Land Rover Battery Chargers

CTEK battery chargers are perfectly suited for charging all types of lead-acid batteries. A CTEK charger is easy to use. It can be connected for an extended period gently maintained by pulses. The charger is electronic safe, which means you do not normally need to remove the battery from the vehicle when charging. In addition it is reverse polarity protected and short circuit proof. The charger also has spark protection system. CTEK battery chargers are approved for outdoor use.

The following models are available in the CTEK charger range – all with pulse maintenance:

Charging Equipment

Modern electronics technology put advanced battery chargers within reach of the man on the street.

CTEK, an acclaimed Swedish manufacturer, has recently launched its range of popular battery chargers in South Africa. CTEK chargers are state-of-the-art, compact and affordable and boasts

• An intelligent (controlled) charging program which ensures that the battery is charged to full capacity whilst preventing over-charging or under-charging. 

• Capability to be coupled permanently or for long periods to a battery without drying out the battery. The farmer, caravan, aircraft and  boat owner can now ensure that batteries are always serviceable even if equipment is not used for extended periods..

CTEK chargers are safe to use:

• Will not damage sensitive vehicle electronics.

• Do not cause sparking on connection to battery.

• Are short circuit proof and reverse polarity protected.

• Ensure minimal release of explosive gas from battery during charging.

CTEK chargers are simple to use:

• Automatic pulse maintenance for maximum battery life.

• Ideal charging even with varying mains supply.

• Brings drained batteries back to life.

CTEK chargers are flexible to use:

• Suitable for all lead acid battery types: Open, Maintenance Free, Gel and AGM

• Able to wake up a mildly sulphated battery that “won’t take charge”.

• Moisture proof and dust proof - safe for outdoor use

The CTEK charger program

CTEK chargers have automatic charging programs consisting of up to eight steps, depending on the model.

Smaller CTEK chargers up to and including the Multi XS 3600 model (12 Volt, 3,6 Ampere, especially suited for general household use) have the following program steps:

Heavy duty professional chargers up to the Multi XS 25000 model (12 Volt, 25 Ampere) are suited for more demanding applications and have the following program steps (*)

Getting the best service from your vehicle battery.

Correct application and maintenance is the key to long and trouble free service from modern vehicle batteries. Apply the following simple guidelines and your battery will not let you down:

• Batteries must always be kept correctly charged

• Correctly maintain battery electrolyte levels

• Keep batteries clean

How does my battery work and why do I need a good charger?

Vehicle batteries consist of a number of secondary or rechargeable cells.

When power is supplied, electrical current flows between the electrodes and reactions take place which changes the chemical composition of the plates and dilutes the electrolite. When the electrolyte gets depleted, the battery voltage drops quickly and the internal resistance of the battery increases. The battery is now not capable of delivering the high current required to start an engine. Such a battery may still be able to operate vehicle lights but is not able to crank the engine.

Passing electrical current through them in the opposite direction of supplying power can charge secondary cells. During this process the reverse chemical reactions to discharging take place and the battery is converted to the charged state. When the battery is fully charged a process of decomposition of water in the electrolyte into hydrogen (dangerous explosive gas) and oxygen begins. This is referred to as “gassing”, releasing gas from the battery whilst depleting water in the electrolyte.

Sulphation

Lead-acid batteries are prone to a degenerative process known as sulphation. The microscopically small lead sulphate crystals which forms during discharge on both electrodes with time tend to grow together into large crystals when discharged batteries are left standing without recharging. When the lead sulphate crystals become so big that they cannot be broken down during the charging process it results in a permanent loss of capacity “the battery will not take charge”. Sulphation can even lead to the deformation and damaging of the plates.
