Energizer's Child-Safe Batteries for AirTags: Everything You Need to Know

Coin batteries power many devices, but their small size and shiny appearance can attract young children, leading to serious ingestion risks. Apple’s AirTags, while useful for tracking items, have faced scrutiny over easily opened compartments that pose a danger to kids. In response, Energizer has introduced a new battery design that prioritizes safety without sacrificing performance. Below, we answer key questions about this innovation and the broader issue of battery safety.

What Safety Issue Do AirTags Pose for Children?

AirTags use standard CR2032 coin batteries, which are small, round, and often mistaken for candy by toddlers. The original AirTag battery compartment could be twisted open with relative ease, allowing a child to access the battery. If swallowed, these lithium coin batteries can lodge in the esophagus and cause severe internal burns within just two hours, leading to life-threatening injuries or even death. Safety regulators have repeatedly warned about the risk, urging manufacturers to design child-resistant enclosures. Apple later updated AirTags with a tighter battery compartment, but the underlying danger of the batteries themselves remained.

How Does Energizer's Child-Safe Battery Work?

Energizer's new child-safe CR2032 battery features a bitter coating on the metal casing, specifically a non-toxic bitterant that is revolting to taste. If a child puts the battery in their mouth, the intense bitterness triggers an immediate gag reflex, prompting them to spit it out before swallowing. The coating is applied to the entire outer surface and remains effective even if the battery is removed from the package. Additionally, the battery uses a special seal to prevent leaking, and its performance and lifespan are identical to standard CR2032 batteries. This design adds a layer of passive protection without requiring any changes to the device itself.

Even with Child-Safe Batteries, Are AirTags Still a Risk?

While Energizer's bitter coating reduces the chance of ingestion, it does not eliminate all risks. If a child manages to bypass the unpleasant taste and still swallows the battery, the internal chemical hazard remains. Therefore, the bitter coating is a secondary safety measure. The primary defense should always be preventing access: store AirTags and spare batteries out of reach, ensure AirTag compartments are secure (Apple's updated design is harder to open), and supervise children around small objects. The U.S. Consumer Product Safety Commission continues to recommend that all coin battery compartments be child-resistant, so combining child-safe batteries with a secure device is the most effective approach.

What Other Manufacturers Are Doing About Coin Battery Safety?

Several battery makers have taken steps to improve child safety. Duracell, for example, introduced a bitter coating on some of its coin cells and uses secure packaging with double-blisters that are difficult for small hands to open. The industry has also adopted standards like ANSI C18.1M for testing child-resistant closures on battery compartments. In 2022, a U.S. law known as “Reese’s Law” was enacted, requiring stricter packaging and warning labels for coin batteries. These efforts, combined with Energizer's latest product, reflect a growing recognition that prevention must happen at multiple levels: device design, battery design, and consumer education.

Where Can I Buy Energizer Child-Safe Batteries for My AirTags?

Energizer's child-safe CR2032 batteries are available at major retailers such as Amazon, Walmart, Target, and in-store electronics sections. They come in multi-packs and are clearly labeled with packaging that highlights the child-safe, bitter-coating feature. Prices are comparable to standard Energizer coin cells, typically ranging from $5 to $10 for a 2-pack or 4-pack. When purchasing, look for the “child-guard” or “bitter coating” language on the package. Always check the expiration date and ensure the battery is brand-new to get the full safety benefits. For AirTag users, this small upgrade offers peace of mind without any change in performance.

Should I Replace All My Existing AirTag Batteries with Child-Safe Ones?

If you have children under six years old living in or frequently visiting your home, it is strongly advisable to replace standard CR2032 batteries in all AirTags and other coin-cell devices with child-safe alternatives like Energizer's. Even if your AirTag is in a hard-to-reach location, children are curious and may find it. The cost difference is minimal, and the safety benefit is significant. For households without small children, the risk is lower, but accidents can still happen. Consider replacing batteries in devices that are easily accessible (e.g., keychain AirTags, TV remotes, small toys). Remember to recycle old batteries properly.

What Should I Do If My Child Swallows a Coin Battery?

If you suspect a child has swallowed a coin battery, act immediately: call the Poison Control Center at (800) 222-1222 or go to the nearest emergency room. Do not let the child eat or drink anything, as this may cause the battery to conduct more electrical current. Do not induce vomiting. While waiting for medical help, observe for symptoms like coughing, drooling, gagging, chest pain, or difficulty swallowing – but note that some children show no symptoms at first. X-rays can confirm the battery location. Surgery may be needed to remove the battery and repair internal burns. Quick action is crucial because damage can occur within two hours. Prevention remains the best strategy: always use child-safe batteries and keep coin cells out of reach.
