Panasonic CR1616 3.0V lithium coin cell 4-pack

This four-pack supplies 3.0 V lithium coin cells rated at 55 mAh each. They suit small electronic devices such as car key fobs, calculators, watches, fitness appliances, toys and medical equipment. The cells are manufactured in Indonesia and finished in a U.S. packaging facility.

Operating temperature range and shelf life

Reliable operation is specified from 14 °F to 140 °F. Unused cells retain usable charge for up to eight years when stored properly. No active cooling or power management is required for these primary cells in normal use.

Questions about this item

How do I install the CR1616 in a key fob without damaging the contacts?

Slide the cell in with the marked positive side facing up, matching the holder's polarity symbol. The step people miss is cleaning the contacts first — residue from the old cell can block the 3.0 V supply.

When will these four cells need replacing in a device used daily?

Each CR1616 holds 55 mAh. In a typical key fob that draws microamps, one cell lasts several years. The pack gives you three spares, so replacement depends on the device's actual drain, not a fixed calendar date.

What is the first limit I will hit if the device runs continuously in a hot car?

The rated operating range tops out at 140 °F. Above that temperature the internal chemistry degrades rapidly, so sustained heat is the first limit — not the 8-year shelf life or the 55 mAh capacity.
