No Sew CR2032 3V Lithium Coin Battery 6-Pack 230mAh

Everyday power for small devices

This six-pack supplies 3 V lithium coin cells rated at 230 mAh each. They fit watches, calculators, remote controls, thermometers, kitchen scales and compatible door sensors from brands such as TP-Link and Aqara. The mercury-free chemistry delivers a low self-discharge rate below three percent annually at room temperature. A ten-year shelf life is quoted when stored at 20±2 °C and 55±20 % relative humidity.

Temperature and chemistry limits

The cells operate from -20 °C to +60 °C, so they remain functional in cold garages or warm indoor locations. They are non-rechargeable; attempting to charge them can cause leakage or rupture. High-purity lithium construction provides high energy density, but the chemistry is not suited for high-drain applications that exceed the rated capacity. Self-discharge stays minimal under recommended storage conditions.

Compact build and simple replacement

Each cell measures 20 mm by 3.2 mm and weighs 2.8 g, matching the standard CR2032 footprint used in countless small electronics. The flat button-top design allows quick swaps without tools in key fobs, sensors and toys. A six-pack format keeps spares on hand for multiple devices around the home. Mercury-free materials meet common environmental restrictions for household batteries.
