Can I run a 5.5/4.7V 700mAH Walkie Talkie off a few AA's?

Hello,
I know this question is a little.... off topic.
But nonetheless, I have a question.
I own a Walkie Talkie that has a wrapped 5.5V/4.7V 700 mAH battery (i say that because the battery SAYS it's 4.7V but when I test it it is 5.5V. I don't know why.)
This battery runs out in about 10 seconds of talking. As you could guess, it's rather annoying.
I could replace it with AAA batteries, because they are the same size and would fit. However, AAA rechargeable batteries are.... RATHER... expensive. I wouldn't like to spend over $5 - 10.
I do have about 50+ rechargeable AA's on hand, and I would love to use those.
Is there any chance I could use those? I am very able in the ways of the DIY. (I built my own computer, have reconstructed Printers, made my own 12V battery from AA's, have assembled and fixed a DIY kit 3D printer... etc. etc.)
(In addition, i have 5+ other Walkie Talkies i'd like to use any answers on.)
Would I do damage to it if i put 4.8V battery in? (4 AA's)
Would I do damage if i put in to many volts?
As a side question, is there any way I could easily boost the range from around 5 miles to, say, 20+ miles?

Thank you so much, You all rock, Mr. Toaster.
btw, I want to use rechargeable batteries (these things EAT through batteries!!!)

Well if you're going to build an external battery pack, then you could use "C" or even "D" cell batteries! They all have the same voltage... 1.5 volts/battery.
But they'll run a lot longer.. or you can double up the "AA" batteries which should double the run time of your walkies.
As for your question about transmitting power. That is probably something you're not going to be able to do.

Do you have a picture of the battery pack? I think it might be a 6 cell pack. the only problem would be the size of the batteries.
You can easily make your own battery packs complete with wrapping them and all!
it's all about the size and how to attach them.

Can't send a picture, but they are AAA's and I've used normal AAA's to a high effect, but they run out really fast. I guess i should just go buy AAA Li-Ion's or something. The actual pack isn't really special, just some AAA's wrapped in (pretty much) black electric tape. but I was wondering if i could use a separate battery pack with AA's (or others) to make a more powerful battery pack (I don't care if it doesn't fit in the walkie talkie).
I guess my real question is: HOW much Voltage is TOO much voltage?
Btw, I checked my battery again, It reads out at 5.8V, and I ran it for a day, it when down to 5.1V. (I still need the solution for my other 6+ talkies!)
Thanks for the help!

Thanks for the prompt answer,
I wouldn't try to recharge inside the talkie, I would probably have to take the holder apart to charge them.
Btw, I have a working 3D printer, so I could print holders and such.
Thank you all!

That would kind of defeat the purpose, because i wanted them to be super cheap. But, I found a few Rechargeable AAA's and they work fine. Since it's four 1.2V batteries, (less than it supposed to be) it always says it's running on low, but that isn't a huge problem.
As for boosting the signal, I guess I'll just make a main base out of an RC and a few walkie talkies (I've done things like that before).
Thanks so much, MR. Toaster.
