0.05C is the so-called C-rate, used to measure charge and discharge current. A discharge of 1C draws a current equal to the rated capacity. For example, a battery rated at 1000mAh provides 1000mA for one hour if discharged at 1C rate. The same battery discharged at 0.5C provides 500mA for two hours.

ANY battery does not just throw amperage or current; it will first discharge as much current as physically possible based on its chemistry and chemical reaction, and then what limits this discharged current is the resistance of the circuit it is connected to.
There are several methods and devices that can be used to test a battery''s capacity. The easiest and most common way to test a battery''s capacity is to measure its voltage and current under load. Once the battery is fully charged first, a load is placed on the battery and then the voltage and current of the battery is measured.
The battery discharge test is perhaps one of the most reliable tests you can perform on a battery or a battery bank. It provides a comprehensive insight into the health status of the cells. In this post, we will analyze this test …
Discharge time is basically the Ah or mAh rating divided by the current. So for a 2200mAh battery with a load that draws 300mA you have: $frac{2.2}{0.3} = 7.3 hours$ * The charge time depends on the battery chemistry and the charge current. For NiMh, for example, this would typically be 10% of the Ah rating for 10 hours.
Figure 1 - Normal battery. The acid is equally distributed from the top to the bottom of the battery, providing good overall performance. Figure 2 - Stratified battery. The acid concentration is light on top and heavy on the …
A test current of 19A is required for a 5-hr constant-current discharge test to an end cell voltage of 1.75Vpc. Once the test current is determined, the next step is to determine the capability of the test equipment.
C-rate of the battery. C-rate is used to describe how fast a battery charges and discharges. For example, a 1C battery needs one hour at 100 A to load 100 Ah. A 2C battery would need just half an hour to load 100 Ah, while a 0.5C battery requires two hours. Discharge current. This is the current I used for either charging or discharging your ...
Discharging can take place at up to 220 A, and if higher current is needed, two or more TORKEL units or extra load units (TXL) can be linked together. The TORKEL900 series has three models available: 910, 930, and 950, depending …
