Underneath the pretty aluminium box, Apple's RAID Card batteries are just bog-standard lithium polymer cells with some control gear. When they fail after a year or two in service you can bet the £££ you'll fork out to replace it that the cell isn't dead, but instead has got itself into a stuck state where the RAID card is confused about what to do with it. You are bidding on a LOT OF 4 Apple Mac Pro RAID Cards w/Rechargeable Battery P/N: 820-2591-A. They were WORKING PULLS, but I believe they will need replacement batteries. This Card will work on Mac Pro Early 2009, Mid 2010 and Mid 2012. Choose from: LaCie 16TB 2big Dock Thunderbolt 3 RAID Storage,LaCie 8TB 2big Dock Thunderbolt 3 RAID Storage,PROMISE Pegasus32 R4 16TB RAID System.

Best Raid Card For Mac Pro
Got a mac pro raid card in my macpro and i have configured 2 x 1TB drives as Raid 1.
I am concerned at the frequency at which the Raid utility calls my attention to a battery problem. Last week i waited 12 hours while the raid utility conditioned my battery. Today i received a red light warning message:
'Battery failed (code 0x#0 = 18)'
and then write cache was disabled due to insufficient charge.
My Raid utility seems to disable write cache to insufficient charge all too regulrly. How often does this normally happen? How long should a Raid card battery last?
The raid card is less than one year old and i am surrprised at how many times ive had reports of insufficient battery charge in the raid.
I'd love to hear other peoples experiences ether with similar battery life or whether your battery is operating charged without these problems?
Should i get the battery replaced?
Cheers
