5Pcs/Set Sony Coin Cell Battery CR2016/CR2025/CR2032 3V Lithium Replaces

This 5-piece set of Sony CR2016, CR2025, and CR2032 coin cell batteries delivers dependable 3-volt lithium power for a wide range of everyday electronics. Whether you need to revive a key fob, keep a digital scale running, or power a small medical device, these button cells offer a compact and stable energy source that fits where standard batteries cannot. With three common sizes in one package, you always have the right battery on hand when a device stops working.

Engineered with genuine Sony lithium chemistry, each cell provides consistent voltage output, minimal self-discharge, and reliable performance in temperatures from −20°C to +60°C. The built-in manganese dioxide cathode and organic electrolyte system ensure safe, leak-resistant operation over the product's 7-year shelf life. Unlike generic alternatives, Sony batteries meet strict quality standards for capacity retention and internal resistance, making them a trusted choice for both new builds and replacements.

Installation is straightforward—simply remove the old battery, clean the contacts, and press in the new one. The set includes one CR2016 (160mAh), one CR2025 (170mAh), and three CR2032 (220mAh each) batteries, giving you flexibility across devices. Always verify the required size before inserting, and store unused cells in a cool, dry place to maximize their ready-to-use lifespan.

These coin cells fit thousands of household, automotive, and medical devices. Below are the most common use cases grouped by application—always confirm your device’s battery size before installation.

Follow these simple steps to safely replace your old coin cell and get your device running again.

1. 1 Identify the correct battery size — Open the battery compartment and note the printed model (CR2016, CR2025, or CR2032). Match it to the appropriate battery from this set; using the wrong thickness can damage the contacts.
2. 2 Power off the device — If possible, turn off the device or remove any other power source to prevent short circuits during battery handling.
3. 3 Clean the battery contacts — Use a dry cotton swab or soft cloth to gently wipe away any dust, oxidation, or residue from the spring terminals. Clean contacts ensure optimal electrical conductivity.
4. 4 Insert the new battery — Place the battery with the positive (+) side facing up (usually the side with the printed model number). Press gently until it snaps into place—never force it.
5. 5 Close the compartment and test — Replace the cover or door securely, then power on the device. Confirm functionality (e.g., press a button on a remote, check the watch display).
6. 6 Store spare batteries correctly — Keep unused cells in a cool, dry place away from direct sunlight and metal objects. The original blister pack or a non-conductive container works perfectly.
