voltmeter reading power before i hit button

[Jimilives]

when i put my buzz on the voltmeter BEFORE i hit the button it usualy reads 0.06 to 0.11 and its only the buzz, if i test my other batteries they are at total 0.00 before i hit the button. Is that normal? i am using 2 trustfire icr 123a 880 mah batteries stacked.

That has been confirmed by Mike as 'totally normal' a few times before, and all of them do it. Carry on! ;-)

ohh sweet, thanks so much I tried doing a search but couldnt find anything.

It uses a tiny current to run the electronics inside.

Yep it's normal. The same thing will happen when you test a battery not hooked up to anything.

I use it to gage the power left in the batteries. Mine starts at 13 and when it gets down to 1 or 2 it's time to change.

You must mean 0.13 and down to 0.01 VDC,
I'm seeing how that may work with the LDO VR the Buzz uses, good find SC,
the leakage could be dependent on the charge with no load except the meter ohms/per/volts. your actual readings will depend on the kind/expense of meter but should work with even the 3.99 Harbor F specials, checking myself will post if find problems but don't expect any, THANKS

You are correct. 0.13 to 0.01. My meter is a $12 cheepo from Northern Tool.

knew that SC,
this is great way to check batteries,
now I'm back to maybe drilling a hole in my buzz to bring the + out for a quicker meter attachment, going to use a BIG battery clip on the tube for -.
Still don't know if i need to drink more or less to get steady enough to solder the + wire in the tube, cutting the single chip socket to epoxy is doable while i work on steadying the hands,
