... you guys are right about erring on the side of caution when replacing batteries on critical kit (ie, it's probably best to follow the OEM recommendations). So, let's list which critical bits of kit we're actually talking about (ie, define "critical", in this context), and then perhaps agree that the rules can be relaxed for "non-critical" applications.
OK (here I go talking to myself again):-
DefibrillatorsEmergency Suction Units (
eg, accompanying transport incubators)
Infusion PumpsPortable Patient Monitors (
eg, accompanying transport incubators)
Syringe Drivers
