FAQ

Will These Fit My Device?

If your device specifies a CR2032 or 3V coin cell, these will fit and provide the correct voltage. Common uses include Apple AirTag, car key fobs, thermometers and small LED lights, but always check the device or owner’s manual for the exact cell type. If you’re unsure, look for the marking CR2032 on the old battery before buying the 4-Count Duracell CR2032 3V Lithium Coin Batteries $3.79 w/ S&S + Free Shipping w/ Prime or on orders over $35 to avoid a mismatch.

Are These Safe Around Kids And Pets?

Duracell applies a non-toxic bitter coating on both sides and ships these in child-secure packaging to reduce the risk of accidental ingestion, which adds a useful safety layer. That said, you should still store batteries out of reach and never leave them loose where children or pets can access them. If a battery is swallowed or you suspect ingestion, contact emergency services or poison control immediately.

Is It Worth Buying This Pack And How Should I Store Them?

At the promotional price and with the convenience of $3.79 via S&S and free shipping with Prime or on orders over $35, grabbing a backup 4-count is practical for trackers and remotes, especially given the 10-year storage guarantee. Keep spares in a cool, dry place, avoid mixing new and old cells in the same device, and recycle used lithium coin cells according to local regulations to minimize risk and environmental impact.
