Hi @Diamantis 

Welcome to the Sonos Community!

The CR200 is long discontinued and unsupported by Sonos - we have no replacement batteries for it to provide to you.

Your only chance would be to buy some third-party batteries that have the same specifications (and connectors?) as the original. There are probably many sites you could get these from, but I can only think of Amazon.

I did search, but I could not find any specifications for you. Someone in the community may be able to help though - some still have the CR200 in use.

I hope this helps.

eBay UK, there is a seller on there.

I was able to find a bunch of batteries by searching for “uk sonos cr200 battery”. (I’m in the US)

eBay - I always forget about eBay!

Thank you

i will check online
