Airshield Pro - simple help please

[Martin10]

I have lost/buried the charger for my airshield pro. I have several of chargers that are the same spec (voltage/power etc) but I can't find anywhere the polarity (ie is the centre pos/neg?). It is about 3 years old (and has held its charge so well I didn't miss the charger!).

Just noticed no one had answered this so have just been out to the workshop

The centre is positive
