It's called a "power supply" or the dollar store! hahaha
I haven't tried any rechargeables that work great in pedals. Some of the stompers only work right with alkalines, which rechargeable's aren't... most are lithium or nickel hydride and the other pedals had a super short life span... like two or three hours in a distortion box.
Had some of the old "Renewal" packs back in the day, there was some other charger that would work with regular batteries... can't remember what else.
Good to know. A friend of mine is hell-bent on using rechargeable batteries, and as much as I've tried to steer him in the A/C adapter direction, he remains reticent to do so.
Don't rechargeable batteries drain or discharge even when not in use?
...and when they're low, they'll just quit on you suddenly.
For reliability issues I wouldn't use rechargeables... definetely get a power supply... you can keep an alkaline in your stomp box when using the power supply without it draining...
I don't know of anybody on a pro level who uses rechargeable 9 volts in anything... be it guitars, pedals, or the all important wireless lifeline.
About two years ago I spent, I think it was about $45 on a batch of 9-volts and when I realized how long they were gonna last, and how much I've spent over the years... my next thought was; "How much is a pedal power again???"
I used to use recharable for my Wah .It was nothing special ,and not btter at all.
The problem with Ni-Mh is that they are not reliable ,have memory effect etc.
You have to wait till sanyo comes with the new eneloop 9 v version. They come already charged and have no discharging/memory effect problems.
I posted a thread about a low discharge version of a 9volt battery on Candle Power Forum a year or so ago. I was told that since 9volt batteries basically consist of multiple button cell batteries inside of the 9v casing there will never be a good Eneloop version.
There is a Uniross Hybrio 9 volt that claims to be a low discharge version but have never found a source to even buy one in the US. Some have good results on the lithium iPower 500mAh 9volt cells. They are like $15 a pop though and they will only have a finite useful life even if they are never used.
Many people are using these lithium rechargeable 9volts in wireless mics, so I assume they'd be good for active pickups and also wireless transmitters for guitar as well.
I will add for a few years I was using older Ray O Vac NIMH 9volt cells in stomp boxes but having to recharge often was a PITA. Much happier with a Pedal Pad II and Dunlop DC Brick.
There's definitely a difference between alkaline batteries and those that aren't. Some electronics that require alkaline batteries won't even function properly without them. I'd either use alkaline batteries or (probably) an AC adapter of some sort.
Jerry, you might want to leave those sort of details in off-topic.....
