I’ve got a new Rechargeable Battery to my Mac Pro Raid Card, but i don’t know how to install it ?

Remove the Raid card. There should be three screws holding it place. Just take them out, replace the battery. Here’s a PDF from Apple on how to do it: https://manuals.info.apple.com/MANUALS/0

Hi. I made a download of the PDF regarding instructions for changing raid battery. Thank You very much My raid A1247 has a battery EMC No.: 2156. I find online many batteries with different models of batterie (ex.: Apple Mac Pro RAID Card A1247 w/Rechargeable Battery A1228 OEM Box 639-0108). Are they suitable for me? can I use them successfully? My MAC PRO dates from early 2008. Thank you very much for your help and forgive my English. Renato Quadroni
