How bad is it to undervoltage a 12-volt lead-acid battery?
Summarizing, the main points are these two: 1) Once a 12V LA battery is down to 10-11V, the voltage will plummet rapidly. No real point in pushing it farther (and risking point 2), given that you only get a few % extra current out of it. 2) If a multi-cell battery is discharged too deeply you risk "polarity reversal" in the weakest cell.

6 FAQs about [Lead-acid battery undervoltage protection voltage]
How do you protect a lead-acid battery?
The circuit of Figure 1 protects a lead-acid battery by disconnecting its load in the presence of excessive current (more than 5A), or a low terminal voltage indicating excessive discharge (< 10.5V). The battery and load are connected by a 0.025Ω current-sense resistor (R1) and p-channel power MOSFET (T1).
What voltage should a 12V lead acid battery be charged?
The ideal charging voltage for a 12V lead acid battery is between 13.8V and 14.5V. Charging the battery at a voltage higher than this range can cause the battery to overheat and reduce its lifespan. How does temperature affect lead acid battery voltage levels? Temperature affects lead acid battery voltage levels.
When is a lead acid battery fully charged?
A lead acid battery is considered fully charged when its voltage level reaches 12.7V for a 12V battery. However, this voltage level may vary depending on the battery’s manufacturer, type, and temperature. What are the voltage indicators for different charge levels in a lead acid battery?
What is a lead acid battery voltage chart?
A lead acid battery voltage chart is crucial for monitoring the state of charge (SOC) and overall health of the battery. The chart displays the relationship between the battery’s voltage and its SOC, allowing users to determine the remaining capacity and when to recharge.
Does temperature affect the voltage level of a lead acid battery?
Temperature affects lead acid battery voltage levels. The voltage level of a lead acid battery increases as the temperature decreases and vice versa. Therefore, you need to consider the temperature when measuring the voltage level of a lead acid battery. At what voltage level is a lead acid battery considered fully charged?
What is the difference between sealed and flooded lead acid batteries?
The voltage requirements for sealed and flooded lead acid batteries are different. Sealed lead acid batteries have a slightly higher charging voltage requirement than flooded lead acid batteries. This is because sealed lead acid batteries have a lower internal resistance. They need a higher charging voltage to reach their full capacity.
