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?
Maybe this is the reason?
Lithium's can supply the high impulse current used to charge
a flash for example. However they do this at a higher voltage
than the recommended NIMH. IxE=P
If A 1.2 volt NIMH = 1, then a 1.5 volt lithium = 1.5625
So that a Lithium AA could potentially increase the wattage
of a flash by a factor of 1.5625
