These round, size CR1225 lithium manganese dioxide button batteries from RS PRO are used to power small items such as watches, calculators and remote controls. They hold a stable voltage throughout their lifespan and are corrosion-resistant for long-lasting and reliable use.
Each small unit has a low self-discharge rate of only 3% per year. This gives them a long shelf life, meaning you can store them unused for extended periods without risking them losing charge. For best results, you should store each battery in its packaging and keep it away from heat sources and sunlight.
The RS PRO range of lithium coin batteries has passed UL (Underwriter Laboratories) testing, so each battery is certified as safe to use. The batteries are sold in packs of five and are RoHS (Restriction of Hazardous Substances) compliant, meaning they contain minimal levels of harmful materials.
