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: 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.

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.

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. ### ⭐⭐⭐⭐ Do not fit smart things sensors *by on Reviewed in the United Kingdom 9 March 2019* Batteries are great but they DO NOT FIT the Smart things sensors so do not buy for them. ## Frequently Bought Together - VARTA Batteries Electronics CR2450 Lithium button cell battery 2-pack, Button cells in original blister pack of 2 - DURACELL CR123 (2 Pack) High Power Lithium Battery 3V (CR123A / CR17345) – Long life guarantee – For Cameras, Flashlights, Smoke Detectors & Small Devices – 10–Year Storage Guarantee - Leak Prevention --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/48124566-varta-coin-cell-batteries-cr2450-pack-of-2-lithium-coin](https://www.desertcart.tn/products/48124566-varta-coin-cell-batteries-cr2450-pack-of-2-lithium-coin) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-28*
