Deltran Battery Tender 4-Bank International 12V Charger

What to Expect

The best way to eliminate battery sulfation is to prevent it. The Deltran Battery Tender will fully charge four batteries and maintain them at the proper storage voltage using a 4-step charging process:

Step One: Initialization
The monitor circuit verifies appropriate battery voltage levels and good electrical continuity between the battery and the charger DC output.

Step Two: Bulk Charge
The charger delivers a constant current at full power until 75-80% of the batteries are fully recharged.

Step Three: Absorption Charge
The charger conditions the batteries for optimum performance, delivering a constant charge at absorption level. The charge ends when the battery charging current drops below the optimum recharge threshold.

Step Four: Float Charge
The charger keeps the batteries fully charged and maintains a high specific gravity. A full charge reset monitor protects the batteries from excessive appliance current draw while charging.

Uses & Compatibility

The Deltran 4-Bank battery tender is for use with 12-volt lead-acid batteries, including Absorbed Glass Matt (AGM), Maintenance-Free (MF) and flooded.

    Have used one for over 12 years and have not had any issues. Never have to worry about any battery go dead.

    I picked up this charger because I have a boat and a jet ski out side. So I ran the 25' cables though the garage wall now I have everything charged and ready to go anytime. The main unit is inside garage on self and also hooked to motorcycle inside. Thanks for this great set up.
