My Buying Guides on Key Fob Battery Cr1620
My Quick Take on the CR1620 Key Fob Battery
When I shop for a CR1620 battery for my key fob, I look for one thing first: reliability. A dead key fob battery can leave me locked out or stuck at the worst possible time, so I prefer a battery that offers steady power, a good shelf life, and trusted brand quality.
What the CR1620 Battery Is
The CR1620 is a small 3V lithium coin battery. I usually find it used in key fobs, car remotes, calculators, watches, fitness devices, and other compact electronics. The “1620” refers to its size, which is important because even a slight mismatch can stop the device from working properly.
How I Check Compatibility
Before I buy, I always confirm that my key fob actually uses a CR1620. I check the old battery, the owner’s manual, or the battery compartment label. If I am unsure, I avoid guessing, because CR1616, CR2016, and CR2032 batteries may look similar but are not interchangeable in many devices.
What I Look for in a Good CR1620 Battery

- Packaging: I like sealed packaging because it helps preserve freshness.
My Tips for Choosing Between Brands
In my experience, premium brands often last longer and perform more consistently in key fobs. That said, I do not always buy the most expensive option. I compare reviews, expiration dates, and seller reputation. If a battery is cheap but has poor feedback or an unclear manufacturing date, I usually skip it.
How I Know When It Is Time to Replace It
My key fob usually gives me a few warning signs before the battery dies completely. The range gets shorter, I have to press buttons more than once, or the fob works only sometimes. When I notice these signs, I replace the battery right away instead of waiting for total failure.
Battery Life Expectations
The lifespan of a CR1620 battery depends on how often I use the key fob and the quality of the battery itself. In general, I expect a good battery to last a long time in a low-drain device like a remote. If I use my fob frequently, I may need to replace it sooner.
My Buying Checklist
- Confirm the device uses CR1620
- Choose a trusted brand
- Check the expiration date
- Buy from a reliable seller
- Keep a spare battery at home
How I Store Spare Batteries
I store my spare CR1620 batteries in a cool, dry place and keep them in their original packaging until I need them. I avoid tossing loose batteries into a drawer, because that can damage them or cause them to discharge faster.
Final Thoughts
