Keith McMillan battery tester.

Me likey. I've never seen a product like this before (I guess I've never been that concerned about effects pedals until I got one at Christmas either). Every gear box should have one.

On reading the topic title my first reaction was 'oh, its a bloke who goes around licking duracells and telling you how much charge is left in to the nearest volt or something'

That looks good - great that you cn test them without getting the batteries out. That would be especially good f you just know one of your pedals batteries is wonky but can't tell which one. A fast solution.

I have several of these at home and in my gadget boxes

I was going to say. You can get a cheapo multimeter out of B&Q or Maplins for a fiver.

As long as you are aware that an off-load battery should show well over it's nominal voltage. That is a 9V battery actually reading 9V is flat

If you stick a meter over a battery that isn't connected to anything then it isn't doing any "work". The voltage you read then floats up well above the voltage printed on the side. It depends on the type of battery but around 10% will do as a guide. So if you test a 9V battery and it reads 9.0V then it's as flat as a pancake. It should read more like 9.7 or so.

You have to be careful with digital meters as they have an incredibly high input resistance. They don't exist in the circuit you connect them to effectively. This is usually what you want but you do have to bear it in mind.
