 Not much more than other batteries. If you check the Maxim's site on
power management section you'll find a few hundreds of chips which
will offer you 3.3V to 5V from 1.8V. The same on Linear Technology and
National Semiconductors.
Have you seen 1.8V lithium battery with great capacity with resonable
price on the market ?
