CR2016 Battery

The CR2016 is a 3.0V lithium button cell in the CR series, with a nominal capacity of 75 mAh and a size of 20.0 x 1.6 mm. It is a small, flat, single-use cell for compact devices: watches, calculators, remote controls, car keys, medical monitors, small sensors and backup memory circuits. The button cell line is stated to have a shelf life of more than 5 years, low self-discharge, and RoHS-compliant mercury-free construction, and cells are available with tabs or leads for OEM assembly.

Button cells are chosen where space is the binding constraint. A device housing that accepts a 20 mm diameter cell still needs the right thickness: a CR2032 at 3.2 mm thick is not interchangeable with a CR2025 at 2.5 mm or a CR2016 at 1.6 mm, even though all three share the same diameter. That is why this site lists diameter and thickness for every button cell model, and why the button cell size guide explains how the numbering works. Getting the size right matters more than squeezing out extra capacity, because a cell that does not fit the holder cannot be used at all.

Three characteristics define the button cell line. First, compactness: diameters from 9.5 mm to 30 mm across the full CR range, with thicknesses from 1.6 mm to 7.7 mm, cover a wide span of small devices. Second, shelf life: more than 5 years at category level, so a device stored before sale still works when it reaches the buyer. Third, assembly options: tabs or leads for OEM use allow the cell to be soldered or clipped into a product during manufacturing rather than fitted by the end user. The model-specific figures in the table above are the values that apply to this model.

Important note from the source catalogue table: capacity, size and weight for button cells are stated to be subject to the final datasheet, and must be confirmed before mass production. This page preserves that note and does not present table values as guaranteed values. When ordering, confirm the model number, the thickness, whether tabs or leads are required, and the quantity. Minimum order value is USD $500, according to the company FAQ, and samples are available. Lead time is confirmed per order. Certificates are available upon request.

The button cell range around this model covers sizes from CR927 at 9.5 by 2.7 mm up to CR3032 at 30.0 by 3.2 mm, with capacities from 30 mAh to 500 mAh in the source table. That span covers watches, calculators, remote controls, car keys, medical monitors, small sensors and backup memory circuits, and the same selection rule applies to all of them: match the full model number, including thickness, because a cell of the right diameter but the wrong thickness will not fit or will not contact properly. Cells are available with tabs or leads for OEM assembly, which allows the cell to be soldered or clipped into a product during manufacturing rather than fitted by the end user. For an OEM order, the tab or lead configuration should be specified alongside the model number.

Storage and handling for button cells follow the same rules as for other primary lithium cells, with one extra caution that comes from their size: small cells are easily lost, mixed with other sizes, or swallowed by small children, so they should be kept in labelled packaging, out of reach of children, and never stored loose with metal objects. Store cells cool and dry, in packaging that prevents terminals from touching. Cells that are swollen, leaking or physically damaged should not be installed, and should be disposed of through the proper channel for lithium cells. For transport, UN38.3 test documentation applies to the cell design, and shipping arrangements are confirmed per order.
