Does anyone have any parts info that would be able to tell me the difference between SOA battery # SOA821B200 and SOA821B100?

The reason I ask is I just bought a used 2000 Subaru Outback to replace my 1992 Subaru Loyale Wagon. I want to swap batteries if I can since I just got an Interstate MT-35 in the 1992 Subaru and my new-used car has an older battery. I looked online Interstate notes that the battery Mt-35 is compatible for both cars but the old battery is a SOA and it's the B200 and I don't know if it can go into the 1992 because online it indicates the battery is a B100.

Just learning about cars so be gentle LOL

Thanks in advance!

 

The B200 is larger and has more cold cranking amps (cca) 550. The B100 is smaller.for ther Justy and Loyale and has less cca (525)
hope that helps
