On the basis that what you call a "drop tester" is what I know as a "Heavy discharge rate meter" and the test involves bridging the poles and sparks then the answer is emphatically NO A starter battery is designed to have a high rate of discharge. It has to be able to twirl over an engine. The inside is built differently from a "Leisure" battery which is desinged to release small amperages over a very long time. Using a "Heavy discharge rate meter" on a leisure battery would lead to rapid heating of delicate plates and at the worst possible scenario an explosion scattering lead acid over an area much bigger than a typical engine room or garage. Your work practice will be for starter batteries, Darren am I right?

Tony, while I agree with your could be's, the OP is not a technical person and you are possibly going scare her to death. Its a pound to a pinch of dirt that that the PRV needs replacing at very little cost as others have said. This is, I am sure you will agree, particularly the case when a PRV has not been regularly "tweaked" to clear any debris build up. Cheers A
