3.6V PRAM Battery For Select
Desktop Systems.

Is your computer forgetting what time and day it is?

Macintosh computers contain an internal backup battery to maintain system settings, such as the date and time, when the computer is turned off . The battery may last up to five years though actual life is determined by shelf life of the battery and usage patterns of the computer. The batteries used in the Macintosh computers listed below are lithium, and are 3.6V.

When the computer does not retain PRAM settings (such as the date and time) after it has been turned off, this generally indicates a dead battery. Some Macintosh models, such as the Power Macintosh 7100 and the Quadra 605, display a black screen when the battery has failed and the computer is turned on.

Rating: 5/5 Still can get a battery for my old Mac January 8, 2016 Looked up on the website which battery I needed for my old G3 Power Mac, and they actually had it. It arrived promptly, was the correct battery, installed easily and is working fine.

Rating: 5/5 Super fast service September 29, 2015 My G4 was acting like it was possessed, restarting in the middle of the night and other problems. The OWC battery fixed all its problems. I can't afford a new computer, so OWC is crucial for keeping my old one going strong.

Rating: 5/5 Exact battery at a great price! September 27, 2015 Once again, OWC offers a great deal. I still use a G4 MDD PPC and this battery is used for the PRAM. Thanks to OWC I can replace this battery for a very reasonable cost - other suppliers ask 4 times the cost for this particular battery. From OWC I get a great price and the assurance of a fresh battery - not one that's been sitting on the shelf for a year. Thanks OWC!!

Rating: 5/5 Did it's job July 12, 2015 The new PRAM battery brought new life into an old machine, and corrected it's issues. If it lasts half as long as the old battery, it is well worth the cost.

Rating: 5/5 Resurrecting a Great Work Horse August 30, 2014 I happened into a wonderful Power Mac G4 system. As good as it is soon I saw a problem and with some help determined a new pram battery might be needed. My fitst thought was OWC since OWC solved my MacBook Pro internal hard drive issue with a great upgrade. The video showing how to make the necessary rapair is top notch. Very precise tnstuctions are the hallmark of the OWC video's and I can tell the effort makes any repair go smooth. While my pram battery replacement was a simple procedure without it I could have messed things up. To keep my Mac systems in great shape I trust OWC to provide me with the best products and video instructions
