My Buying Guides on CR1620 Battery For Car Key Fob
When my car key fob started acting up, I quickly realized that the battery was the culprit. After some research and personal experience, I put together this buying guide for anyone looking to purchase a CR1620 battery for their car key fob. Here’s what I learned along the way.
Understanding the CR1620 Battery
First things first, I had to understand what a CR1620 battery is. It’s a lithium coin cell battery that’s commonly used in various devices, including car key fobs, watches, and calculators. What I found helpful was knowing that the “CR” stands for lithium chemistry and “1620” indicates its size – 16mm in diameter and 2.0mm in thickness.
Compatibility Check
Before I made my purchase, I made sure to check if the CR1620 was compatible with my key fob. Most manufacturers provide a list of compatible batteries in the user manual or on their websites. I recommend looking for a compatibility list specific to your car model to avoid any mismatches.
Brand Matters
When I went shopping, I noticed a plethora of brands offering CR1620 batteries. I learned that not all batteries are created equal. Some brands like Energizer, Duracell, and Panasonic have a reputation for reliability and longevity. I personally opted for Energizer because I’ve had good experiences with their products in the past.
Battery Life
One thing that caught my attention was the battery life. Typically, a CR1620 battery can last anywhere from 1 to 3 years, depending on usage. I decided to check reviews and product descriptions to find batteries that offered longer life spans. It turned out that batteries with a higher mAh rating tend to last longer.
Price Point
I found that prices for CR1620 batteries can vary significantly. I came across single batteries priced around $2 to $5, while multi-packs offered better value, usually at $8 to $15. I ended up purchasing a multi-pack since it provided a backup for the future and saved me money in the long run.
Where to Buy
Deciding where to buy my CR1620 battery was another important step. I explored various options, including local auto parts stores, pharmacies, and online retailers like Amazon. I appreciated the convenience of online shopping, especially when I found a trusted seller with good reviews.
Checking Expiration Dates
One tip I picked up was to always check the expiration date before purchasing. I learned the hard way that batteries can lose their charge over time, even if they’re sealed. So, when I found fresh stock with a long shelf life, I felt more confident in my choice.
Installation Tips
Once I had my new CR1620 battery in hand, I realized I needed to know how to replace it properly. Most key fobs can be opened with a small screwdriver, and I watched a few quick tutorial videos to ensure I didn’t damage anything during the process. It’s always good to be prepared!

By checking compatibility, choosing a reputable brand, considering battery life, and shopping wisely, I felt confident in my purchase. I hope this guide helps you as much as it helped me!
