= Battery Introduction =

A ， 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 products ) ， 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 machine \\\'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 machine 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
