Battery voltage warning

I understand the mistake in my definition. I ment that one peak, is 12.7V.

Normally its not so in my country, plus the RMS description is not really used. All you have is the effective 9V and thats it.

Hi,

"Effective 9V" is "RMS 9V" means 12.7V peak.

What grid voltage do you have in your country. I assume 230V 50Hz.
This is 230V effective = 230 V RMS = 325V peak
