Cr1620 battery

The CR1620 is a 3-volt lithium coin cell used in small devices such as watches and remotes. When selecting, verify your device’s required size and voltage in its manual or back panel. Consider non-rechargeable types, since these cells are designed for single-use power delivery. Typical capacity for CR1620 variants sits around 75–80 mAh, though brands may specify slightly different values.

The 3V rating indicates the electrical pressure available to run small electronics, while capacity (measured in mAh) determines how long the device will function before replacement. In this range, several options describe solid shelf life and stable performance, with some models noting long-term capacity retention (up to 90% after about 10 years). Choosing the right brand and capacity helps devices like watches or remotes stay reliable for longer between changes.

CR1620 cells are commonly found in watches, remote controls, small electronic gadgets, and certain medical or measuring devices. Look for these specific use cases when shopping, as the 3V lithium coin cell size is compact enough to fit tight compartments while delivering steady, dependable power for daily tasks.

Keep spare cells in their original packaging or a dry, cool place away from metal objects to avoid short circuits. When replacing, use the correct orientation as indicated on the device’s battery compartment, and avoid mixing old and new cells. Do not expose batteries to high heat or direct sunlight, which can degrade performance and shorten shelf life.

First, recheck that the battery is the correct type and oriented correctly. If power still isn’t restored, inspect the battery contact points for corrosion or residue and gently clean with a soft cloth. If issues persist, confirm that the device requires a CR1620 and that the fit and fitment are suitable for ongoing operation.

Multiple trusted brands are available, including Panasonic, Camelion, Murata, and Renata, each offering 3V CR1620 lithium coin cells. Brand choice depends on device compatibility, availability, and your preference for shelf-life reliability. For most everyday devices, any reputable brand that matches 3V and the CR1620 size will perform reliably, so choose a trusted option and store extras safely for future use.
