What do Enen and Din mean on a car battery?
EN and DIN are other battery group classification systems that you will sometimes see in owner’s manuals or when shopping for batteries. If you can’t find the right battery in the listed group, then you can use this car battery size chart to find an equivalent using another battery classification system.
What should I look for in a battery size chart?
They provide the length, width, and height in both inches and millimeters. Before you start researching other characteristics like the cold cranking amp (CCA) rating and terminal position, it's good to start by consulting a battery size chart.
What is the international standard for battery size?
Like in many dimension and size regulations, there’s an international standard, set up by IEC but in Anglo-Saxon countries batteries sizes are detemined in letter (AA, AAA C, D, etc.), while in other countries a combination of a letter and digit (AA, Lr20, 6Lr61) is used. AA Batteries. AAA Batteries. C Batteries.
What are the different battery sizes and types?

What is Din for battery?
DIN stands forDeutschesInstitutfürNormung (German Industrial Standard). DIN batteries are suitable for Continental vehicles and selected Korean makes (E.g. Kia/Hyundai). A Maintenance-Free (MF) battery is also known as a VRLA (valve-regulated lead-acid battery) or sealed battery.
What is my battery group size?
If the battery that originally came with your car is still in it, look for the group size on a label on the battery. The label may be on the top or on the side of the case. Group sizes are typically a two-digit number and may be followed with a letter.
How do you read a battery size?
The group sizes are standardized by the Battery Council International, who provide each battery's dimensions in both inches and millimeters. The group numbers are generally two digits and may be followed by a letter. 24F, for instance, is a common battery size that fits many Honda, Toyota, Nissan, and Acura vehicles.
What does BCI mean on a battery?
The Battery Council InternationalCar and Truck Battery Group Size The Battery Council International (BCI) assigns numbers and letters for each battery group size. Group size is typically based on your vehicle's make, model and engine type.
What do battery group sizes mean?
A battery group size is an industry-standard for car batteries that indicates the actual, physical size for a car battery (height x width x length), as well as the polarity (where the positive and negative battery posts are located on the battery).
What is the difference between a Group 24 and Group 35 battery?
The difference between the two batteries lies in their ability to store energy. The Group 24F battery stores more energy because of its high-capacity rating. On the other hand, the Group 35 battery stores less energy because it is rated at a lower capacity.
What do numbers on batteries mean?
Date Code: Most batteries have a date code, usually a long string of numbers and letters that show when the battery was purchased. One row of one- or two-letter codes indicates the month, the other row of numbers is the last digit of the year.
What does CCA and MCA mean on a battery?
CCA is the cold cranking amp rating which tells you how many amps will be delivered to the engine in cold temperatures. MCA or marine cranking amps is conceptually the same rating, however, the CCA rating is based on amps delivered at 0℉ and the MCA rating is done at 32℉.
What is a 12V AGM battery?
AGM 12 Volt Batteries It is an Absorbent Glass Mat (AGM) technology that is a sealed lead-acid battery type. In AGM 12V battery types, the lead plates sit between fiberglass saturated electrolyte mats. This allows increased efficiency in discharging and recharging.
What is MCA on battery?
Marine Cranking Amps (MCA) The MCA rating method measures battery output at 32oF, not 0oF. A battery's MCA rating will be one-third higher than its CCA rating would be. To compare two batteries when one has an MCA rating and the other has a CCA rating, multiply the CCA rating by 1.3 for the equivalent MCA rating.
Are AGM batteries better?
AGM offers better cycling performance, minimal gassing and acid leakage when compared with conventional lead-acid batteries. The end result of all of the features of AGM technology is superior life performance.
What does RC mean on a battery?
Reserve capacityReserve capacity (RC) - helps to power your vehicle's electrical system if the alternator fails. It identifies how many minutes the battery can supply ample power without falling below the minimum voltage needed to run your vehicle.
Understanding Different Battery Sizes
To understand the different battery sizes, let’s first review a few key concepts:
How Do I Know What Size Battery I Need?
The size of your battery bank depends on how much energy you need to run your appliances; your battery system’s energy capacity should always be greater than your energy demand.
Battery Size Chart
This first table shows the usable energy (in Watt-hours) for 12V LiFePO 4 and Sealed lead-acid (AGM and Gel) batteries, rated for 10Ah, 50Ah, 100Ah, 200Ah, and 300Ah.
Final Thoughts
When it comes to sizing your battery bank, there are different types of batteries and capacities to choose from. Moreover, it can be confusing to determine what battery size you need for your specific needs.
What is the diameter of an AA battery?
Same diameter as AA battery, used in small electronics, including electric shaver. 14.5 × 25.0 (max.) Same diameter as AA battery, used in small electronics, including pulse oximeters, as well as use in some computer models (such as most pre-Intel Macintosh models and some older IBM PC compatibles) as the CMOS battery.
What is the nomenclature of a battery?
The complete nomenclature for a battery specifies size, chemistry, terminal arrangement, and special characteristics. The same physically interchangeable cell size or battery size may have widely different characteristics; physical interchangeability is not the sole factor in substituting a battery.
What is a cell with a nub on the terminal called?
Cylindrical cells typically have a positive terminal nub at one end, and a flat negative terminal at the other. A cell with a nub on the positive terminal is called a button-top, and a cell without a positive nub is called a flat-top. Two different cells of the same nominal size, e.g. two 18650 cells, may have different diameter buttons if made by different manufacturers, and this can lead to incompatibility with devices. Flat-top cells cannot be used in series without modification or soldering into position, because the flat positive terminal of one cell cannot contact with the next cell's negative terminal. Rarely, however, a manufacturer may include tiny bumps on the negative terminal, so flat-tops can be used in series.
How long is a lithium ion battery?
Many are also available with internal protection circuits that can increase their physical length; for example, an 18650 is around 65 mm (2.56 in) long, but may be around 68 mm (2.68 in) long with an internal protection circuit. Some such circuits increase cell diameter instead. The increased dimensions may mean the cell will no longer fit in battery compartments intended for cells without such circuitry.
What is the 60086 number?
The current IEC standards for portable primary (non-rechargeable) batteries bear the 60086 number. The relevant US standards are the ANSI C18 series, which are developed by a committee of the US National Electrical Manufacturers Association (NEMA).
What does the IEC designation number mean?
IEC designation numbers indicate the physical dimensions of the cylindrical cell. Cells less than one centimeter in height are assigned 4-digit numbers, where the first 2 digits are the diameter in millimeters, while the last 2 digits are the height in tenths of millimeters.
What is a PP battery?
The PP ( Power Pack) series was manufactured by Ever Ready in the UK ( Eveready in the US). The series comprised multi-cell carbon-zinc batteries used for portable electronic devices. Most sizes are uncommon today; however, the PP3 size (and to a lesser extent PP8 and PP9, which are used in electric fencing and marine applications respectively) is readily available. The PP4 was cylindrical; all the other types were rectangular. Most had snap terminals as seen on the common PP3 type. These came in two incompatible sizes, as is evident in some of the pictures below, those on larger, mostly older, battery types such as the PP9 being somewhat larger than those on the smaller batteries such as the PP3.
