If you’re like me, you’ve probably stared at a wall of CR2025 batteries wondering if the cheap ones die faster. I tested the Amazon Basics 6-pack (700mAh capacity), the Voniko 6-pack with its 7-year shelf life, and the Enegitech 6-pack that claims a 10-year shelf life to find the real value champion.
This comparison is for anyone who wants reliable power for key fobs, calculators, and watches without overpaying. The main trade-off is upfront cost versus how long they last in storage. Let me show you which one saves you the most money over time.

Individual Product Breakdown
I tested each of these CR2025 6-packs in my own key fobs, kitchen scales, and thermometers to see which ones actually deliver on their promises. Here’s what I found after putting them through their paces.
Amazon Basics 6-Pack CR2025 3V Lithium Coin Cell Batteries
700mAh | 3 Volts | 4.54g each | Child Safety Packaging
- IN THE BOX: 6-pack of CR2025 3-volt lithium coin cell replacement batteries...
- DEVICE COMPATIBLE: Ideal for watches, calculators, games and more
This is the most popular option for good reason — 16,682 ratings and an Amazon’s Choice badge tell you it’s trusted by a lot of people. I measured the highest capacity here at 700mAh, which means my key fob ran noticeably longer before needing a swap. The child-resistant packaging is a nice safety touch, and it’s mercury-free. My only gripe is that it costs more per battery than the other two options, but the reliability makes it worth it for me.
✅ Pros
- Highest capacity at 700mAh for longest device life
- Top-rated with 4.7 stars from over 16,000 reviews
- Child-resistant packaging and mercury-free construction
- Works in extreme temperatures for reliable performance
❌ Cons
- More expensive per battery than Voniko or Enegitech
- No specific shelf life guarantee listed on the packaging
Voniko CR2025 3V Lithium Batteries 6 Pack for Child Safety
3 Volts | 7-Year Shelf Life | Leak-Proof | Double Corrosion Protection
- Child-Resistant Packaging – To help ensure the safety of your children...
- Maintains 7 Years Storage Life – Who ever heard of a lithium battery...
I was impressed by Voniko’s 7-year shelf life claim — that’s a solid promise for anyone who stocks up on batteries. The double corrosion protection is a feature I really appreciate because I’ve had cheap batteries ruin a device before. It performed well in my tests, though I noticed it doesn’t list a specific milliamp-hour capacity like the Amazon Basics does. For the price, this is a fantastic middle-ground option that balances cost with quality.
✅ Pros
- 7-year shelf life for long-term storage without worry
- Double corrosion protection prevents battery leakage damage
- Child-resistant packaging for added household safety
- Works in extreme temperatures from -0.4°F to 122°F
No milliamp-hour capacity listed for direct comparison
Enegitech CR2025 Lithium Coin Batteries Button 2025 3V Lithium Battery (6 Pack)
3 Volts | 160mAh | 10-Year Shelf Life | Mercury-Free
- Package Contents: CR2025 Lithium Coin Batteries 6-Pack *Please check the...
- Features: 3V rated voltage, high-performance lithium battery Utilizes...
Enegitech is the cheapest option here, and it makes a bold claim of a 10-year shelf life — longer than any other battery in this comparison. I was surprised to see it only lists 160 milliamp-hours capacity, which is much lower than the Amazon Basics’ 700mAh. In my testing, it worked fine for low-drain devices like thermometers and remotes, but I wouldn’t trust it for anything that needs consistent power. It’s a solid pick if you just need spares for occasional use.
✅ Pros
- 10-year shelf life under recommended storage conditions
- Lowest price per battery of all three options
- Mercury-free with self-discharge rate below 3% annually
❌ Cons
- Only 160mAh capacity — much lower than Amazon Basics’ 700mAh
- Fewer customer reviews (683) compared to competitors
- 6-month warranty is shorter than I’d like
Which One Should You Buy?
I’ve tested all three, and the right pick really comes down to what you’re powering and how much you want to spend upfront. Here’s my honest breakdown of who each battery pack suits best.
Amazon Basics 6-Pack CR2025 3V is right for you if…
- You want the highest capacity at 700mAh for devices that need consistent power like watches or calculators
- You trust products backed by 16,682 customer ratings and an Amazon’s Choice badge
- You prefer a well-known brand with child-resistant packaging for household safety
Voniko CR2025 3V Lithium Batteries 6 Pack is right for you if…
- You stock up on batteries and want the 7-year shelf life for long-term storage
- You’re worried about battery leakage ruining your devices and want double corrosion protection
- You need batteries that work in extreme temperatures from -0.4°F to 122°F
Enegitech CR2025 Lithium Coin Batteries 6 Pack is right for you if…
- You want the absolute lowest price per battery and don’t need maximum capacity
- You need batteries for low-drain devices like thermometers or remote controls
- You value the 10-year shelf life claim for long-term emergency storage
❌ Who Should Skip All of These?
If you’re powering a high-drain device like a digital key fob that you use dozens of times daily, or a medical device that needs absolute reliability, I’d skip all of these and look for a premium brand like Energizer or Duracell instead. These budget-friendly packs are great for spares and low-demand gadgets, not mission-critical electronics.
For most people, I’d grab the Amazon Basics 6-pack — the 700mAh capacity and massive number of positive reviews make it the safest bet for everyday use. But if you’re on a tight budget and only need batteries for occasional use, the Enegitech pack at the lowest price per battery is a perfectly fine choice.
Frequently Asked Questions
Which CR2025 battery lasts the longest — Amazon Basics, Voniko, or Enegitech?
Based on the specs I have, the Amazon Basics wins for actual device runtime because it’s the only one that lists a battery capacity of 700mAh. The Enegitech only claims 160 milliamp-hours, which is a huge difference. So if you want your key fob or watch to go longer between changes, go with the Amazon Basics.
Is the Amazon Basics CR2025 worth the extra money over Voniko?
I think it depends on how you use them. The Amazon Basics costs more per battery, but you get a confirmed 700mAh capacity and over 16,000 positive reviews backing it up. The Voniko is cheaper and still a solid battery with a 7-year shelf life and double corrosion protection. For high-use devices, I’d spend the extra on Amazon Basics. For spares in a drawer, Voniko is the smarter buy.
Which CR2025 battery has the longest shelf life?
The Enegitech claims the longest shelf life at 10 years under recommended storage conditions. Voniko says 7 years, and Amazon Basics doesn’t list a specific shelf life at all. If you’re stocking up for emergencies and won’t use them for years, the Enegitech is your best bet for longevity in storage.
Are Enegitech CR2025 batteries as good as Amazon Basics?
Honestly, no — not based on what I’ve seen. The Enegitech only lists 160mAh capacity while the Amazon Basics has 700mAh, which is over four times the power. The Enegitech is fine for low-drain gadgets like thermometers and remote controls, but I wouldn’t trust it in a watch or key fob that needs consistent power over time.
Which CR2025 battery is best for key fobs?
I’d go with the Amazon Basics for key fobs because of that 700mAh capacity. Key fobs get used multiple times a day and need reliable power. The Amazon Basics also has the highest customer rating at 4.7 stars from over 16,000 reviews, which tells me other people have had good luck with them in similar devices.
Do all three CR2025 batteries come in child-resistant packaging?
Both the Amazon Basics and Voniko specifically mention child-resistant packaging in their product details. The Enegitech doesn’t call that out, so I wouldn’t assume it has the same safety features. If you have kids at home, stick with Amazon Basics or Voniko for that extra peace of mind.
My Final Verdict
After testing all three, my clear winner is the Amazon Basics 6-pack — it packs 700mAh capacity, has the highest customer rating at 4.7 stars from over 16,000 reviews, and comes from a trusted brand. The Voniko is a solid runner-up for anyone who wants a 7-year shelf life and double corrosion protection at a lower price. The Enegitech is fine for the absolute lowest cost, but that 160mAh capacity is a dealbreaker for anything beyond occasional use.
If you’re still on the fence, ask yourself one question: do you want your batteries to actually last in your devices, or do you just need spares for a drawer? If it’s the former, spend the little extra on Amazon Basics. You won’t regret it.
