Model: For Onda V975M battery capacity: 12000MAH rated voltage: 3.7V, charging voltage: 4.2V 59 yuan
8000MA 46 yuan.
Note: This is a new battery, not welded, suitable for a variety of mobile phone batteries, learning machine batteries, e-book batteries
Generally, the life of the built-in battery is about 300 times of charging and discharging, and it will be aging, but the battery's own protective plate is good.
Users with DIY hands-on capabilities can change their batteries by hand, uncovering the adhesive tape in front of the primary battery, which contains a long strip circuit board.
This is the protective plate, the battery output line is generally welded on the protective plate P + P - and the positive and negative poles of the battery are welded on the protective plate B + B -.
Use the iron to solder the positive and negative electrodes of the battery, and then solder the new electrodes to the normal negative electrode for OK.
This requires a certain amount of DIY hands-on capability, and requires some tools. Please evaluate your hands-on ability before buying.

I. life of MP3 lithium battery
Like mobile phone lithium batteries, MP3 built-in lithium batteries generally have a life of about 300-500 times deep charge (GB), that is, after about one or two years of use, the playback time will be significantly shortened, and some can not even be turned on at all, when you have to replace new batteries to use. Almost all of the miscellaneous machines do not need after-sales service. In order to reduce the cost, they use B-type batteries (faulty products, inferior products, grade products in factories) when they are installed. After three months of general use, the performance of the batteries may plummet and the life of the batteries will be shorter.
Two, MP3 lithium battery playing time
Play time is related to the capacity of the battery and the power consumption of the machine. Generally, the larger the screen, the more power consumption, the larger the battery. The lithium battery capacity of MP3 with 1.2-inch screen is usually 150-300 mAh, playing time is about 8 hours after charging, the lithium battery capacity of MP3 with 1.5-1.8-inch screen is generally 300-1000 mAh, and the battery capacity of MP4 with 2.5-inch screen is about 1800 mAh. Product B batteries (faulty, defective, grade) generally have a capacity of about 20% lower than that of product A and a shorter playback time.
Three, how to tell my machine is a battery problem? <
If your MP3 Bluetooth device has the following phenomenon, the battery must be replaced.
1. It has been used for more than one year, and the playing (standby) time is obviously shortened (about 3 hours), indicating that the battery capacity is reduced and the service life is up.
2. Can not turn on, or power down: the battery short-circuit or poor quality of the internal bloating or internal resistance become larger, the battery failure.
3, the broadcasting effect is worse: the internal resistance of the battery increases and the output voltage is too low.
It can not be played at all: Battery ring or protection circuit ring, battery failure.
Note: MP3 if the beginning is normal, and later found fault, then more than 90% of the reasons for the battery, because other electronic components are less likely to ring, and the battery is consumable, uneven quality, and equipped with chargers are generally high output voltage, not lithium-specific limited voltage (4.2V) function, complete Battery line protection, easy to damage. A valuable MP3 because of small battery reasons can not be used is very uncomfortable <
Four. How do you know the battery type of the machine?
1. Turn on the machine: to boldly turn on the machine, MP3 internal is actually very simple, do not worry about damage to the machine. Check the machine carefully, see if there are screws, there is a small screwdriver can be opened, there is no general shell is glued or there is a buckle on the knife, with a knife along the sewing a week can be opened or warped open, careful point, the shell will not be damaged in general, pay attention to buttons.
2. After opening, you will see the battery, if the battery is silver, it is polymer lithium battery, the outside is aluminum plastic film packaging, if other colors are steel or aluminum shell lithium battery, the outer skin is PVC plastic sleeve, blue more, also black.
3. Look at the battery model: Generally, the battery is sprayed with a model (in fact, it is the size of the battery). Record the words above. If you do not use a ruler to measure the length and width, record them.
Five, how to buy the battery you need?
First of all, take apart the machine to see the battery (I will take apart from myself, will not find maintenance technicians to take apart), most of the batteries are marked with models, in fact, the model is the battery high (thick), wide, long, a model in the shop table below the model, if not, can contact our shop to match. If you still can't match it, you can use a similar model, that is, a smaller one, for example, your 552030, not in the table, can use 052030, but the height (thickness) is less than 0.5, with a piece of 0.5 thick paper put on it to install, in order to prevent the machine from shaking, such as the machine has space, otherwise you can find similar large. A little. If the battery does not have a model, or can not see, is also simple, with a ruler to measure out the length, width, height, and then from the table, according to the above method to find similar, capacity size do not consider, can match on the line. It's better to keep it small, because once it's too big to be loaded, the shipping cost is more expensive than the battery itself. Another thing is that a few lithium batteries are not used, the voltage is not 3.7 (3.6) V, it may be 1.2V or 2.4V, and the shopkeeper must be consulted.
Six. Replace batteries.
The red line is the positive electrode, the black line is the negative electrode. Weld the original battery, some motherboards are not marked with "+ -" electrode, it is better to make a mark before welding down. The new battery can be welded to the original position of the positive and negative electrode. If you can't do it without ferrochrome, you can get help from your master in the place where there is electric soldering iron outside. /p>
If you want to do it yourself, you can buy our hand-held ferrochrome for only 25 yuan. It can also be used as a spare for future electronic digital maintenance. See item.taobao.com/item.htm?Id=2025648030 for more details.
For every friend who buys ferrochrome to prepare his own welding, we will also give you one meter tin solder and a box of rosin./p>.
