new battery voltage

[richardtan]

Hi Experts, :wavey:

I heard that the older a battery gets the higher the voltage it can produce?
It is true?

For a new 12v car battery, what voltage should indicate a healthy battery?
12.5V ok?

If the engine is revved, the voltage goes to 13.6v. Is this normal?

How long to charge a new MF battery? or no need? Is it plug and play?

sincerely
Richard

It is true? Don't understand the question

12.5V ok? Yup... its normal

If the engine is revved, the voltage goes to 13.6v. Is this normal? if no accessories running such as ICE, headlamps, air-con, radiator fan etc ... you can get as high as 14++. if volt drop below 12v then you should send to workshop to check whether battery or alternator kong

How long to charge a new MF battery? or no need? Is it plug and play? You mean tried to sent dead MF battery to workshop to charge? not recommended since we don't know how many water inside it.... MF battery sizes follow conventional battery so its pnp
