One, MP3 lithium battery life
As mobile phone lithium battery, MP3 built-in lithium battery life is deep charging put about 300-500 times (GB), which is about one or two years after playing time will be shortened obviously, some even completely unable to boot, then you must replace the new battery. And almost all of the brand-name machine without the customer service service, in order to reduce the cost, installed in which is used to B the battery products (factory of defective products, defective, grade), the general use of three months after the battery performance may decline, shorter life expectancy.
Two, MP3 lithium battery playback time
The machine capacity and the playing time and battery power consumption is related to the size of the larger screen, general power battery is also larger. Lithium battery 1.2 inch below the MP3 capacity of 150–300mAh in general, after a full charge of playing time in 8 hours or so, the lithium battery 1.5-1.8 inch screen MP3 capacity is generally 300–1000mAh, 2.5 inch screen MP4 battery capacity at about 1800mAh. Because no brand-name machine customer service service, in order to reduce the cost, in the installed when there is a B battery (factory of defective products, defective, grade), the general capacity of goods is about 20% lower than A, the playing time will be shorter.
Three, how to judge my machine is the battery problem?
If your MP3 Bluetooth device has the following phenomenon, it will be a battery problem, need to be replaced:
1, the use has been more than a year, play (standby) time is significantly shortened (about 3 hours), indicating battery capacity reduction, service life to.
2, can not boot, or power off: the battery internal short circuit or poor quality of hair bubbling up or larger resistance, battery failure.
3, play the effect of variation: the battery internal resistance becomes large, the output voltage is too low.
4, can not play: Battery ring or protective circuit ring, battery failure.
Note: MP3 normal if the start is later found to have fault, is more than 90% of the battery is due to other reasons, electronic components are less likely to ring, and batteries are consumables, quality is uneven, and the distribution of the charger is generally higher than the output voltage, battery special limited pressure (4.2V) function. Completely rely on cell line protection, easy to damage. A value of MP3 for small cell reasons and cannot use is very uncomfortable!
Four, how to know the machine battery?
1, open the machine: daring to open the machine, MP3 is actually very simple, do not worry about damage to machine. Carefully check the machine, to see whether there are screws, with a small screwdriver can be opened, the general is no shell bonded or there is a button on the card, with a knife along the seam a week after they can open or open up, careful, general shell will not damage, attention key.
2, open will see the battery, if the battery is silver, the polymer lithium battery is outside the plastic film package, if other color is steel or aluminum shell lithium battery, the skin is PVC plastic sleeve, blue are also black.
3, look at the battery model: general batteries are sprayed with models (in fact, is the size of the battery), the words can be recorded under the above, if you do not use a ruler to measure the length of generous, recorded.
Five, how to buy to the battery?
First open the machine to see the battery (you will not find their own demolition demolition, demolition, maintenance and technical personnel) most batteries are marked with the type, the battery model is actually high (thick), wide and long, a type in the shop under the table of the model, if not, can contact the shop to go with. If you still don’t deserve to, can use similar models, for example, is similar to a small one, and you are not in the table, 552030, available in 052030, only 0.5 small height (thickness), with a thickness of 0.5 pieces of paper put up and to prevent sloshing in the machine, such as the machine has space, but can be found close to a bigger. If the battery does not model, or can not see, but also 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, can match on the line. Rather small, not super, because once the check is not installed, freight than the battery itself is also expensive. Another point is a machine is not used in lithium batteries, the voltage is not 3.7 (3.6) V, may be 1.2V or 2.4V, to contact the owner.
Six, replace the battery
The red cell is positive, black is negative, the original battery welding, some of the motherboard is not marked with “+” and “-” pole, the best mark in welding down before the new battery. According to the original negative pole position welding on it. If you do not have iron can be on the outside, as long as the electric iron place (maintenance) to help find the master point on OK.
