Lead-acid battery safety valve leakage
Recently, some peoples have feedback that lead-acid batteries will cause battery leakage and do not know how to solve them. The following summarizes the analysis and solutions of this issue. The safety valve acts as a seal under a pressure. When the specified pressure (opening pressure) is exceeded, the safety valve automatically opens and deflates to ensure battery safety. The main reasons for battery leakage o. a. Too much acid is added, and the battery is in a state of liquid, causing the gas channel for O2 reprocessing to be blocked. When O2 increases, the internal pressure increases. If the opening pressure is exceeded, the sa. This is the case of acid leakage: there is actually a gap inside the two cylindrical terminals of the positive and negative electrodes. There is acid in this gap. Under normal circumstances, the acid will not leaked. When th. A car battery is a device that converts chemical energy into electrical energy. This means that the battery is full of acid.
