CR2032 cells used in car fobs are 3-volt lithium coin batteries and are single-use (non-rechargeable).

Listed capacities range from about 210 mAh up to 265 mAh, with common intermediate values such as 220 mAh.

One listing explicitly guarantees up to 10 years of storage life; other listings describe “long life” but do not state a specific storage-duration guarantee.

Warranty terms vary: some listings show a 10 Year Limited Warranty while others list a 6 Month Limited Warranty.

Features mentioned include a non-toxic bitter coating to discourage ingestion, child-resistant or hard-to-open packaging (often requiring scissors), and in some cases a saliva-dye alert that indicates contact with saliva.

The listings mark CR2032 cells as single-use and explicitly not rechargeable.

Listings typically state that the batteries meet or exceed original manufacturer specifications and often list comparable model codes or equivalent part numbers.
