There are a number of issues that may be prevalent with the unit that you
have. This has to do with its design.

The default under load voltage may not be able to be properly matched in the
size type that it uses.
There may be an issue with the current source capability of the batteries in
the size type that it uses.
There may be an issue with any type of built in charger that your unit may
use.

If lithium batteries are not properly used, and or charged, there can also
be safety issues. It is best to follow the instructions from the
manufacture, if you want to have good product reliability, performance, and
safety. A good advice is to follow the instructions from the manufacture.

Just purchased a Sony Cybershot DSC-H1 digital camera.
It came with 2 NIMH AA batteries. The manual says...

You can not use lithium batteries. I have always used non
rechargeable lithium AA's for emergency back ups. Why
doesn't Sony want these batteries used?
