PRODUCT FEATURES

• This appliance has been designed for charging a variety of SLA batteries (sealed lead acid batteries), as mainly used in cars, motorbikes, and several other vehicles. They may be of types e.g. WET (with liquid electrolyte), GEL (with mit gel-type electrolyte), or AGM (absorbed glass mat) batteries. A special design of the appliance (also named, ten-phase-charging strategy”) enables the recharging of the battery to almost 100 % of its original capacity. Connecting the battery for a long period to the battery charger is also a good way of ensuring that your battery is kept in optimum condition. The”ten-phase-charging strategy” is as follows:

Step 1: Check

• Checks the battery voltage to make sure battery connections are good and the battery is in a stable condition before beginning the charge process.

Step 2: Recovery

• Initializes the Recovery process, if needed, for deeply discharged or sulfated (desulfation) batteries by pulsing small amounts of current.

Step 3: Soft Start

• Slow charge and protect for deeply discharged or sulfated (desulfation) batteries by multi -phase of current.

Step 4-7: Bulk

• The Bulk charging process continues using both a High Rate and Medium Rate charge and returns 80% of battery capacity, Indicated by the 20%, 40%, 60%, 80% and 100% LCD.

Step 8: Absorption

• Brings the charge level to 80%, The battery charger will deliver small amounts of current to provide a safe, efficient charge and limit battery gassing.

Step 9: Analyse

• Tests if the battery can hold charge. Batteries that cannot hold charge may need to be replaced.

Step 10: Maintenance

• Continuously monitors the battery voltage to determine if a maintenance charge should be initiated. If the terminal voltage falls below 12.BV (12V) and 25.6V (24V), the charger will start the Maintenance cycle until voltage reaches 13.6V (12V) and 27.2V (24V) and then discontinues the charge cycle. The cycle between Trickle and Maintenance is repeated indefinitely to keep the battery at full charge, without overcharging. The battery charger can be left connected indefinitely.

OPERATION

WARNING!

• Before you carry out any work on the battery charger always pull the mains plug out of the mains socket.

WARNING!

• DANGER OF ELECTRIC SHOCK! DANGER OF DAMAGE TO PROPERTY! DANGER OF INJURY!
