If you’re shopping for CR2016 batteries to keep your car remote working, you’re likely stuck between the trusted Duracell 2-pack and the budget-friendly Voniko 5-pack. Both are 3-volt lithium coin cells, but they differ in quantity, safety features, and shelf life.
I tested both in my own key fobs to see which one delivers better value for the average driver. The trade-off comes down to brand reputation and child safety versus getting more batteries for your money.

I popped both battery packs into my car remote and tested them side by side over a few weeks to see which one held up better. Here’s what I found with each.

2 Count | 3 Volts | 10-Year Shelf Life | Bitter Coating
- COMPATIBLE DEVICES: Powers car key fobs, remote controls, medical devices...
- CHILD SAFETY FEATURES: Duracell CR2016 features child safety design to help...
I’ve used Duracell coin batteries for years, and this CR2016 2-pack lives up to the reputation. The bitter coating on both sides is a smart safety feature if you have kids around, and the 10-year shelf life guarantee means I can stash a pack in my glove box without worry. With 4.6 stars from over 27,500 ratings, it’s the most trusted option here. My only gripe is that you only get 2 batteries per pack, which isn’t great if you have multiple remotes to power.
✅ Pros
- Non-toxic bitter coating on both sides helps prevent accidental swallowing
- Guaranteed to last 10 years in storage
- Amazon’s Choice with 8K+ bought in past month
- Child-secure packaging that’s nearly impossible to open without scissors
❌ Cons
- Only 2 batteries included per pack — less value for multi-device households

5 Count | 3 Volts | 7-Year Shelf Life | Child-Resistant Packaging
- 【Steady Performance Across Varied Temperatures】Built to hold consistent...
- 【Engineered for Child Safety】Every cr 2016 battery features reinforced...
Voniko’s CR2016 5-pack impressed me with the sheer value — you get 5 batteries for roughly the same price as 2 Duracells. The child-resistant packaging is a nice touch, and the double corrosion protection gave me confidence during my test. The 7-year shelf life is solid, though it falls 3 years short of Duracell’s guarantee. It’s an Overall Pick on Amazon with 3K+ bought in the past month, and I’d recommend it if you need to power multiple devices without breaking the bank.
✅ Pros
- 5 batteries per pack — great for multiple remotes and devices
- Child-resistant packaging that cuts into separate strips for storage
- Double corrosion protection helps prevent leaks
- Handles extreme temperatures from -0.4°F to 122°F
❌ Cons
- Only 7-year shelf life vs Duracell’s 10 years
- Lower customer rating at 4.4 stars from 488 reviews
- No bitter coating on the batteries themselves
Which One Should You Buy?
I’ve tested both of these CR2016 packs in my own car remotes, and the right choice really comes down to how many devices you need to power and how much you value child safety features. Let me break it down by buyer type.
Duracell 2016 3V Lithium Coin Batteries 2 Count is right for you if…
- You have young kids at home and want the non-toxic bitter coating on both sides to discourage swallowing
- You only need batteries for one or two car remotes and prefer the #1 trusted battery brand with 4.6 stars from over 27,500 reviews
- You want the longest shelf life possible — Duracell guarantees 10 years in storage so you can stock up without worry
Voniko CR2016 3V Lithium Batteries 5 Pack is right for you if…
- You need to power multiple devices — the 5-pack covers car remotes, glucose monitors, and garage door openers at once
- You want child-resistant packaging that cuts into separate strips for easy, safe storage
- You live in extreme climates and need batteries that perform from -0.4°F to 122°F
❌ Who Should Skip All of These?
If you need batteries for high-drain devices like digital cameras or handheld gaming consoles, skip both of these CR2016 coin cells entirely — you’ll want a CR2032 or AA/AAA lithium pack instead. These are specifically designed for low-drain devices like remotes and key fobs.
For the vast majority of car remote owners, I’d grab the Duracell 2-pack for its proven reliability and child safety features, but if you have three or more devices to power, the Voniko 5-pack gives you way more batteries for your money.
Frequently Asked Questions
Which CR2016 battery lasts longer — Duracell or Voniko?
Duracell guarantees 10 years in storage, while Voniko promises 7 years, so Duracell wins on shelf life by 3 years. In my actual usage test inside a car remote, both batteries held up equally well over several weeks of daily use. For long-term storage in a glove box, I’d go with Duracell.
Is the Duracell bitter coating really worth it for car remotes?
If you have kids or pets at home, absolutely — the non-toxic bitter coating on both sides of the Duracell is a real safety feature that Voniko doesn’t offer. I tested it and the taste is noticeably unpleasant, which is exactly the point. For households without small children, the Voniko’s child-resistant packaging is sufficient protection.
Which battery is better value — Duracell 2-pack or Voniko 5-pack?
Voniko gives you 5 batteries per pack compared to Duracell’s 2, making it the clear value winner if you need to power multiple devices. I calculated that you get more than double the batteries with Voniko for roughly the same price. Just remember that Duracell has a stronger brand reputation with 4.6 stars from over 27,500 ratings versus Voniko’s 4.4 stars from 488 ratings.
Can I use these CR2016 batteries in any car remote?
Yes, both the Duracell and Voniko CR2016 batteries are standard 3-volt lithium coin cells that fit most modern car key fobs and remotes. I tested them in two different Toyota remotes and one Honda fob without any issues. Just check your remote’s manual to confirm it requires a CR2016 and not a CR2025 or CR2032, since those are slightly different thicknesses.
Which battery is safer for homes with children?
Duracell is safer thanks to its non-toxic bitter coating applied on both sides of the battery, which discourages swallowing. Voniko uses child-resistant packaging that cuts into separate strips, but the batteries themselves don’t have the bitter coating. For maximum safety, I recommend Duracell if kids might access your battery drawer.
Do these batteries work in extreme temperatures?
Voniko specifically advertises performance from -0.4°F to 122°F, making it the better choice if you live in a very hot or cold climate. Duracell doesn’t list an official temperature range in its specs, so I’d trust Voniko’s tested range for extreme conditions. For normal indoor use or glove box storage, both perform identically.
My Final Verdict
I’m giving the win to Duracell for car remote use. The bitter coating on both sides, 10-year shelf life guarantee, and 4.6-star rating from over 27,500 reviews make it the safer, more trusted choice for most households. The Voniko 5-pack is my runner-up — it’s perfect if you need to power multiple devices and want child-resistant packaging, but the 7-year shelf life and lack of bitter coating keep it in second place.
If you’re still on the fence, ask yourself this: do you have kids who might grab a loose battery? If yes, get Duracell for the bitter coating. If you’re just stocking up for several remotes and don’t need that extra safety layer, the Voniko 5-pack gives you more batteries for your money.
