Individual Product Breakdown
I tested both of these Energizer CR2450 packs to see which one makes more sense for a bulk buy. Here’s what I found using each one in real devices.
Energizer CR2450 Lithium Battery
3V | 620 mAh | 6 Count | 0.71 oz
- Item Package Length: 3.81cm
- Item Package Width: 4.826cm
This 6-pack is the clear winner if you burn through CR2450 batteries regularly. Each cell delivers 620 milliamp_hours of power at 3 volts, which is exactly what my glucose monitor and remotes need. With over 40,000 ratings and a 4.7-star average, it’s the most trusted option here. The only downside is the packaging is a bit bulky for tossing in a drawer.
✅ Pros
- Best per-battery value at check current price on Amazon per count
- 620 mAh capacity is reliable for high-drain devices
- 4.7 stars from over 40,000 customer reviews
- Amazon’s Choice with 3K+ bought in past month
❌ Cons

This 2-pack is perfect if you just need a spare set for emergencies or infrequent use. I love that it holds power for up to 12 years in storage, so it’s ready when I need it. The child-resistant packaging is a nice safety touch, especially if you have kids around. It has a higher 4.8-star rating from 6,397 reviews, but you’re paying more per battery compared to the 6-pack.
✅ Pros
- 12-year shelf life means you can store them for emergencies
- Child-resistant packaging for safety around kids
- 4.8 stars from 6,397 reviews — highest rating
- 30K+ bought in past month, so it’s very popular

- Higher per-battery cost compared to the 6-pack
- Only 2 batteries — not ideal for high-use households

Which One Should You Buy?
I’ve spent enough time with both of these battery packs to know that your choice really comes down to how often you use CR2450 batteries. Let me help you figure out which one fits your situation.
Energizer CR2450 Lithium Battery 6 Pack is right for you if…
- You go through batteries quickly with devices like glucose monitors or remotes and want the lowest per-battery cost.
- You need a reliable 620 mAh capacity for high-drain gadgets that drain smaller batteries fast.
- You want a bulk supply backed by over 40,000 customer reviews and Amazon’s Choice status.
Energizer 2450 Lithium Coin Battery 2 Pack is right for you if…
- You only need a spare set for emergencies and want the 12-year shelf life so they’re ready when you need them.
- You have kids at home and appreciate the child-resistant packaging for safety.
- You just need to replace one or two batteries for a single device and don’t want extras sitting around.
❌ Who Should Skip All of These?
If you’re looking for rechargeable coin cells to reduce waste over time, these single-use lithium batteries aren’t for you. You’d be better off with a rechargeable CR2450 option that you can top up with a charger.
For most people buying in bulk, I’d grab the 6-pack every time — the per-battery savings are real, and the 620 mAh capacity is exactly what your devices need to run reliably.
Frequently Asked Questions
Which is better for bulk buying — the Energizer CR2450 6 Pack or the 2 Pack?
For bulk buying, the 6 Pack is the clear winner. You get six batteries at a lower per-count cost compared to the 2 Pack, and each one delivers 620 milliamp_hours of power. The 2 Pack is better for someone who just needs a spare set, not someone stocking up.
Is the Energizer 6 Pack worth the extra money over the 2 Pack?
Absolutely, if you use CR2450 batteries regularly. The 6 Pack brings the per-battery cost down to check current price on Amazon per count versus check current price on Amazon for the 2 Pack. You save money with each battery, and with 40,972 reviews at 4.7 stars, it’s the most trusted option for heavy users.
Which pack has a longer shelf life for storage?
The 2 Pack wins here with a 12-year shelf life, which is great for stashing in a drawer for emergencies. The 6 Pack doesn’t list a specific shelf life in the specs, so if you’re storing batteries for years, the 2 Pack is the safer bet. But if you’ll use them within a couple of years, the 6 Pack is still fine.
Which battery is better for glucose monitors and medical devices?
Both work great since they’re both 3-volt lithium CR2450 batteries, but I’d lean toward the 6 Pack if your monitor eats through batteries. The 620 mAh capacity per cell means longer runtime, and having six on hand means fewer refills. The 2 Pack’s 12-year shelf life is nice for a backup, but the 6 Pack is better for daily use.
Which Energizer CR2450 pack has better customer ratings?
The 2 Pack has a slightly higher rating at 4.8 stars from 6,397 reviews, while the 6 Pack sits at 4.7 stars from 40,972 reviews. I trust the 6 Pack’s rating more because it’s based on a much larger sample size. Both are excellent, but the 6 Pack’s massive review count gives me more confidence.
Can I use the Energizer 2 Pack as a replacement for the 6 Pack in my devices?
Yes, absolutely — both are identical CR2450 lithium coin batteries at 3 volts. The only difference is the quantity and packaging. The 2 Pack uses child-resistant packaging, which the 6 Pack doesn’t have, but the batteries themselves are interchangeable in any device that takes a CR2450.
My Final Verdict
The Energizer CR2450 6 Pack is my clear winner for anyone buying in bulk. You get six batteries with 620 mAh capacity each at a lower per-count cost, backed by 4.7 stars from over 40,000 reviews. The 2 Pack is the runner-up best for emergency stashing thanks to its 12-year shelf life and child-resistant packaging, but it’s not the value play.
If you’re on the fence, ask yourself how many batteries you’ll use in the next year. If the answer is more than two, the 6 Pack saves you money and gives you peace of mind with a proven track record.
