Does anyone test Lifepak CR Plus defibrillators? This model is not like the 500 or 1000 whereby standard output tests can be performed because as soon as you discharge one of these, the battery replacement symbol appears. This will remain until the battery is replaced and it doesn't matter how recent the battery was changed.

This is mentioned in the manuals as it states that these batteries last 2-years as long as they are not used for discharge. The only way round this is to keep a used battery for the sake of the PIP checks. Otherwise, perhaps a user type check for the OK symbol and battery/electrode expiry date check? These defibs are apparently used in commercial situations eg airports, hotels etc.,but rarely in hospitals. Any ideas?
