General, genuine mobile phone batteries should be over-current protection device internal, external short circuit current as a result of the case is too large, automatically cut off the circuit, so as not to burn or damage the device; In additional lithium-ion batteryASUS Laptop Battery COMPAQ Laptop Battery over-current protection circuit, when using non-standard electrical , Electric current will be automatically cut off when too much power, resulting in charge do not enter, in normal circumstances the battery can be automatically restored to the conduction state. If we in the process of charging, the battery found in a serious fever, or smoking, or even explosion, the battery is definitely false.
7, a close look at security signs. Such as stickers hidden under the ramp NOKIA printed words, is one of the tips. Clear is the original product flawless; eclipse is produced counterfeit. If the scan may also be found in manufacturer's name. For example, Motorola batteries, it's anti-counterfeit trademarks are diamond-shaped, and from whatever point of view, can flash a three-dimensional effect, while Motorola, Original and printing and clear, then it should be genuine. On the contrary, once the color of dark, three-dimensional feeling inadequate, vague words, there may be fakes .
8, measuring the battery charge voltage block. If Ni-Cd, Ni-MH battery block counterfeit lithium-ion cell phone battery block, it must be composed of five individual cells, a single battery charge voltage not more than 1.55V, the battery voltage does not exceed the total block of 7.75V. When the battery charging block when the total voltage is lower than 8.0V, there may be nickel-cadmium, nickel-hydrogen batteries.
Maintenance of mobile phone batteries
Mobile phone battery charging and maintenance should be started first. The first charge on the battery life after a great influence on the general requirements for the first time charge for 16 hours (if the batteries are exhausted should), but remember not more than 24 hours, or they may be to charge a bad battery. Charge after every use requires recharging every 5-6 hours. For new batteries, after several charge and discharge to achieve the best results.
It should be noted: Do not use half the battery charge when the battery has been used or suddenly stop using a few months. The standard battery life of one year. Use every two months a year can put a battery, and thus extend battery life with very good results, but the new battery need not refresh again after each time Fangdian. Finally, please note that leakage of the battery will not continue to use, or worth the candle.
Battery should be used originally attached to the charger original, try not to use a full multi-unit charger. General phone with the travel charger, able to do so, as far as possible use of seat-type charger. From the mobile phone directly through the manufacturer to retain charge of this function, it should be a certain degree of technical support. However, damage to the components of such failure on the analysis, generally charging current is too large, more than a cell phone charging circuit of the load caused the main cause of such failure: First, the current power grid voltage instability in many cities in China, in particular the relatively high voltage at night; 2 is due to poor quality batteries, or battery power caused by using too ruthless. On the mobile phone users, the fast charge current best as a temporary or emergency charging method, the use of seat rechargeyour batteries as the main charging. As a way even after the failure, nor will it harm the phone itself.
