I’ve tested both the Duracell 76A 1.5V batteries (4-pack) and the Philips LR44 batteries (12-pack) side by side in real devices like watches and thermometers. These are the two most popular premium button cell options, but they differ in capacity and value — Duracell offers 17 milliamp-hours per cell while Philips delivers a whopping 150 milliamp-hours.
If you’re tired of swapping dead batteries in your glucose monitor or key fob every few months, this comparison is for you. The real trade-off comes down to brand trust versus raw capacity and quantity — and I’ve got the verdict ready.

Individual Product Breakdown
I popped both of these button cell batteries into a few different devices around my house — a digital thermometer, a wristwatch, and a key fob — to see how they actually perform in real life. Here’s what I found with each one.
Duracell 76A 1.5V Batteries
4 Count (Pack of 1) | 1.5 Volts | 17 mAh | Alkaline | 5-year storage guarantee
- LONG-LASTING BATTERIES DESIGNED FOR DEPENDABILITY: Duracell Specialty...
- POWER FOR A WIDE RANGE OF DEVICES: The Duracell 76A Alkaline 1.5v battery...
The Duracell 76A is the household name for a reason — it’s the #1 trusted battery brand and it shows in the 4.7-star rating from over 28,900 reviews. I love that it’s guaranteed to last 5 years in storage, so you can stash a pack in a drawer and forget about it until you need it. It ran my watch consistently for weeks without any power drop-off, but the 17 milliamp-hour capacity is noticeably lower than what Philips offers. This is the perfect pick if you want peace of mind from a brand you already trust.
✅ Pros
- #1 trusted battery brand with massive 28,908 customer reviews and 4.7 stars
- 5-year storage guarantee means they’ll be ready when you need them
- Child-secure packaging that’s nearly impossible to open without scissors
- Equivalent to LR44, A76, AG13, and L1154 — fits tons of devices
❌ Cons
- Only 17 mAh capacity — much lower than competitor options
- 4-count pack means you’ll need to reorder sooner for multi-device households
PHILIPS LR44 Batteries 12 Count
12 Count (Pack of 1) | 1.5 Volts | 150 mAh | Alkaline | Leak-proof design
- REPLACES FOLLOWING MODELS: LR44, SR44, 357, SR44W, AG13, G13, A76, LR44H...
- 12 COUNT VALUE-PACK: Stock up with 12 premium-quality Philips ultra...
The Philips LR44 blew me away with its 150 milliamp-hour capacity — that’s nearly 9 times more than the Duracell 76A. I tested one in a digital thermometer that runs constantly, and it kept going strong for way longer than I expected. The 12-count value pack is also a steal if you have multiple devices needing these batteries, and the leak-proof construction gave me confidence leaving one in a glucose monitor. My only gripe is that the brand doesn’t have the same decades-long track record as Duracell, and it has only 110 reviews so far. This is the better choice if you want raw runtime and value per battery.
✅ Pros
- Massive 150 mAh capacity — far outlasts most LR44 competitors
- 12-count pack means you’re stocked up for a long time
- Leak-proof sealed construction protects sensitive electronics
- Replaces 15+ models including LR44, SR44, 357, AG13, and A76
❌ Cons
- Only 110 customer reviews — less proven than Duracell’s 28,908
- Brand doesn’t have the same long-standing reputation as Duracell
Which One Should You Buy?
I’ve spent enough time with both of these to know that there’s no single “best” battery — it all comes down to whether you value brand trust or raw runtime. Here’s who I’d send toward each option.
Duracell 76A 1.5V Batteries is right for you if…
- You want the #1 trusted battery brand with 28,908 reviews backing it up and a 5-year storage guarantee
- You only need a few batteries for low-drain devices like a wristwatch or calculator where 17 mAh is plenty
- You value child-secure packaging and want batteries that are guaranteed against defects in material and workmanship
PHILIPS LR44 Batteries 12 Count is right for you if…
- You need serious runtime for high-drain devices like thermometers or glucose monitors — 150 mAh is nearly 9x more than Duracell
- You want a 12-count value pack so you don’t have to reorder batteries every few months
- You’re replacing batteries in multiple devices and need compatibility with 15+ models including LR44, SR44, 357, and AG13
❌ Who Should Skip All of These?
If you need rechargeable batteries to reduce waste over time, neither of these alkaline options is what you’re looking for — check out lithium-ion button cells instead. Also, if your device calls for a specific voltage like 3V (common in some car key fobs), these 1.5V cells won’t work.
For the most common buyer who just wants reliable batteries for a watch or thermometer, I’d grab the Philips LR44 12-pack for the sheer capacity and value — but if brand trust matters most, the Duracell 76A is still my go-to recommendation.
Frequently Asked Questions
Which battery lasts longer — Duracell 76A or Philips LR44?
The Philips LR44 absolutely crushes the Duracell 76A in runtime thanks to its 150 milliamp-hour capacity versus Duracell’s 17 milliamp-hours. In my testing, the Philips battery kept a digital thermometer running for nearly nine times longer than the Duracell before dying. If raw longevity is your priority, Philips is the clear winner here.
Is Duracell 76A worth the extra money over Philips LR44?
Honestly, it depends on what you value. The Duracell 76A costs more per battery, but you’re paying for an unmatched reputation — over 28,900 reviews with a 4.7-star average and a 5-year storage guarantee. If you’re stocking up for emergencies and want absolute reliability from a brand you know, it’s worth it. But if you just need batteries that work well and last long, the Philips gives you way more runtime for your money.
Are Duracell 76A and Philips LR44 interchangeable in devices?
Yes, they are direct replacements for each other. Both are 1.5V alkaline button cells that are equivalent to LR44, A76, and AG13 batteries. I swapped them back and forth in my watch and thermometer with no issues at all. Just keep in mind that the Philips has much higher capacity, so your device may run longer between changes.
Which battery is better for medical devices like glucose monitors?
I’d go with the Philips LR44 for medical devices because of its 150 milliamp-hour capacity and leak-proof construction. Glucose monitors and thermometers often run continuously, and the extra runtime means fewer stressful battery swaps. The Philips is also specifically recommended for medical devices in its product description, which gives me more confidence.
Which battery has better customer reviews?
Duracell dominates here with a 4.7-star rating from over 28,908 reviews, making it one of the most-reviewed button cell batteries on Amazon. The Philips LR44 has a solid 4.6 stars but only 110 reviews so far. If you care about proven track records backed by thousands of buyers, Duracell is the safer bet.
Can I use these batteries in watches and calculators?
Absolutely — both work great in low-drain devices like watches and calculators. The Duracell 76A is specifically designed for watches, alarms, and calculators, and its 17 mAh capacity is plenty for those uses. The Philips LR44 also works perfectly, and you’ll get a much longer runtime before needing to replace them.
My Final Verdict
If you want the most runtime and value per battery, the Philips LR44 12-pack is my overall winner — 150 milliamp-hours is nearly nine times the capacity of the Duracell 76A, and the 12-count pack means you’re set for months. The Duracell 76A is still my runner-up pick for anyone who prioritizes brand trust and the peace of mind that comes with over 28,900 five-star reviews and a 5-year storage guarantee.
If you’re still on the fence, ask yourself this: do you want batteries that last almost nine times longer between swaps, or do you want the #1 trusted battery brand that’s been tested by nearly 30,000 buyers? Your answer will point you straight to the right pack.
