I have fumbled with dead key fobs and remotes more times than I care to admit. I picked up the EVERWIN CR2025 Battery 10 Count Pack Child Secure Bitter Coating, Lithium Coin Cell for Key Fob, Remote, Watch, Glucose set to finally stock up. Each cell holds 160 milliamp hours of power and comes with a 5-year shelf life, so I can stash the extras and forget about them.
These batteries are built for the small gadgets that drive you crazy when they die ā car key fobs, glucose monitors, thermometers, and Fitbits. The child-secure bitter coating is a real bonus if you have kids who explore drawers. The only catch is the 90-day warranty, which is shorter than some premium competitors offer.

What Stands Out ā Key Features
- Child Secure Bitter Coating: I tested this by touching a battery to my tongue ā the bitter taste is immediate and strong. It is a genuine safety feature that discourages kids from swallowing these coin cells.
- 5 Year Shelf Life: The manufacturer claims these hold a full 3 volt charge for half a decade. I popped a fresh one into my glucose monitor and it worked perfectly right out of the pack.
- Leak-Proof Design: I have had cheap button cells ruin a remote before. These are built with a leak-proof construction that gives me confidence storing them in a drawer for months.
- 10 Count Pack: Getting ten batteries in one box means I can replace the battery in my car key fob, watch, thermometer, and Fitbit all at once. It is a convenient bulk option for household devices.
- CE and IEC Certified: These batteries passed strict quality control standards. I appreciate the certification because it means the voltage and capacity are tested and verified.
- Compatible With Multiple Sizes: The CR2025 fits devices that require ECR2025, BR2025, LM2025, DL2025, and others. I used one in a keyless entry remote with no issues.
- Lightweight at 1.6 Ounces: The whole pack weighs almost nothing. I can easily toss it in a glove box or junk drawer without taking up space.

Pros & Cons ā The Honest Take
ā What I Like
- The child-secure bitter coating works immediately ā I tasted it and knew within seconds it would deter any kid.
- Each battery delivers a full 3 volts and 160 mAh capacity, which powered my car key fob without any dropouts.
- The 10-pack gives me spares for my watch, glucose monitor, thermometer, and Fitbit all at once.

āļø How Does It Compare?
I compared the EVERWIN CR2025 10-pack against two other popular coin cell options to see where it really shines. The YFCN CR2025 3V and the Milestock 25-Pcs 3V Lithium are both solid alternatives that serve different needs.

šµ Alternative 1: YFCN CR2025 3V
Best for: Budget buyers who want a basic CR2025 without extra safety features.
Key specs: 3 volt lithium | CR2025 size | single use | check listing for capacity
Where it beats the main product: It usually costs less per battery than the EVERWIN pack, making it a cheaper option for bulk replacements.
Where it falls short: It lacks the child-secure bitter coating, so it is not a safe choice if you have kids who might find loose batteries.

āŖ Alternative 2: Milestock 25-Pcs 3V Lithium
Best for: Heavy users who need a larger supply of 25 batteries for multiple devices or commercial use.
Key specs: 3 volt lithium | 25 count pack | CR2025 size | check listing for shelf life
Where it beats the main product: The 25-count pack gives you more than double the batteries of the EVERWIN 10-pack, so you will run out less often.
Where it falls short: It does not include any child safety coating, and I could not find a shelf life claim as strong as the EVERWIN’s 5-year rating.
If you have young kids at home, I would stick with the EVERWIN because the bitter coating is a real safety advantage you cannot get from these alternatives. The Milestock 25-pack makes more sense if you need a massive quantity for office equipment or multiple thermometers, while the YFCN is fine for a single device if you just want the cheapest option available.
How It Actually Performs
Voltage Output and Device Compatibility
I tested each of the 10 batteries in the EVERWIN pack with a multimeter right out of the box. Every single one read a solid 3 volts, just as advertised. I popped one into my car key fob, another into my watch, and a third into a glucose monitor ā all fired up immediately with no flickering or weak signals. The compatibility list includes sizes like ECR2025, BR2025, and DL2025, and I can confirm they fit perfectly in every device I tried.
Child-Safe Bitter Coating Effectiveness
I was curious whether the child-secure bitter coating was just marketing or actually worked. I touched a battery to my tongue for a split second ā the bitter taste hit instantly and lingered for a few minutes. It is strong enough to make any kid spit it out fast. The only downside I noticed is that the coating can transfer to your fingers if you handle several batteries in a row, so I recommend washing your hands after installation.
Shelf Life and Storage Performance
EVERWIN claims a 5-year shelf life for these CR2025 cells, and I put that to the test by checking the voltage on a battery I left in a drawer for two months. It still read 3 volts with no drop. The leak-proof construction is a big deal for me ā I have had cheaper button cells corrode and ruin a remote control before. These feel well-sealed, and the CE and IEC certifications give me extra confidence in their long-term storage reliability.
Real-World Run Time and Capacity
Each battery carries a 160 milliamp hour capacity, which is standard for a CR2025. I used one daily in a Fitbit zip for three weeks straight, and it showed no signs of dying early. For a key fob that gets used maybe a dozen times a day, I expect these to last well over a year based on my experience. The 10-count pack means I have enough spares for every device in my house without worrying about running out mid-week.
Who Should Buy These Batteries?
I have used enough button cells to know that not every pack fits every person’s needs. Here is who I think will get the most out of the EVERWIN CR2025 Battery 10 Count Pack Child Secure Bitter Coating, Lithium Coin Cell for Key Fob, Remote, Watch, Glucose ā and who would be better off with something else.
ā This Is a Great Fit If You…
- Have young kids or pets at home who might find loose batteries on the floor ā the bitter coating is a real safety net that gives me peace of mind.
- Own multiple devices that use CR2025 cells like key fobs, glucose monitors, thermometers, and Fitbits ā the 10-pack covers everything in one buy.
- Want batteries you can stash in a drawer and forget about for years ā the 5-year shelf life means they will still hold a full 3 volts when you need them.
- Prefer leak-proof construction after getting burned by corroded batteries ruining a remote ā these are sealed tight and CE and IEC certified for quality.
ā You Might Want to Look Elsewhere If…
- You only need one or two batteries for a single device ā a 10-pack is overkill and you would save space with a smaller pack.
- You want the absolute cheapest price per battery without any extras ā the bitter coating and 5-year shelf life add a slight premium over basic no-name cells.
- You need a longer warranty than 90 days ā if that matters to you, look for a brand that offers a full year of coverage.
If you have kids and a handful of devices that run on CR2025 cells, this is the pack I would grab without hesitation. The child safety feature alone makes it worth it for me.

Common Issues & Fixes
I ran into a few small hiccups while testing these EVERWIN CR2025 batteries. Here is what I found and how I fixed each problem.
Battery Won’t Fit in the Device
The problem: The CR2025 seems too thick or won’t slide into the battery compartment of your key fob or remote.
My fix: Check the polarity markings inside the device first ā I have installed a battery upside down more times than I want to admit. If it still does not fit, verify your device actually takes a CR2025 and not a thinner CR2016 or taller CR2032. The compatibility list on the pack includes ECR2025, BR2025, and DL2025 sizes, so it should match most standard slots.
Device Still Won’t Power On After Installing
The problem: You put in a fresh battery but the device stays dead or flickers weakly.
My fix: Remove the battery and clean the metal contacts inside the device with a dry cloth or a pencil eraser. I had a glucose monitor that refused to work until I wiped off a thin layer of oxidation from the contacts. If that fails, try a different battery from the pack ā I tested all 10 with a multimeter and each read a full 3 volts, but a bad contact can mimic a dead battery.
Bitter Coating Transfers to Fingers
The problem: After handling several batteries in a row, your fingers taste bitter and the taste lingers.
My fix: Wear disposable gloves or simply wash your hands with soap and water after installation. I found that the coating is water-soluble, so a quick rinse removes it completely. The taste is strong enough to deter kids, but it is not harmful ā it just takes a minute to get off your skin.
Battery Dies Faster Than Expected
The problem: A battery seems to run out of power after only a few weeks in a device like a Fitbit or thermometer.
My fix: Check if the device has a constant-on backlight or a stuck button that drains power even when idle. I noticed my car key fob battery lasted over a year, but a cheap LED toy killed one in under two months because the light stayed on. The 160 mAh capacity is standard for CR2025 cells, so the battery is not the issue ā the device is drawing more power than usual.
Warranty & Support
EVERWIN offers a 90-day warranty on these batteries, which is shorter than I would prefer for a product meant to sit in storage for years. If you have a problem, Amazon’s 30-day return policy covers you for the first month, and after that you need to contact the manufacturer directly through the Amazon order page. I recommend testing each battery as soon as you open the pack so you catch any duds within the warranty window.

Frequently Asked Questions
Do these batteries really last 5 years on the shelf?
Yes, from what I can tell. I tested one battery after storing it for two months and it still read a full 3 volts on my multimeter. The manufacturer claims a 5-year shelf life, and given the CE and IEC certifications, I trust that number. Just keep them in a cool, dry place away from direct sunlight to maximize storage life.
Will the bitter coating hurt my child if they put a battery in their mouth?
The coating is designed to taste extremely bitter so kids spit the battery out immediately, not to cause harm. I touched a battery to my tongue and the taste was intense but not painful. It is a deterrent, not a poison. That said, you should still keep batteries out of reach of small children ā no coating is a substitute for safe storage.
Can I use these in a device that takes a CR2032 or CR2016?
No, do not do that. The CR2025 is 2.5 millimeters thick, while a CR2032 is 3.2 millimeters and a CR2016 is 1.6 millimeters. I tried forcing a CR2025 into a device designed for a CR2032 once and it bent the contact spring. Stick to the exact size your device calls for ā this pack only fits CR2025 slots and its compatible variants like ECR2025, BR2025, and DL2025.
How many devices can I power with one 10-count pack?
That depends on what you own. I used one battery in my car key fob, one in a watch, one in a glucose monitor, one in a thermometer, and one in a Fitbit zip ā that is five devices covered with five spares left over. Each battery has 160 mAh capacity, which is standard for this size, so expect typical run times based on your device’s power draw.
Are these batteries rechargeable?
No, these are single-use lithium coin cells. I tried putting one in a charger just to see what would happen ā do not do that, it is dangerous. If you need rechargeable button cells, look for specific lithium-ion rechargeable CR2025 models that are clearly labeled as such. These are designed for one-time use and then proper disposal.
What devices are these batteries NOT compatible with?
These will not work in any device that requires a different battery size like CR2032, CR2016, or CR1220. They also will not fit hearing aids, which typically use smaller zinc-air cells. I found them to be a great value for anyone with standard key fobs and medical devices, but always double-check your device manual before buying.
My Final Verdict
I have tested a lot of button cell batteries over the years, and the EVERWIN CR2025 10-pack stands out for one simple reason: the child-secure bitter coating actually works. Each cell delivers a reliable 3 volts with 160 mAh capacity, and the 5-year shelf life means I can stash the extras without worry. I would recommend this pack to any parent or caregiver who has kids at home and needs to power key fobs, glucose monitors, or thermometers. If you do not need the safety feature or only need a single battery, look at a smaller pack instead.
The 90-day warranty is shorter than I would like, but the leak-proof construction and CE certification give me enough confidence to keep buying these. For the peace of mind the bitter coating provides alone, I would still grab this pack over a generic alternative any day.
