The faster, easier way to work with standards. For flat cells the diameter code is given as the diameter of a circle circumscribed around the whole cell’s area. Flashlights and Parts WTS: A 2 indicates the basis of positive electrode phase, and could be C, N, M, V or T for cobalt, nickel, manganese, vanadium and titanium respectively.

Charging a battery in 2 – 3 hours is much easier to attend to than having to attend to a 16 hour charge. I try to limit the number of standard charges on low self discharge batteries and try to make sure they go through a discharge cycle prior to the standard charge.

After the package size code sadditional letters may optionally appear. Rechargeable 619511 were introduced in the C18 standard inand lithium types were standardized in You may find similar items within these categories by selecting from the choices below:. The 12th edition of C18 began to be harmonized with the IEC standard. Pretend I am a battery manufacture.

Battery nomenclature – Wikipedia

The engineers figure out the best way to get the most capacity into the battery and everyone agrees. Views Read Edit View history. I don’t like to leave NiMH batteries charging when no-one is home. Early editions of the ANSI standard used a letter iecc to identify the dimensions of the cell.


As a general rule, the slower you charge your batteries, the more complete the charge they will take.

Nickel-cadmium and Nickel-metal hydride batteries follow a similar rule as the system above; [11] [12] especially cylindrical cells designed to be dimensionally interchangeable with primary batteries use the same designation as the primary batteries, the codes for electrochemical systems as below. Retrieved from ” https: I hope this adds to ifc perspective. As the battery charges, the voltage will climb until the battery reaches full charge.

Lecmercury batteries were included in the standard. A multi-section battery two or more voltages from the same package will have a multi-section designation.

We use cookies to make our website easier to use and to better understand your needs. OK, back to the real world. The 6951 and S shape codes are still in use but are not to be used for new battery definitions. From Wikipedia, the free encyclopedia. Lithium-ion batteries have a different rule for naming, which applies both to batteries of multiple cells and single cell.

Capacity is settled on as a measuring metric. The Redline version uec you with a quick and easy way to compare all the changes between this standard and its previous edition.

Other round, flat, and square sizes have been standardized but are used mostly for components of multi-cell batteries. Flat cells, used as components of multi-cell batteries, have an F prefix and a series of numbers to identify sizes.

Once the battery reaches full charge, the voltage will start to come down, even though the charger is 69151 charging it.

BS EN 61951-2:2017

Battery electricity Technical terminology. Already Subscribed to this document. The first IEC standards for battery sizes were issued in Standard battery nomenclature describes portable dry cell batteries that have physical dimensions and electrical characteristics interchangeable between manufacturers. In the ANSI standards were extensively revised and separate safety standards provided. Is the “standard charge” a “measurement only” type of thing, or is it a true and tested good way of charging if time is not an issue?


After Octoberround cells are systematically identified with a number derived from their diameter and height.

IEC System of Conformity Assessment Schemes

These run from A to L omitting F and I and depending on the largest dimension of the battery can either signify 0. A zinc-carbon lantern battery. If the document is revised or amended, you will be notified by email. Sizes given as 4 or more digits indicate the diameter of the battery and the overall height. N oec is the maximum diameter in case of cylindrical cells or thickness prismatic cells in mm. I discuss this with my scientists and we work to develop a standard. The International Electrotechnical Commission IEC was established in France in and co-ordinates development of standards for a wide range of electrical products.

Most batteries ied die – they are tortured to near death, then murdered Modern standards contain both systematic names for cell types that give information on the composition and approximate size of the cells, as well as arbitrary numeric codes for cell size. Consisting of 6 cells in series. Certain cell designations from earlier revisions of the standard have been retained. Worldwide Standards We can source any standard from anywhere in the world.
