My Buying Guides on Cr1620 Battery For Car Key Fob
When it comes to replacing the battery in my car key fob, choosing the right CR1620 battery is crucial. Over time, I’ve learned a few important things that make the process smoother and ensure my key fob works reliably. Here’s what I consider before buying a CR1620 battery for my car key fob.
Understanding the CR1620 Battery
First, I make sure I know exactly what a CR1620 battery is. It’s a small, round lithium coin cell battery, typically 16mm in diameter and 2.0mm thick. It’s commonly used in car key fobs, watches, and small electronics. Knowing the size and type helps me avoid confusion with similar batteries like CR1632 or CR2016.
Check My Car Key Fob Specifications
Before ordering, I always check the user manual or the inside of my key fob to confirm that CR1620 is the correct battery type. Sometimes, key fob models vary, and using the wrong battery can cause problems or damage. If the original battery is still inside, I note the exact model number printed on it.
Quality and Brand Matter
I’ve found that not all CR1620 batteries are created equal. I prefer buying from reputable brands like Panasonic, Energizer, or Sony because they usually last longer and perform better. Cheaper off-brand batteries might save money upfront, but they often die faster or leak, which can damage my key fob.
Check Battery Expiry Date
When purchasing, I always look at the expiry or manufacturing date on the package. Fresh batteries last longer, so I avoid those that have been sitting on shelves for years. A battery that is too old might not hold charge well, even if unused.
Buy in Multipacks for Convenience
Since I know I will eventually need replacements again, I often buy CR1620 batteries in multi-packs. It’s more economical and ensures I have a backup when my key fob battery finally runs out. Just make sure to store extras in a cool, dry place.
Consider Battery Capacity (mAh)
Though many CR1620 batteries are similar, checking the mAh rating (milliamp-hours) can give me an idea of how long the battery might last. Higher mAh means longer life. If available, I choose batteries with a slightly higher capacity for better longevity.
Where to Buy
I usually buy these batteries from trusted electronics stores or online marketplaces with good reviews. Reading customer feedback helps me avoid counterfeit or low-quality products. Sometimes, official car dealerships sell the exact battery, but they tend to be pricier.
Proper Installation Tips
Once I have the battery, I carefully open my key fob using the right tools to avoid damage. I handle the new battery with clean, dry hands or gloves to prevent oils or moisture from affecting it. After replacement, I test the key fob functions immediately to confirm everything works perfectly.
Disposal of Old Batteries
I always make sure to dispose of my old CR1620 batteries responsibly by taking them to a battery recycling center. These batteries contain lithium and other materials that shouldn’t be thrown in regular trash.

By following these points, I’ve made replacing my car key fob battery hassle-free and reliable. I hope my experience helps you find the best CR1620 battery for your key fob too!
