Flooded lead-acid batteries: These are a type of lead-acid battery that require regular maintenance and can be damaged if overcharged or undercharged. They are often used in industrial applications and other high-demand situations. Gel batteries: These are a type of sealed lead-acid battery that use a gel electrolyte to prevent spills and leaks.

Lead acid battery; voltage under/without load difference

A Lead Acid battery at 11.8 volts without any load is at 0%. You never want to get there. Lead Acid should not be discharged to less than 50% especially a flooded battery if you want more than a hand full of uses before the battery is destroyed. This means that usable capacity of a Lead Acid battery: Is best-case 50% of rated capacity

Lead Acid Battery Voltage Charts

Higher lead acid battery voltages indicate higher states of charge. For instance, 12.6V means a 12V battery is fully charged, while 12.0V means it''s around 50% capacity. Temperature affects voltage, too. Cold temperatures increase the voltage while hot temps decrease it. The charts here assume room temperature.

Battery Glossary – Discharge Voltage – …

The voltage of a battery gradually decreases as it discharges. The rate of this decrease depends on the device it is powering and the battery chemistry. The voltage in sealed lead acid batteries, for example, tends to …

Optimal Voltage Levels for a Fully Charged 12V Battery

While a healthy, fully charged lead acid battery might read between 12.3 Volts and 12.6 Volts at rest depending on charge level (with 12.6 being fully charged), these levels are different for modern lithium batteries!

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."
