FOXSUR 12V 24V Waterproof Truck Car Battery Charger, EFB GEL WET AGM Battery Charger with LCD Display, Battery Type Selectable
Charger for Battery Size:
12V for 24AH - 200AH
24V for 12AH - 100AH
• Microprocessor Control (CPU).
• 11-STAGE AUTOMATIC CHARGING:
• This is a fully automatic battery charger with 11 charge stages.
• Automatic charging protects your battery from being overcharged. So you can leave the charger connected to the battery indefinitely.
• 11-stage charging is a very comprehensive and accurate charging process that gives your battery longer life and better performance compared to using traditional chargers.
• 11-stage chargers are suitable for most battery types including Calcium, EFB, Gel and AGM, Wet batteries. They may also help restore drained and sulphated batteries.
• Switchmode technology: Yes
• Polarity protection: Yes
• Output short protection: Yes
• Non battery link protection: Yes
• Over voltage protection: Yes
• Over temperature protection: Yes
• Cooling : Natural convection
• Input voltage: 180-260V AC, 50-60Hz
• Rated output: 12V DC 8A, 24V DC 4A
• Minimum start voltage: 2.0V
• The 11 stages are: Diagnosis, Boosting, Pre-Charge, Soft Start, CC1, CC2, CC3, CV, Testing, Desulphation, Restart.
• Thermal protect : 65'C+/-5'C
• Efficiency: App. 85%.
• Compliant standards: CB,CE, IEC60335, EN61000, EN55014
1. Diagnosis: Check the battery status.
2. Boosting: Check the battery can save power.
3. Pre-charge: Use small current to charging.
4. Soft start: The battery voltage will increase slowly.
5. Constant current 1: Use Max. Current to charging.
6. Constant current 2: Use 3/4 Current to charging.
7. Constant current 3: Use 1/2 Current to charging.
8. Constant voltage :
The battery can charge up to almost 90%.
The charging current tapers and the charging voltage are kept constant at the set value.
9. Testing(2 minutes):
The charging is interrupted for a short period while battery voltage is measured.
If the battery voltage falls too quickly, the battery could be faulty.
(if battery discharge quickly(don't can hold voltage), the charger will go to Desulphation-mode , otherwise LCD display: FUL)
10. Desulphation(2 Hrs):
Charger will go into this stage if battery fails, Testing Mode due to its condition, age or being under charged.
This stage can recover batteries from deeply discharged state increasing performance and battery life.
11. Restart mode
This mode allows the charger to effectively be left connected to your batteries; it works at a safe level and ready for use.
The program engages a special charging waveform and monitors the battery voltage variety, if the battery voltage sinks, the special pulses will keep the battery in optimal state, if the battery voltage drops even lower, the battery charger will switch into bulk charging . The maintenance mode allows the charger to be connected to the battery over the course of a season;
