For a typical lead-acid battery, the float charging current on a fully charged battery should be approximately 1 milliamp (mA) per Ah at 77ºF (25ºC). Any current that is greater than 3 mA per Ah should be investigated. At a recent International Battery Conference (BATTCON®), a panel of experts, when asked what they considered were the three most important things to monitor on

When charging a lead-acid battery, there are three stages: bulk, absorption, and float. During the bulk stage, the battery is charged at a high current rate until it reaches 80% to 90% of its capacity. The absorption stage then follows, where the battery is charged at a lower current rate until it reaches 100% capacity. Finally, during the float stage, the battery is
