I answer a lot of questions on Quora. Many of those questions are about automotive things that may be of interest to CarNewsCafe readers. Like this one.
Why are car batteries’ positive terminals larger?
My answer: There are three basic types of battery terminal used in most automotive. Both the Society of Automotive Engineers (SAE) and Japanese (JIS) posts are the conical “up off the top” type you’re likely referring to. The other is the side terminals with screw-in receivers.
