How do you choose and buy lithium-ion battery properly?

Why not the battery of Mobile phone having long cycle life? It is likely that the manufacturer oversize battery capacity. Why is there electric shock in the process of charging? It Is likely to be fake charger that has unqualified insulation. Li Shan, Jiangsu Bureau of Quality and Technical Supervision's  engineer,  reminded consumers after the product spot-check results of several factory that it had better not using the cell phone during charging, and the charging time also should not be too long, which is generally for 2 ~ 5 hours.

Take a look at their investigation of mobile phone battery test results as below:

The test mobile phone, a total of 45 units, there are international brands such as Apple, Samsung, Nokia, domestic brands such as Xiaomi, TCL, Lenovo, BBK, device's battery of 35 units, retail cell phone accounts for 10 units. Bring their own cell phone batteries, 29 batch of qualified and 6 batch of unqualified. Retail cell phones 4 batch of qualified and 6 batch of unqualified. Whether their own or retail battery, they are not qualified reason for battery capacity is not up to standard. In accordance with the Quality Bureau standards, mobile phone battery discharge performance shall be not less than 5 hours. However, the monitoring of unqualified battery this time discharge are all less than 5 hours.

Why they oversize the battery capacity?Hours used batteries and battery duration of a mobile phone is one of the important evaluation indicators. And the buyer has no professional equipment to test battery, so they don't know the actual capacity of battery. The manufacturer exaggerates a larger battery capacity, using a false advertising to induce consumers to buy their products.

Li analysis points out: "smart phones consume a lot larger than functional phone. Specially  small size mobile phone, standby time is shorter. But the factory battery since the match quality qualified rate is high, relatively safer, but the price is expensive. Prices is more affordable in retail mobile phone battery relatively original battery, but the quality of good and bad are intermingled. Once bought the batteries of a few small manufacturers, their performance is not guaranteed. Not only the using time is short, may also exist certain damage for mobile phones, eventually damage the interests of the consumers themselves."

So how do consumers choose and buy the lithium-ion battery?

Li reminds, the consumer when buying electronic products such as mobile phones and charging accessories, need to confirm the network access license and CCC label.Network access license logo have blue or green checker, which is printed twice.Many false network access license logo with only one printing, unable to render double background.In network access license logo words below a clear words, the forged network access license of marks generally very fuzzy.Inspection CCC marks available fingers rub marks, formal logo should not rub off.

When consumer is buying spare battery, customers should choose formal manufacturer products. Battery specification should be consistent with mobile phone specifications. It is better to buy original battery.When choosing a mobile phone battery, do not be blind to the large capacity of Lithium power battery, try to choose the regular brand of mature products.

In the end, Li warns customer again, never buy the charger for the eagerness to get things on the cheap. The charger should be paid attention to the good feeling hand induction not coarse when choosing and buying. The good standard is the feeling of shell very thick pinch, when hard with ours fingers pinched charger shell.Whether to buy mobile phones, or charging accessories, customers should go to the big formal stores as far as possible.Keep the purchase invoice and warranty card, if the problem occurs later, those can be used as a demand compensation from the merchant.
