Review: Reliable, Long-Lasting Power for Small Electronics Rating: ★★★★★ (5/5) - I’ve used the VARTA CR2450 lithium button cells in various devices—kitchen scales, remote sensors, and smart tags—and they’ve consistently delivered strong, stable power. The 2-pack is convenient for replacements, and the packaging is secure but easy to open. 👍 Pros: • Long shelf life – holds charge well even after months in storage. • Consistent voltage – no drop-offs or early failures in my devices. • Trusted brand – VARTA has a solid reputation for quality and reliability. • Secure packaging – tamper-proof yet easy to open without scissors. • Mercury-free – safer for the environment and compliant with EU regulations. 👎 Cons: • Slightly pricier than generic alternatives—but worth it for peace of mind. • Limited to 2-pack – bulk buyers may want larger quantity options. 💡 Tips: • Ideal for devices like car key fobs, fitness trackers, and digital thermometers. • Store extras in a cool, dry place to maximize shelf life. • Always check your device’s polarity before inserting. If you need dependable CR2450 batteries for critical electronics, this VARTA 2-pack is a smart, worry-free choice.
Review: Highly recommended to others. - Bought these to replace failing batteries in my car keys. They are identical to the original batteries that each key contained, same manufacturer / spec - and the original ones lasted for many years. Always recommended to go with a premium battery over lower cost generic brands that you've never heard of - firstly, they always work as described, secondly they are manufactured to an excellent standard, and thirdly they last so much longer. It's worth paying the extra money for these benefits.

## Questions & Answers

**Q: Mine are made in China, not Germany. Are they fakes?**
A: They are not fake. They are just made with slave labour.

**Q: how do i fit the varta 4230 to my watchman oil sensor - the one actually in the tank?**
A: Unscrew by hand the black sensor on the top of the tank, take it back to the plug in reader inside the house, turn off plug in reader. On the sensor undo 4 screws and gentle pull apart you will see the batteries, remember the way the old batteries go in (which way up). Replace and put together. Hold sensor and the reader together and turn on, you will see a black dot on the sensor touch that against the plug-in-reader until you get a connection. screw it back on the top of your oil tank. PS if it's raining cover the hole up on the top of your oil tank whilst your refitting the batteries. Hope that helps.

**Q: could you advise use by date?**
A: Sorry, I just installed mine, I didn't check to see if there was one. That was about a year ago in a Roberts clock radio about 2003 vintage that came from a charity shop. It keeps the digital clock going when not plugged in. Still working
