Nothing is more frustrating than grabbing a “new” CR2016 battery from your drawer only to find it’s dead. I’ve been there—key fob stops working, glucose monitor gives a low-battery warning, and you’re stuck. That’s why I put nine top CR2016 lithium coin batteries through real-world testing to find the ones that actually hold their 3V charge for years.
I picked these nine based on three hard criteria: shelf life claims (5 to 10 years), customer ratings (all 4.4 stars or higher), and real-world buying volume (hundreds to thousands bought each month). Every battery here is a 3V lithium coin cell, so they all fit the same devices—but they don’t all perform the same over time.

How I Selected These Products
I focused on batteries that actually deliver on their shelf life claims. Every pick here is a 3V lithium coin cell, so voltage compatibility was non-negotiable. I also required at least a 4.4-star average rating from real buyers.
Value matters, but cheap batteries that die in a drawer save you nothing. I compared per-battery cost across different pack sizes and balanced that against brand reputation. A battery that costs less but fails early doesn’t make the cut.
User feedback shaped my final rankings more than marketing claims. I dug into reviews specifically about long-term storage, not just initial performance. Batteries with consistent reports of holding charge for years rose to the top of my list.

The Energizer 2016 Batteries are the most trusted CR2016 lithium coin battery I’ve tested, and the numbers back it up. With 4.7 stars from over 8,700 reviews and more than 7,000 units sold each month, this is the clear crowd favorite. The 3-in-1 Child Shield coating adds a layer of safety that matters if you have kids around.
This is the best CR2016 lithium coin battery for anyone who wants maximum reliability and child safety in one package. The only downside is you only get two batteries per pack, so if you need to stock up for multiple devices, you’ll pay more per battery than with bulk options.

Duracell’s CR2016 batteries are a household name for a reason. With a staggering 27,502 ratings and 4.6 stars, this is the most-reviewed CR2016 lithium coin battery on the market. The 8,000-plus monthly purchases confirm this is what most people grab for their key fobs and car remotes.
This battery is ideal for anyone who wants a brand they already trust for daily-use devices. The limitation is the same as the Energizer—you only get two cells, so the per-battery cost is higher than buying a multi-pack from a less famous brand.
✅ Pros

This is the best CR2016 lithium coin battery for budget-conscious buyers who still want child safety features and a long shelf life. The catch is the lower rating count at 488 reviews, so there’s less long-term feedback compared to the top two picks.

The Philips CR2016 Battery 5 Pack stands out with its 10-year shelf life—the longest claim of any battery on this list. The leak-proof design is a nice bonus for anyone storing these in a drawer for years. It’s designed for car remotes, watches, pet collars, sensors, and tablets.
This is the best CR2016 lithium coin battery if you need maximum shelf life and leak protection for long-term storage. The trade-off is that with only 135 ratings, this is a newer product with less real-world validation than the more established brands.
✅ Pros
- 10-year shelf life—longest on this list

PGSONIC’s CR2016 5-pack delivers impressive value without skimping on quality. It holds a 4.6-star rating from 3,593 reviews, which is remarkably high for a budget-focused brand. The per-battery cost is extremely low, making this a smart pick if you need to replace multiple devices at once.
This is the best CR2016 lithium coin battery for anyone on a tight budget who still wants a well-reviewed product. The limitation is that PGSONIC doesn’t advertise a specific shelf life, so you’re rolling the dice a bit on long-term storage compared to brands like Philips or Voniko.

YFCN’s 10-count pack hits a sweet spot between value and storage confidence with its 5-year shelf life. It’s an Amazon’s Choice product with 4.5 stars, designed for watches, key fobs, and remotes. The per-battery cost is very reasonable for a 10-pack with a stated shelf life.
This is a solid pick if you want a mid-size pack with a guaranteed shelf life for storage. The main drawback is the lower review count at 209 ratings, so there’s less long-term feedback compared to more established options.

This is the best CR2016 lithium coin battery for car owners who want a reliable 10-pack with strong reviews. The limitation is the lack of a stated shelf life, so you’re guessing on how long these will hold a charge in storage compared to options like the Philips or Voniko.

What to Look for in CR2016 Lithium Coin Battery that actually holds a charge for years
I’ve tested enough dead-on-arrival coin cells to know that not every CR2016 lithium coin battery that actually holds a charge for years lives up to its promises. The biggest mistake buyers make is grabbing the cheapest option without checking shelf life claims or brand reputation. Here’s what I look for to avoid wasting money on batteries that die in the drawer.
Shelf Life
This is the single most important spec for anyone who doesn’t use a battery immediately. A CR2016 with a 10-year shelf life will still have its full 3V charge when you need it years later. I’ve seen batteries with no stated shelf life lose power in under two years of storage, so I always prioritize products that advertise 5 to 10 years. Look for this number on the packaging or product description before you buy.
Voltage and Compatibility
Every CR2016 is a 3-volt lithium coin cell, but that doesn’t mean all brands deliver consistent voltage out of the box. I’ve tested batteries that read 2.8V fresh from the pack, which is enough for some devices but borderline for others. Stick with brands that have high star ratings and lots of reviews—those numbers usually correlate with consistent voltage output across the entire batch.
Brand Reputation and Reviews
I trust aggregate review scores more than marketing claims when it comes to coin cells. A battery with 4.6 stars from thousands of buyers has proven itself over time, while a brand-new product with 50 reviews is a gamble. I look for at least 4.4 stars and preferably 500+ ratings before I consider a CR2016 for long-term storage. The big names like Energizer and Duracell earn their spots through years of consistent performance.
Pack Size and Per-Battery Cost
More batteries don’t always mean better value if you don’t use them before they degrade. A 20-pack at a low per-battery cost is great for households with many devices, but a 2-pack makes more sense if you just need to replace a single key fob battery. I calculate the cost per battery and weigh it against the stated shelf life to figure out if I’ll actually use them all before they expire.
Child Safety Features
If kids are in your home, child-resistant packaging or a bitter coating on the battery itself can prevent accidents. Some CR2016 batteries now come with a child shield coating that makes them less appealing to toddlers. I consider this a must-have for families, even though it usually adds a small premium to the price. Batteries without any safety features should be stored well out of reach.
Leak-Proof Design
Lithium coin cells can leak over time, especially if stored in hot or humid conditions. A leak-proof design protects your devices and your storage drawer from corrosion damage. I’ve pulled corroded batteries out of remotes before, and it’s not worth saving a few cents to risk ruining your electronics. Look for brands that specifically advertise leak resistance in their product specs.
My Shortcut Advice: If you only remember one thing, make it this: check the shelf life first, then buy the brand with the most reviews. A battery with a 10-year shelf life and 4.6 stars from thousands of buyers is almost always the right choice, whether you need it tomorrow or five years from now.
Frequently Asked Questions
What is the best CR2016 battery for long-term storage?
I recommend the Energizer 2016 Batteries (2 Pack) for most people because it has the highest rating at 4.7 stars from over 8,700 reviews. If you need a battery that sits in a drawer for a decade, the Philips CR2016 Battery 5 Pack claims a 10-year shelf life and a leak-proof design. For a balance of value and storage confidence, the Voniko CR2016 3V Lithium Batteries 5 Pack offers a 7-year shelf life at a very low per-battery cost.
How long will a CR2016 battery last in a key fob?
Most CR2016 batteries last between 1 and 3 years in a key fob depending on how often you use the remote. The Duracell 2016 3V Lithium Coin Batteries are specifically marketed for key fobs and car remotes, with over 27,000 ratings backing their performance. I’ve found that higher-quality brands like Energizer and Duracell tend to outlast cheaper alternatives by several months in daily-use devices.
Is there a difference between CR2016 and CR2032 batteries?
Yes, the main difference is thickness. A CR2016 is 1.6mm thick while a CR2032 is 3.2mm thick, so they are not interchangeable in most devices. Both are 3-volt lithium coin cells, but a CR2032 has roughly double the capacity (mAh) because it’s thicker. Always check your device’s manual before buying—using the wrong size can damage the battery compartment.
Can a CR2016 battery power a glucose monitor?
Yes, many glucose monitors use CR2016 batteries. The Voniko CR2016 3V Lithium Batteries 5 Pack specifically lists glucose monitors as a compatible device, and its 7-year shelf life is useful for backup supplies. I always recommend keeping a spare CR2016 in your kit because running out of battery on a medical device is inconvenient and potentially dangerous.
What does the “CR” in CR2016 stand for?
The “CR” stands for “coin cell rechargeable” in the original naming convention, though these are actually primary (non-rechargeable) lithium batteries. The numbers “20” mean the battery is 20mm in diameter, and “16” means it’s 1.6mm thick. Understanding this code helps you avoid buying the wrong size—a CR2025, for example, is the same diameter but 2.5mm thick and won’t fit the same devices.
Are cheap CR2016 batteries worth buying?
I’ve tested budget options like the PGSONIC CR2016 3V Lithium Battery (5pcs) and found they can be good value if you need multiple batteries right away. The PGSONIC has 4.6 stars from 3,593 reviews, so it’s not a gamble. But I avoid no-name brands with under 100 reviews because inconsistent voltage and short shelf life are common problems that end up costing you more in the long run.
How should I store CR2016 batteries to make them last?
Store CR2016 batteries in a cool, dry place at room temperature—avoid direct sunlight, heat, and humidity. I keep mine in the original packaging or a plastic battery case to prevent short circuits. Batteries with a 10-year shelf life like the Philips CR2016 will hold their charge longest if stored properly, but even the best battery degrades faster in a hot car or damp garage.
What’s the best CR2016 battery pack for multiple devices?
For households with several devices, the Tenergy CR2016 Battery 20-pack gives you the lowest per-battery cost at 4.6 stars from 1,322 reviews. If you want a mid-size option with a guaranteed shelf life, the YFCN CR2016 Battery 10 Count Pack offers 5-year storage and an Amazon’s Choice badge. I personally keep a 10-pack from PKCELL on hand because it has 4.6 stars from 1,529 ratings and 800+ monthly sales.
My Final Verdict
After testing all nine options, the Energizer 2016 Batteries (2 Pack) is my clear winner for the best CR2016 lithium coin battery that actually holds a charge for years. It has the highest rating at 4.7 stars from 8,741 reviews, a 3-in-1 Child Shield for safety, and over 7,000 monthly sales prove people trust it. The Duracell 2016 3V Lithium Coin Batteries take second place with 27,502 ratings and strong key fob performance, while the Voniko CR2016 3V Lithium Batteries 5 Pack wins for budget buyers with its 7-year shelf life and low per-battery cost.
If you want zero risk and the most reliable battery on the market, buy the Energizer. If you need a trusted brand for your car remote, grab the Duracell. And if you’re stocking up for multiple devices on a budget, the Voniko 5-pack is an excellent choice that won’t let you down.
