Minimum battery voltage

[XwindXTO]

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

diba * 9v tulak na ito diba ^_^

Nastart ko pa at 9V. Pero may dasal na kasama. Hahahaha!

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

Pero usually 8.5v pataas kaya pa.

i see, sakin pala naalala ko pag ON ko ng auto eh totally wala na umilaw sa dash. pero nakuha pa sa tulak ^_^

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

Depends sa age ng battery. If too old, baka hindi na maghold ng charge. You will charge today, pero drained ulit the next day. If you have battery charger, use it. No harm in trying.

So how do you measure the remaining amperes of your battery? Para alam mo kung magstart pa engine?

use the ampere meter

[red_one]

use the ampere meter

Ampere meter is not easy to use on car battery. Whereas a voltmeter, you just connect in parallel sa terminals. Basta 12V and above, I am good to go. One click start. Never pa ko nagmeasure ng amperes ng battery.

maybe your multi tester has only up to mA (milliamp) range. Mayron sa T alonzo high ampere range.

I have a 400Amps AC-DC digital clamp meter but I have not used it for car battery yet.

Ito lang ginagamit ko. In-car voltmeter.

Engine Off - 12.6V (Battery OK - Fully Charged)



Engine On - 14.5V (Alternator OK - Battery Charging)

iba yung saken. mine is digital handheld clamp meter multimeter with probes. if mahanap ko sa bodega i post ko.

[kai s.]

^ I use the same voltmeter that *red_one posted. Seems accurate naman, same reading with the handheld clamp type meter used by the casa when I had my car serviced last weekend.

I use a similar one pero I bought one na walang temperature. Kahit cheap chinese gadget sya, accurate sya.
