Lithium 9v batteries in pedals? ES Preamp?

[fuman]

I recently came into a good deal on some lithium 9v batteries. I could replace all my smoke detector batteries, but I will still have two left over. Can you use lithium batteries in a pedal drawing 9v power? In a guitar pre-amp? (I have a Taylor ES and from what I read they may not fit anyway, but I have another guitar with a Baggs and a battery bag and it would work for that).

I have only had to change my ES battery twice (the second one just happened) in about a year, playing regularly in church and goofing off at home.

Thanks

In my experience they work fine everywhere, though I've often been disappointed in how long they last relative to the claims and price. I have gone back to buying bulk name brand 9v alkalines at Home Depot for a little more than $2 each.

Should be fine. Here's a review of a 9V lithium battery marketed for pedals, etc., but the ones you have would be fine too:

Due to a misread post, I'm erasing my post…

If these were for smoke detectors, I think these are non-rechargable 9V lithiums, like http://www.amazon.com/Energizer-LA52...dp/B003VKOEBM/. "Recommended for smoke alarms, professional audio and medical devices."

Discharge curve for the battery above: http://data.energizer.com/PDFs/la522.pdf
Discharge curve for regular alkaline 9V: http://data.energizer.com/PDFs/522.pdf?page=2

You can see how the lithium has a flatter discharge curve until it peters out. The alkaline drifts down and down.

HI dha…

You are right - thought he was referring to rechargeable. I've used lithium in my Chorus pedal (non-rechargeable) and didn't see enough improvement to continue using them. That's hardly a professional test.

Thanks guys. I think I will stick with the Duracells.
