The online manual (page 6) says this about the battery:
...
"1 Camera uses the Rechargeable
Lithium-ion Battery
* When shipped, the battery is not
fully charged. Always charge the
battery before using it."

The manual also says that rechargeable Ni-MH batteries are okay for use as well as alkaline batteries.
If you are curious about the care and feeding of Ni-MH batteries: https://www.batterystuff.com/kb/articles/battery-articles/proper-care-and-feeding-of-a-nimh-battery.html
So, either the Duracell(s) or the Sanyo(s) or the Panasonics should be okay.
Back in the day it was common to use NiMh rechargeable AA batteries in cameras that took AA sized cells.
Have a look around at places like electronics component suppliers or model/hobby shops for them and a suitable charger.
A good example (and fairly easy to source) is the Sanyo Eneloop rechargeable AA batteries (1900mAh), they have their own charger and work well in high drain situations and they also maintain a good charge when left unused. There is also an Eneloop Pro now with higher capacity (2500mAh).
Here is a link to a pack that has the charger (it also does AAA) and four AA cells, look for them in a local shop or local amazon, etc.

Welcome to the forum.
According to an online manual, your camera originally came with a rechargeable battery, I am guessing a lithium-ion type based upon the way the manual presents its information.
Listings for the Panasonic battery you say you are using decribe it as being used in low-drain situations, so it may not be best suited for cameras. You could try removing the batteries after you use the camera, at the risk of losing the stored time, date, etc. information — you would need to reenter it when you are ready for the next session.
Or you could try the Duracell batteies you mentioned. They sell rechargeable batteries specifically for your camera which hopefully would work for you.
