Great long lasting battery
These batteries last so much longer than other brands, we have been replacing old batteries with Energizer ones when they need replacing.

Q: Will this coin cell replace the Energizer E303804100 battery?
A: Yes. Energizer E303804100 is a CR2025 2 pack. Match the CR2025 code in your device before buying, because coin cells that look alike can differ in thickness and may not fit or make proper contact.
Q: How do I know a CR2025 will fit my device?
A: A CR2025 fits only devices designed for that exact code. This battery is 20mm in diameter and 2.5mm thick, so another coin cell is not close enough just because it looks similar in the tray.
Q: Can I use this battery in my car key fob?
A: Yes, if the fob battery tray or manual specifies CR2025. Many remotes use similar looking coin cells with different thicknesses, so check the code on the old battery rather than matching by shape alone.
Q: Are CR2025 coin batteries interchangeable with other coin cell sizes?
A: No. Energizer CR2025 should replace a battery marked CR2025, not a different code. Coin cells can share the same round shape but still differ in thickness, which can stop the tray closing or prevent solid contact.
Q: Does this battery suit devices kept in a car?
A: Yes. Energizer CR2025 is designed to power small electronics in extreme temperatures, which suits items such as key fobs kept in a bag or car. It is still a single-use battery, so it needs full replacement when flat.
