Installed new battery "Physio Control 11141-00156" got half way through the PIP as per service manual, from having a full battery at the onset of the PIP it was reduced to 1/4 capacity,
only having carried out a discharge at 360J & 100J to control the discharge calibration.
Question.. anyone else has had this problem?? because this is not the first it's happened to me,maybe an inherent software problem with the PIP which over stresses the battery?
In the user manual the battery is as 12V 6.2Ah,the one supplied 12V 4.5Ah could this be some sort of an equivilent grey import,which is strange as when searching the reference number results in hundreds of apparent hits for OEM batteries
