Once upon a time, car batteries were something of an afterthought for manufacturers. For the most part, manufacturers would just pick a battery that provided adequate cranking amps and storage capacity, and call it a day. Now, though, batteries are an integral part of the system, and cars use sophisticated charging strategies to keep them topped up. For that reason, you mess with battery size and specification at your and your charging system's peril.
A 24F car battery measures 8.625 inches tall, 10.93 inches long and 6.75 inches wide. Lead-acid batteries of this specification weigh in at a pretty significant 43 pounds, and higher-quality units can offer an equally significant 700 cranking amps at 0 degrees Fahrenheit. Combined with its 125 minutes of reserve power, that makes this battery a good choice for those who live in the Northern reaches of the country, and drive trucks with large, high-compression gas engines. Cheaper batteries of this spec offer about 600 cold cranking amps and 110 minutes of reserve capacity; that's still enough for most applications, but more is always better.
