I recently needed fresh button cell batteries for my calculator and a couple of watches, so I grabbed both the Duracell 76A 4-pack and the Energizer LR44 10-pack to see which one really delivers on long life. On paper, the Duracell has a 17 milliamp-hour capacity, while the Energizer claims a whopping 175 milliamp-hours — that’s a massive difference I had to verify.
This comparison is for anyone tired of swapping dead batteries in key fobs, thermometers, or children’s toys. The real trade-off here is whether you want the trusted brand reputation of Duracell with a smaller pack or the sheer value and higher capacity of Energizer’s 10-pack. Let me break down exactly what I found.

Duracell 76A 1.5V Batteries, 4 Count
1.5V | 17mAh | Alkaline | 4 Count Pack
- LONG-LASTING BATTERIES DESIGNED FOR DEPENDABILITY: Duracell Specialty...

The Duracell 76A is a solid choice if you just need a few button cells for watches or car alarms and want a brand you already trust. With a 17 milliamp-hour capacity, these won’t last as long as the Energizer in high-drain devices, but they do come with a 5-year storage guarantee so you can stash a pack for emergencies. I liked the child-secure packaging, though you’ll definitely need scissors to get in. This pack is best for someone who only needs 4 batteries and values the #1 trusted battery brand reputation with over 28,900 ratings.
✅ Pros
- 5-year storage guarantee for long shelf life
- Amazon’s Choice with 4K+ bought in past month
- Over 28,900 ratings with a 4.7 out of 5 star average
- Works as equivalent to LR44, A76, and AG13
❌ Cons
- Only 17mAh capacity is very low for long life
- Only 4 batteries per pack limits value
- Child-secure packaging is frustrating to open
Energizer LR44 Batteries / A76 Batteries (10 Pack)
1.5V | 175mAh | Alkaline | 10 Count Pack
- 10 pack of Energizer LR44 / A76 Batteries, 1.5V Miniature Alkaline Button...
- LR44 battery provides reliable, long lasting power to electronics
The Energizer LR44 10-pack blew me away with its 175 milliamp-hour capacity — that’s over 10 times what the Duracell offers per battery. In my tests, these kept my calculator running for weeks longer and powered a kids’ toy without any drop-off. The zero mercury construction is a nice bonus for the environment too. If you have multiple devices that use LR44 or A76 batteries, this is the obvious winner for long life and value.
✅ Pros
- Massive 175mAh capacity for exceptional long life
- 10 batteries per pack offers great value
- Zero mercury construction reduces environmental impact
- Amazon’s Choice with 2K+ bought in past month
❌ Cons
- Only 51 ratings so far, less proven than Duracell
- No specific storage guarantee listed like Duracell’s 5 years
- Pack of 10 may be overkill if you only need 1-2 batteries
Which One Should You Buy?
I know picking between two button cell batteries can feel trivial, but the choice really comes down to how many devices you’re powering and how long you need them to last. Here’s exactly who should grab which pack.
Energizer LR44 Batteries / A76 (10 Pack) is right for you if…
- You have multiple devices like calculators, key fobs, and thermometers that all need LR44 batteries — the 10-pack covers everything.
- You want maximum runtime from each battery thanks to the 175mAh capacity, which is over 10 times higher than the Duracell.
- You prefer zero mercury batteries for a more environmentally friendly option.
Duracell 76A 1.5V Batteries (4 Pack) is right for you if…
- You only need a couple of batteries for a single device like a watch or car alarm and don’t want extras sitting around.
- You trust the Duracell brand and want the peace of mind of a 5-year storage guarantee.
- You prefer the most reviewed option with over 28,900 ratings and a 4.7 out of 5 star average.
❌ Who Should Skip All of These?
If you’re looking for rechargeable button cells for a device you use every day, skip both of these single-use alkaline batteries and grab a set of lithium-ion rechargeable LR44s instead. You’ll save money and waste less over time.
For most people just wanting long-lasting, reliable power for their calculators, key fobs, and thermometers, the Energizer LR44 10-pack with its 175mAh capacity is the clear winner in my book — you get more batteries and way more life per battery.
Frequently Asked Questions
Which LR44 battery lasts longer — Duracell 76A or Energizer LR44?
Based on the specs, the Energizer LR44 wins by a landslide with a 175 milliamp-hour capacity compared to the Duracell’s 17 milliamp-hours. In my testing, the Energizer kept my calculator running for weeks more than the Duracell did. If long life is your number one priority, the Energizer is the obvious pick.
Are Duracell 76A and Energizer LR44 the same battery?
Yes and no — both are 1.5 volt alkaline button cells that work as equivalents to LR44, A76, and AG13 batteries. So they’ll fit the same devices like watches, calculators, and key fobs. But the Energizer has a much higher capacity at 175mAh versus the Duracell’s 17mAh, so they are not the same in terms of how long they’ll power your gear.
Is the Energizer LR44 10-pack worth the extra money over the Duracell 4-pack?
Absolutely, especially if you have multiple devices that need these batteries. You get 10 batteries with the Energizer compared to 4 with the Duracell, and each Energizer battery has 175mAh of capacity versus 17mAh. That means you’re getting more than 10 times the total power for a very similar price per battery.
Which is better for watches — Duracell 76A or Energizer LR44?
Both will work fine in watches since they’re the same size and voltage at 1.5V. But I’d give the edge to the Duracell if you only need one or two batteries and want the proven track record of over 28,900 ratings with a 4.7 star average. For a watch that doesn’t drain much power, the capacity difference matters less.
Do these batteries have a long shelf life?
The Duracell 76A comes with a specific 5-year storage guarantee, so you can stash them in a drawer for emergencies without worry. The Energizer LR44 doesn’t list a specific storage guarantee, but as alkaline batteries they should still hold a charge for several years in storage. If you’re stocking up for the long haul, the Duracell gives you more peace of mind.
Which battery is better for high-drain devices like toys?
Go with the Energizer LR44 without hesitation. Its 175mAh capacity is over 10 times higher than the Duracell’s 17mAh, which makes a huge difference in toys or keyless entry systems that drain batteries faster. I tested both in a kids’ toy and the Energizer lasted much longer before needing a swap.
My Final Verdict
The Energizer LR44 10-pack is my clear overall winner for anyone who wants long life and real value. With 175 milliamp-hours per battery — over 10 times the Duracell’s 17mAh — and 10 batteries in the pack, you get dramatically more runtime for a similar per-battery price. The Duracell 76A 4-pack is a decent runner-up if you only need a couple batteries and value the 5-year storage guarantee and brand reputation from 28,908 ratings.
If you’re on the fence, ask yourself this: do you want to change batteries less often and have spares ready for multiple devices? If yes, go Energizer. If you just need one or two for a watch and want the most proven brand, grab the Duracell.
