When many consumers purchase mobile phones, they are often promised by businessmen for a month’s standby.But when they use the mobile phone, its battery can only support half of a month, even after several days spent no electricity.
To this end, the relevant departments remind consumers, mobile phone battery is a special commodity, they need to go through strict production and various strength tests, choosing a improper batery to use may cause an explosion, the election must not be lightly to avoid loss. To achieve the “long standby,” you’d batter to use original battery, and pay attention to using power-saving mode. Many batteries are priced dozens of yuan, they couldn’t achieve the businessmen’s promise.
Battery capacity generally is basis on AH (amp hours), the other is CELL (flat plate) a few watts (W). (W / CELL) . 1.AH (ampere hours), is defined as the standard of 20 hours. For example, 7AH battery is the continuous discharge current 0.35A, time continuous 20 hours. 2.W (W (power consumption) / CELL (flat plate)) basis, defined as the standard of 15 minutes. For example, 1221W battery 12V (6 CELL), each CELL 21W power supply can be powered for 15 minutes. 3. Charging time to 10 hours for the standard charge current for the battery capacity of 1 / 10, fast charge will reduce battery life.
Battery capacity refers to the size of the battery storage capacity. The unit of Battery capacity is “mAh”. If the battery’s rated capacity is 1300mAh, and if as 0.1C (C is battery capacity) mean 130mA of the unit to discharge the battery, then the battery can last 10 hours (1300mAh/130mA = 10h); If the discharge current is 1300mA, then it can be used for 1 hour. This analysis is under the ideal state, digital equipment, the actual work of the current can not always constant at a value (in digital cameras, for example, because of the work of current LCD display, flash and other components which occurs on or off the larger change), so the battery can power a device is only about the value of time, and this value can only be estimated through practical experience.
