The low voltage cut-off (LVC) is a critical parameter for any 12V lead acid battery. It defines the lowest voltage point at which the battery should be allowed to discharge before the load is disconnected. Typically, the LVC is set at
The Low Battery voltage cutoff in the lead Acid is kept at 10.5 Volts to keep it safe.
One of the most common reasons a lead acid battery shows 0V is sulfation. This happens because, inside a lead acid battery, there are lead plates that are coated with lead dioxide and are separated by a porous separator. When the battery is in use, the lead dioxide reacts with sulfuric acid and produces lead sulfate and hydrogen ions.
To identify the bad cells in a lead acid battery, follow these steps: Charge the battery for at least 12 hours and then allow it to rest for 10 minutes. Open the battery caps and fill each compartment with water to within optimum levels. Measure the terminal voltage of the battery.
To recover a lead acid battery, charge it for around 10 to 12 hours. Then, measure the terminal of the battery. After that, check the voltage of each cell and identify any cells with a voltage lower than 2 volts.
A lead acid battery should never be below 11.80 volt at rest. ↩ 'bad' battery protection solutions will just start to oscillate as the battery voltage recovers (above the cut-off threshold) when the load is removed. I bought a cheap 20 Euro unit and it was effectively useless because of this problem. ↩
The resting voltage of a 12V lead acid battery refers to the voltage measured when the battery is not under load (i.e., not connected to any circuits or devices). After a period of rest, a fully charged battery should have a resting voltage around 12.6 to 12.8 volts.

What you can do is set the inverter to switch off on battery voltage and SOC. Set your system to shut off around 10% SOC min to allow for cell imbalances at lower soc. The victron 12v charger should wake up the other battery.
Choosing a low voltage limit shelters the battery, but this produces poor performance and causes a buildup of sulfation on the negative plate. A high voltage limit improves performance but forms grid corrosion on the positive plate. While sulfation can be reversed if serviced in time, corrosion is permanent. (See BU-403: Charging Lead Acid) Lead acid does not lend itself to fast charging …
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 …
What is the difference between a low-voltage battery cutoff for a lead acid battery versus a lithium battery? The Low Battery voltage cutoff in the lead Acid is kept at 10.5 Volts to keep it safe.
Discharging beyond this point can lead to a condition known as deep discharge, which is particularly harmful to most battery chemistries, including AGM and flooded lead-acid batteries. For lithium-ion batteries like LiFePO4, although they are more resilient to deep discharges, maintaining a cut-off voltage at 44V helps in preserving the overall battery health …
Capacity: Measured in amp-hours (Ah), capacity indicates how much energy a battery can store.For example, a 100Ah battery can deliver 5A for 20 hours. Voltage: Most lead acid batteries operate at 12V, commonly used in solar systems.Higher voltage systems often combine multiple batteries in series. Cycle Life: This represents the number of complete …

And then would the momentary sags of 15-30 seconds where the battery voltage would drop down below 24v when an inductive load kicks in ... would that be seriously damaging the batteries. And also what voltage would be a good place to let the inverter turn off and kick the entire load to the AC Line in. I can set that to just about voltage I ...

5 Lead Acid Batteries. 5.1 Introduction. Lead acid batteries are the most commonly used type of battery in photovoltaic systems. Although lead acid batteries have a low energy density, only moderate efficiency and high maintenance requirements, they also have a long lifetime and low costs compared to other battery types.
A lead–acid battery cannot remain at the peak voltage for more than 48 h or it will sustain damage. The voltage must be lowered to typically between 2.25 and 2.27 V. A common way to keep lead–acid battery charged is to apply a so-called float charge to 2.15 V. This stage of charging is also called "absorption," "taper charging," or ...

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.
