CR1620 Battery Review for Key Fob Trackers by CELEWELL High Performance

Description

Positive Features of the CELEWELL CR1620 Battery Pack

After trying out the CELEWELL CR1620 5 Pack for Key Fob Tracker 70mAh 3V Lithium Battery, I noticed several standout benefits that make these lithium batteries worth considering. The most impressive aspect is their high capacity; each battery delivers a firm 70mAh, which is quite robust for this size. Unlike generic batteries that sometimes fall short or even leak capacity, these maintained consistent power during my tests. The promise of no leakage for 5 years, backed by certifications like ISO9001 and UL, gives peace of mind that these batteries won’t cause damage to delicate electronics such as car key fobs or watches. Plus, the brand warranty from CELEWELL adds an extra layer of trust, showing the company stands behind its quality claims.

The pack’s multiple compatibility is another asset. These batteries fit a wide range of devices beyond just key fobs—watches from brands like Swatch and Fossil, 3D glasses, calculators, and even computer motherboards. I personally swapped one into my Mazda 3 key fob, and it worked flawlessly without any hiccups or lag in signal strength. This versatility means you don’t have to buy different batteries for every little gadget, which is handy and saves space in my drawer.

Highlights of the CELEWELL CR1620 pack include:

• High and reliable 70mAh capacity ensuring longer life
• Certified safety standards preventing leakage or performance issues
• Wide compatibility covering numerous small electronics
• Five-year warranty offering confidence in the product’s durability

Limitations to Keep in Mind

While these batteries performed well overall, a few drawbacks did surface during my daily use. First, the packaging could be improved; there’s no bulk option, and with five batteries per pack, it’s easy to misplace them if you’re not careful. Also, the batteries are quite slim at 0.28 inches thick, which is expected, but some devices might have tighter compartments making installation a bit fiddly.

Although the shelf life is advertised as five years, I wonder how they hold up under extreme temperature fluctuations, as I didn’t test that specifically. A few users online mentioned that in colder climates, lithium coin batteries can discharge faster, so this might be something to watch out for if you live in such areas.

Potential areas for improvement include:

• Packaging that better secures batteries to prevent loss
• More detailed guidance on temperature performance
• Bulk purchasing options for frequent users or households

Design and Build Quality

The design of these batteries is quite standard for the CR1620 form factor, measuring 16mm in diameter and 2mm in thickness, which fits perfectly in most devices requiring this size. The weight of 0.32 ounces is negligible, as expected for coin cells, and the overall build feels sturdy with no visible defects.

I appreciated the clear manufacturer markings on each battery, including the production and warranty dates, which is a nice touch often missing in budget brands. This transparency helped me track the freshness of the batteries, ensuring I always used the newest ones first. The slim profile makes them easy to slide into slim key fob compartments or watch battery slots without forcing.

Performance and Reliability in Everyday Use

Testing these batteries in a variety of devices revealed consistent voltage output, which kept my remote keyless entry systems responsive and watches ticking smoothly. The 3V lithium polymer chemistry means stable power delivery, and I never experienced any sudden drops or device shutdowns related to battery failures.

One interesting observation came from my nephew, who uses 3D glasses for gaming. After swapping in one of the batteries, he noticed no lag or flickering, which can sometimes occur with weaker batteries. The reliability across different devices—from calculators to LED flashlights—makes this pack a reliable go-to for small electronics.

Comparing to Other Options on the Market

Among competing products, I’ve tried other CR1620 batteries like Energizer and Panasonic. While those brands offer similar voltages, CELEWELL’s batteries stood out in terms of capacity and warranty. Some competitors claim high capacity but fall short in real-world tests, and their warranties tend to be shorter.

However, the CELEWELL pack lacks the premium packaging and brand recognition of these household names, which might deter some buyers. Still, for the price and performance, this lithium battery pack holds its own, especially for those seeking long-lasting, leak-proof batteries for key fobs and watches.

Here’s how it compares:

• CELEWELL offers higher capacity and longer warranty than many rivals
• Some competitors provide more luxurious packaging and bulk options
• CELEWELL batteries excel in safety certifications like RoHS and UN38.3, which aren’t always guaranteed with cheaper brands

Worth the Investment?

Examining the price to quality ratio, this battery pack delivers solid value. You’re paying for a high-capacity lithium polymer battery that promises up to five years of safe use without leakage. For my needs, replacing batteries in frequently used devices, this pack was a cost-effective choice.

While it isn’t the cheapest option, the assurance of no leaks and consistent performance justifies the investment. Cheaper alternatives might save a few dollars upfront but could risk damaging your devices or dying prematurely. For anyone who depends on reliable power for key fobs, watches, or electronics, this pack offers a smart balance of durability and safety.

User Experience and Practical Observations

My coworkers, who also tested these batteries in various devices, shared similar sentiments—no issues with fit, power, or safety. One colleague appreciated how the batteries didn’t corrode or leak after months of use, a common problem with older or off-brand lithium cells.

At home, my kids swapped these batteries into their calculators and LED flashlights, and all devices performed without hiccups. The ease of installation and consistent energy output made these batteries a favorite. The only annoyance was occasionally misplacing the slim batteries, which are easy to lose if not stored carefully.

Summary of Advantages and Drawbacks

Positive Features:

• Long-lasting 70mAh capacity ensures durable power
• Five-year warranty and extensive safety certifications
• Compatible with a wide range of devices from watches to key fobs
• Clear manufacturing and expiry date labeling on each battery card

Negative Attributes:

• Packaging could be improved to better secure batteries

Testing the CELEWELL CR1620 battery pack gave me confidence that it’s a reliable, high-quality option for anyone needing dependable power in small devices. The balance of safety, capacity, and warranty coverage makes it competitive against other brands, though some minor improvements could enhance the user experience further.
