Mac Pro 2010-2012 battery replacement

I need to replace the Internal Backup Battery in the Mac Pro 5,1. In the manual it specifies a BR2032 Lithium battery. However, that battery doesn't seem to be available any longer. The CR2032 seems to be a replacement for the BR2032, but I'm trying to make sure that is indeed the case. Has anyone used the CR2032 battery successfully in the Mac Pro 5,1 without a problem?

Mac Pro, OS X Mavericks (10.9.4), 3-1TB HDs, 2-2TB HDs, NEC PA271W

The BR and CR are different but interchangeable for most application

What Are The Differences Between 2032 Battery Chemistries?

There are a few common battery chemistries that have an effect on a battery’s energy density, performance under varying temperatures, shelf life, rechargeability, and gravimetric capacity. Each battery chemistry performs better in certain situations as opposed to others. In this brief article, we’ll decode the abbreviations and show you the advantages of different battery chemistry types.

CR Battery Chemistry
CR denotes Lithium Manganese Dioxide (LiMn02). These kinds of batteries are often used in cameras because of their high energy density and ability to perform in low-temperature environments. CR batteries are also used in smoke alarms and security applications. Anything that requires a small high-powered battery probably uses Lithium Manganese Dioxide chemistry.

CR Batteries:

  1. Provide a high density charge in a small package
  2. Work well in digital cameras and computer peripherals
  3. Can handle low temperatures relatively well
  4. Discharge quickly and evenly (for a camera flash)
  5. Have a great shelf life
BR Battery Chemistry
BR denotes Lithium/Carbon Monofluoride Li-(CF)x. Batteries with this kind of chemistry are well known for their superior shelf life. BR batteries often last 7 years on the shelf. They have one of the slowest self-discharge rates of any battery on the market. That’s why they are commonly used in clocks, pacemakers, and not surprisingly, long range missiles.BR Batteries:
  1. Last up to 7 years on the shelf
  2. Have been used in space applications since 1976
  3. Can be found in pacemakers
  4. Function up to 85 degrees Celsius
  5. Usually discharge less than 0.5% each year
