Default P300 misfire under load

Car is juddering at 2500 rpm - when accelerating - Reader shows p300 random cylinder misfire - i know this can be due to many reasons - first one being failed ignition coil/HT leads / spark plugs/gapping etc. Anyway whilst having a look at these things i had a look at the battery which i have always had low resting voltage readings 12.2-3 (under RAC warranty and they insist its OK) and both terminals are covered in quite extensive whitish/green deposits - never seen this before on any of my batteries. So could a defective battery produce misfires?
