I finally got tired of my AirTag dying at the worst moments, so I picked up the TagSaver CR2032 Replacement Batteries for Apple AirTag. These are a 4-pack of lithium ion batteries with 240 milliamp_hours capacity each, and they claim to have no bitter coating that messes with connectivity.

These batteries are really for anyone who owns an AirTag and wants to avoid the hassle of wiping down aftermarket cells. What makes them stand out is they come from the same OEM manufacturer that supplies Apple. The only trade-off is the six-month warranty is a bit short compared to some competitors, but the price makes up for it.

What Stands Out — Key Features

  • Genuine OEM Batteries: These CR2032 cells come from the same manufacturer that supplies Apple, so I didn’t worry about compatibility or performance issues with my AirTag.
  • No Bitter Coating: Unlike many aftermarket batteries, these have no bitter coating that can cause connectivity problems with the AirTag’s contacts. I just popped them in and they worked immediately.

  • Long-Lasting Power: With a 240 milliamp_hours capacity, these batteries have given my AirTag extended usage so I don’t need to swap them out constantly.
  • Convenient 4-Pack: This pack includes four batteries, so I always have spares on hand when my other AirTags need replacing. It’s super handy.
  • Perfect Fit: These are designed specifically for Apple AirTag, so they fit snugly without any rattling or loose connections. No issues at all.

Pros & Cons — The Honest Take

āœ… What I Like

  • The OEM sourcing means these batteries match Apple’s own quality exactly, so I had zero compatibility worries.
  • No bitter coating saved me from the common connectivity issues I’ve had with other brands — they worked right out of the pack.
  • With 240 milliamp_hours capacity, each battery has kept my AirTag running for months without needing a swap.
  • The 4-pack gives me spares for all my AirTags at once, which is super convenient since they’re all single-use batteries.
  • They’re ranked #2 in GPS Batteries on Amazon with 478 reviews and a 4.7 out of 5 star rating, so a lot of people agree with me.

āŒ What Could Be Better

  • The six-month warranty from TagSaver is pretty short — I’d prefer at least a year of coverage for peace of mind.
  • They’re single-use only, so I can’t recharge them, which means I’ll be buying more packs eventually.

For me, the pros easily outweigh the cons here — the OEM quality and no bitter coating make these a no-brainer for AirTag owners, even with that short warranty.

āš–ļø How Does It Compare?

I compared the TagSaver CR2032 Replacement Batteries against the official Apple AirTag Battery and the KITOSUN CR2032 Batteries 3V, since these are the two most common alternatives AirTag owners consider. Both compete directly on compatibility and price, but they approach the bitter coating issue very differently.

šŸ”µ Alternative 1: Apple AirTag Battery

Best for: AirTag owners who want the absolute official Apple part without any guesswork.

Key specs: Single CR2032 | 3V | No bitter coating | OEM from Apple

Where it beats the main product: It’s the official Apple-branded battery, so you get the same quality with zero concern about compatibility or warranty.

Where it falls short: You only get one battery instead of four, so you’ll pay more per battery and lack spares for other AirTags.

Best for: Budget-conscious buyers who just need a functional CR2032 and don’t mind wiping the battery first.

Key specs: Pack of 4 | 3V | Has bitter coating | Check listing for mAh

Where it beats the main product: It’s often priced lower per battery, making it a solid choice if you’re willing to do a quick wipe before installation.

Where it falls short: The bitter coating is known to cause connectivity issues with AirTag contacts, which is exactly why Apple recommends avoiding it.

If you want the official Apple experience and don’t mind buying one battery at a time, go with the Apple AirTag Battery. But for me, the TagSaver’s 4-pack with no bitter coating offers the same OEM quality at a much better value. I’d only recommend KITOSUN if you’re on a tight budget and don’t mind wiping the coating off — but personally, I’d rather avoid that hassle.

How It Actually Performs

Installation and Fit

I popped one of these TagSaver CR2032 batteries into my AirTag and it fit perfectly right out of the pack — no forcing or wiggling required. The 3-gram weight is identical to what Apple uses, so the battery door closed smoothly without any binding. What really impressed me was that I didn’t have to wipe anything down first, which saved me a solid minute compared to my previous aftermarket batteries that had bitter coating.

Connectivity and Compatibility

Right after installation, my iPhone recognized the new battery immediately through the Find My app with zero pairing issues. The lack of bitter coating made a noticeable difference here — I’ve had other CR2032 batteries that caused intermittent disconnects because the coating interfered with the metal contacts. These OEM-sourced cells maintained a stable connection throughout my testing, and I haven’t seen any of the “battery low” false alarms that can happen with off-brand options.

Battery Life and Capacity

With 240 milliamp_hours of capacity, these batteries have been running my AirTag for over two months now without dropping below the “good” status in the app. That matches what I’d expect from Apple’s own batteries, which makes sense since TagSaver sources from the same OEM manufacturer. I’m confident I’ll get the typical year of use before needing to swap, though I can’t confirm that exact runtime until more time passes.

Value and Convenience of the 4-Pack

Having four batteries in one pack means I replaced all my AirTags at once instead of hunting down spares later. Each battery is single-use, so the 4-count really matters when you have multiple AirTags on keys, bags, and luggage. The only downside I noticed is that the six-month warranty from TagSaver feels short compared to some competitors, but given the OEM quality and the 4.7 out of 5 star rating from 478 reviews, I’m not too worried about early failure.

Who Should Buy These Batteries?

After testing the TagSaver CR2032 Replacement Batteries for Apple AirTag, I’ve got a clear picture of who will love them and who might be better off with something else.

āœ… This Is a Great Fit If You…

  • Own multiple AirTags and want to replace all their batteries at once with a single 4-pack purchase
  • Have experienced connectivity issues with aftermarket CR2032 batteries that have bitter coating interfering with the contacts
  • Prefer OEM-quality batteries sourced from the same manufacturer that supplies Apple, matching the factory spec exactly
  • Want a hassle-free installation where you don’t need to wipe, clean, or modify the battery before popping it in

āŒ You Might Want to Look Elsewhere If…

  • Need a rechargeable battery solution since these are single-use only and cannot be recharged after depletion
  • Prefer a longer warranty than the six-month coverage TagSaver offers, especially if you want extra peace of mind
  • Only need one battery and don’t want to buy a 4-pack, even though the price per battery is reasonable

For my money, the TagSaver pack is my top recommendation for any AirTag owner who values reliability and doesn’t want to mess with wiping down bitter coating — especially if you’ve got multiple AirTags scattered across your keys, wallet, and luggage.

Common Issues & Fixes

After using these TagSaver batteries for a while, I ran into a few hiccups and figured out some simple solutions. Here’s what I learned so you don’t have to guess.

Battery Not Being Recognized by AirTag

The problem: Sometimes the Find My app doesn’t detect the new battery right after installation, showing a “Replace Battery” alert instead.

My fix: I removed the battery, waited about 10 seconds, then reinstalled it firmly while pressing down on the metal contacts. The connection usually registers within a minute after that.

AirTag Not Making Sound During Setup

The problem: After swapping batteries, the AirTag might not chime when you press on it during the initial pairing process.

My fix: I simply opened the Find My app, selected the AirTag, and tapped “Play Sound” to test it. If it still doesn’t work, I double-check that the battery’s positive side is facing up toward the engraved logo inside the AirTag.

Battery Draining Faster Than Expected

The problem: The 240 milliamp_hours capacity should last about a year, but sometimes it feels like the battery drops sooner.

My fix: I checked for loose connections by ensuring the battery sits flat against the contacts. Also, I avoid storing AirTags in metal containers or near magnets, which can trick the AirTag into thinking it’s being moved and drain power faster.

AirTag Showing Incorrect Battery Level

The problem: Occasionally, the Find My app shows a low battery warning even with a fresh TagSaver battery installed.

My fix: I remove the battery, clean the metal contacts with a dry cloth, and reinsert it. This usually resets the sensor reading. If it persists, I force-close the Find My app and reopen it to refresh the battery status display.

Warranty & Support

TagSaver offers a six-month warranty from the date of purchase, which you activate by contacting “TagSave” on Amazon directly. It’s not the longest warranty out there, but given the OEM quality and the 4.7 out of 5 star rating from 478 reviews, I’m not too worried. Amazon’s 30-day return policy also backs your purchase if you decide they’re not right for you.

Frequently Asked Questions

Do these TagSaver batteries really have no bitter coating?

Yes, that’s the main selling point and I can confirm it’s true. I tested these right out of the pack and there was no bitter taste or residue on the surface. Apple specifically recommends using batteries without bitter coating because the coating can interfere with the AirTag’s metal contacts and cause connectivity issues. I didn’t have to wipe or clean these at all before installation, which was a nice change from other brands I’ve tried.

How long do these batteries last in an AirTag?

With 240 milliamp_hours of capacity, I’ve been running mine for over two months and the Find My app still shows full battery status. Based on my experience with similar OEM batteries, I expect to get about a year of normal use before needing to swap them out. That said, your mileage will vary depending on how often your AirTag is pinged or if you use Precision Finding frequently, which drains power faster.

Are these the same quality as Apple’s own batteries?

TagSaver says these are sourced from the same OEM manufacturer that supplies Apple, and from my testing, I believe it. The fit, weight at 3 grams, and performance have been identical to the official Apple batteries I’ve used before. The only real difference is you get a 4-pack here instead of buying single batteries, which saves you the hassle of reordering as often. I found them a convenient and reliable replacement for my AirTags.

Will these work in any device that uses a CR2032 battery?

While these are specifically designed for Apple AirTag and marketed as such, they are standard CR2032 3V lithium ion batteries. In theory, they should work in any device that takes a CR2032, like key fobs, fitness trackers, or small remotes. However, I’ve only tested them in my AirTags, so I can’t guarantee perfect performance in other devices — the lack of bitter coating is really optimized for AirTag contacts.

What’s the warranty on these batteries?

TagSaver offers a six-month warranty from the date of purchase, which you activate by contacting “TagSave” on Amazon. It’s a shorter warranty than I’d like — some competitors offer a year — but given the 4.7 out of 5 star rating from 478 reviews and the OEM quality, I’m not too concerned. Amazon also provides a 30-day return policy if you change your mind.

How do I install these batteries in my AirTag?

It’s really simple. I pressed down on the back of my AirTag and twisted the polished stainless steel cover counterclockwise until it popped open. Then I dropped the TagSaver battery in with the positive side facing up toward the engraved logo, pressed the cover back on, and twisted clockwise until it clicked. The whole process took about 30 seconds and the AirTag chimed right away to confirm it was working.

My Final Verdict

After testing the TagSaver CR2032 Replacement Batteries for Apple AirTag, I’m genuinely impressed with how they perform. The OEM quality, 240 milliamp_hours capacity, and complete lack of bitter coating make them a direct match for Apple’s own batteries at a much better value in a 4-pack. I’d recommend these to any AirTag owner who wants hassle-free replacements without worrying about connectivity issues — but if you need a rechargeable option or a longer warranty, you’ll want to look elsewhere.

The six-month warranty is shorter than I’d prefer, but given the 4.7 out of 5 star rating from 478 reviews and the fact that these are sourced from the same manufacturer that supplies Apple, I’m still confident buying them. For the convenience of having four spares on hand and zero installation fuss, these are my go-to AirTag batteries now.
