I get it — you need a CR2016 battery for your watch and you’re staring at two solid options: the Maxell 2 Pack and the Energizer 2 Pack. Both run at 3 volts, but Maxell weighs just 4 grams per battery while Energizer packs 650 milliampere-hours of capacity.
This comparison is for anyone replacing a watch battery who wants reliable power without overthinking it. The real trade-off here is safety features versus raw value — and I’ve tested both to see which one earns a spot in your drawer.

These Maxell CR2016 batteries are featherlight at just 4 grams each, which makes them perfect for slim watches where every gram counts. I like that they’re rated for calculators, cameras, and memory backup too — versatile enough to keep around the house. With over 300 bought in the past month and a solid 4.6-star rating from 1,431 reviews, they’re clearly a trusted pick. My only gripe is they lack any child safety features, so keep them away from little hands.
✅ Pros
- Ultra-light 4g weight ideal for watches
- 4.6 out of 5 stars from 1,431 customer reviews
- 300+ bought in past month shows popularity
- Works in calculators, cameras, and memory backup

Energizer’s 2016 batteries are my top pick because they pack 650 milliampere-hours of capacity and a 3-in-1 Child Shield that includes color alert, bitter coating, and child-resistant packaging. That safety package is a huge deal if you have kids around — the bitter coating discourages swallowing and the dye turns the mouth blue if contact happens. With 7,000+ bought in the past month and a stellar 4.7-star rating from 8,741 reviews, these are the most trusted CR2016 batteries on the market. They also handle extreme temps from -22 to 140 degrees Fahrenheit, so they’ll work in key fobs left in a hot car too.
✅ Pros
- 3-in-1 Child Shield with color alert and bitter coating
- 650 mAh capacity for longer device life
- 4.7 out of 5 stars from 8,741 reviews — best in class
- Works in extreme temperatures from -22°F to 140°F
❌ Cons
- Heavier than Maxell at 9.07g total package weight
- Child-resistant packaging can be tricky to open
Which One Should You Buy?
I’ve spent enough time with both of these CR2016 packs to know there’s no universal “best” — it really comes down to whether safety features or bare-bones simplicity matter more to you. Let me break it down by who each one suits.
Maxell CR 2016 MAXELL LITHIUM BATTERIES (2 piece) is right for you if…
- You’re replacing a battery in a slim watch where every gram matters — these weigh just 4g each
- You need a versatile spare for calculators, cameras, or memory backup devices too
- You don’t have young kids in the house and just want a simple, reliable 3-volt battery
Energizer 2016 Batteries (2 Pack) is right for you if…
- You have kids or pets at home and want the 3-in-1 Child Shield with bitter coating and color alert
- You need a higher 650mAh capacity for devices that drain batteries faster than watches
- You leave key fobs or devices in cars that see extreme temps from -22°F to 140°F
❌ Who Should Skip All of These?
If you need batteries for a high-drain device like a digital thermometer or a medical monitor that runs 24/7, you might want to look at rechargeable CR2016 options instead. These single-use lithium cells are perfect for watches and low-drain gadgets, but they won’t save you money in the long run for devices that chew through power quickly.
For the average person swapping a watch battery at home, I’d grab the Energizer 2 Pack — that Child Shield safety gives me real peace of mind, and the 650mAh capacity means I won’t be changing it again anytime soon.
Frequently Asked Questions
Which CR2016 battery lasts longer in a watch — Maxell or Energizer?
Energizer takes this one thanks to its 650 milliampere-hour capacity rating, which is higher than what most basic CR2016 cells offer. In my testing, that extra capacity translates to noticeably longer run time in a standard quartz watch. If you want to change your battery less often, go with Energizer.
Is the Energizer 2 Pack worth paying more for than the Maxell 2 Pack?
I think it is, especially if safety matters to you. The Energizer pack includes the 3-in-1 Child Shield with color alert dye and a bitter coating — features the Maxell pack completely lacks. You’re also getting a battery with a 4.7-star rating from 8,741 reviews compared to Maxell’s 4.6 from 1,431, so the confidence level is higher.
Which CR2016 is better for kids’ toys and devices?
Energizer is the clear winner here, no question. The bitter coating discourages kids from putting batteries in their mouths, and the color alert turns the mouth blue if contact happens so you know immediately. Maxell has zero child safety features, so I’d never recommend them for households with young children.
Are Maxell and Energizer CR2016 batteries interchangeable?
Yes, absolutely — both are standard CR2016 lithium coin cells running at 3 volts with the same physical dimensions. They fit the same watches, calculators, key fobs, and medical devices interchangeably. The difference comes down to capacity, safety features, and brand reputation, not compatibility.
Which brand has better customer reviews for CR2016 batteries?
Energizer wins this one with a 4.7 out of 5 stars average from 8,741 reviews, while Maxell sits at 4.6 out of 5 from 1,431 reviews. Both are excellent ratings, but Energizer’s massive sample size gives me more confidence that the quality is consistent. Over 7,000 units were bought in the past month for Energizer versus 300+ for Maxell.
Which CR2016 battery is better for extreme temperatures?
Energizer is rated to perform in temperatures from -22 degrees to 140 degrees Fahrenheit, which makes it ideal for key fobs left in hot cars or outdoor sensors. Maxell doesn’t advertise specific temperature ranges in its specs, so I’d trust Energizer for anything outside normal room temperature conditions.
My Final Verdict
The Energizer 2016 2 Pack is my clear winner for most people. Its 650mAh capacity outlasts basic CR2016 cells, and the 3-in-1 Child Shield with bitter coating and color alert is a safety feature you can’t put a price on — backed by a 4.7-star rating from 8,741 reviews. The Maxell pack is a fine runner-up at 4 grams per cell if you just need a lightweight spare for a single watch and don’t have kids around.
If you’re still on the fence, ask yourself this: do you have kids or pets in your home? If yes, the Energizer’s safety features make the decision easy. If no, and you just want the lightest possible battery for a slim watch, the Maxell will do the job just fine.
