The state of charge (SoC) of a nickel-cadmium (NiCd) battery is typically determined by measuring its open-circuit voltage (OCV) after a resting period, as the voltage correlates with the charge level. Additionally, a discharge curve can be used, where the voltage is monitored during discharge to estimate the remaining capacity. Another method involves using a specific gravity meter to measure the electrolyte density, but this is less common. Overall, OCV measurements are the most practical approach for determining SoC in NiCd batteries.
No, the charge in the battery is a change in state of the battery contents, not an addition to the battery.
Battery stave means nothing at all. Battery state on the other hand means the state of charge of the battery. Is it fully charged or 75%- 50%- 25% charged, etc.
You can't update a psp without a working battery. It'll state that the battery is low and you need to charge it.
It depends on the state of charge. A fully charged lead-acid 12V battery will measure around 13.6V, the same battery at the end of useful charge will be approximately 10.5V

No.AnswerPresumably, you mean 'specific gravity' or, as it is known these days, 'relative density'? If so, the relative density of a lead-acid cell or battery is, indeed, a guide to that battery's state of charge -that's why we use a hydrometer to check the condition of a lead-acid battery. However, it would be wrong to say that the relative density of a lead-acid battery 'effects' the voltage -it merely is a guide to the state of charge. (Actually, it's the state of a battery's charge that affects its relative density.)
Two common methods for checking a battery's state of charge are using a multimeter and a hydrometer. A multimeter measures the voltage of the battery; a higher voltage typically indicates a fuller charge. A hydrometer, on the other hand, assesses the specific gravity of the electrolyte in lead-acid batteries, providing insight into the charge level based on the density of the liquid. Both methods can help determine the battery's health and charge status.

The battery indicator lamp illuminating usually means that the battery is not receiving or accepting a charge from the alternator and is being drained past an unsatisfactory state of charge.
To check the specific gravity of a battery, you will need a hydrometer. Remove the battery caps and draw some electrolyte into the hydrometer. Compare the reading with a chart to determine the specific gravity, which will indicate the state of charge of the battery.
This could indicate a low state of charge for the battery.
a hydrometer checks the state of battery charge using specific gravity.
