It uses a Li-ion rechargable battery - check the price of replacements before you buy.

That also has the disadvantage that you probably won't be able to swap batteries in the field as you can with dry cell AAAs.

Also worth checking if it can be recharged from 12V.

Steve and Marg,
What Mike said is well worth checking, I have a TX630.
Great radio. If I had my time again and with the wisdom of 20/20 hindsight, etc.
I'd have confirmed all of Mikes points and I'd probably have come up with a different radio.
My TX630 has a Li Ion battery of some 7.4 Volts and uses a desktop charging socket with an input of 15 Volts DC.
As Mike states, neither of these points are easy to deal with for in car recharging or field battery replacement which is really where you and Mike and I need to charge a portable radio.
I can probably get around the 15 volts by making a 12 to 15 Volt regulated power supply but the desktop socket will most likely prove to be a pain in the car.

Hi Geoff

It's worth trying your 15V charger on 12V it _may_ work and when your vehicle is running the system voltage will be around 13V5 which gives you a better chance. For the price of a couple of plugs from Dick Smith it's worth a go - there is next to no chance a low voltage into the charger would damage anything.

Hello Mike,
You are quite right. It's worth trying the unit straight from the cigarette lighter socket, I've got nothing to lose.
Time to get off by tail and give it a go.

I have a TX630 and do EXACTLY as Mike H suggested. From 1 (one) bar to fully charged is about 3 hrs driving time.
