Are you familiar with the letters on different batteries and what they mean? Getting to know those letter designations can help inform your purchasing decisions. A “24,” a “F” or an “R” battery all have one thing in common: their dimensions are always identical.
But these labels also hint at something else – each of these designs denotes either a flat-top configuration (the F) or reverse polarity (the R), plus other power-related specs like voltage ratings and capacities too!
In this article, we outline the key differences between 24 vs 24F vs 24R so that, armed with knowledge, you can make informed purchases best suited to your needs!

What is Group 24 Battery?
Group 24 batteries are the go-to choice for auto and truck owners alike, not to mention industrial or marine applications.
Deep-cycling designs make them perfect for running extra equipment while engines idle or when maximum crank power isn’t needed. Some users even rely on these batteries as dual-purpose units: starting and deep cycling! But their capacity drops a bit compared to powered starters; just keep that in mind before you buy one.
Key Features:
- Dimensions: 10,25 × 6,81 × 8,88 inches.
- Reserve capacity: 130-180 minutes.
- Cold cranking amps: 250-900 CCA.
- Capacity: 66-110 Ah.
- Weight: 43-57 pounds.
24 vs 24F vs 24R Battery: Key Differences
It is essential to know the differences between Group 24 batteries and their variations in order to ensure that you are getting the best unit at the right price. Here are the main features of Group 24, Group 24F, and Group 24R batteries:
Dimensions
| Group | L x W x H (mm) | L x W x H (inches) |
|---|---|---|
| 24 | 260 x 173 x 225 | 10,25 x 6,81 x 8,88 |
| 24F | 273 x 173 x 229 | 10,75 x 6,81 x 9,00 |
| 24R | 260 x 173 x 229 | 10,25 x 6,81 x 9 |
Group 24
BCI Group 24 batteries are essential for those with trucks, SUVs, and vans. These standard-sized AGM (Absorbed Glass Mat) units offer terrific value in terms of reliability while offering minimal maintenance needs. They offer standard dimensions and an assortment of different ampere-hour.
Whether you’re needing something to support an alarm system or a boot light—even providing internet service during transit—these Group 24 offerings should fit the bill! You’ll be surprised at just how much they can do!
Group 24R
Group 24R batteries feature the same dimensions, uses, and specifications as those of Group 24 batteries. However, there’s one major distinguishing factor—the positive terminal position!
Unlike regular Group 24s, whose plus sign is on the left side, this subgroup has it located to its right instead—hence “reverse polarity,” or simply “R”! Even though they look similar from afar otherwise, for electricians and technicians alike, having a keen eye always pays dividends during installation projects & repair works — orientations matter after all!
Group 24F
Group 24F batteries—they’re special! They come in two varieties: flooded and sealed. Perfect for cars, boats, RVs, you name it.
What sets them apart? Their terminal posts are flat; they are longer and wider than the other Group 24 batteries (but the same height). Best of all, lead-acid and AGM technology mean these eco-friendly powerhouses don’t require a lot of upkeep or maintenance. So if you need something reliable to get your project off the ground, go with Group 24Fs!
The Bottom Line: 24 vs 24F vs 24R Battery
What does 24R mean on a battery?
A 24R battery has reverse polarity, which means the current flows in the opposite direction from normal. It is important to ensure that any car or other electric device using such batteries is rated for use with them.
What does 24F mean on battery?
The designation “24F” relates specifically to automotive batteries and indicates dimensions: it’s 10.75 inches long by 6.8 inches wide, and 9 inches tall (with a flat top).
Which cars use 24F battery?
They are most commonly used within Nissan, Acura, Honda, Infiniti, Lexus, and Toyota vehicles, but also more widely across tractors, trucks, motorboats, airport tugs, forklifts, etcetera!
What does R mean on battery size?
The R denotes that the negative terminal is on the right side, meaning that its positive pole has been reversed or flipped to be placed on the left side.
Is a 24R battery the same as 24F?
No! Although they may fit in the same space due to measurement similarities, they are not completely interchangeable since the terminals are reversed.
The Bottom Line: 24 vs 24F vs 24R Battery
In summary, the 24, 24F and 24R battery types are specialized for unique purposes. Each of them offers distinct advantages suited to different applications; from energy conservation abilities with the 24 type to size optimization benefits in both the 24F and 24R versions. Ultimately, you will be able to make an informed decision on which setup best suits your needs.
