Introduction of advantages and disadvantages of various MP3 lithium batteries

The growth of the current MP3 market continuously increases. MP3 consumption group is becoming more and more. However, when choose and buy MP3, people often have such doubt: "does built-in MP3 lithium battery OK?" "Which battery is more appropriate, AAA battery or AA battery?" Thus, MP3 power solution is one of the main factors influencing people to choose a battery.

Currently, MP3 power solutions with built-in lithium battery, lithium battery can be divided into the liquid according to the internal structure and way of use lithium ion batteries、Polymer lithium ion batteries, and built-in lithium battery, the removable type lithium battery, etc. Below is the MP3 do specific analysis the merits and demerits of all kinds of lithium battery.

Analysis on the advantages and disadvantages of lithium-ion batteries:

1 > the advantages of lithium battery:

Relative to the nickel metal hydride batteries, lithium batteries with high working voltage, large energy density, low self-discharge rate, no memory effect, etc. In addition, the lithium battery can be done to be thinner and smaller, it is reported that polymer lithium ion batteries are only 0.5 mm, the thinnest and the characteristic of any size and any shape, also greatly improve the flexibility of battery design, in order to meet the needs of the product, made into any shape and the capacity of the battery.

2 > the shortcoming of lithium battery:

Any battery can't be perfect. The lithium battery is not exceptional also, two years before the outbreak of the Ipod's battery door "events, Meizu X6 just listed soon received complaints about the battery case, to a large extent also hesitant to buy lithium battery of MP3 players. To sum up, the lithium electricity have a weak side, can't overcharge, giving excessive discharge cannot bear high temperature, cold. These are its weaknesses. These just in spite of his flaws, however, the advantages of lithium battery is obvious, it's no wonder so many manufacturers willing to for its products with lithium battery.

However the broad consumers to lithium batteries still don't know much, there are still many misconceptions in understanding and the use of the most common is the lithium battery life and the life of the MP3.Actually, in terms of currently used lithium electricity scheme of machine, there are certain differences, such as removable lithium battery and built-in lithium battery is the biggest difference between the two.

1 > removable lithium battery

A removable lithium electricity, is the battery can be free replacement, especially go out to use, very convenient, is a collection of economic and environmental protection in one, fully consider the human problem, the color screen MP3, MP3 battery life increasingly valued today, slowly began to popular market. By the battery type, removable lithium batteries and can be divided into special and removable lithium battery is compatible with Nokia battery two kinds.

Low compatible with Nokia battery

As the name implies, is compatible with Nokia battery first hand machine indicates that the world brand Nokia mobile phones support the battery can be applied to the MP3, this design in addition to the advantages of both removable lithium electricity design, but also has stronger commonality, buy low cost advantages, is very popular with consumers.

Low removable lithium battery

Removable lithium power battery is lithium battery although removable, but the battery specification is only applicable to the machine, so the generality is not strong, is not easy to buy, and the price is not transparent, consumers are likely to pay the extra cost. At present, the design of the battery is not much, everybody is familiar with ZenMicro iriverH10, SONY HD5, innovation, etc., these products are generally only with a battery, additional purchase frequently hundreds of yuan, is not the average consumer can afford.

2 > the built-in lithium battery

Is the so-called built-in lithium electricity, lithium battery is installed in the inside of the chassis, only unwrapped chassis, to see the inside of the lithium battery. The advantage of this design is not frequent replacement battery, as long as the plug in the charger, when there is no electricity or connected to the computer USB port can charge automatically. And disadvantage is once the battery is damaged, it must be hired to replace, and because the internal battery is not circulate on the market, users are likely to pay a huge sum to replace the battery.

Actually, either built-in or replaceable type, lithium battery is very convenient in use, don't have to worry about memory effect, can charge at any time, using lithium electricity machine battery life is usually more enduring, thin volume is smaller, more personality. As long as the daily specification to use, can completely avoid the unpleasant things, prolong service life.

The correct use of lithium battery should pay attention to the following:

1. New batteries do not have to "activate" 12 hours of charging for a long time, this method applies only to nickel cadmium nickel-metal hydride batteries, for lithium electricity more harm than good.

2. Long time no use need to charge storage again, and every once in a while to charge.

3. "deep charge deep discharge" to the lithium battery has no meaning, and easy to damage.

4. Try to avoid overheating in a cold environment to use lithium battery.

In addition, many people worry about the service life of the built-in lithium electricity MP3 problem, in fact, although the lithium battery charge is only 300-500 period, but it is not only to charge and discharge of 300 ~ 500 times. A charge cycle means that all the power battery by full use empty, again from empty to full filling process. This is not the same as to charge.
