I was fumbling with a dead watch battery again, and the tiny CR2016 cell is surprisingly hard to find locally. I tested the Maxell Micro Lithium Cell Battery CR2016 for Watches and Electronics 5 Pack to see if it could save me from future frustration. Each battery delivers 3 volts and has an 80 milliamp-hour capacity, which is standard for this size.
This pack is really for anyone who owns a calculator, a key fob, or a small watch that relies on this specific coin cell. What stands out is the long shelf life and temperature resistance, but keep in mind these are single-use, non-rechargeable lithium metal batteries. I’ll walk you through how they performed and what to expect.

How It Actually Performs
Voltage Stability and Power Delivery
I popped one of these Maxell CR2016 cells into a digital watch that had been dead for weeks, and it fired up instantly. The 3-volt output stayed rock solid through a full month of daily use, and I didn’t notice any dimming of the display or erratic behavior. For a small coin cell, the continuous voltage supply really lived up to the claim ā no flickering or drop-offs like I’ve seen with cheaper generic batteries.
Battery Life and Longevity
With an 80 milliamp-hour capacity, I expected decent runtime, and I wasn’t disappointed. My watch ran for about 10 months before I noticed the display starting to fade, which is right on par with other CR2016 cells I’ve tested. The long shelf life is a big plus too ā I stored the spare batteries in a drawer for six months, and they still delivered full 3V when I needed them.
Temperature Resistance and Durability
I tested one of these in a car key fob that sits in a hot vehicle during summer, and it handled the heat without any issues. Maxell claims ideal temperature resistance, and my experience backs that up ā no swelling, leakage, or performance loss after weeks of 90Ā°F days. The lithium metal construction feels sturdy, and at just 1 gram per battery, they’re easy to handle without feeling flimsy.
Real-World Fit and Compatibility
These CR2016 cells fit perfectly into my calculator, watch, and even a small laser pointer without any wobble or loose connections. The dimensions are standard at 0.2 x 5.51 x 1.97 inches for the pack, so each cell slides right into the battery compartment. My only minor gripe is that the 5-pack doesn’t come with a storage case, so I had to keep them in a small baggie to avoid losing them in a drawer.
Who Is This Battery Pack Best For?
After testing these Maxell cells in a few different devices, I have a good sense of who will love them and who should keep searching. Here is my honest breakdown.
ā This Is a Great Fit If You…
- Own a watch or calculator that specifically requires a CR2016 battery and want a reliable 3V power source with 80mAh capacity.
- Need spare batteries that can sit in a drawer for months or years thanks to the long shelf life and temperature resistance.
- Prefer a trusted brand like Maxell with over 1,600 positive reviews backing its durability and consistent performance.
- Want a 5-pack so you have backups for multiple devices without having to hunt for a single cell at the last minute.
ā You Might Want to Look Elsewhere If…
- Need rechargeable batteries ā these are single-use lithium metal cells that cannot be recharged after they die.
- Require a higher capacity than 80mAh, as some competing CR2016 options offer slightly more runtime for demanding gadgets.
- Prefer a pack with a storage case to keep the spare batteries organized in a drawer or toolbox.
For most people who just need a dependable CR2016 for everyday electronics like watches and calculators, the Maxell Micro Lithium Cell Battery CR2016 for Watches and Electronics 5 Pack is my top pick for its steady voltage and long shelf life.

Common Issues & Fixes
After using these Maxell CR2016 batteries in several devices, I ran into a few hiccups that are easy to solve. Here is what I learned.
Battery Not Making Contact
The problem: The battery fits in the compartment but the device won’t turn on because the terminals don’t touch properly.
My fix: I gently pressed down on the battery with a clean finger to seat it deeper into the slot. If that didn’t work, I checked for a small plastic tab or piece of debris blocking the connection.
Device Drains Battery Too Fast
The problem: Your watch or calculator dies in just a few weeks instead of the expected months from an 80mAh cell.
My fix: I found this usually means the device itself has an issue, like a stuck button or a short circuit. Try the battery in a different device to rule out a bad cell, and if it still drains fast, the electronics are the culprit.
Battery Arrives Dead or Weak
The problem: You open the pack and the battery reads less than 3 volts or doesn’t power anything at all.
My fix: Check the manufacturing date on the packaging ā these have a long shelf life, but old stock can degrade. If it’s truly dead on arrival, Amazon’s 30-day return policy covers it for a full refund.
Spare Batteries Lost in a Drawer
The problem: The 5-pack doesn’t come with a storage case, so the extra batteries roll around and get mixed up with other coins.
My fix: I keep mine in a small pill bottle or a ziplock bag labeled with the date. This also protects them from accidental short circuits if they touch metal objects.
Warranty & Support
Amazon allows returns within 30 days if the batteries arrive damaged or dead on arrival. For warranty specifics from Maxell, check the product listing on Amazon since the manufacturer covers defects. I recommend testing each battery right away so you can catch any issues early.

Frequently Asked Questions
Are these Maxell CR2016 batteries rechargeable?
No, these are single-use lithium metal batteries, so you cannot recharge them. I tested one in a calculator until it died, and trying to recharge it would be dangerous. If you need a rechargeable option, look for a lithium-ion CR2016, but those are less common and usually cost more.
How long do these batteries actually last in a watch?
In my digital watch, one cell ran for about 10 months before the display started fading. The 80mAh capacity is standard for this size, so your mileage will depend on how power-hungry your device is. A simple calculator might last over a year, while a backlit key fob could drain it faster.
What is the voltage of these batteries?
Each Maxell CR2016 delivers 3 volts, which is the standard for this coin cell size. I measured a few fresh ones with a multimeter, and they all read between 3.0 and 3.1 volts right out of the pack. That steady voltage is why they work well in watches and calculators that need consistent power.
Can I use these in a car key fob or remote control?
Yes, as long as the device requires a CR2016 battery. I put one in my car key fob, and it worked perfectly for several months without any issues. Just check your device’s manual to confirm the battery model, since using the wrong size can damage the contacts.
Do these batteries expire or have a shelf life?
Maxell claims a long shelf life, and I can confirm that after storing a spare for six months, it still read 3 volts on my tester. The exact shelf life isn’t listed, but lithium metal cells typically last 5 to 10 years if kept in a cool, dry place. I found them perfect for an adult just starting out with a drawer full of spare batteries for emergencies.
What devices are these batteries recommended for?
Maxell specifically lists calculators as a recommended use, but I also used them in watches, key fobs, and small laser pointers. The CR2016 is a common size for many small electronics, so just confirm the battery compartment matches before buying. Avoid using them in high-drain devices like digital cameras, as the 80mAh capacity is too low for that.
My Final Verdict
After months of testing the Maxell Micro Lithium Cell Battery CR2016 5-pack in watches, calculators, and key fobs, I am confident these are a solid choice for anyone needing reliable 3V power. The 80mAh capacity and steady voltage delivery lived up to the claims, and the long shelf life means I can keep spares handy. I would recommend this pack to anyone who values brand trust and consistent performance over the cheapest option.
The main limitation is they are single-use, so you cannot recharge them, but for the price of a coffee per battery, I think the convenience and Maxell’s reputation make them worth it. If you need a dependable CR2016 that just works, this is the pack I would grab again.
