I wolud like to know what is the differece between 10 year and regular battery. 10 year is lithium, am I right? And can the 10 year battery be replaced by regular one? What is the difference in price?

afaik all batteries today are lithium, at least all those CRxxxx types. there is no such thing as a dedicated 10 years battery. according to casio the 10 year lifetime got something to do with a "special hardware development in the module", but I don't buy that, for me it is simply marketing BS.

take a mudman G-9000 and a G-2900 for instance: both use exactly the same type of battery - a CR2025. in the mudman case casio claims an approx. lifetime of about 3 years, in case of the G-2900 they speak of "10years battery", so go figure....

hmmm, same battery? That's odd. I did't know that. Maybe because mudman has some features that consumes more power? But than all basic model sholud have 10y battery life. I red that some of old g-shock have batteries over 10 years without replacement. Also I saw some analog casios with "10 year battery".

a CR2025 3 volt lithium battery has an average capacity of about 170mah. thats quite a lot for such a small, low power consumpting item like a wristwatch. of course it all depends on how often one uses el-backlight, alarms etc. but I'm willing to bet, that a CR2025 is capable of running 10 years in more than 90% of all watches (with execption of ABC watches).
