Car Battery Charger Smart Repair 12V5A 4-Stage Waterproof Battery Charger
Professional car battery battery charging airport factory manufacturing
• Microprocessor Control (CPU).
• 4-STAGE AUTOMATIC CHARGING:
• This is a fully automatic battery charger with 4 charge stages.
• Automatic charging protects your battery from being overcharged. So you can leave the charger connected to the battery indefinitely.
• 4-stage charging is a very comprehensive and accurate charging process that gives your battery longer life and better performance compared to using traditional chargers.
• 4-stage chargers are suitable for most battery types including Calcium, Gel and AGM, Wet batteries. They may also help restore drained and sulphated batteries.
• Types of batteries: Most types of lead acid batteries including Calcium, GEL and AGM, Wet , SLA,EFB, etc..

1. Desulphation
The Desulphation stage may break down sulphation that occurs in batteries that have been left flat for extended periods of time, returning them back to full charge. sulphation occurs when lead-sulphate hardens and clogs up the battery cells.
2. Bulk (Constant Current)
Bulk mode charges the battery at the maximum rate (constant current) putting a large amount of power into the battery in a short amount of time. This stage will charge the battery to approximately 80%, until the voltage reaches 14.5 volts for 12V charger
3. Absorption (Constant Voltage)
The charge rate slows down so the battery can absorb more power and reach 100% charge. The voltage remains at a constant 14.5 volts for 12V charger while the current is gradually reduced until no more power can be added without over-charging the battery.
4. Float
The Float stage maintains the battery at 100% charge without overcharging or damaging the battery. This means the charger can be left connected to the battery indefinitely.
