Battery charger EXPERT CHARGER 15 12V 15A EXCHARGE15

Technical Parameters

EXPERT CHARGER 15 is an electronic charger for charging 12-volt batteries:

WET (liquid - acid)

GEL (gel)

MF (maintenance-free)

AGM (with fibreglass mat)

EFB (for vehicles with Start-Stop system)

CAL (calcium)

LFP (lithium iron phosphate)

 

Microprocessor control system ensures an automatic charging process. Once the required voltage is reached on the battery, it switches to maintenance status and automatically resumes charging after a voltage drop on the battery.

EXPERT CHARGER 15 has 4 charging modes :  

• STD – liquid acid batteries WET and MF
• AGM – AGM, gel, EFB batteries
• CAL – calcium batteries
• LiFePO4 – lithium iron phosphate batteries (LFP)

 

Charging Process

9-stage charging process ensures optimal charging conditions for the battery. The automatic control system adjusts each of the 9 charging stages for correct battery charging:

• STAGE 1 - DIAGNOSTIC – analyses the battery and checks if it can accept charging current; prevents charging of a damaged battery.
• STAGE 2 - RECOVERY CHARGE – batteries with low voltage are pre-charged with a small current but increased voltage; very discharged batteries can be restored to usability, ensuring longer battery life, the stage is skipped if the battery is minimally discharged and in good condition.
• STAGE 3 - SOFT START - the charger gradually increases the charging current to reach the set charging current.
• STAGE 4 - PULSE CHARGE – the battery is charged with a pulsed current (pulse fluctuations occur within the DC current range).
• STAGE 5 - RECONDITIONING – preparatory stage for charging in the bulk charge stage.
• STAGE 6 - BULK CHARGE – charging with a constant current value to a previously set voltage (14.4÷14.7V).
• STAGE 7 - ABSORPTION CHARGE – after reaching the required battery charge level, it switches to constant voltage charging (CV) and the charging process ends.
• STAGE 8 - EVALUATION DIAGNOSTIC – automatic monitoring of battery voltage after charging is completed.
• STAGE 9 - MAINTENANCE CHARGE – battery maintenance stage (float) and monitoring its condition; resumes charging with reduced current if necessary.

 

Physical Parameters

The device is equipped with protection: thermal, against sparking on the terminal clamps, against short circuiting of the terminals, overload, and reverse polarity.

Specially designed housing allows the charger to be mounted on the wall which saves valuable space in the garage or workshop.

Charging cables are 2 metres long and are equipped with an ambient temperature sensor. Its function is to adjust the appropriate voltage during charging, in relation to the ambient temperature. Only for STD, AGM, and CAL modes.

 

Power Parameters

Single-phase power supply 230V.

Power cable length 2m.

The device is equipped with a power plug.
