Learn MoreTo charge a sealed lead acid battery, a DC voltage between 2.30 volts per cell (float) and 2.45 volts per cell (fast) is applied to the terminals of the battery. Depending on the state of charge (SoC), the cell may temporarily be lower after discharge than the applied voltage. After some time, however, it should level off.
Learn MoreLead Acid Aircraft Battery Maintenance & Charging March 2021. All aircraft batteries, regardless of whether they''re a ni-cad, lead acid or lithium, will require maintenance at some point and time. That maintenance may come in the form of an Open Circuit voltage (OCV) check, periodic check, capacity test or various other inspection criteria.
