Duracell CR2032 3V Lithium Coin Batteries (8 Pack) with Baby Secure Technology for AirTags & key fobs
Product description
The essentials
If you’ve ever swapped a coin-cell battery and realised the device feels a bit “off” again sooner than expected, you’ll know why people obsess over battery life and reliability. These Duracell CR2032 lithium coin batteries are sold as an 8 pack and are positioned for everyday low-drain electronics such as Apple AirTags, key fobs, and a range of home, fitness and medical accessories.
On paper, the story here isn’t just about longevity. Duracell also highlights its “Baby Secure” approach: a bitter taste ring designed to discourage swallowing, plus packaging intended to be harder for children to open without scissors. It’s the sort of extra safety thinking that can matter in households with toddlers, even if you’re usually careful with battery storage.
What they’re for
These CR2032 3V coin cells are recommended for use in Apple AirTags, and they can also be used in other devices such as key fobs, home devices, fitness and medical accessories. That makes this pack useful if you don’t want to keep buying single batteries every time a gadget starts acting up.
A practical example: if you have a key fob that warns you before it fully dies, having spares in a drawer means you can swap the cell quickly rather than waiting for a delivery. With devices like trackers and sensors that live around daily life, having the right battery format on hand reduces hassle.
What stands out in use (and what might disappoint)
The most distinctive angle is the combination of battery performance claims and safety features.
Duracell states “up to 70% extra life” compared with a minimum average duration based on electronic key IEC standard testing for 2032 lithium coin batteries. It also notes that results can vary by device and usage patterns—so this isn’t a guarantee that every gadget will feel dramatically longer-lasting in real life.
The other big talking point is the bitter taste ring plus baby secure packaging. It may not make the battery “child-proof” in every sense, but it’s clearly aimed at reducing risk if a child gets hold of one.
Quick overview of the key buying considerations
Before you buy a pack like this, it helps to check three things:
- Device battery type: you specifically need CR2032 coin batteries, and your device should be compatible with that format.
- Household needs: if you have young children, the bitter taste ring and double blister packaging are the main reasons people pick this style over more basic coin cells.
- Expectations on lifespan: “up to” performance claims depend on how your device uses the battery.
Also worth noting: storage is covered by a “10 years in storage guaranteed” claim when kept unused in its packaging, which is useful if you’re buying a multipack to top up a household stash.
Key points on the safety design
Duracell describes a non-toxic bitter taste ring-shaped layer with Bitrex applied on both sides of the cell, intended to discourage swallowing by babies and toddlers. There’s also “baby secure packaging” using a double blister that is difficult to open without scissors.
If you’re buying batteries mainly for long-term storage, the packaging and storage claim can be a plus. If you’re buying for immediate use only, the safety details still matter if batteries are likely to be handled around the home.
Pros
- CR2032 3V lithium coin batteries in a convenient 8 pack
- Recommended for Apple AirTags, plus broader use in key fobs and various household and accessory devices
- Claims up to 70% extra life, with an explanation that results may vary
- Baby Secure Technology (bitter taste ring) and baby secure packaging aimed at reducing swallowing risk
- 10 years in storage guaranteed while unused in packaging
Final verdict
Is it worth it?
Worth considering if you want a reliable CR2032 option for common small devices (especially AirTags and key fobs) and you also care about extra safety cues for homes with young children. The 8 pack suits people who like to keep spares ready rather than reordering whenever a gadget gives a low-battery signal.
It might not be the best choice if you only need a single replacement battery and don’t want to store extras, or if you’re expecting identical “extra life” results across every device. Coin cells are heavily dependent on the device’s power draw and how often it activates, so the headline life claim is not a straight guarantee.
