My PowerShot A720 IS digital camera (from 2008) permits AA-size 1.2 V NiMH or regular disposable AA alkaline batteries. Can I use AA-size 1.5 V Lithium batteries?

The manual (pdf) warns against nickel-cadmium, but doesn't mention Lithium:

This camera uses AA-size alkaline batteries or Canon AA-size NiMH batteries. While it is possible to use a size nickel-cadmium batteries, performance is unreliable and their use is not recommended.

Thoughts?

EDIT: Here are the proposed Lithium batteries.

I've been using 1.5 volt AA lithium cells in my Nikon camera for some time with no problems. As long as the voltage is correct, I don't see any reason not to use them.

  • \$\begingroup\$ Interesting. I was curious about AA lithium, but had never used them before. Looking at this datasheet: varta-microbattery.com/applications/mb_data/documents/… , I find that they seem to be rated for \$1mA-10mA\$ loads, which is quite different from what alkaline and NiMH batteries support. \$\endgroup\$ – jonk Sep 9 '16 at 17:47
  • \$\begingroup\$ @jonk - Hi - FYI the battery you have linked is not a normal AA battery; it states "Nominal Voltage ... 3V" so it is different to what Peter Bennett is talking about. \$\endgroup\$ – SamGibson Sep 9 '16 at 17:52
  • \$\begingroup\$ @SamGibson: Thanks. I had just noticed that! I need to look at the right datasheets! \$\endgroup\$ – jonk Sep 9 '16 at 17:53

Canon's comment about the reliability of NiCd seems to be voltage related because NiCd has about half the output resistance of NiMH so I would think they are superior for high-current flash-type discharges and optical zoom motors.

Under that assumption your 1.5V Lithium cells would be fine.
