$begingroup$ 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.
The lead–acid battery is a type of rechargeable battery first invented in 1859 by French physicist Gaston Planté is the first type of rechargeable battery ever created. Compared to modern rechargeable batteries, lead–acid batteries have relatively low energy density spite this, they are able to supply high surge currents.These features, along with their low cost, make them …
Figure 2: Voltage band of a 12V lead acid monoblock from fully discharged to fully charged [1] Hydrometer. The hydrometer offers an alternative to measuring SoC of flooded lead acid batteries. Here is how it works: When the lead acid battery accepts charge, the sulfuric acid gets heavier, causing the specific gravity (SG) to increase.
In that case, the lead-acid battery freezing point is around -76° F. Hence, a fully charged battery is less likely to freeze in cold temperatures. Thus, since water has a freezing point of 32° F, the battery is liable to freeze at a relatively higher temperature than when charged.
When it comes to storing lead acid batteries, selecting the right storage location is crucial for maintaining their integrity and preventing potential damage. Here are some factors to consider when choosing the storage location: Temperature: Lead acid batteries prefer cooler temperatures for storage, ideally between 50°F (10°C) and 80°F (27 ...
A sealed lead-acid battery can be stored for up to 2 years. During that period, it is vital to check the voltage and charge it when the battery drops to 70%. Low charge increases the possibility of sulfation. Storage temperature greatly affects SLA batteries. The best temperature for battery storage is 15°C (59°F).

Your cell should have a voltage equal to 1/6 th of the total battery voltage, assuming you have a typical 6-cell battery. For a 12 volt battery, that means you should get a reading of at least 2 volts from each cell. You''ll also likely be able to visually identify which cells are a problem because they will have different color plates from normal cells.
