GMDSS battery and aerial checks

[pignutpilot]

What are the requirements for GMDSS battery and aerial checks? Such as how often you check the S.G. of the acid etc...

There doesn't seem to be a whole lot of in depth info that I can find that tells you specifically what you are meant to do. Many officers I speak to about this, each have slightly different views as what is required. So what is the definitive answer, it must be written somewhere?

monthly, my last ship had maintenance free batteries and an on load battery tester which made life much easier.
