This small but powerful battery provides the perfect amount of energy needed to operate the fob’s functions, like locking and unlocking the doors remotely.

My Buying Guides on Cr1620 Battery For Car Key Fob
When it comes to replacing the battery in my car key fob, I’ve learned that choosing the right CR1620 battery is essential for reliable performance. Here’s what I consider before making a purchase, based on my personal experience.
Understanding the CR1620 Battery
The CR1620 is a 3-volt lithium coin cell battery commonly used in car key fobs, watches, and small electronics. I always check my key fob’s manual or the existing battery to confirm the exact model number to avoid any compatibility issues.
Checking Compatibility with My Car Key Fob
Not all key fobs use the same battery type, so I make sure the CR1620 is the recommended battery for my specific car make and model. Sometimes, manufacturers use similar batteries like CR1616 or CR1632, so double-checking prevents me from buying the wrong one.
Battery Life and Performance
I look for batteries that offer a long shelf life (usually 3-5 years) and consistent voltage output. I’ve found that reputable brands tend to last longer and perform better, which saves me the hassle of frequent replacements.
Brand and Quality Considerations
Over time, I’ve learned that not all CR1620 batteries are created equal. I prefer buying from well-known brands like Panasonic, Energizer, or Sony because their batteries are reliable and less likely to leak or fail prematurely.
Price vs. Value
While it’s tempting to buy the cheapest option, I focus more on value. A slightly higher price for a quality battery is worth it since it keeps my key fob working smoothly for a longer time. Bulk packs are a good deal if I need multiple batteries or want to keep spares handy.
Where to Buy
I usually purchase CR1620 batteries from trusted electronics stores or reputable online retailers. This way, I avoid counterfeit products and ensure I’m getting genuine batteries.
How to Replace the Battery Safely
Replacing the battery in my car key fob is straightforward but requires care. I use a small screwdriver or a coin to open the fob, note the battery orientation, and avoid touching the battery surface with my fingers to prevent corrosion.
Environmental Considerations
I make sure to dispose of old batteries properly at a recycling center, as lithium batteries can be harmful to the environment. Some stores offer battery recycling programs, which I find convenient.
Final Thoughts
Choosing the right CR1620 battery for my car key fob ensures my vehicle’s remote functions work reliably. By paying attention to compatibility, brand quality, and proper handling, I’ve avoided many common issues and kept my key fob in top shape.
