Battery Testing

Hello,

I manage a fleet of Mercedes Benz C250 (2011-2014). I am currently testing all of the batteries based on the CA and CCA of the vehicles. However I am new to this and a bit confused on what the batteries are rated for. On them they read [12v/800A/80Ah (En/Sae/Gs)]. I know what most of these acronyms stand for but I am unable to determine the CA or CCA from the given information. What am I missing/overlooking!?

Please help, cite responses if possible as this is work related.


Thanks!!

Here is the problem I am concerned
