Minimum battery voltage

What would be the minimum battery voltage needed to start the engine?

I have a 02 Crosswind XTO

9V. Pero hirap na sya. I replaced battery after.
Sa 10V, its a few weeks left. Assuming usual first start... Not multiple straight starts

Depende sa starter motor, cabling at compression ratio at number of cylinders...

Pero usually 8.5v pataas kaya pa.

pero sa naranasan ko minsan e 11.5 volts hindi na kaya...different car brand though. after chinarge ng 8 hrs ayun ok uli. sabagay beyond the service life na yung battery kaya pinalitan din few days after charging.

9V while cranking is okay. Normal na bumaba ang voltage during cranking.

9V at rest (not cranking) is already dead battery. 10.5V is 0% charged.

Kaya pa ba madala sa digital charger ang pag charge ng mga naka 9v na batt para bumalik sa optimum or satisfactory condition?

to be or not to be, that always confuses me!

It's not voltage that determines whether you can start the car, but it's the starter's ability to deliver amperage. A volt meter will only give you a rough idea of the state of charge assuming that the battery is known to be in good condition. An average car batt produces roughly 400 to 500A to start the car. Assume the car batt is 9V while cracking but the ampere is only 70 so di pa rin mag-start ito
