Lead-Acid Battery Safety: The Ultimate Guide
The electrolyte''s chemical reaction between the lead plates produces hydrogen and oxygen gases when charging a lead-acid battery. In a vented lead-acid battery, these gases escape the battery case and relieve excessive pressure. But when there''s no vent, these gasses build up and concentrate in the battery case.
Battery 101: 3 Useful Facts On Lead Acid Batteries
Whereas a lead acid battery being stored at 65℉ will only discharge at a rate of approximately 3% per month. Length of Storage: The amount of time a battery spends in storage will also lead to self-discharge. A lead acid battery left in storage at moderate temperatures has an estimated self-discharge rate of 5% per month.
Battery Charging and Discharging Parameters
A common way to measure the BSOC is to measure the voltage of the battery and compare this to the voltage of a fully charged battery. However, as the battery voltage depends on temperature as well as the state of charge of the battery, this measurement provides only a rough idea of battery state of charge. Depth of Discharge
