Where can I buy, store and dispose of air tag batteries to always have a spare? Apple says the battery in an AirTag is a standard CR2032 coin cell that is designed to last for about a year if it's used normally. Spares can be easily found because it is a common size, but where the question? It is recommended to choose a trusted dealer as the cells may be shortened in their lifespan due to old or faulty cells. Make sure that the CR2032 is on the packaging as the CR2025 is a thinner coin cell and can look similar.A few coin batteries also have a coating on the battery that has a bad taste and may not allow the tags to contact the battery properly. When a battery seems to be dead, test it with another brand tag battery before assuming that the newly bought tag battery is faulty. Save an extra one at home in case your iPhone beeps when the battery level is low from the Find My application.Storage needs care. Spare batteries and loose tags are dangerous if swallowed, and must be stored in their original packaging away from small children and pets. Keep loose cells away from metal objects such as keys or coins they can short out the cells. Keep them in a cool and dry place, they don't keep for long when exposed to heat and humidity.When replacing an air tag battery, please dispose of the used battery in an environmentally friendly way. Do not put it in the household garbage as used cells can still be charged and are a fire hazard. Drop it off at a battery collection centre, and if recommended by a local scheme, tape over the terminals before disposing of the battery.
