CTEK Offers other excellent chargers for other type batteries. The short answer is no. **Q: Why does this "lithium charger" have a "desulphation" charging phase?** A: Good catch :) the diagram on this page is incorrect for this charger. Go pick up the manual (its online). Step 1 is ACCEPT. I've been very happy with mine, 2+ years ownership. **Q: Can i leave it on all winter or should i remove it from time to time? i have an f80 m3 as another individual. thanks!** A: I keep mine hooked up all the time when the vehicle is not in use. I have mine for about two years without any issues. The CTEK is build to keep battery at optimum level, never over charging, but maintaining. You shouldn't have any issues leaving hooked during the winter. **Q: Do i have to buy multiple chargers for acid,agm and lithium?** A: You can use same charger for acid and agm but lithium charger is only for lithium batteries ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by K***R on December 30, 2025* ### ⭐⭐⭐⭐⭐ Review *by B***T on January 13, 2026* ### ⭐⭐⭐⭐⭐ Review *by R***S on December 3, 2025* ## Frequently Bought Together - CTEK 56-926 Lithium US | Fully Automatic Lithium Ion Phosphate LiFePO4 Battery Charger | 5.0Ah - 60Ah | Maintenance Charging up to 120Ah - CTEK (56-304) Comfort Connect Extension Cable, 8.2 Feet - CTEK Connect CIG Plug, Permanent Connection for Hard-to-Reach Batteries, Easy Connection to Your CTEK Battery Charger Using The Vehicle 12V Accessory Sockets, for Cars, Motorcycles & Other Vehicles --- ## 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.co.uk/products/6838915-ctek-56-926-lithium-us-fully-automatic-lithium-ion-phosphate](https://www.desertcart.co.uk/products/6838915-ctek-56-926-lithium-us-fully-automatic-lithium-ion-phosphate) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-25*
