No
Not all the batteries are identical; see the link below.
No, only rechargeable batteries can be recharged.
Series: Double the voltage of one of the batteries if they are the exact same size. Amps stay the same as one of the batteries. Parellel: Double the amps and voltage stays the same as one battery.
No
You have + and - on batteries, the polarities have to be in the same direction or the current won't flow.
-- If all 8 batteries have the same rated voltage as the inverter input, then they must be configured in parallel. -- If the batteries are not rated the same voltage as the inverter input, then some combination of series and parallel has to be designed. The specific configuration depends on the details of the batteries you have.
That would depend heavily on whether you're talking about wristwatch 'button' batteries, automotive storage batteries, or telephone central office UPS batteries.
Rechargeable batteries have been used for a long term in our daily life in many devices like our vehicles. Such types of batteries do not function in the same way that solar-powered batteries do.
