Changed batteries in all PIRs to Halfrods' Alkaline batteries and it works like a charm.
I find it really odd, people say that Duracells are bigger than other batteries, but I actually measured it with a vernier caliper and they were the same size as halfords'. Also same Duracells were used in all PIRs before.
