James Owen — Tue, 13 Dec 2022 22:20:07 +0000

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:

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?

BCI Battery Group Size Chart

James Owen — Tue, 06 Dec 2022 16:39:11 +0000

The BCI battery group size chart is a handy tool to help you select the right battery for your car. With batteries classified by specific BCI groups, it is easy to find the right size and performance for your needs. The Battery Council International (BCI) organization allows different manufacturers to produce batteries with the same specifications. This way, you can be sure that the battery you purchase will fit your car and perform as expected. Here is a guide to the BCI battery group size chart to help you make an informed decision when purchasing a new battery.

What Are Battery Group Sizes?

The concept of “group size” is primarily used in North America and refers to a battery’s physical dimensions. The Battery Council International (BCI) created the group size designation. These dimensions include the battery’s height, length, and width, as well as the polarity of the terminal.

Typically, the group size is stamped on the battery case. The group size designation is important because it ensures that the battery you purchase will physically fit in your car. If you don’t consult a battery size chart, you might purchase a too small or too big battery for your car. That would make it difficult, if not impossible, to install the battery correctly.

In addition to the battery’s physical size, the group size also includes the polarity of the terminal. The positive terminal is either on the left (L) or right (R) side of the battery, as you’re looking at it from the front. It’s important to know the polarity of the terminal because you need to connect the battery to the car’s electrical system. The polarity must match up, or you risk damaging your car’s electrical system.

Group 24 Batteries

Group 24 Batteries are mostly available as general-purpose batteries that are ideal for use with medical and security systems, large UPS systems, wheelchairs, vehicles, and some industrial applications. They are typically ideal for deep-cycle float and standby applications.

They are, however, also used as starting and cranking batteries in some applications, but rarely. These batteries are roughly 10.25 long, 6.875 wide, and 8.375 tall. However, these dimensions vary slightly between subgroups, so choosing the right battery for the application is important.

The most common Group 24 battery chemistry is AGM SLA. Still, they are available in various chemistries, including lead acid, gel cell, and lithium-ion.

Group 26 and 26R Batteries

Group 26 and 26R batteries are starting batteries used mostly in smaller trucks, SUVs, smaller boats, power generators, and other similar applications. These mid-range batteries have similar dimensions and electric features. The only difference between the two groups is the orientation of their terminals. Group 26 has the positive terminal on the left side, while Group 26R has the positive terminal on the right.

Group 26 batteries are roughly 8.19 inches long, 6.81 inches wide, and 7.75 inches tall. Most of these batteries are lead-acid flooded/wet batteries with a 20-hour capacity of 50 Ah. AGM and gel-cell batteries are also available but less common. A lithium-ion battery is also an option but is not as widely used.

Group 27 Batteries

Group 27 batteries are mostly deep-cycle batteries used in cars, off-the-grid, marine, RVs, and other similar applications. They are typically available as AGM, SLA, and spill-proof batteries, which can be mounted in almost any position. Most of these batteries have 20h capacity in the 66–110 Ah range and can provide 600–1000 CCA (cold cranking amps), 140–220 minutes RC (reserve capacity), and similar electric features.

The physical dimensions of Group 27 batteries depend on the exact battery group because subgroups include 27F and 27H. Even though they are very similar, the dimensions may be a little different, so it is important to check the size of the battery compartment before buying the battery.

Group 31 Batteries

Group 31 batteries are large and powerful, mostly used in electric vehicles, off-the-grid applications, marine applications, and other similar uses. Their 20h capacity is 75-125 Ah, providing 750-1250 CCA and 150-250 minutes RC. These size batteries are available in lead-acid, AGM, flooded cell, gel cell, and lithium varieties. Lithium Group 31 batteries are more popular because of their chemistry and electronic advancements. However, they are more expensive.

You could get true starting lead-acid Group 31 batteries, but they are rare. Since manufacturers tend to label some of their models as “starting” or “cranking” batteries, it is important to note that these batteries are designed to be dual-purpose with slightly emphasized “starting” characteristics.

Even though they are dual-purpose, they don’t have as good starting currents as true starting batteries, but they are better than deep cycle batteries. The deep-cycle group 31 batteries are designed for electric vehicles, off-grid applications, marine applications, and other similar uses that require deep discharge and cycle operations.

Group 34 & 34R Batteries

Group 34 batteries are considered powerful, and their features depend on their intended use. They are commonly used in automotive, marine, and industrial applications. They have a 20-hour capacity of 50-75 Ah, a CCA of 750-900, and a reserve capacity of 100-145 minutes.

Group 34 and group 34R batteries are the same in size and power; the only difference worth noting is the orientation of their terminal posts. While the 34 group has a positive terminal on its left side, the 34R group batteries have their positive terminal on the right, which is why there is the letter “R” after “34”.

Most brands manufacture both the 34 and 34R versions. Therefore, if either is required, purchasing them online would not be a problem.

Group 35 Batteries

Also known as Q85 batteries, Group 35 batteries are very versatile and can be used in many applications. Like group 31 batteries, they are often used as starting or dual-purpose batteries in cars, trucks, SUVs, RVs, and boats. They are also popular in UPS systems, wheelchairs, security system backups, and more.

AGM and gel Group 35 batteries are the most popular lead-acid batteries, but lithium iron phosphate (LiFePO4) batteries are slowly becoming more popular, especially in deep-cycle applications.

The Group 35 batteries are medium-sized, with 20-hour capacities in the 44–65 Ah range and 620–850 cold cranking amps (CCA). They also have a reserve capacity (RC) of 90 to 130 minutes.

Group 47 Batteries

Group 47 batteries are medium-sized batteries. They have applications in the automotive and industrial fields as either cranking or dual-purpose batteries for starting mid-range engines. They are also known as Group H5, L2, and 55L2.

A Group 47 battery typically has an MCA value of 700–750 Amps, a CCA value of 600–630 Amps, and a 20-hour capacity in the 50–60 Ah range. These batteries weigh between 38 and 42 pounds and have a reserve capacity (RC) of 100 to 115 minutes.

Most Group 47 batteries are spill-proof AGM and hence maintenance-free. However, other cell types are also available. When the battery is facing the user, its positive terminal is on the right side. A good AGM battery from a reputable brand is recommended when looking for a Group 47 battery.

Group 48 Batteries

Group 48 batteries are mid-range batteries. Nevertheless, due to similarities in size, batteries labeled as H6, L3, or 66L3 are still considered BCI Group 48 equivalent batteries, and the reverse is true.

They are often used as automotive, industrial, and marine batteries. They are helpful as starting or dual-use batteries, especially while the main engines are turned off or the mains’ power is absent. Many of the Group 48 batteries have a spill-proof, maintenance-free design. They also have increased resistance to vibrations and mechanical shocks, contrary to the older lead-acid batteries.

These batteries typically provide 60-72 Ah of power and have a CCA rating of 720-800 Amps. They also have an MCA rating of 800-930 Amps, an RC value of 120-140 minutes, and weigh between 45 and 54 pounds.

When making an order, it is vital to confirm the battery’s nominal capacity and its MCA, CCA, and RC ratings, together with terminal orientation and type.

Group 49 Batteries

Group 49 batteries are the preferred car or truck batteries. They are used as both starting/cranking and dual-purpose batteries. They power different loads while the main engine is turned off, similar to various winches and multimedia devices.

BCI Group 49 and Group H8 are considered interchangeable. However, they have several differences, especially in size. When trying to replace the H8 battery with the Group 49 battery, it is essential to note that BCI Group 49 batteries are slightly bigger and therefore require more room in the battery compartment.

Group 51 and 51R Batteries

The batteries are typically dual-purpose or automotive starting batteries. They are mostly used as auxiliary batteries in places requiring consistent and stable power sources. The dimensions are as follows: 9.374 x 5.0625 x 8.8125 inches (23.8 x 12.9 x 22.3 cm).

But the sizes of this group of batteries are not always the same because manufacturers have changed them to fit a wide range of applications.

The difference between the 51 and 51R batteries is only in terminal placement. In 51R, the positive terminal is placed on the right side, unlike in 51, where it is on the left. Otherwise, all other aspects, including capacity, features, and size, are similar.

Group 65 Batteries

Group 65 batteries are mainly dual-purpose automotive batteries, but they are also used for marine and industrial applications. They are usually manufactured with the AGM technology that helps to resist vibrations and spills. However, the lithium-ion types are slowly becoming more common and offer many advantages over other battery types.

Typically, these group batteries provide between 70-75 Ah 20h capacity, 130-150 minutes RC, and 750-950 CCA. Some models can reach up to 1100 amps.

Group 75 Batteries

These are light industry and automotive batteries that are mainly meant for dual-purpose or starting batteries with awesome starting features. These batteries are mainly used in light trucks, cars, and other light vehicles.

They can also provide power for pumps, lights, and winches. The normal size of this category of battery is 230 x 179 x 196 mm. Most batteries in this group have their positive terminal positioned to the left.

With the battery supplying 44 to 60 Ah, you can expect a CCA of 620 to 760 amps and an MCA of 770 to 910 amps. The Group 75 battery is made with AGM technology for increased vibration resistance. When you need a reliable battery that provides a high amount of power, group 75 is an ideal choice.

Group 78 Batteries

Available as starting and dual-purpose AGM batteries, Group 78 batteries are designed to deliver exceptional starting power. They are mostly used in cars and light trucks but can also be used in light industrial and marine and applications.

These batteries provide 50–70 Ah capacity, 700–900 CCA, and 850–1050 MCA. They feature a long life span, up to three times longer than conventional automotive batteries, making them ideal for stop-and-go traffic conditions and other demanding applications.

Many companies sell batteries with the designation “34/78” since the sizes of groups 34 and 78 are very close.

Group 86 Batteries

Group 86 batteries, similar to Group 85 batteries in terms of size and dimensions, are designed for starting/cranking batteries and, as such, are commonly used in automotive and marine applications. The main difference between Group 86 and Group 85 batteries is the orientation of the battery terminals. Group 86 batteries have their terminals oriented in the same direction, while Group 85 batteries are oriented in opposite directions.

Group 86 batteries are mostly lead-acid batteries, with either wet/flooded cells or AGM cells. Most of these batteries supply 45–55 Ah, with a reserve capacity value of 90-95 minutes. The CCA value is usually 500–750 Amps, while the MCA value is usually 650–800 Amps.
