Anybody using rechargeable 9-volts?

[hamerhead]

Got any advice?

I have advice but it mostly entails buying new batteries.

I normally just use the Energizer 9 volts but now wondering due to the evolution of newer Lithium batteries, if there are any "real" rechargeable 9 volt Lithium batteries 🔋?

Cuz THAT would be steller!

Time to Google ~

I looked into it and decided not to just because of the initial expense, as well as the voltage/current/runtime trade-offs.  I got a Volto which was fine for running a small integrated multi pedalboard for several hours but current output was low enough that it would occasionally make switching of the effects glitchy or uncertain.  Stumbled into that recent SDOD on the Pedal Juice and that pretty well put the rechargeable 9V idea to bed.

That said, i have a little adapter cable that has a 9V clip on one end and a standard pedal power plug on the other.  Could be handy one of these days.

Dammit about the '"9V" is the physical size/shape, not the actual voltage' thing. Apparently smoke detectors don't like 7.2 or 7.4 volts....

We used to do for children toys, where plenty of reloads were needed. Haven‘t used them since. For the most part batteries do it nicely.

Can Eric Johnson tell a difference in the tone of a smoke detector based on which batteries are used?
