, Canon's A-series, with all the 5 batteries, this series of cameras catering to beginners, full manual functions, the price of cheaper 5 batteries, and thus cost and cost-effective are satisfactory, the cost of the accessory battery, this is not a lot of money is a priority for the people.
Reference data: Canon A520 two Pinsent Masons 2200mah nickel-metal hydride batteries, fully charged can shoot about 300 pictures (a small portion of the flash)
(The above reference data, not absolute data, including the middle of the browsing and playback and other actions, turn off the LCD and do not use the flash can shoot more)
In 05 years with lithium digital cameras also have a good battery life. The endurance is quite good machine, such as Fuji F10, etc., they claim is only with a battery out of the travel are not afraid.
Many high-end cameras also use AA batteries, perhaps the professional is also afraid of running out of power! If the battery is dead, you can buy alkaline batteries anywhere to replace them.
Note:
Lithium
Lithium batteries are generally very good quality of the original factory, the best to provide a lithium when the best to buy back to the original factory, or to buy brand-name, do not be greedy for cheap and buy substandard goods. In order to prevent future battery bad or lost can also buy the same battery, it is best to choose a brand-name camera, so that within a few years do not have to worry about the closure of the manufacturer and no battery to sell.
Lithium batteries are generally simple to use and the chargers are customized, so there are relatively few problems.
Theoretically, the number of times a lithium-ion battery can be recharged is less than that of an AA Ni-MH rechargeable battery: 500 times or so / Ni-MH is 500-1000 times or so
Reasonable use to achieve the desired number of times, do not charge half of the battery to take it out or use it halfway to recharge it.
Recently, Pinsent Masons for the more popular digital camera production of lithium-ion, the quality is also good, so buy the star machine is also a better choice, an original battery, more with a domestic quality is also a good price reasonable battery is also a wise choice.
(Note: the star machine is the year a brand manufacturers are also the best-selling models)
Buy a battery to choose a reputable business is also very important to avoid buying fake.
AA rechargeable batteries / 5 nickel-metal hydride batteries
There are a lot of such batteries on the market, making it difficult to know which one to buy.
Buy domestic, afraid of the quality is not good, buy imported and expensive.
Imported batteries are better known as Sanyo, but there are many fakes, so it is recommended to go to a big mall to buy.
Domestic nickel-metal hydride batteries can be completely comparable to imported batteries, cost-effective
Here is a recommendation for domestic batteries: Pinsent Masons nickel-metal hydride rechargeable batteries
The above batteries I've used, I feel good, and the price is fair
Buy nickel-metal hydride rechargeable batteries should also pay attention to the following things:
1. You buy the set or buy a single battery and then buy chargers
If you buy a set of batteries and charger, then buy the charger.
If you do not have a charger, it is recommended that you buy the set, the set generally have four batteries and matching charger
Batteries are best equipped with the original charger, because only the original manufacturer to understand their own battery
2. buy a high-capacity batteries,
Generally marked on the battery body, the bigger the better the number, 2000mah: that capacity of the battery, at 2000mA discharge, the battery can be used in the battery. The battery, in the case of 2000 mA discharge can be discharged for one hour, digital cameras are recommended to buy more than 1800mah, general 5 nickel-metal hydride battery capacity does not exceed 2500mah, more than that is a lie to you, here we recommend that you buy Pinsent Masons 2300mah fast and easy charging set.
3. It is recommended to buy a fast charger, such as the Pinsent Masons Quick and Easy Charger
Why? Some say standard charging, full charge! The battery is durable!
General nickel-metal hydride battery charging 500-1000 times the life of the charge, according to a week of charging can also be used for many years, so do not worry about the battery life, the standard charger is 200ma current charging 18 hours, charging a charge to be a day of your time, the time is valuable it, if you think that is not, then you buy the standard charging
Pinseng fast and easy to charge! 2200mah, 5.5 hours to charge four particles, 3 hours to charge two particles, think about it can let you save a lot of time
The low price of the standard charger is not charging full of prompts, fast and easy to charge a full of power automatically stop charging, Pinsent Masons fast and easy to charge, charging state is a flashing red light, full of red light is always on, with the prompts and timed to protect the not afraid of overcharging, from this point alone you should be used!
Lastly, please use the 5 battery camera users: do not think that Nanfu or Duracell power is very high in the camera should be able to take a lot of photos, this idea is not quite right
Nowadays, non-rechargeable batteries are absolutely no rechargeable nickel-metal hydride batteries current is large, the digital camera is a high-current appliances. As you know from physics, the resistance of a series circuit is directly proportional to the voltage, and the digital camera is connected in series with the battery pack.
Nickel-metal hydride rechargeable batteries, in the power has been consumed in the process of keeping the internal resistance change is relatively small
Alkaline batteries after the consumption of the power of the internal resistance increase is relatively obvious, so with high-current appliances (digital camera internal resistance is small) internal resistance ratio increases, the battery poles of the voltage will be large, two aspects: 1 allocated to the appliances of the voltage becomes smaller; 2 their own power consumption Increase. And cause alkaline batteries still have power, digital cameras can not shoot the false image, many people also come up with this theory: this machine really sucks ...
And the capacity of NiMH rechargeable batteries is much larger (depending on the battery you buy), so:
It's not surprising that you can take 30 pictures with a NF high-powered alkaline battery in a digital camera, but you can take 300 pictures with a 2,000mah Pansum NiMH battery.
It is recommended that you buy NiMH rechargeable batteries instead of ordinary batteries, non-rechargeable batteries can be used as an emergency when you are out and about, there is no charging outside and the charging time needs to be long, which is a no-brainer.
One rechargeable battery = 1000 non-rechargeable batteries? Save money and protect the environment.
This is not to say that NANFU alkaline batteries are not good, but the use of different occasions, such as electronic watches, silver oxide batteries, silver oxide batteries due to the slow discharge, a few years are still electric, but the current is very small, so the general use of the current is small, the need for a long period of time on the electrical appliances, such as clocks and watches, motherboards, timing, etc.
On the maintenance of the battery
1. Several times after charging and discharging in order to achieve the best state, be sure to look at the battery charging instructions, generally 3-5 times after charging in order to achieve the best state, and each time the charge is full of appropriate, should not be charged for too long, some people think that put the charger in the charger for a few more hours will be more full of some of the rumors are sometimes incorrect, even if it is the salesman to tell you, the same, look at the instructions.
2. Most people don't pay much attention to cleaning the battery. To avoid problems with power loss, keep the contact points on both ends of the battery and the inside of the battery cover clean. If necessary, wipe gently with a soft, clean, dry cloth. Never use cleaning or chemical solvents, such as thinner or solvents containing alcohol, to clean your digital camera, battery, or charger. In addition, before charging, use a soft, dry cloth to clean the contact points on both ends of the battery and keep them as clean as possible to ensure that the battery is fully charged. If the battery electrode is oxidized, wipe it off, and if it is severely oxidized or peeled off, replace it with a new one immediately.
3. If you are not going to use your digital camera for a long time, it is important to remove the battery from the digital camera or charger.
Lithium-ion batteries can be half-charged and stored for a long time without using them, and then activated again when they are used again (after several times of charging and discharging like new batteries)
Nickel-metal hydride batteries should be fully charged when they are not used for a long time and then stored for a few months before being filled up to avoid over-discharging
Theoretically, nickel-metal hydride batteries have a much longer lifespan than lithium-ion ones; lithium-ion ones are used for 500 times, nickel-metal hydride for 500-1000 times, and nickel-metal hydride for 500-1000 times. 500-1000 times, I heard that the new Nanfu has 1200 times.
4.5 nickel-metal hydride batteries for 1.2V, just fully charged when placed at least half an hour or more before use, because just after charging the battery temperature is high voltage high, placed for a period of time to allow it to stabilize and then use.
5. Batteries do not use half and then charge, or try to use the camera to show insufficient power and then charge to extend the service life of the battery, and some people say that the display of insufficient power to shut down the battery will have to be completely discharged before charging will be better; in fact, do not need to do so, lithium and nickel metal hydride electricity have no memory effect, so there is no need to be too much to discharge and then charging, in particular, nickel metal hydride batteries, power Over-discharge will lead to permanent damage to the memory. As usual, the camera can be recharged by turning off the camera when it is low on power.
