Battery charger EXPERT CHARGER 25 12/24V 4/12/25A EXCHARGE25V2

• STD – acid liquid batteries WET and MF (additional winter mode)
• AGM – batteries AGM, EFB (additional winter mode)
• GEL – gel batteries
• LiFePO4 – lithium iron phosphate batteries (LFP)

The device is additionally adapted for charging motorboat batteries 

(type MARINE).

The charger also has additional functions, such as:

• BOOST - function allowing quick battery charging with increased current (e.g. for starting)
• POWER SUPPLY - function for maintaining constant voltage (e.g. when replacing the battery in the vehicle)
• ALTERNATOR - function allowing simple alternator verification test

Charging Process

7-stage charging process ensures optimal battery charging conditions. The automatic control system adjusts each of the 7 charging stages for correct battery charging:

• STAGE 1 - Diagnostic (Diagnostics) – analyses the battery and checks if it can accept charging current; prevents charging of a damaged battery
• STAGE 2 - Recovery charge (Pre-charge) – batteries with low voltage are pre-charged with a small current but increased voltage; very discharged batteries can be restored to usability and this ensures longer battery life, the stage is skipped if the battery is minimally discharged and in good condition.
• STAGE 3 - Soft start (Soft start) – the charger gradually increases the charging current to reach the set charging current
• STAGE 4 - Bulk charge – charging with a constant current value to a previously set voltage (14.4÷14.7V)
• STAGE 5 - Absorption charge – after reaching the required battery charge level, it switches to constant voltage charging (CV) and the charging process ends
• STAGE 6 - Evaluation diagnostic - automatic monitoring of battery voltage after charging is completed
• STAGE 7 - Maintenance charge – maintenance stage (float) and monitoring of its condition; resumes charging with reduced current if necessary.
