1.MP3Life of lithium battery

It's like a cell phone lithium battery.MP3The life of a built-in lithium battery is deep and deep filling300-500Time or so (national standard), that is to use about one or two years or so, the play time will be significantly shortened, and some even completely unable to start the machine, then you must replace the new battery to use. Almost all of them are not used for after-sale service. In order to reduce costs, they are used in the installation process.BBatteries (faulty, defective, and high-grade products in factories) may suffer a New decline in performance and a shorter life after three months of general use.

Two.MP3The playing time of lithium battery

The playing time is related to the battery capacity and the power consumption of the machine. The larger the screen, the more power it consumes and the larger the battery.1.2Below the inch screenMP3The capacity of the lithium battery is generally in150--300mAh,Playback time after full power8Hour or so1.5-1.8Inch screenMP3The capacity of the lithium battery is generally in300--1000mAh, 2.5Inch screenMP4The capacity of the battery is1800mAhAbout.Because there is no after sale service, in order to reduce the cost, it is used in the installation.BQuality batteries (factory defective, defective, grade), the general capacity ratio.ALow quality20%About,The playing time will be shorter.

Three, how to tell my machine is a battery problem?

If you areMP3The Bluetooth device has the following phenomenon. It must be a battery that needs to be replaced.

1It has been used for more than a year, and the time for playing (standby) is obviously shortened.3Hour or so, indicating that the battery capacity is reduced and the service life is up.

2Unable to turn on or power down: the battery is short circuited or is not of good quality. The gas is rising or the internal resistance is increasing. The battery has failed.

3The broadcasting effect is worse: the internal resistance of the battery increases and the output voltage is too low.

4It can not be played at all: Battery ring or protection circuit ring, battery failure.

Be careful:MP3If the start is normal, then it is found that there is a fault.90%The above is the battery reason, because other electronic component rings are less likely, and the battery is consumable, the quality is uneven, and the charger is generally high output voltage, not the limited pressure for lithium battery.4.2V)function,Completely protected by battery line,Easy to damage.A great valueMP3It's very unpleasant to use because of a small battery.!

Four. How do you know the battery model of the machine?

1, open the machine: to boldly open the machine, MP3 inside is actually very simple, do not worry that it will damage the machine. Check the machine carefully, see if there is a screw, there is a small screwdriver to open it, no one is generally the shell glued or a buckle, with a knife along the seam after a week can be opened or warped, a careful point, the general shell will not damage, attention to key buttons and so on.

2, open to see the battery, if the battery is silver, it is the polymer lithium battery, the outside is aluminum plastic film packaging, if other colors are steel shell or aluminum shell lithium battery, the outer skin is PVC plastic sleeve, blue color, and black.

3, look at the battery model: the general battery is sprayed with the model (in fact, the size of the battery), record the above words can, if the size is not used to measure the length and thickness, record.

Five. How do you buy the battery you need?

First disassemble the battery to see the battery (self will detachable, not to find the maintenance technician dismantling), most of the batteries are marked with the model, in fact, the model is the high (thick), wide, long, model of the model in the next table in the store, if not, can contact the store to match. If you still can't match it, you can use a similar model, that is, a smaller one, for example, yours is552030Not in the table, available.052030It's just high (thickness) small0.5With a piece of thick0.5The piece of paper is put up to prevent shaking in the machine, such as the machine has space, otherwise it can find a larger one. If the battery does not have a model, or can't see it, it is easy to use a ruler to measure the length, width and height. Then the same method is found in the table. The size is not considered, and it can be matched. Another point is that a few machines are not used for lithium batteries, and the voltage is not.3.7 (3.6) VA,Maybe it is1.2Vor2.4VA,The owner must be consulted.

Six. Replace the battery

The red line of the battery is the positive electrode, the black line is the negative electrode. Weld the original battery and the new battery according to the original position of the positive and negative electrode. If you can do it yourself, you can't do it by yourself. If you have electric soldering iron outside, you can ask the master to help you.

Reminder:Please check the goods first when receiving the goods.,Whether or not it is broken,Not to sign up for the above problems,Or refuses to accept,The signature is equal to that you have affirmed the goods.,To avoid a dispute!!!!!!

Because the surface materials of polymer batteries are easier to scratch, buyers who can not accept them do not buy them. The battery is brand new and the wires are not welded.

The battery series is sold at zero profit. If there is any repurchase and replacement, the buyer must pay the freight back and forth.
