How to Tell If a Deep Cycle Battery Is Bad
Each cell in a battery (just after a full charge) is 2.2 volts. After resting for 12 to 24 hours, the voltage drops to 2.1 volts per cell. So, a charged but rested 12-volt battery will actually be around 12.6 volts after charge. And a 6-volt battery will read 6.4 volts. It''s important to understand this, so you don''t get a false reading.
What Voltage should a Marine Battery Read When Fully Charged?
A 12-volt marine battery should read 14.4 volts when fully charged, while a 24-volt marine battery should read 28.7 volts when fully charged. With that said, there are other important facts about marine batteries you should also keep in mind. This includes the difference between the voltage of a full charge battery and float voltage.
How To Maintain Batteries
Specific Gravity: Full charge SG will run from about 1.260 in an auto battery to about 1.275 in a golf cart. High SG (more acid) allows more juice (current) to be drawn--but only up to a point; then the battery deteriorates--fast. Golf cart plates are made to handle this, RV/Marine somewhat, automotive not at all.

19.1 Electric Potential Energy: Potential Difference
Voltage is not the same as energy. Voltage is the energy per unit charge. Thus a motorcycle battery and a car battery can both have the same voltage (more precisely, the same potential difference between battery terminals), yet one stores much more energy than the other since ΔPE = q Δ V ΔPE = q Δ V. The car battery can move more charge ...

Is a battery healthy if drops under 10 volts with load?
A battery with 1 dead cell therefore has a voltage of around 10.5 volts, 2 dead cells = 9.4 volts, etc. But usually once one cell goes bad the battery is replaced before others die as well. A bad battery can show a false voltage when it has surface charge, this occurs for a length of time after a battery has been charging.

How does that work? Here is where the gray area exists. When fully charged, each 3.6-volt cell can hold up to 4 volts. So, both 20V and 18V batteries can display 20V when fully charged, while a 12-volt battery with only three cells can read 12 volts. Amp Hours Matter, Too. Voltage is only half the story: amp-hours matter too.
Pololu
A typical alkaline or NiMH battery in the standard "AA" size has about 2000 to 3000 mAh (or 2 to 3 Ah). With a cell voltage of 1.2 V to 1.5V, this corresponds to 2 to 4 Wh per cell.
