Best rechargeable batteries that are the CORRECT size!??

[kwo]

Alright, I'm having a problem here.

I like rechargeable batteries - have some PowerEx 230mAh I bought from Thomas Distributing that I've been very pleased with (average 1.5 year life - heavy use...)

Good batteries......BUT.

They are slightly bigger than normal 9v alkaline batteries and some of our audio equipment will NOT fit them.

So, I need to find some good NiMH batteries that are the EXACT same size as normal alkaline's (e.g. Duracells, Eveready, etc...)

Any suggestions of what brand and where? I'd like to get something >200mAh, if possible.

Thoughts/comments appreciated...

Does the equipment have a pullout strap? Some rechargeables are slightly larger than their alkaline replacements. Adding the pullout strap requires you to shoehorn the darn thing and then you break the strap extricating the depleteted battery. Been there, done that with our Nady's.

Most of the shells are sonic welded at the top where the terminal plate meets the body. The body is typically reaction injection molded (RIM) and has semi-thermoplastic characteristics.

So if you have the time, you can hot knife the sonic weld fillet around the terminal plate and remove the actual nest of cells and terminal plate from the body and possibly shrink set the body (moderate amount of skill required!) or sand it. The latter could possibly be performed with the nest in place but you should still be careful always. Overheating the cells or shorting their output is never a good thing.

Good God, man..are you insane?

I *buy* batteries, not modify them to power a starship!

Nope, I have a bunch of PowerEx batteries and they fit all of my equipment. They feel a bit heavier though!
