If there is a dead or weak cell, normal charging voltage can''t be achieved on a battery with a bad cell. The alternator will overcharge the remaining cells and boil the electrolyte in the other cells. At the other extreme, a battery that is sulfated due to being undercharged or not seeing constant use will maintain normal charging voltages.

The battery cycle life for a rechargeable battery is defined as the number of charge/recharge cycles a secondary battery can perform before its capacity falls to 80% of what it originally was. This is typically between 500 and 1200 cycles. The battery shelf life is the time a battery can be stored inactive before its capacity falls to 80%.
Technically the minimum amount of voltage for charging will be anything above the current state of charge. But that''s probably not the answer you''re looking for, from Lithium-ion battery on Wikipedia:. Lithium-ion is charged at approximately 4.2 ± 0.05 V/cell except for "military long life" that uses 3.92 V to extend battery life.
For a typical 6f22-form factor battery it is something 2-20 ohm for a new battery at room temperature. It gets higher as the battery gets discharged, rises with discharge current and gets a bit lower for moderately elevated temperature (say, ~50C). The initial short-circuit current for such a battery is ~1 Ampere.
At what voltage is a 12v gel battery fully charged? If a gel battery reaches an open circuit voltage of 12.85 volts, then the battery is completely charged. However, you apply a higher voltage to charge the battery. The charging voltage of a GEL battery should be from 14.1 to 14.4Volts depending on the manufacturer. Use 14.1 to …
What is the Minimum Voltage Needed to Start a Car? When your battery''s voltage drops even a small amount, it makes a big difference in its overall performance. The chart above shows what the voltage should be for different states of charge. As you can see, a voltage of 12.1V means your battery is operating at only 50% of its total charge.
Combining the previous info about battery charge and usage levels, modern (current-generation) laptops today with a 3,000 to 6,000 mAh-rated Li-ion battery can typically last on average about 5 to 6 hours with a mix of light, moderate, and heavy use. Although, depending on how efficient the usage is, you can easily squeeze or slash …

If your last trip was a short drive, the alternator might not have had enough time …
Fact: The VOC is an essential parameter in battery specifications and gives users an idea about the maximum potential of the battery. Voltage Drop with Load. When a load, such as a motor or a light bulb, is connected to a battery, it draws current. This current flow, combined with the battery''s internal resistance, causes a voltage drop.
