it's what 1500 hours of life in a 9V these days? Trying to remember a stat I read very briefly on a forum last week haha.

But yeah 9V in guitars has been a thing since the 80s at least, just don't leave the guitar plugged in :)

Battery life is dependent on battery type and load.

A typical 9V alkaline has about 500mAH capacity, that will supply 500mA (0.5A) of current for 1 hour, or 50mA (0.05A) for 10 hours.

Lithium based 9V batteries have about twice the capacity.

I use name brand alkaline 9V batteries in my active pickup guitars and change batteries about 3 times a year (I play pretty much daily). I’ll put a piece of masking tape on the battery and write the date installed with a sharpie.

I could probably go to changing twice a year but don’t want to risk a failure during a gig.

That would be handy in my gig bag, but shipping to the US is almost as much as the meter.

Everywhere in the US it is not available/discontinued.

Seems like Keith McMillen stopped producing it, it was distributed by analog man too but they say it was discontinued in 2020. Thomann probably has some old stock left. You can try emailing sales@keithmcmillen.com to see if there is any way to get one anywhere in the US. (the shipping from Thomann is actually pretty cheap, even though it's the price of the tester)
