These will probably be gel batteries, so 30 volts would be too much.  Most 
AGMs should also not be charged that high.  

For most gel batteries (absent instructions otherwise from the mfg.) 
charge 
to about 14.1 - 14.3 volts each, measured while on charge, with a constant 
current or voltage-regulated charger.  This will also hold for most 
low-end 
AGM batteries.  

Hawkers are an exception.  With those 14.8 volts per module is OK.

If the above voltage is held, the current will eventually drop to about 
1-2% 
of the amp-hour rating (expressed in amps).  That means they're fully 
charged.

    Their talk was the talk of sordid buccaneers: it was 
    reckless without hardihood, greedy without audacity, 
    and cruel without courage; there was not an atom of 
    foresight ... in the whole batch of them, and they did 
    not seem aware these things are wanted for the work of 
    the world.
