What is the best battery to use a digital cell phone? (B)
In Figure 3, we study the relationship between energy density (Capacity) and internal resistance of Li-Ion, NiMH and NiCd battery. To simplify the comparison, all battery packs are 3.6 volts.
As to the question of longevity, also includes the "best time of the cycle. It is noted that periodic cycles are necessary to discharge the planned cycle NiMH and NiCd. Successive rounds contributes very little to enhance the performance of Li-ion battery.
Even if overall energy needs of mobile digital is less than equivalent analog phone, digital phone battery must be capable of providing high current pulses that are often several times their own charge rate. Now the rate of battery charge as stated in the loading rate C.
A discharge rate of C a battery is 500 mAh, is 500 mA. Comparatively, a 2 C discharge the same battery is 1000 mA. A GSN phone powered by a battery which draws 500 mA 1.5 A pulse, for example, charge the battery with a huge dump 3 C.
A load dump rate is 3 C is suitable for a battery with a very low reading MO. However, the old and Li-ion battery Nimh Batteries are a problem because these batteries MO reading increases with age and number of cycles.
* Wiring internal contacts and protection circuits are taken into account. Readings vary depending on the elements, charge status and the number of elements connected in series.
** The download is highest during the first 24 hours and decreases thereafter. Self-discharge increases with age Lenovo ThinkPad Series r61i and high temperatures.
*** The length of the cycles of life is based on depth of discharge. A shallow that have occurred over a deep discharge cycles.
**** The life cycles based on use and maintenance procedures. If we neglect to apply periodic full discharge cycles, the cycle can be reduced by a factor of three.

The performance can be improved by using a larger battery, also called battery pack extended. This package of battery life is a little larger and a bit heavier, but offers a typical loading rate of about 1000 mAh or approximately twice a thin battery. C in terms of a rate of loading, unloading three C is reduced to 1.5C when using a battery of 1000 mAh instead of 500 mAh. The disadvantage of a large NiMH or NiCd is an increase in memory if, due to its higher capacity, the battery has not often allowed to discharge completely.
Some of the new phones generation are equipped with a core DC-DC converter, which reduces the demand for battery power. With this chip, typically 1.5 A pulse can be reduced half to stretch the peak current of the battery for a longer period. However, the disadvantage is the loss of current 10-12%. The increased capacity of the battery is also tested, but the current strong eruption occurs when the device is switched on, remains a problem. The size of cell phone can also be a problem when adding a higher capacity battery.
