The good news: Your AirTags won’t need a battery replacement for an entire year as they were just released and are said to have a year-long battery life.
The bad news: When the time does come to replace your AirTag battery, if you get the batteries Apple is warning about WITHOUT the safety bitter coating, your baby might enjoy it and risk swallowing it whole.
If your baby is more important (SPOILER: mine’s not) and you purchase the bitterant coated batteries that are safer for little Jr., your baby will be safe but then your AirTags might not work.
Me personally? I say “fu*k that baby” because momma needs her AirTags. What? That weak-necked baby can’t even hold its head up yet, let alone do any cool tricks like locate my lost devices.
“CR2032 batteries with bitterant coatings might not work with AirTag or other battery-powered products, depending on the alignment of the coating in relation to the battery contacts.”– Apple support page
According to Duracell, hundreds of lithium coin batteries are accidentally swallowed by children every year. Left untreated, an ingested lithium coin battery can cause a harmful chemical reaction in as little as two hours. Their non-toxic bitter coating reacts with saliva to then deter swallowing.
Apple’s support page goes on to explain how the alignment of the coating in relation to the battery contact is the issue. To ensure the battery will work, AirTag users should buy replacement CR2032 batteries that do not have any kind of coating.
