= Battery Introduction =

One , MP3 lithium battery life

Like lithium batteries and cell phones , MP3 built-in lithium battery life is generally deep charge deep discharge is about 300-500 times ( GB ) , which is about a year or two after use , playing time will be significantly reduced , or even completely unable to boot using then you have to replace the battery before use. Almost all of the brand-name computers because no service , in order to reduce costs, which in the installed product using a B cell ( factory defective products , defective , grade product ) , battery performance may be three months after the general use of the straight-line drop a shorter lifetime .

Two , MP3 lithium Duration

Playing time and the battery capacity and the size of the mhine \\\\\\\'s power consumption , the greater the more general screen power consumption , the battery is also larger . MP3 capacity lithium battery 1.2 -inch screen in the following general 150 - 300mAh, after a full charge in about 8 hours playback time capacity lithium battery , 1.5- 1.8 -inch screen MP3 is generally 300 - 1000mAh, 2.5 -inch screen MP4 battery capacity of about 1800mAh. hodge mhine because no service, in order to reduce costs, when installed inside a battery with a B grade ( factory defective products , defective , grade product ) , generally lower capacity than a product about 20% , the playback time will be shorter .

Third, how to judge my camera battery problems ?

If your Bluetooth device has the following MP3 phenomenon , is scheduled to be a problem with the battery , replace :

1 , the use of more than one year has play ( standby ) time is significantly shorter ( about 3 hours ) , the battery capacity is reduced to life .

2 , can not boot , or power : battery internal short circuit or poor quality of the hair and blow up or resistance becomes larger , the battery fails .

3 , playback worse : battery internal resistance increases , the output voltage is too low .

4 , can not play : battery protection circuit ring or rings , battery failure .

Note : MP3 if the start is normal, and later found to have a fault , it is more than 90 % of the battery causes the chances for other electronic components smaller ring , while the battery is a consumable , uneven quality , and with charger the output voltage is generally higher , the pressure is not limited dedicated lithium (4.2V) function relies entirely on the battery line protection , easily damaged . MP3 valuable one because of reasons not to use a small battery is very bad mood !

Fourth, how do you know the mhine \\\\\\\'s battery model ?

1, open the mhine : To boldly open the mhine , MP3 interior is very simple , do not worry it will damage the mhine . Carefully check the mhine to see whether the screw , there it can be opened with a small screwdriver , housing in general is not bonded or have snap buckle , and after a week with a knife along the seam can poke or scratch Alice opened carefully, generally will not be damaged shells , buttons and other attention .

2 , you will see after opening the battery if the battery is silver , then the lithium polymer battery , the outside is plastic film packaging , if other colors are steel or aluminum lithium battery , the skin is PVC plastic put , the more blue , but also black.

3, see Battery Type: Battery are sprayed with a general model ( in fact represented battery size ) , recorded atThe word can be, if not with a ruler long look generous , is recorded.

Fifth, how to buy the required battery?

First disassemble the mhine to see the battery ( will dismantle their own self- demolition , repair technicians will not find a split ) , most batteries are marked with the model , in fact, is the battery type high ( thick ) , width, length , there are models in Our table below for the model , if not on , you can contact the restaurant to go with . If you still with less , you can use a similar model , which is similar to a small point , for example, you are 552 030 , not in the table , the available 052,030 , but the height ( thickness ) small 0.5 , with a piece of thick paper 0.5 piece put up loaded up in the mhine to prevent shaking, as the mhine has a space , whereas a similar point can be found large . If the battery is not the model , or do not see , is simple, with a ruler to measure the length, width , height , and then from the table, according to the above method to find similar capacity size should not be considered able accompanied on the trip. Another point is that the mhine is not used for a small number of lithium battery , the voltage is not 3.7 (3.6) V may be 1.2V or 2.4V , you must contact the owner .

Most types of batteries have not sprayed the word body type, V number, capacity, etc., mind do not buy!
Tips: Voltage 3.7V-4.2V batteries are common to all we can correspond to a good size buy!
