421: 1675:, England, with a population of 2,700,000, two children between 12 months and six years old died, and five suffered life-changing injuries, in the 18 months leading up to October 2014. In the United States, on average, over 3,000 pediatric ingestions of button batteries are reported annually. The proportion of major and fatal outcomes is increasing. Coin cells of diameter 20 mm or greater cause the most serious injuries, even if expended and intact. In Auckland, New Zealand as of 2018 there are about 20 cases per year requiring hospitalization. 1114: 1645: 1590: 393:(e.g., 1.3 V) to operate correctly, a silver cell with a flat discharge characteristic will give much longer service than an alkaline cell—even if it has the same specified capacity in mAh to an end-point of 0.9 V. If a device seems to "eat up" batteries after the original supplied by the manufacturer is replaced, it may be useful to check the device's requirements and the replacement battery's characteristics.

The same site lists rechargeable cells with various chemistries, in the same sizes and options as disposable batteries of the same size code and hence mechanically interchangeable, though carrying risks of malfunctioning and damage. 218:. Devices using button cells are usually designed around a cell giving a long service life, typically well over a year in continuous use in a wristwatch. Most button cells have low self-discharge, holding their charge for a long time if not used. Relatively high-power devices such as hearing aids may use a 1652:
Button cells are attractive to small children; they may put them in their mouth and swallow them. The ingested battery can cause significant damage to internal organs. The battery reacts with bodily fluids, such as mucus or saliva, creating a circuit which can release an alkali that is strong enough

Rechargeable batteries typically have the same dimension-based numeric code with different letters; thus CR2032 is a disposable battery while ML2032, VL2032 and LIR2032 are rechargeables that fit in the same holder if not fitted with solder tags. It is mechanically possible, though hazardous, to fit

For types with stable voltage falling precipitously at end-of-life (cliff-top voltage-versus-time graph), the end-voltage is the value at the "cliff-edge", after which the voltage drops extremely rapidly. For types which lose voltage gradually (slope graph, no cliff-edge), the end-point is the
