Cateye Solar and rechargeable batteries
I have an old Cateye Solar cc-2000 that works great. It calls for SR44R , which are rechargeable silver oxide (AgO) batteries. When I searched on Amazon , these batteries are no longer made, so I bought the replacements, which are 303/357. I bought the Duracell version, which are alkaline. I just noticed this same battery comes in a silver oxide version, although it doesn't state in the description that they are rechargeable.
Is there something inherent in the AgO battery design that makes them rechargeable, or do they explicitly have to be made a certain way to recharge? Do you think if I bought the AgO batteries they would recharge via the solar cells in my Cateye? The alkaline batteries work fine, but they last only about 1 season, they'd probably last longer if I could remember to remove them in the winter.
Thanks
Tom

Thanks for the response Jose, I guess I should have been clearer. I know that alkaline batteries are not rechargeable. My question is, are all AgO batteries rechargeable, or do they specifically have to state in the specs that they are rechargeable? I just don't know much about AgO battery technology.

Just for the record, I used LR44s for a few years. They lasted a year or 1000 miles. That is, I rode 1000 miles/year, and I installed new batteries at the beginning of a season, and they weren't working at the beginning of the next year. IOW, maybe less than a year if you do more than 1000 miles/year, maybe more moiles if you do more than 100/year.

according to wikipedia, silver oxide batteries are primary cells, and are not rechargeable.

Maybe just install 357 batteries and see how that goes, and skip the recharging phase?
I do recall the Cateye solar computer.... my brother-in-law had one. Honestly, that was so early in the era of bike computers that expectations were very low, and that design was still a commercial failure. If you want a nice vintage bike computer with a so-so battery life, I recommend one of the Avocet models. I'm still using 3 of them and get about a year of life from the 357 battery.
