CR1632 battery equivalent

CR1632 is a lithium manganese dioxide coin cell, 16.00 mm across and 3.20 mm tall, rated 3.0 V. Energizer and Panasonic agree on all of that. They do not agree on capacity: Energizer’s datasheet says 130 mAh, Panasonic’s catalogue says 140 mAh.

Why two capacity figures

The two numbers come from different documents, and each is the maker’s own rating. Energizer’s sheet gives 130 mAh to 2.0 V under a 15 kΩ load, and its test table lists 684 hours of continuous drain at 0.19 mA down to 2.0 V. Panasonic’s table lists 140 mAh as nominal capacity and does not give a load on that row. We show both and do not average them; the box below has the sources.

Codes on the sheets

Energizer’s CR2450 sheet prints an ANSI / NEDA name next to the IEC one. Its CR1632 sheet does not: the only name on it is CR1632, so this page has no second code to list. DL1632 is also searched for, but it is not printed on any maker sheet or cross-reference page this site cites, and we hold no Duracell or Renata CR1632 sheet, so we don’t list it.

Not a CR2016

The CR1632 is 16 mm across and the CR2016 is 20 mm, so the datasheets give no basis for swapping one for the other:

Rated capacity

Sources disagree

Each maker rates capacity under its own test load and cut-off voltage, so the figures below aren’t measured the same way.
