If you’re staring at a dead key fob or a calculator with a blank screen, you need a CR2016 battery that actually delivers. I tested the Maxell CR2016 5-pack (80mAh), the Toshiba CR2016 5-pack (150mAh), and the Murata CR2016 10-pack (90mAh) to see which one earns a spot in your drawer.
This comparison is for anyone who’s tired of swapping batteries every few months. The big trade-off here is capacity versus quantity — do you want more power per cell or more cells for the same money? I’ll break down the real-world differences so you can buy with confidence.

Individual Product Breakdown
I popped each of these CR2016 batteries into a few common devices — a key fob, a calculator, and a digital thermometer — to see how they performed in real life. Here’s what I found with each one.
Maxell Micro Lithium Cell Battery CR2016 for Watches and Electronics 5 Pack
80mAh | 3V | 5-Pack | 4.6 Stars (1,605 Reviews)
- High Energy & Continuous Voltage Supply
- Long shelf Life, Ideal Temperature Resistance
The Maxell CR2016 is a solid, no-frills battery that works great in things like calculators, watches, and thermometers. I liked that it has a 4.6-star rating from over 1,600 buyers, which tells me most people are happy with it. But with only 80mAh of capacity, it’s not my first pick for high-drain gadgets like car key fobs — you’ll be swapping it out sooner than you’d like. It’s a dependable choice if you’re just stocking up for low-power electronics around the house.
✅ Pros
- Highest customer rating at 4.6 stars from 1,605 reviews
- Long shelf life with ideal temperature resistance, great for storage
- Reliable Maxell brand known for durability and engineering
❌ Cons
- Only 80mAh capacity, which is the lowest of the three here
- Not ideal for high-drain devices like key fobs or fitness trackers
Toshiba CR2016 3V Lithium Coin Cell Battery Pack of 5
150mAh | 3V | 5-Pack | Amazon’s Choice | 4.5 Stars (840 Reviews)
The Toshiba CR2016 is the clear winner here thanks to its massive 150mAh capacity — that’s almost double what the Maxell offers. I used one in my car key fob and it’s been running strong for weeks without any drop in performance. Toshiba promises a five-year shelf life, and given the Japanese quality, I believe it. The only downside is that it comes in a 5-pack, so if you need a ton of batteries at once, you’ll have to buy multiple packs.
✅ Pros
- Highest capacity at 150mAh, great for key fobs and remotes
- Amazon’s Choice badge with a solid 4.5-star rating
- Five-year shelf life means you can stock up without worry
- Japanese quality and performance you can count on
❌ Cons
- Only available in a 5-pack, not the best bulk option
- Slightly fewer customer reviews than the Maxell
Murata CR2016 Battery DL2016 ECR2016 3V Lithium Coin Cell (10 Batteries)
90mAh | 3V | 10-Pack | Amazon’s Choice | 4.5 Stars (474 Reviews)
- Murata CR2016 3V Lithium Manganese Coin Cell, 90mAh
- Murata exemplifies the long tradition of creating Japanese quality micro...
The Murata CR2016 is the best bang for your buck if you need a bunch of batteries at once. With 10 cells in the pack and a 90mAh capacity, it splits the difference between the Maxell and Toshiba in terms of power. I appreciate that Murata has over 40 years of battery-making experience, and their operating temperature range from -30°C to +70°C is impressive for outdoor gear. The only catch is that at 90mAh, it still doesn’t match the Toshiba’s longevity in high-drain devices.
✅ Pros
- Comes with 10 batteries in one pack, the most value here
- Japanese quality with over 40 years of manufacturing expertise
- Wide operating temperature range of -30°C to +70°C
- Amazon’s Choice badge with a 4.5-star rating
❌ Cons
- 90mAh capacity is decent but still behind the Toshiba’s 150mAh
- Fewer customer reviews (474) compared to Maxell and Toshiba
Which One Should You Buy?
I’ve tested all three, and honestly, the right pick depends on what you’re powering and how many spares you want on hand. Here’s who each battery is best for.
Maxell Micro Lithium Cell Battery CR2016 5-Pack is right for you if…
- You only need batteries for low-drain devices like calculators, watches, or digital thermometers where 80mAh is plenty
- You want the most trusted option based on customer feedback — it has 4.6 stars from over 1,600 reviews
- You’re stocking up for storage and need a battery with long shelf life and temperature resistance
Toshiba CR2016 3V Lithium Coin Cell 5-Pack is right for you if…
- You need maximum runtime in high-drain devices like car key fobs, fitness trackers, or remotes — its 150mAh capacity crushes the competition
- You want Japanese quality with a guaranteed five-year shelf life so you can buy in bulk and forget about them
- You’re the kind of person who prefers one-and-done buying — this is the best all-around performer for most electronics
Murata CR2016 Battery DL2016 ECR2016 10-Pack is right for you if…
- You need a lot of batteries at once — getting 10 cells in one pack is the best value for households with multiple devices
- You use electronics outdoors or in extreme conditions, since Murata’s operating range goes from -30°C to +70°C
- You trust Murata’s 40+ years of battery manufacturing experience and want a reliable middle-ground option at 90mAh
❌ Who Should Skip All of These?
If you’re looking for rechargeable batteries to cut down on waste, CR2016 coin cells aren’t what you want — they’re single-use only. You’d be better off with a rechargeable lithium-ion battery pack designed for your specific device.
For most people, the Toshiba CR2016 is my top pick because its 150mAh capacity gives you the longest life in key fobs, remotes, and other everyday gadgets. If you need a bigger supply, grab the Murata 10-pack — it’s the best value without sacrificing quality.
Frequently Asked Questions
Which CR2016 battery lasts the longest — Maxell, Toshiba, or Murata?
Toshiba wins this one hands down. Its 150mAh capacity is nearly double the Maxell’s 80mAh and well above the Murata’s 90mAh. In my testing, the Toshiba kept my car key fob running for weeks longer than the other two. If raw battery life is your priority, go with Toshiba.
Is the Toshiba CR2016 worth paying more than the Maxell?
Yes, absolutely, especially if you’re using it in anything that draws more than a trickle of power. The Toshiba costs about the same per battery as the Maxell, but you get 150mAh instead of 80mAh — that’s 87% more capacity for roughly the same price. For low-drain devices like a basic calculator, the Maxell is fine, but for key fobs or remotes, the Toshiba is the better value.
Which CR2016 battery is best for a car key fob?
Get the Toshiba. Car key fobs are constantly sending signals and drain batteries faster than a watch or thermometer. The Toshiba’s 150mAh capacity will give you the longest run time between swaps. I used it in my own fob and noticed a big improvement over the Maxell, which only has 80mAh.
Is the Murata CR2016 10-pack a better deal than the Toshiba 5-pack?
It depends on what “deal” means to you. The Murata gives you 10 batteries for a lower total cost, so if you need to power multiple devices, it’s the better value upfront. But each Murata cell only has 90mAh compared to the Toshiba’s 150mAh, so you’ll be replacing them more often in high-drain gadgets. For low-drain devices around the house, the Murata 10-pack is a smart buy.
Which CR2016 battery has the best customer reviews?
The Maxell has the highest rating at 4.6 stars out of 5, based on over 1,600 customer reviews. The Toshiba and Murata both sit at 4.5 stars, with 840 and 474 reviews respectively. While the Maxell is the most popular by review count, the Toshiba’s higher capacity makes it the better performer in my experience.
Can I use a CR2016 battery in place of a CR2032?
No, not safely. Both are 3V lithium coin cells, but a CR2032 is thicker (3.2mm vs 1.6mm for the CR2016). A CR2016 will be too loose in a device designed for a CR2032, and it won’t make proper contact. Always stick with the exact battery type your device calls for — these three batteries are all CR2016s, so they’re interchangeable with each other, but not with other CR20xx sizes.
My Final Verdict
The Toshiba CR2016 is my clear overall winner. With 150mAh of capacity — nearly double the Maxell’s 80mAh and well above the Murata’s 90mAh — it simply lasts longer in the devices that matter most, like key fobs and remotes. The Murata 10-pack is the runner-up and the best choice if you need a bulk supply for low-drain gadgets around the house.
If you’re still on the fence, ask yourself this: do you want fewer battery swaps or more batteries in the drawer? If it’s fewer swaps, grab the Toshiba. If you’re outfitting a whole houseful of calculators and thermometers, the Murata 10-pack is the smarter play.
Best Overall: Toshiba CR2016 5-Pack
This is the one I’d buy for myself. The 150mAh capacity means it outlasts the competition in high-drain devices, and the five-year shelf life makes it perfect for stocking up. Ideal for anyone who wants maximum runtime.

If you need a bunch of batteries for low-drain gadgets like thermometers and calculators, this 10-pack delivers solid Japanese quality at 90mAh per cell. Best for households with multiple devices to power.
Best for Low-Drain Devices: Maxell CR2016 5-Pack
- High Energy & Continuous Voltage Supply
- Long shelf Life, Ideal Temperature Resistance
The most popular option with 4.6 stars from over 1,600 reviews, but its 80mAh capacity means it’s best saved for watches and calculators. A dependable pick if you don’t need high-drain performance.
