RS PRO Button Battery, LIR2032, 3.6 V, 20 mm Diameter


Use this lithium-ion button battery from RS PRO to power devices such as LED (light-emitting diode) lamps or flashlights. It's durable and long-lasting as it can be recharged up to 500 times.

The chemical composition of this battery gives it high power, which is combined with low charging consumption to offer maximum efficiency and a high energy output. A low self-discharge rate means the component maintains its stored charge capacity well and takes much longer to drain when you're not using it.

This battery's size makes it ideal for powering small pieces of medical equipment such as hearing aids and pacemakers. It's also a good choice for energising watches, remote controls and calculators. The component is Restriction of Hazardous Substances (RoHS) compliant, meaning it contains only minimal amounts of any harmful substances.
