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
Hydrometer
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.)
sulphuric acid
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.
There are a few variables to take into account here. The discharged state of the battery and the current produced by the battery charger on the slow charge position are two of the most important. The amp/hour size of the battery is another governing factor.
This could indicate a low state of charge for the battery.
a hydrometer checks the state of battery charge using specific gravity.
Batteries are storing charge or free electrons. The state is by nature a fixed voltage rather than a varying voltage. You can convert the battery charge to AC by using what is called an inverter.
