I'm not knowledgeable about batteries, perhaps 24v vehicle batteries are common, but I don't think that battery is going to be starting any heavy equipment anytime soon.
I did see a pic of an interesting battery in a vintage 124 rally car.

Looks like it could be a 12v & 24v battery, connected as a 24v battery?
Maybe 6v and/or 12v?
According to my 1974 shop manual, there is a place on the X1/9 that uses 24 volts. The procedure to remove the windshield calls for putting two 12 volt batteries in series and connecting them to the two terminals under the center of the windshield. Apparently, there is an embedded heating element around the windshield that you activate by putting 24 volts across it and wait until the adhesive gets hot enough to remove the windshield.
Dom, those "double-D" shaped posts are interesting. What type of cable clamp is used on them?They also give you different terminal shapes

The "Banner" batteries kind of remind me of the ones here that have both top and side terminals. And speaking of side terminal batteries, if you think about it that is a vast departure from the traditional type of posts. Do they have them (side post) in Europe? I don't recall ever seeing any on my various visits. I've always thought of it as a American car thing.
Regarding the "Banner" batteries having more configuration options. I think it's a bit weird that there are so many variations of battery post layouts in America. It would seem more efficient to have a couple of basic battery specs, and have all car makers design around them. I know that's a big ask, but not when considering the battery is a consumable item, a rather expensive one, plus an environmental hazard. Can't tell you how many times I needed to replace a battery only to find it isn't kept in stock. If more parts lines were streamlined the cost of maintaining a vehicle would be reduced dramatically. For example, a few years ago Bosch was bought out by a larger conglomerate (or should I say, added under a bigger umbrella). The new parent company decided to reduce the number of individual part numbers by merging lots of items into one "universal" part. The overhead was reduced by an insane amount, making the brand viable again. Imagine if all automotive companies did that. But car makers tend to do the opposite. They want to make everything "proprietary" so you have to buy replacement parts from them. However the aftermarket always copies the parts so it only serves to increase the cost of doing business for all companies involved. Naturally that increased cost is passed on to the consumer.
Hi Jeff,
unfortunately, I don't know much about these double-D terminals. I know that the normal clamps will work on them but as to why they have flat sides I'm not sure. I certainly can't find any examples of clamps that are designed for such a terminal. The side post batteries certainly seem to be more of an American thing (although certainly a good idea from a space / packaging perspective).
Reducing the number of product variants is a good idea for both the consumer and the vendor and reduces the overall waste in the industry. I remember one of the first things that Steve Jobs did after retaking the reigns at Apple was to reduce the number of models by about 70%. When I worked for Hewlett-Packard, I remember wondering how we ever made any money with the number of SKUs that we supported.
Cheers,
Dom.
