Standard discharge current is related with nominal/rated battery capacity (for example 2500mAh), and cycle count. If the battery is discharged with a higher current, the real available capacity will be smaller (it may be much smaller). Discharging the battery with a lower current will extend the real available capacity a little bit.
The test is conducted according to the ISO 12405-2 standard. First, discharge the battery at 1C for 18 seconds, then discharge at 0.75C for another 102 seconds and record the V1 and I1 values.

Internal defects and aging can cause batteries to not fully charge, not fully discharge, or overheat under load. This is wasted energy for the user. Therefore, it''s important for manufacturers and battery researchers to measure values like DC internal resistance (DCIR) to identify low-quality batteries or to help study degradation behaviors.

DC power system. For important telecom devices, the performance of battery groups is crucial. Because when a power outage happens, battery groups are the only power supply for keeping DC power system operating uninterruptedly. Obviously, the periodical discharge test is essential for checking the ability of batteries in use. Max Discharge
Capacity discharge testing is the only true means for measuring battery capacity, which must be known to estimate runtime for a given load. A resistive DC load bank provides the best practical means for properly conducting capacity tests. Periodic capacity testing enables evaluation of battery service life and can help avoid catastrophic failures.
The discharge test can be conducted even in case a battery remains connected to the load – by measuring and taking into account the load current during the process. The BLU-A series devices provide the discharge current of up to 240 A and are applicable to up to 500 V battery voltages.
Due to this degradation, periodical Battery Capacity (Discharge) testing becomes necessary to ensure the optimum power backup from Battery Banks for the desired duration. Let's dive into battery discharge testing—the backbone of effective battery care—guided by the recommendations from three key IEEE standards: IEEE 450, IEEE 1188, and IEEE 1106.
The discharge test was performed on a battery bank with 56 cells and 112 V (2 Volts/cell) installed in Jan 2003. Its published ratings are shown in Table 2. The average cell temperature measured was 20 0C. A performance test was conducted at a constant discharge current of 95.1 A for a 3 hour time duration using the time adjusted method.
The value of DCIR is not fixed, and varies depending on multiple factors, such as battery materials, electrolyte concentration, temperature, and depth of discharge. The variation of DCIR has a great influence on battery discharge performance, especially for high power batteries.
Only one pause is allowed for the duration of the test and the pause time should not be counted in the total discharge time2. Once the test is completed, determine the battery capacity. The test equipment can then be disconnected. While performing the discharge test, one should be prepared to bypass weak cells approaching polarity reversal.
