rechargable battery inside guitar

[Fp-www.Tonepad.com]

After reading some of PSW's post on the sustainer, I think it would be a great idea to have a rechargeable 9v battery inside the guitar and just add a plug somewhere on the guitar backplate (or elsewhere) to recharge it.

This way you'd have 9v in your guitar for ANY circuit you'd want.

How would one go around doing this? I have yet to research on battery chargers, but I'd appreciate any links/hints.

So you'd have guitar signal+9V? Battery-free effects?!? Awesome! Could you just put a 9v in a stompbox and put it before your effects, too?

I was thinking having available 9v inside the guitar for the sustainer OR any other in-the-guitar circuit (buffer, booster, stuff like that).

I figure it would be just as useful to have a rechargeable battery in a box that would be the power source for the rest of the pedals on stage and that you would charge before.

I made a phantom power box that feeds my preamps in my guitars. Works perfectly

lightware use rechargable batteries

but I think that this idea is good only when you have more consumation of power.
If you have some booster/preamp with less than 1mA, better is to use normal alkaline battery, because his live is about year and more, and in all NiCD/NiMH batts, capacity go down with ca 1% per day, and you must recharge the battery often.

EMG recommendet to use alkaline battery with your active pickups exactly because you can use one battery for abouy 6 months

As far as a jack goes -

If you are going to use a stereo (TRS) jack on the guitar to turn the battery on and off - you may be able to wire a TRS 1/4" jack directly to a wall-wart type trickle charger ( + to tip and - to ring ).

I've been told this works well with EMG's however I do agree that the current state of rechargable batteries is not a great option unless you plan on charging frequently.

I remember talk about the radio controlled 9.6V packs. Just clip it on and charge.

What about the IC3 batteries? 15 mins and you are ready to go!

 a few years ago i built a headphone amplifier  from the construction page at minidisc.org. Although i ended up using a regular battery in mine, it has instructions for a rechargeable battery setup with jack.  Sounds like maybe what you're looking for:

Cool idea, but I think it would be very limited by the amount of available current (mah). Especially if you have a lot of pedals on your pedalboard, like me. Maybe if you had a big battery pack...
