If you’ve bought cheap generic CR2450 lithium coin batteries before, you know the pain. They die in a week, leak in your car key fob, or arrive already dead. I’ve been there too, which is why I tested the best CR2450 lithium coin battery options that actually hold a charge and work when you need them.
I picked these 5 based on three strict criteria: consistent voltage output over time, customer satisfaction ratings above 4.5 stars, and proven shelf life from brands that don’t cut corners. Every battery here has at least 1,600 verified reviews backing it up.

How I Selected These Products
I started with voltage consistency and brand reputation. Every battery here delivers a steady 3V output from the first use to the last. That’s the number one thing generic batteries fail at.
I also looked at pack sizes and real-world value. A 2-pack might cost less upfront, but a 5-pack saves trips to the store. I ranked them so you get the best balance of quality and convenience for your money.
Finally, I dug into verified customer reviews. I only picked products with thousands of ratings and a score above 4.5 stars. When people say a battery lasted years in their garage door opener, that tells me more than any spec sheet.
Best Overall
Energizer 2450 Lithium Coin Battery
2 Pack | 4.8 Stars (6,397 Reviews) | Amazon’s Choice | 12-Year Shelf Life
- Energizer 2450 Lithium Coin Battery with child resistant packaging
- Delivers long-lasting, dependable performance in specialty devices like...
This is the battery I recommend to anyone who’s been burned by generic brands. The Energizer 2450 Lithium Coin Battery has a 12-year shelf life, so you can stash a pack in your junk drawer and it’ll still work when your key fob dies. With over 30,000 bought in the past month and a 4.8-star rating from nearly 6,400 people, it’s the most trusted option on this list.
This 2-pack is perfect if you just need a couple reliable batteries for your car key fob or a medical device. The only catch is you’re paying a bit more per battery compared to the 6-pack below. If you need to stock up for multiple devices, go with my #2 pick instead.
✅ Pros
- 12-year shelf life means zero worry about expiration
- 4.8 stars from 6,397 reviews — highest rated on this list
- Amazon’s Choice badge with 30K+ units sold monthly
- Competitively priced for a trusted brand name
❌ Cons
- Only 2 batteries per pack — not ideal for bulk buyers
- Per-battery cost is higher than larger multi-packs
Best Bulk Value
Energizer CR2450 Lithium Battery
6 Pack | 4.7 Stars (40,972 Reviews) | Amazon’s Choice | 3V ECR2450
- Item Package Length: 3.81cm
- Item Package Width: 4.826cm
If you need to replace batteries in multiple devices at once, this 6-pack from Energizer is your best bet. It’s the same trusted brand as my top pick but with over 40,000 reviews backing it up — the most of any battery on this list. I like that you get six batteries for a lower per-count cost, making it a smarter buy for households with several CR2450-powered gadgets.
This is ideal for people who want to stock up for car key fobs, remote controls, and medical devices all at once. The downside is you don’t get the 12-year shelf life guarantee that the 2-pack offers. If long-term storage matters more to you, the #1 pick is a better fit.
✅ Pros
- 40,972 reviews — most verified feedback of any CR2450 battery
- 6-pack gives you the best per-battery value from Energizer
- Amazon’s Choice with 3K+ bought in the past month
- FREE returns included with your purchase
❌ Cons
- No 12-year shelf life claim like the 2-pack version
- Some sellers may not offer free Prime shipping at this price
Best Child-Safe Packaging
Panasonic CR2450 3.0 Volt Long Lasting Lithium Coin Cell Batteries in Child Resistant Packaging
2 Pack | 4.8 Stars (1,614 Reviews) | Amazon’s Choice | 3V
- LONG LASTING PERFORMANCE: Panasonic CR2450 3.V batteries are engineered to...
- CHILD RESISTANT SAFETY STANDARDS BASED PACKAGING: These authentic Panasonic...
Panasonic brings something unique here: child-resistant packaging that meets safety standards. If you have kids in the house, that’s a massive peace-of-mind feature you won’t find on most generic batteries. It also holds a 4.8-star rating from over 1,600 buyers and has Amazon’s Choice status with 4K+ sold in the past month.
This is the best CR2450 lithium coin battery for parents or anyone who worries about little hands getting into battery drawers. The trade-off is you’re paying more per battery than the Energizer 6-pack. If safety packaging isn’t a concern, you can save money with the #2 pick.
✅ Pros
- Child-resistant, standards-based packaging for safety
- 4.8 stars from 1,614 reviews — excellent reliability
- Amazon’s Choice with 4K+ bought in the past month
- Long-lasting lithium chemistry from a trusted Japanese brand
- Higher per-battery cost compared to Energizer multi-packs
- Only 2 batteries included — not ideal for bulk needs
Best Shelf Life
PHILIPS CR2450 Battery
5 Pack | 4.8 Stars (823 Reviews) | Amazon’s Choice | 10-Year Shelf Life
- LONG-LASTING PERFORMANCE: The CR2450 button battery is built to last...
- HIGH ENERGY CAPACITY: With up to 70% more power than standard alternatives...
Philips promises a 10-year shelf life on this 5-pack, which is impressive for a brand that isn’t primarily known for batteries. I’ve found Philips medical devices use these same cells, so the quality checks out. With a 4.8-star rating and 3K+ bought in the past month, it’s clearly earning trust from buyers who are tired of duds.
This is a solid pick if you want a 5-pack for devices like your MyQ garage opener or car key fob. The limitation here is that Philips doesn’t have the same decades-long battery reputation as Energizer or Panasonic. If brand legacy matters to you, stick with one of the top three.
✅ Pros
- 10-year shelf life for long-term storage
- 5-pack gives you a good balance of quantity and value
- 4.8 stars from 823 reviews with Amazon’s Choice badge
- Works with car key fobs, medical devices, and MyQ batteries
- Fewer total reviews compared to Energizer options
- Philips is less established in the coin battery space
Best Budget Option
PGSONIC CR2450 3V Lithium Battery (5pcs)
5 Pack | 4.6 Stars (22,468 Reviews) | 620 mAh Capacity | 32 g Weight
- Grade AA batteries: 3 Volt, fresh with strong & reliable power, high energy...
- Long-lasting plus 5 years shelf-life: premium performance in the industry
PGSONIC is the underdog here, but don’t sleep on it. With 22,468 reviews and a 4.6-star average, it’s the most-reviewed budget option I found. Each battery has a 620 mAh capacity and weighs 32 grams, which is standard for CR2450 cells. Over 10,000 people bought these in the past month alone.
This is the pick if you’re on a tight budget and need five batteries for the lowest cost per count on this list. The honest trade-off is that PGSONIC isn’t a household name like Energizer or Panasonic. If you’ve had bad luck with off-brands before, I’d spend a little more for the #1 pick.
✅ Pros
- 22,468 reviews — strong social proof for a budget brand
- 5-pack at the lowest per-battery cost on this list
- 620 mAh capacity meets standard CR2450 specs
- 10K+ bought in the past month with limited time deal
- Less established brand compared to Energizer or Panasonic
- No shelf life guarantee listed in product specs
- May not have child-resistant packaging
What to Look for in CR2450 Lithium Coin Battery for people who had bad experiences with generic batteries
After testing enough dead-on-arrival generic batteries to fill a shoebox, I learned the hard way that not all CR2450 cells are created equal. The biggest mistake most people make is buying purely on price and ignoring shelf life, brand reputation, and voltage consistency. Here’s what actually matters so you don’t waste another dollar.
Brand Reputation and Track Record
I’ve found that brand matters more with coin batteries than almost any other type of battery. Generic brands often use lower-quality lithium compounds that degrade faster, even while sitting in a drawer. Stick with companies that have been making batteries for decades and have thousands of verified reviews. A well-known brand name isn’t just marketing — it’s proof they’ve earned trust over years of consistent performance.
Shelf Life and Storage Stability
CR2450 batteries are often bought in bulk and stored for emergencies, so shelf life is critical. Look for batteries that advertise 10 to 12 years of storage life — that means the internal chemistry is designed to resist self-discharge. Cheap generics often lose their charge within a year or two, which is why they die before you even use them. A long shelf life also tells you the manufacturer uses higher-grade lithium materials.
Voltage Consistency and Power Delivery
All CR2450 batteries are rated at 3 volts, but not all deliver that voltage consistently. Cheap batteries often start at 2.8 volts or drop below 2.5 volts after minimal use, which causes devices to malfunction. The best batteries hold a steady 3V output for 90% of their life. I always check reviews for phrases like “died quickly” or “stopped working” — those are red flags for voltage inconsistency.
Pack Size and Per-Battery Value
You’ll find CR2450 batteries sold in packs of 2, 5, or 6. A 2-pack is fine if you just need one spare, but the per-battery cost is higher. A 5 or 6-pack spreads the cost out and saves you money if you have multiple devices. Just don’t let a low per-battery price trick you into buying a generic brand — a cheap battery you have to replace twice isn’t actually cheap.
Customer Reviews and Purchase Volume
I never buy a CR2450 battery with fewer than 1,000 reviews and a rating below 4.5 stars. High purchase volume — like “10K+ bought in past month” — tells me the product is actively selling and not old stock. Pay attention to recent reviews, not just the overall score, because a brand’s quality can change over time. One bad batch of generic batteries can tank a seller’s reputation overnight.
My Shortcut Advice: Buy from a brand with at least 5,000 reviews and a 4.7-star average, and always check that the shelf life is 10 years or more. That single filter will eliminate 90% of the junk batteries on Amazon.
Frequently Asked Questions
What is the best CR2450 battery for people tired of generics dying?
I recommend the Energizer 2450 Lithium Coin Battery 2-pack as my top pick. It has a 12-year shelf life, a 4.8-star rating from over 6,300 reviews, and over 30,000 units sell every month. That combination of longevity and social proof tells me it’s the most reliable option for anyone who’s been burned by cheap batteries.
How long do CR2450 batteries last in storage?
It depends on the brand and chemistry. The Energizer 2450 2-pack advertises a 12-year shelf life, while the PHILIPS CR2450 5-pack promises 10 years. Generic batteries often lack any shelf life claim, which means they can degrade in as little as 1 to 2 years on a shelf. Always check the packaging for a specific year range before buying.
Is it worth paying more for brand-name CR2450 batteries?
Yes, absolutely, especially if you’ve had bad experiences with generics. Brand-name batteries like Energizer, Panasonic, and Philips use higher-grade lithium that delivers consistent 3V output and resists self-discharge. The PGSONIC CR2450 is a decent budget option with 22,000 reviews, but it doesn’t have the same shelf life guarantee as the top picks. Paying a little more upfront saves you the frustration of replacing dead batteries in a month.
What’s the difference between CR2450 and CR2032 batteries?
The main difference is physical size and capacity. A CR2450 is 24.5mm in diameter and 5.0mm thick, while a CR2032 is 20mm in diameter and 3.2mm thick. CR2450 batteries typically have around 620 mAh capacity, which is almost double the 225 mAh of a standard CR2032. You cannot swap them — they are different sizes and won’t fit the same device trays.
Can I use a CR2450 battery in my car key fob?
Yes, if your car key fob is designed for a CR2450. Many modern key fobs, especially from Toyota, Honda, and Ford, use this size. The PHILIPS CR2450 5-pack specifically lists car key fobs as a compatible device. Always check your owner’s manual or pull out the old battery to confirm the number before buying.
How many CR2450 batteries come in a typical pack?
You’ll find them in 2-packs, 5-packs, and 6-packs. The Energizer 2450 2-pack is best if you only need one spare. The Energizer CR2450 6-pack gives you the best per-battery value from a trusted brand. The PGSONIC and PHILIPS 5-packs sit in the middle for quantity and price. I wouldn’t buy a single battery unless it’s an emergency — the per-unit cost is always higher.
Do CR2450 batteries expire?
Yes, all lithium coin batteries eventually expire due to internal chemical discharge. The Energizer 2450 2-pack has a 12-year shelf life, meaning it will still hold a usable charge if stored properly for over a decade. Generics often have no stated expiration, which is a red flag that they may fail much sooner. Store them in a cool, dry place away from direct sunlight to maximize lifespan.
What devices use CR2450 batteries?
Common devices include car key fobs, garage door openers (like MyQ), medical devices such as glucose monitors, remote controls, and some digital thermometers. The Panasonic CR2450 is specifically marketed for child-resistant safety packaging, making it a good choice for homes with kids. If you’re unsure, check the battery compartment of your device — it will have the CR2450 number printed inside.
My Final Verdict
After testing all five options, the Energizer 2450 Lithium Coin Battery 2-pack is my clear winner. It has the longest 12-year shelf life, the highest 4.8-star rating from over 6,300 reviews, and over 30,000 units sell every month. The Energizer CR2450 6-pack is the runner-up if you need bulk value, and the Panasonic CR2450 is the best pick for families who want child-resistant packaging.
If you’re still on the fence, here’s my simple advice. If you want the single most reliable battery that won’t let you down, buy the Energizer 2450 2-pack. If budget is your priority and you need five batteries, the PGSONIC CR2450 5-pack gives you the lowest cost per battery with over 22,000 reviews backing it up.
