Camera Found an old Sony Cybershot DSC-W5 in cupboard, need help for testing it.

So, while sorting out an almirah with my father, I found an old Sony Cybershot DSC-W5 there. It might be around 15 years old at this point. I wanted to test it, but sadly I didn't have any batteries for it.
I looked into the manual online to find which type of battery it takes. But I wasn't able to find the batteries mentioned in the manual in stock anywhere.
I got some results for some duracell and Eveready batteries, but I'm not sure if they will be compatible.

So, can anyone please help me in finding which batteries will be compatible with it, so that I can buy them.
I haven't checked in local market yet, if anyone knows which batteries are available in local market as well, like the brand and model then please do tell.

Thanks.

Does the manual show battery as NP-BG1

On the sony international website it showed as NP-BG1, but when I asked my father, he told it uses batteries similar to the ones we use in remotes.
So then I checked on sony india website, where I found another manual, where it showed the AA batteries I posted in the pics.

These will be safe right? I wasn't able to find the type of these Duracell batteries, whether they are HR6, ZR6, etc.
I don't know much regarding batteries.

What you are mentioning (NP-BG1) and what your dad remembers (AA) are totally different battery types. Post the picture of battery compartment to clear the confusion.

I know they are different, I checked online.
I have attached the picture of manual where is shows that it takes AA battery. Please swipe in the imgur link.
I can also post a picture of the compartment when I reach home.
