What is the quality of the battery, depending on which basic parameters?

Battery capacity: the higher the battery capacity, standby time, the longer the talk time.

Battery resistance: internal resistance is too large, easy to cause "power" or even shut down.

Protection circuit: to ensure that the battery is in normal working condition.


Do you know how to make mobile phone calls longer?

Avoid prolonged calls when the network signal is extremely weak.

Try to choose a strong signal where the call.

Please set the phone mode as much as possible (except for power saving), set the mode, the greater the power consumption.


Why is the cell phone battery with a short standby time?

The battery is not fully charged when used;

The phone itself is more power, the user alone will be all the "wrong" are pushed to the battery, without taking into account other factors;

The direct charge of the phone can not fully charge the battery, will also affect the standby time.


How to buy a battery

According to the requirements of electrical appliances, choose to match the applicable model.

  Pay attention to check the battery production date and shelf life, buy the recent production of the battery (new battery), the new battery performance.

  Pay attention to view the appearance of the battery, you should buy the packaging exquisite, clean appearance, clean, no leakage of the battery signs.

  Pay attention to the battery logo, the battery logo should indicate the name of the manufacturer, battery polarity, battery type, nominal voltage, trademarks, etc .; sales packaging should be Chinese site, production date, the implementation of the standard number.


Buy a new battery, how should charge ah?

Under normal circumstances, the normal stock a month to allow the battery has a natural power-down range of no more than 0.05V. If you exceed this range, you need to analyze the battery: A. Check the battery protection circuit protection parameters are normal, especially its static power consumption should not be greater than 10μA, (usually 3-6μA); by high precision The ammeter (eg FLUKE 187) is connected in series to the "battery-guard board B + / B-" circuit, P + / P-no load, and the current shown is the static self-current consumption of the protection board. B. Analysis of whether the battery is powered down seriously. The batteries (after charging) were discharged to 3.0V and then allowed to stand. 24 hours after the next cabinet to measure the open circuit voltage, 48 hours to measure the open circuit voltage again, for comparison. If the voltage rises, there is a downward trend, then the battery has a power-down phenomenon. Encounter this situation, through the full detection voltage, pick out the lower voltage battery, the rest of the normal use (due to battery inventory time has been longer, there is power outage hidden batteries can be completely singled out). C. Check the batteries in the positive and negative nickel with spot welding process, whether the phenomenon of breakdown. , Too large spot welding current, and incorrect spot welding position, are likely to breakdown within the cell, causing damage, the emergence of low voltage phenomenon.

Aluminum shell batteries have concave surface, will affect the performance of batteries?

Will the battery be fully charged and will it affect the performance of the batteries?

When the call shows 1 grid, after the call shows 2 ~ 3 grid is why?

Finished battery storage for some time, the voltage dropped significantly, what is the reason?
