How to use

Install the cell according to the device manufacturer’s polarity markings, ensuring correct orientation for positive and negative terminals. Use in devices specified for ER14250 or equivalent 1/2 AA lithium cells. Replace the battery when device indicators show low battery or when expected service life is reached. Dispose of the spent cell according to local regulations for lithium batteries and do not attempt to recharge, puncture or incinerate the cell.

Usage recommendations

Store unused batteries in a cool, dry place away from direct sunlight and extreme temperatures. For optimal performance, avoid prolonged exposure to high temperatures and remove the battery from devices that will be stored for long periods. Use genuine compatible cells for smart home sensors to ensure reliable operation and predictable service intervals.
