CR1616 Batteries

CR1616 batteries are compact 3-volt lithium coin cells made for small electronic devices that need dependable, space-saving power. Each battery measures approximately 16 mm in diameter and 1.6 mm in thickness, making its slim profile especially useful in devices with very little room inside the battery compartment. Common applications include car keyless-entry remotes and fobs, digital watches, fitness trackers, calculators, small electronic toys, compact measuring tools, glucose monitors, and other low-drain electronic equipment. A CR1616 battery typically provides a capacity of about 50–55 mAh, although actual performance depends on the device, usage pattern, temperature, and battery age. These batteries are generally non-rechargeable, so they should be replaced with a fresh cell when the device begins to lose power, the display becomes faint, buttons respond inconsistently, or the remote works only at close range. Keeping a spare nearby can be particularly helpful during the cooler months, when a weak remote battery may become more noticeable while you are carrying bags, standing near a locked vehicle, or trying to start your day without delay. A spare can also be a practical addition to a household drawer, travel kit, desk organiser, or small gift for someone who relies on watches, personal trackers, calculators, or other compact electronics.

The most important buying consideration is matching the battery to the device’s required size, voltage, and chemistry. Look for the CR1616 designation in the device manual, on the original battery, or inside the battery compartment before purchasing. Several codes may describe a comparable battery size, including DL1616, ECR1616, and BR1616, but a similar-looking coin cell is not automatically a suitable replacement. Coin batteries can share a diameter while differing in thickness, voltage, performance characteristics, or intended application, and forcing an incorrect size into a compartment may damage the device or make the battery difficult to remove. The positive side is usually marked with a “+” symbol and should be positioned exactly as shown by the device’s contacts. When replacing a cell, wash and dry your hands, work over a clear surface, and avoid touching both sides of the battery unnecessarily. If the compartment uses a retaining clip, slide the battery out carefully rather than bending the contact. A small piece of tape can help keep the old cell secure while you carry it to an appropriate collection point, but tape should never cover the markings needed to identify the battery before disposal. For devices that use a different thickness or capacity, browse the selection of CR1632 Batteries instead of assuming that one coin-cell size can substitute for another.

Proper storage helps preserve spare CR1616 batteries until they are needed. Keep them in their original packaging or in a small case that prevents contact with keys, coins, paper clips, and other metal objects. Store batteries in a cool, dry place away from direct sunlight, heaters, damp areas, and children or pets. Loose coin cells should never be placed together in a pocket, drawer, or bag where they can touch metal items, because a short circuit may cause heat or leakage. These batteries are small enough to be swallowed, and ingestion can cause serious injury, particularly for young children; keep unused and used cells out of reach, and seek urgent medical assistance if one may have been swallowed. Do not recharge, open, crush, puncture, bend, or place a CR1616 battery in a fire. Follow local guidance for used-battery collection rather than placing loose cells in regular household waste. Before closing a device’s battery compartment, check that the cell sits flat, the cover locks securely, and the device operates normally. Buying the correct size in a small quantity can make routine replacements easier, whether you are restoring a watch before a trip, keeping a vehicle remote dependable, maintaining a fitness tracker, or helping a family member get a familiar device working again.
