Expectations vs. Reality: Making Sense of Battery Voltage & Percentages

Looking back at the State of Charge chart above, the battery only dips below 12V below 9% capacity. So, when it crashes, it crashes hard -- as Sarah and Mark discovered. But a Lead Acid battery dips below 12V at just under 50% capacity. So a 12V motor, like the fan, will simply slow down if it''s getting less than its "nominal voltage."

Deep Cycle Battery Voltage Chart: A Comprehensive Guide

For example, a 12V lead-acid deep cycle battery at 100% capacity will have a voltage of around 12.7V, while a battery at 50% capacity will have a voltage of around 12.2V. By measuring the voltage of the battery and comparing it to the chart, you can estimate the remaining capacity of the battery.

Lead Acid Deep Cycle Battery Voltage Chart

48V Lead-Acid Battery Voltage Chart. The 48V battery voltage chart for a gel-sealed lead-acid battery found below varies from 52.00V at 100% charge to 42.00V at 0% charge.. A full battery has a 10.00V absolute voltage difference from an empty battery. This chart indicates that this 48V battery still has 20% to 30% charge left …

Why does the voltage of a lead-acid battery drop with load?

It''s a typical 12 volt lead-acid battery discharge characteristic and it shows the initial drop from about 13 volts to around 12 volts occuring in the first minute of a load being applied. Thereafter, the discharge rate doesn''t unduly affect the output voltage level until the battery gets quite depleted of stored energy.

Lead-Acid Battery Basics

Here is the response from the author: "While it is generally recommended to avoid deep discharges beyond 50% for lead-acid batteries to maximize their lifespan, some specific types or applications of lead-acid batteries, such as …

How To Charge A Lead Acid Battery

To 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.
