CTEK Lithium XS UK Vehicle Battery Charger 40 – 003

CTEK Lithium XS UK Vehicle Battery Charger 40-003 – The Smart Choice for LiFePO4 Batteries

When it comes to maintaining and charging lithium (LiFePO4) batteries, the CTEK Lithium XS 40-003 stands out as a reliable and efficient solution. Designed specifically for 12V lithium iron phosphate (LiFePO4) batteries, this charger delivers intelligent charging, safety features, and ease of use—making it an essential tool for modern vehicle owners.

Key Features & Performance

1. Optimised for LiFePO4 Batteries
   Unlike standard lead-acid battery chargers, the CTEK Lithium XS is engineered exclusively for 12V lithium batteries (LiFePO4). It ensures a precise charging cycle, preventing overcharging while maximising battery life.

2. 5A Charging Current & Wide Compatibility
   With a 5A output, this charger efficiently charges batteries from 5Ah to 60Ah and can maintain larger batteries up to 120Ah. Whether you own a high-performance sports car, a hybrid, or an electric vehicle with a lithium auxiliary battery, this charger delivers consistent power.

3. Automatic Wake-Up Function
   Many lithium batteries feature low-voltage protection that disconnects the battery when voltage drops too low. The CTEK Lithium XS automatically detects and reactivates these batteries, eliminating the need for manual intervention.

4. 8-Stage Smart Charging
   The intelligent charging process includes:

   • Desulphation (for slight lead-acid compatibility)
   • Soft Start (prevents power surges)
   • Bulk Charge (fast charging)
   • Absorption (optimises charge levels)
   • Lithium Analysis (monitors battery health)
   • Lithium Recondition (maintains performance)
   • Float Mode (keeps battery at ideal voltage)
   • Pulse Maintenance (prevents self-discharge)

5. Durable & Safe Design

   • IP65-rated (splash-proof and dustproof)
   • Reverse polarity protection (prevents damage from incorrect connections)
   • Includes both clamps and eyelet connectors (for hard-to-reach batteries)

What Customers Say

Owners of high-end vehicles, including Porsche Taycan drivers, praise the CTEK Lithium XS for its reliability. One reviewer noted:

“This is the charger needed for the 12V battery in the frunk of a Porsche Taycan. High-quality product that does the job perfectly.”

Another user highlighted its ease of use:

“Just connect to your battery, plug in, and away it goes. Perfect for LiFePO4 batteries with built-in battery management systems.”

Final Verdict

The CTEK Lithium XS 40-003 is a premium charger that ensures safe, efficient, and hassle-free charging for lithium batteries. Its smart technology, robust build, and automatic features make it a must-have for anyone with a modern vehicle.

For hybrid, electric, or performance cars with lithium auxiliary batteries, this charger provides peace of mind—keeping your battery in optimal condition for years to come.
