Double Power Battery is it true?
Many battery product that claim it capacity with the label "Double Power", "Super High Capacity", etc. but the shape and size of the volume is the same, Is it true? ....
Mostly people compare by daily usage, and the battery can stand more half-day of his ori, or battery brand "H" that can hold 2 days. What if people who use it intensively for browsing or make aphone call for an hour, then could the battery hold till afternoon? .
Devices power consumption are varies one to another, a phone with LCD standby off, different from the condition of the LCD lights up, especially when GPRS usage, greater power is used.
This is pict of measuring the battery capacity, measured by the machine Battery Analyzer, the workings of this machine are as follows:
battery is charged (charge) to full, after full voltage 4.2 V, discharged (discharge) with a constant current until the battery voltage drops where the voltage is if HP is unable to work (about 3V).
Her long discharge will be measured and instantly displayed on-screen machines with units of milliamps Hour (mAh)
The batteries will be tested is the battery Blackberry 9900 Dakota (JM-1) original
For Original Battery
26gr total weight, approximate weight + paper label plate + battery protection circuit is 2 grams, the weight of the battery material 24gr or 0.024 kg
Total Energy = 0.024 kg x 190wh/kg = 4.56 wh
We know the formula below:
Power = Current x Voltage
watts = volts x amperes
Ah wh = 4.56 x 3.6
the capacity (Ah) = 1.267 or 1267 mAh
For other brands:
Alv = 28 gr
as calculated by the above, obtained 1372mAh
HIP = 26 grams, so the calculation of the capacity of 1267mAh
TP = 26 grams, the result is the same 1267mAh
from the calculation, it is impossible to capacity above 1600mAh, battery charger if the material weight only about 24-26gram .
