Thanks for the ideas.
This is really frustrating. Having to resort to NiMH with 15 pics before camera shuts down.
I will see if I can find a local store I can take it to and try out a different Z712 and I'll take these batteries with me. I need to nail down the problem!
I bought it online through Dell after seeing it for just under $200 on bensbargains.net so I'll send it back as a last resort.
