Hot selling! Factory best price good quality lead acid Battery chargers for lead acid battery 12V 20A Charger

Technical Parameters

• Microprocessor Control (CPU).

• 7-STAGE AUTOMATIC CHARGING:

• This is a fully automatic battery charger with 7 charge stages.

• Automatic charging protects your battery from being overcharged. So you can leave the charger connected to the battery indefinitely.

• 7-stage charging is a very comprehensive and accurate charging process that gives your battery longer life and better performance compared to using traditional chargers.

• 7-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

Product Overviews

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. Soft Start

A preliminary charge processes that gently introduces power to the battery. This protects the battery and increases battery life.

3. 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 14.4 volts for 12V charger

4. 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 14.4 volts for 12V charger while the current is gradually reduced until no more power can be added without over-charging the battery.

5. Battery Test

An automatic battery test is conducted immediately after the absorption stage. The test monitors the voltage for 90 seconds to determine if the charge was successful.

6. Recondition

The battery reconditioning function is initiated automatically in the case that the battery fails the battery test (stage 5). Failing the battery test indicates that the absorption stage was unable to fully charge the battery. The recondition mode will then begin to introduce a low constant current for a period of 4 hours. Then the charger will go into float charging mode.

7. 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.

• Cooling fan: Automatic temperature controlled.

Reverse connection protection.

Correct connect for the battery, and charger works well.
