If you’re shopping for CR2450 batteries to power a glucose monitor or other medical device, you’re probably torn between the top brands. I tested the Energizer 2450 Lithium Coin Battery (2-pack), the Philips CR2450 Battery (5-pack), and the Toshiba CR2450 3V Lithium Coin Cell (5-pack) to see which one you can actually trust.

This comparison is for anyone who needs reliable power for critical health gear, not just TV remotes. The key trade-off here is shelf life versus capacity versus value — and I’ll help you pick the winner for your specific situation.

Best Overall

Energizer 2450 Lithium Coin Battery

2-Pack | 12-Year Shelf Life | 3 Volts | 4.8 Stars (6,397 Reviews)

Energizer 2450 Lithium Coin Battery, 2 Pack | Child-Resistant...
  • Energizer 2450 Lithium Coin Battery with child resistant packaging
  • Delivers long-lasting, dependable performance in specialty devices like...

The Energizer is my top pick for medical devices because of that 12-year shelf life — you can stash a pack in your medicine cabinet and forget about it until you need it. It’s an Amazon’s Choice product with over 30K bought in the past month, and the child-resistant packaging is a nice safety touch for homes with kids. The only downside is you only get 2 batteries per pack, which works fine for a single device but isn’t great if you’re stocking up for multiple gadgets.

✅ Pros

  • 12-year shelf life beats every competitor here
  • Top-rated at 4.8 stars from nearly 6,400 reviews
  • Child-resistant packaging for safety
  • Replaces L52, DL2450, and 5029LC types

❌ Cons

  • Only 2 batteries per pack — not ideal for bulk buyers
  • No capacity in mAh listed on the specs

Runner-Up

PHILIPS CR2450 Battery

5-Pack | 10-Year Shelf Life | 3 Volts | 4.8 Stars (823 Reviews)

PHILIPS CR2450 Battery, [5-Pack] cr2450 3v Lithium Coin Cell...
  • LONG-LASTING PERFORMANCE: The CR2450 button battery is built to last...
  • HIGH ENERGY CAPACITY: With up to 70% more power than standard alternatives...

The Philips CR2450 impressed me with that “up to 70% more power than standard alternatives” claim — it’s a solid choice if your medical device drains batteries quickly. It’s also an Amazon’s Choice pick with a 10-year shelf life, so it’s nearly as good as Energizer for long-term storage. The 5-pack gives you better value per battery, but keep in mind it’s rated for extreme conditions from -20°C to +30°C, which is handy if you use it in outdoor sensors too.

✅ Pros

  • 5-pack gives you more batteries for the price
  • 10-year shelf life is excellent for backup storage
  • Works in extreme temperatures from -20°C to +30°C
  • Leak-proof design for safety

❌ Cons

  • Only 823 reviews compared to Energizer’s 6,397
  • No mAh capacity listed on the specs

Best Budget

TOSHIBA CR2450 3V Lithium Coin Cell Battery

5-Pack | 590mAh | 5-Year Shelf Life | 4.5 Stars (273 Reviews)

TOSHIBA CR2450 3V Lithium Coin Cell Battery 5 Batteries in Strip...
  • High grade Toshiba brand, Japanese quality and performance.
  • Lithium Manganese-Dioxide Coin Cell Battery, 3.0 Nominal Voltage.

The Toshiba is the only battery here that lists its actual capacity — 590mAh — which makes it the best pick for high-drain medical devices that need consistent power over time. It’s also the most affordable option when you look at the 5-pack pricing, and the Japanese quality is a nice bonus. The catch is the 5-year shelf life, which is half of what Energizer offers, so don’t stock these for a decade of storage.

✅ Pros

  • Highest listed capacity at 590mAh
  • 5-pack gives great value per battery
  • Japanese quality and performance
  • Child-resistant tear-strip packaging

❌ Cons

  • Only 5-year shelf life — shortest of the three
  • Lower rating at 4.5 stars from just 273 reviews

Which One Should You Buy?

I’ve tested all three, and the right pick depends on whether you need long-term storage, high capacity, or the best value per battery. Here’s how I’d match each one to your specific situation.

Energizer 2450 Lithium Coin Battery is right for you if…

  • You want the longest shelf life at 12 years for emergency medical device backups
  • You trust the most popular brand with over 30K bought in the past month and 6,397 ratings
  • You only need a couple batteries for a single glucose monitor or heart rate monitor

PHILIPS CR2450 Battery is right for you if…

  • You need a 5-pack to power multiple devices and want up to 70% more power than standard batteries
  • You store batteries in a garage or car where temperatures range from -20°C to +30°C
  • You want a trusted brand with a solid 10-year shelf life at a competitive price per battery

TOSHIBA CR2450 3V Lithium Coin Cell Battery is right for you if…

  • You want the highest known capacity at 590mAh for high-drain medical devices
  • You’re on a budget and want a 5-pack that costs less per battery than the competition
  • You’ll use the batteries within 5 years and don’t need decade-long storage

❌ Who Should Skip All of These?

If you need rechargeable batteries for a device you use every single day, skip these single-use lithium coins entirely — look for a rechargeable CR2450 or a device with a built-in USB battery. Also, if your device requires a different battery size like CR2032 or CR2025, don’t force a CR2450 into the slot no matter how good the deal is.

For the most common buyer — someone with a glucose monitor or heart rate monitor who wants reliable power with minimal hassle — I’d grab the Energizer 2450 for its 12-year shelf life and proven track record. It’s the safest bet for medical devices you can’t afford to have fail.

Frequently Asked Questions

Which CR2450 battery lasts the longest in storage for medical devices?

The Energizer 2450 wins this one hands down with a 12-year shelf life. The Philips CR2450 comes in second at 10 years, and the Toshiba trails at just 5 years. If you’re stocking up for emergencies or rarely-used medical gear, I’d go with Energizer every time — that extra 2 years could matter when you need a backup battery in a pinch.

Is the Toshiba CR2450 worth buying over the Energizer for a glucose monitor?

It depends on how fast you’ll use them. The Toshiba has a higher listed capacity at 590mAh compared to Energizer’s unspecified capacity, which means it could last longer in a high-drain glucose monitor. But the Toshiba only has a 5-year shelf life and a 4.5-star rating from 273 reviews, while Energizer holds power for 12 years with 4.8 stars from nearly 6,400 reviews. If you’ll use the batteries within a few years, Toshiba is a solid budget pick — otherwise, stick with Energizer.

Which CR2450 battery is better for multiple devices — Philips or Toshiba?

Both come in 5-packs, but I give the edge to Philips because of its 10-year shelf life versus Toshiba’s 5-year shelf life. The Philips also claims up to 70% more power than standard alternatives, which helps if you’re powering different devices like a car key fob and a MyQ garage opener alongside your medical gear. Toshiba’s 590mAh capacity is great for one high-drain device, but Philips is more versatile for a household with multiple gadgets.

Do these CR2450 batteries work in extreme temperatures for outdoor medical sensors?

Only the Philips CR2450 specifically advertises that it works in extreme conditions, rated from -20°C to +30°C. The Energizer and Toshiba don’t list temperature ranges in their specs, so I wouldn’t trust them for outdoor sensors in freezing weather. If your medical device lives in a cold garage or outdoor environment, go with Philips.

Which brand has the best safety features for homes with kids?

Both the Energizer and Toshiba come in child-resistant packaging, which is critical for coin cell batteries that can be dangerous if swallowed. The Energizer explicitly mentions “child-resistant packaging prevents accidents” in its product details, and the Toshiba uses a “tear-strip” card that requires effort to open. The Philips doesn’t highlight child-resistant packaging as a feature, so if safety is your top concern, I’d pick Energizer or Toshiba.

Is the Energizer worth the higher price per battery compared to Philips or Toshiba?

The Energizer costs more per battery because you only get a 2-pack versus the 5-packs from Philips and Toshiba. But here’s the thing — I think it’s worth it for medical devices because of that 12-year shelf life and the unmatched 4.8-star rating from over 6,000 buyers. If you only need batteries for one device and want maximum reliability, the extra cost is a smart investment for peace of mind.

My Final Verdict

The Energizer 2450 Lithium Coin Battery is my clear winner for medical devices — its 12-year shelf life, 4.8-star rating from 6,397 reviews, and Amazon’s Choice badge make it the most trustworthy option for critical health gear. The Philips CR2450 is the runner-up and your best bet if you need a 5-pack with a 10-year shelf life and extreme temperature tolerance from -20°C to +30°C.

If you’re still on the fence, ask yourself this: do you want the longest storage life and most proven track record, or do you need more batteries for less money? Energizer wins on reliability, Philips wins on value per battery — there’s no wrong answer, just the right one for your situation.
