Hi Guys,
what specification of battery do I need for my 1956 Super 88? The manual says 62 ampere-hour but doesn't mention CCA or group. Thanks

 

The CCA is simply the rating for how long and how hard the battery can be drawn from at a certain temperature. The group is the fitment or size. If there is no listing I would measure the battery tray to see which battery fits. You can take those measurements to a place like a Costco and determine which fitment group will fit in your battery tray. Obviously you will want to consider side posts or top posts as well. A lot of times the CCA is limited by the size of the battery but most of today's automotive batteries would have plenty of Cold Cranking Amps for your application unless you plan on doing a lot of winter driving. Hope this helps.

 

Looks like it takes a group 24.
I am not recommending any battery brand, just giving you a link to the specs on group 24 batteries.

I don't know how important originality is to you. The "tar tops" are generally not easy to find anymore. The old group number was 60, but it's now obsolete. CCA is a newer type specification. My opinion is to measure the slot in the tray and get the largest, strongest you can get with the best warranty and the correct type posts and polarity and you will do fine. (A 27 "might" fit, but measure the tray to be sure.)(A 27F has opposite polarity.) I've done that for years in my '55. Try to take as many precautions as possible to protect the tray, bracket, & terminals from corrosion.
