More and more bikers are now opting for lithium batteries. The main reason is the great reduction in weight as lithium batteries not only weigh less but also occupy less space.

With Lithium (12V LiFePO4) batteries being more regularly used in high-performance vehicles, and being installed as aftermarket products in powersport and other leisure vehicles, we have seen a greater demand for lithium battery chargers.

CTEK Lithium XS

We would not recommend that you charge a Lithium (12V LiFePO4) battery with a lead-acid battery charger. In CTEK chargers, for example, trigger levels within the algorithms for Lithium and lead-acid chargers are very different, this is to ensure each technology is charged as quickly and safely as possible. Not using the correct charger will impair the batteries performance and service life. It is also worth noting that the BMS in a Lithium (12V LiFePO4) battery may consider some parts of the lead-acid charging curve as too high a voltage, and put the battery into standby, so a complete charge won’t be delivered.

The Lithium XS from CTEK is a highly efficient 5A battery charger, specially designed to recharge and maintain the cells of Lithium (12V LiFePO4) batteries. Developed using CTEK’s advanced and patented charging platform, the Lithium XS charger will ensure that Lithium (12V LiFePO4) batteries are charged to maximum capacity to deliver peak power performance every time the vehicle is started, and extend the life of these high performance, high cost batteries.

The Lithium XS features an under-voltage protection system, using a reset function, that will reset the battery management system and bring it out of standby if the voltage has dropped too low. The charger will also check that the battery is accepting charge after deep discharge, allowing the battery to be safely recovered and recharged.

It’s the perfect solution for the charging and maintenance of lithium (12V LiFePO4) batteries.


#1 Maximizes Battery Life

CTEK Smarter Chargers brought to India by naredi maximize the life of your battery. Our patented desulphation function can extend the life of your current battery 2-3 times that of its normal life. With an annual growth rate of over 50% for the last six years, people around the world are finding CTEK chargers as a valuable investment to keep their vehicles, boats, motorcycles, and much more, in prime condition.

#2 High-Quality Engineering

CTEK Smarter Chargers are of the highest quality engineering but don’t take our word for it. CTEK is the preferred battery charger for some of the most prestigious engineering brands in the world: Porsche, Audi, Lamborghini, Bentley Motors, Scania AB, BMW, Rolls-Royce Motor Cars, Chevrolet (Corvette), Ferrari, Alfa Romeo S.p.A., Maybach-Motorenbau GmbH, Aston Martin, Arctic Cat, Yamaha Motor Company, Maserati, Mercedes, and more. Plus, they are available at an affordable cost.

#3 Monitors and Maintains Battery Performance

CTEK Smarter Chargers smartly maintain the battery in prime condition through a series of 4 to 8 steps in our unique charging process. Our chargers constantly monitor the battery to understand the battery condition and then act accordingly: desulphate, revive, charge, condition, and maintain. CTEK Smarter Chargers also regulate the main voltage to protect sensitive and expensive electronic and audio equipment. They even have a backup power supply that allows you to charge vehicle batteries without losing your vehicle’s program settings.

#4 Saves Time, Money and the Environment

CTEK Smarter Chargers can help you save time, battery costs, towing costs, repair costs, and the environment through regular battery maintenance. Why? Battery failure is often reported as the number one cause for breakdowns around the world and with modern vehicles’ complex and sensitive electronic equipment, this continues to be a big issue. As a result, motorists are unnecessarily paying for battery replacements, towing, and mechanic time, then throwing their existing batteries away! (and doing so regularly)

#5 Re-Conditions Old / Dead Batteries

CTEK Smarter Chargers recondition and help revive dead batteries. Our unique reconditioning step allows the battery to recover quickly and last longer.

#6 Affordable Investment

For the cost of a battery, a CTEK charger can keep all of your batteries in prime condition and offer you peace of mind for years to come.

#7 Sparkproof and Shockproof to prevent accidents

CTEK Smarter Chargers are safer to charge with because their spark-free, short-circuit-proof design incorporates a feature that prevents reverse polarity. In other words, the charger will know if you attach one end to the wrong battery post and will not operate if it is attached incorrectly. Conveniently, the red alarm light on the charger alerts you if it wasn’t attached correctly so that you can get it connected properly.

#8 Reliable and nearly indestructible

CTEK Smarter Chargers are durable and can perform under extreme weather environments, with a temperature range of (-4°F to +122°F). They are shockproof, weatherproof, dustproof, and fully approved for outdoor use (IP44-IP65).

#9 Set and Forget

Even though CTEK Smarter Chargers are sophisticated “under the hood”, they are easy to use. CTEK’s patented float/pulse charging allows ‘set and forget’ for months at a time without harming the battery. Motorists do not need to have specific knowledge of batteries or their charging methods. With each Smarter Charger intended for unsupervised use, CTEK is easy and safe to connect. There is no need to even disconnect the battery during use – it’s simply ‘plug and play’.

#10 Multi-Purpose

CTEK’s line of Smarter Chargers suits all types of lead-acid batteries for vehicles of all sizes and types including cars, motorbikes, marine vessels, agricultural vehicles, motor homes, lawnmowers, and more.
