Lithium manganese button batteries are known for their low self-discharge rate, which means that the battery can maintain its charge even when not used for a long time. This is especially important for spare remote controls that are not often used, ensuring that they can be used immediately when needed. As the leading supplier of CR series lithium manganese button batteries in the European market, Power Glory is well aware of the importance of low self-discharge rate to user experience, so our products are particularly outstanding in this performance.
