Hello nickpapicc,   You should be able to contact Dell and ask for the Spare Parts department to get a quote for the battery:   Part #:D668J Part Desc.:ASSY,BTRY,PRI,MD32XXMD32XXX ASSY Battery Backup Unit   I'm not familiar with third party EU resellers. I'm in the US region. Hopefully someone in the region that has luck with third party sellers can help there.  
Hello, I got warnings from the console of a powervault md3200i of a customer. Both raid controllers batteries need to be replaced, but I was unable to find a website where I can buy new batteries for the powervault in Europe. Dell support website doesn't help. Any advice appreciated. Nick
