On a previous Car I ran a 240v Extension Reel into the Boot and connected with the standard Ctek Lead, the Boot Seal allowed for the thickness of the 240v Flex. **Q: Is this compatible with the cs free charger to connect eyelets to the battery terminal? the only leads with the cs free are croc clips.** A: Hi there, I am afraid I cannot give you a 100% accurate answer. I don't know what the "cs free charger" is. I bought the CTEK battery charger and wanted the extension cable so that I could reach the car from a wall socket. My CTEK came with both a croc clips cable and an eyelets cable. Both of these short cables use the strangely shaped orange connector to connect the the CTEK. Therefore if you have the CTEK you can use either the eyelets or croc clips cable. I actually got my garage to fit the eyelet cable to the battery (mainly because my car has the battery underneath a cowling in the engine compartment and it is very awkward to get at the battery terminals). The car was being serviced and my garage didn't even charge me to fix the eyelets to the battery and they strapped the strange orange connector plug to some pipework under the car bonnet. It works great and with the extension lead I just raise the bonnet and hook up the CTEK within a couple of minutes. The CTEK has been a life saver for me. My car doesn't get used a great deal and I can now keep the battery topped up all the time (usually I hook up the CTEK about once every 8-9 days. I know that's not a direct answer but if you do own the CTEK charger you can use this extension cable and choose either the croc clips or eyelets cable that comes with the CTEK. Without the CTEK charger and the unique orange connector plug that is fitted on the cable that comes out of the charger then this extension cable would not be compatible (unless you can get the unique orange connector with other chargers but I haven't seen any, I think it's a custom CTEK fitting). Hope that helps. **Q: is this product waterproof?** A: I would say its more water resistant when connected rather than waterproof. I have used mine many times over past 5 years outside and its been fine. I cover the connector and keep it off the ground with a small plastic box or plant pot and them cover box with another bigger box. Also means people wont trip over it. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good but rather rigid lead *by on Reviewed in the United Kingdom 17 February 2026* Does the job, as it avoids having to have the charger inbthe engine bay. But the quality of the lead itself is disappointing; for the price I expected the lead to be a lot more flexible. ### ⭐⭐⭐⭐⭐ Good price and quality *by on Reviewed in the United Kingdom 29 June 2026* This was very helpful to extend my ctek ### ⭐⭐⭐⭐⭐ Delivered quickly and works as advertised *by on Reviewed in the United Kingdom 6 June 2026* As advertised ## Frequently Bought Together - CTEK (56-304) Comfort Connect Extension Cable, 8.2 Feet - CTEK - 40-206 MXS 5.0 Fully Automatic 4.3 amp Battery Charger and Maintainer 12V - CTEK (56-870) Comfort Indicator Cig Plug --- ## 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.pt/products/48102709-ctek-56-304-connect-2-5m-extension-extend-the-range](https://www.desertcart.pt/products/48102709-ctek-56-304-connect-2-5m-extension-extend-the-range) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-03*
