AI Customer ServiceThe voltage of the battery depends on the chemistry of the cell it is based on. For ex, a Lithium-Polymer cell has a nominal voltage of 3.7V and that of a lead-acid cell is 2V.
AI Customer ServiceThe amount of voltage drop will depend on how much current the battery is supplying. A 12 volts battery should read around 11 volts when under load. Keep in mind that this is just a general guideline and may not be accurate for all situations. If you are unsure of what the voltage should be, it is best to consult with a professional.
Additionally, as a battery discharges, its internal resistance increases, which also contributes to a voltage drop. Finally, when a battery is heavily loaded, the active materials within the battery start to dissolve, which also reduces its performance. All of these factors work together to cause a voltage drop under load.
When a battery is under load, the voltage reading will be lower than when it is not. This is because the battery is providing power to something else and is not just sitting idle. The amount of voltage drop will depend on how much current the battery is supplying. A 12 volts battery should read around 11 volts when under load.
A good battery will sit around 12.6 to 12.8 volts when fully charged. When a good battery is put through a load test equal to its rated CCA (cold cranking amps) its voltage will drop to around 9.6 to 10.5 volts depending on the ambient temperature. It will then shoot back up to ~12.6 volts once the load is removed.
It can read a full voltage of 12.6 even though it has a bad cell. However, when a battery with a bad cell is put under load, it will immediately fall well below its real voltage of 10.5 volts. Once the load is removed, it will only bounce back up to its maximum 10.5 volts. So when is 10 volts enough?
(Why Does) As a battery discharges, the voltage it produces decreases. However, the amount of voltage lost during discharge depends on the type of battery and how it is used. For example, lead-acid batteries typically lose about 2% of their voltage per cell per hour when discharged at a constant rate. As a battery discharges, its voltage drops.
