If a battery used to supply a DC voltage source to a protection or mechanical system does not work properly, the battery cannot supply DC to auxiliary equipment during an emergency. For that we need a discharging test to determine the capacity of the battery used so that it can know the ability of the battery to supply DC loads continuously at the substation. This research was conducted at the Bandung Cigereleng Substation with data taken from the emptying test results in 2017 and 2019. The results showed that in 2017, the battery capacity was 299.86 Ah with an efficiency of 94%. In 2019, the battery capacity will decrease to 253.92 Ah with an efficiency of 79.5%. That is, within a period of ± 2 years there has been a decrease in battery capacity by 45.94 Ah and efficiency by 14.5%.} }
