.... providing you account for the third terminal correctly. Anyone here know its function?

Not a clue but best guess is a thermistor for when it's on the charger which goes with it. My Canon batteries are two terminal.

Yes it's a thermistor, i have the similar type of battery in my canon camera ,it measures between the Negative terminal.

 

Thanks for the info.

 

Rechargeable AAs cannot produce anywhere near the current that a similar capacity Li Ion can. They may not run the camera at all. You would be batter off to make an external pack using a standard size Li Ion battery.

I experienced that problem when I tried ti replace NiCad batteries with smaller lighter NiMH having twice the capacity. They would not run the drill at all.

Can't a camera be designed around AA/AAA batteries taking into account it's characteristics of low current, etc.

I agree with the others. I have two Canon cameras. EOS 10D and EOS 7D both us the rechargeable Lithium Ion battery packs. I just always keep an extra battery fully charged in my camera's bags. You have, as mentioned a 3.7 volt 600 mAH battery. You are not going to be able to replace that battery with AA let alone AAA batteries. A two pack of your battery cost about $15 USD and a new battery and charger about the same. Leave your camera body alone and do not try and modify it.

Years ago I had a Nikon that used AA batteries. It literally ate them. I needed a bag full of batteries. AA and AAA batteries deliver very low current and in a camera have a short life.

I had a similar problem with Sony Cybershot H300, apparently it was due to a bug in the firmware, resetting/formatting the camera resolved the problem, maybe you could have tried formatting the camera.

Replacement batteries for Canon point and shoot cameras are readily available very cheaply. It makes no sense to do anything other than buy one or two new ones. I can’t imagine why you want to undertake this.

To future proof, for a time when those batteries will not be sold anymore.

My first and by far, one the best I ever bought, a Nikon, used its own rechargeable batteries. The manual said that it could be used with AA (or AAA) batteries (I never know who is who there) but for very few pictures. I recall doing that once or twice in an emergency in my work. Carried always a pair fully charged to avoid that.

AA are the bigger ones, they are like crayons, AAA are the smaller ones, AAA are like half cut pencils.

 

To future proof, for a time when those batteries will not be sold anymore.

If, somehow, your camera is still operational when the batteries are not available you have yourself a project to convert it to some other lithium battery but it really doesn't make any sense to do it now, nor does it make sense to try to run it on alkalines.

The very poor runtime, the very high cost, and the very inconvenient size are not worth the possibility that you won't be able to get the battery.

 

..... nor worth the risk of damaging the camera in the conversion process.
