History of the ANSI standard
Standardization inside the United States arose within 1919, as soon as the National Bureau of Standards printed qualified sample methods and standard amounts of cells. charity American measures were rekindled some instants during the waging decades, as fresh scales of units were arranged and new chemistry developed, embracing chloride, alkaline, mercury and rechargeable types. The former American Standards Association (predecessor towards ANSI) benchmark C18 surfaced within 1928. It noted cell scales enlisting a communication code, about inside manoeuvre of height from meagre (A) towards inflamed types. The completely numerical collection was the 6-inch high "No. 6" cell. The 1934 version of the C18 benchmark broader the nomenclature scheme within the direction of embrace succession and alike arrays of cells. In 1954 mercury electric-powered storage storage electric batteries were draped within the standard. The 1959 publication defined classes proper for exercise with transistor radios. In 1967 NEMA took afresh accountability for propagation from the National Bureau of Standards. The 12th version of C18 started towards be harmonized with the IEC standard. Rechargeable batteries were surrendered inside the C18 criterion within 1984, and lithium multiplies were normalized within 1991.
In 1999 the ANSI benchmarks were considerably rejuvenated and recognise security benchmarks provided. The prevailing version of the ANSI benchmarks designates scales with an random number, prefixed with a communication within the direction of designate profile and a suffix communication or message inside the direction of distinuish unlike chemistry or terminals or else features.
The IEC was rated inside 1906 and co-ordinates increases of measures for a thick collection of electrotechnical products. The IEC vindicates pair committees, TC21 located within 1933 for rechargeable batteries, and TC 35 installed within 1948 for first batteries, within the direction of devises standards. charities In 1992 the prevailing assortment scheme was adopted. Battery forms are designated with a letter/number series displaying diagram of cells, cell chemistry, cell shape, dimensions, and extraordinary characteristics. Certain cell designations from initially modifications of the benchmark own been retained. charities The former IEC benchmarks for electric storage electric storage battery scales were handed out within 1957. benevolent heritage Since 1992, International benchmark IEC 60086 recounts an alphanumeric encrypting system for batteries. charities British aspect 397 for initial batteries was extracted and returned via the IEC benchmark inside 1996.
Examples of the IEC nomenclature are batteries coded R20, 4LR25-2, CR17345, and 6F22. The alphabet and mathematics inside the ciphers suggest the figure of cells, cell chemistry, shape, dimensions, and the diagram of sided channels within the built battery. A multi-section battery (two or several voltages from the replicate package) shall possess a multi-section designation.

Height in 0.1 mm
A lone carbon-zinc flashlight battery, height 20 which is counterparts in the direction of D, or ANSI "13" size
An alkaline lantern battery, geared higher of two lined higher rows of 4 around object height 25 units in series
A single-cell right through lithium battery, 17 mm dia via 34.5 mm high,
9 Volt transistor radio battery ready of 6 flat height 22 carbon-zinc cells
The previous letter diagnoses the chemical composition of the battery, which in assistance implies a nominal voltage. Certain rechargeable battery systems, ordinarily practised in scales similar with first batteries, also possess criterion symbols.
Italics present a chemical scheme dubious to be discovered in client or general-purpose batteries, or withdrew from the newest standard.
R Round, (coin, button or cylindrical)
F Flat (layer built)
S Square (or rectangular or prismatic)
Certain sizes, bestowed via one or pair index finger numbers, depict yardstick elevation ciphers from previously editions of the standard. Sizes bestowed as 4 or 5 appendages show the diameter of the battery and the overall height. The figures in the code correlate with the cell dimensions: the (truncated) diameter, in millimetres chased via the height, in tenths of a millimetre.
Size codes for round object batteries, bestowed by a one or two finger figure tailing the R involve :
Size computer encrypting for circle batteries
Round button batteries also bear two-digit elevation computer coding such as R44, perceive the button battery desk for typical dimensions. Other round, flat, and square straightens possess been normalized but are accustomed largely for fractions of multi-cell batteries.
The IEC yardstick listings the consecutive diameter and amount codes for coin cells:
Coin cell diameter and height codes
After the packet amount code, added alphabet may optionally arise in the breed designation to indicate the electrolyte used:
S: sodium hydroxide electrolyte
P: potassium hydroxide electrolyte
no letter: organic electrolyte
Terminal styles and process floors may also be designated with a C, P, S, X, Y, CF, HH, or HB or other letter suffixes. Rechargeable selections may own a suffix L, M, or H to designate low, intermediate or high burst rating designs. An appended letter "W" states that this battery obeys with all the qualifications of the IEC 60086-3 yardstick for gaze batteries.
Previous editions of the ANSI yardstick exercised a letter code to detect the sized of the cell. Since at the instant there were basically carbon-zinc cells, not no matter what suffix alphabet or other notation was required. The system was introduced in the 1924 edition of the standard, with letters A across J granted commonly in order of lifting cell volume, for units typically manufactured at that time. By 1934, the system had been prolonged and reviewed and already had 17 sizes coming to from NS at 7/16 inch diameter by 3/4 inch height, over amount J at 1 3/4 inches diameter by 5/78 inches high, to the foremost principle cell which booked its old designation of No. 6 and which was 2 1/2 inches in diameter and 6 inches high.
Size and form codes
The realtime edition of the religion includes a numerical code to seem the cell size. Common round cell sizes are:
ANSI premier cell dimensions and counterparts amount designations
Since these IEC and ANSI battery ideals own been harmonized, for example, an R20 cell will possessed the equivalent sized as an ANSI 13 cell.
Flat cells, employed as elements of multi-cell batteries, owned an F prefix and a sequence of figures to acknowledge sizes. Coin cubicles were ascribed amount codes in the 5000 range.
Secondary units employing webs H and K (nickel-metal hydride and nickel-iron sulfide) owned a demarcate series of capacity codes, but the cells are dimensionally interchangeable with original cells.
System and process suffix letters
The electrochemical system and procedure knowledge is given in suffix letters.
