This doesn't really apply to me, but I am curious. I have heard that some ELT's are "rechargable". Is this true? Do these rechargeables simply use off-the shelf rechargable batteries that can be replaced when their lives are finished? Do they require special recharging equipment? Does this move them into the non-owner maintenance category?

Also, are there any ELT's that require dissassembly to replace/recharge the battery?
