2. Safety Information

Always prioritize safety when handling batteries. Adhere to the following guidelines:

• Ventilation: Ensure adequate ventilation in the area where batteries are being charged or stored. Although AGM batteries are sealed and designed for 99% recombination capabilities with no dangerous fumes or gases under normal operation, proper airflow is always recommended.
• No Sparks or Flames: Keep batteries away from open flames, sparks, and other ignition sources.
• Eye Protection: Always wear appropriate eye protection (safety glasses or goggles) when working with batteries.
• Gloves: Wear insulated gloves to prevent accidental short circuits or contact with battery terminals.
• Proper Lifting: These batteries are heavy (approximately 370 pounds for the set of four, or about 92.5 pounds each). Use proper lifting techniques or assistance to avoid injury.
• Tool Safety: Use insulated tools to prevent accidental short circuits across battery terminals. Remove all metallic jewelry before working with batteries.
• Disposal: Dispose of old batteries responsibly according to local regulations. Do not incinerate.

3. Product Features

The VMAXTANKS XTR12-155 batteries incorporate advanced features for reliable power delivery:

• AGM Deep Cycle Technology: Utilizes Absorbent Glass Mat technology for superior deep cycling capabilities, allowing for repeated deep discharges and recharges without significant loss of capacity.
• Heavy Duty Xtreme Series: Designed for demanding applications, offering faster charge delivery and enhanced deep cycle performance.
• Maintenance-Free Operation: Sealed construction eliminates the need for watering or electrolyte checks, providing a hassle-free experience.
• Gas Recombination: Engineered for 99% gas recombination, preventing the release of dangerous fumes or gases under normal operating conditions.
• Low Self-Discharge: Exhibits minimum self-discharge in standby and backup modes, ensuring power retention over longer periods of inactivity.

4. Setup and Installation

Proper installation is crucial for optimal performance and longevity of your VMAXTANKS batteries.

1. Inspection: Before installation, inspect each battery for any signs of damage. Verify that the dimensions (12.9"L x 6.9"W x 10"H, 10.8"H including terminals) are suitable for your battery compartment.
2. Preparation: Ensure the battery compartment is clean, dry, and free of debris.
3. Orientation: Install batteries in an upright position. While AGM batteries are spill-proof, upright installation is recommended for optimal performance and lifespan.
4. Connections:
   • Connect batteries in series or parallel as required by your golf cart or application's voltage and capacity needs. For golf carts, batteries are typically connected in series to achieve higher voltages (e.g., 36V or 48V).
   • Ensure all connections are clean and tight. Loose connections can lead to resistance, heat buildup, and reduced performance.
   • Connect the positive (+) terminal of one battery to the negative (-) terminal of the next battery for series connections.
   • Always connect the main positive cable last and the main negative cable first when disconnecting.
5. Charging System: Ensure your charging system is compatible with AGM batteries. An AGM-compatible charger is essential for proper charging and to prevent damage to the batteries.

5. Operating Instructions

To maximize the performance and lifespan of your VMAXTANKS XTR12-155 batteries, follow these operating guidelines:

• Initial Charge: It is recommended to fully charge the batteries before their first use.
• Charging Voltages:
  • Bulk Charging Voltage: 14.5V - 14.9V per 12V battery. This is the primary charging stage where the battery receives the majority of its charge.
  • Float Charging Voltage: 13.5V - 13.8V per 12V battery. This is a maintenance charge to keep the battery at full capacity when not in use.
• Avoid Deep Discharges: While these are deep cycle batteries, consistently discharging them below 50% capacity can reduce their overall lifespan. Recharge as soon as possible after use.
• Regular Recharging: For optimal performance, recharge batteries after each significant use, even if not fully discharged.
• Storage: If storing the batteries for an extended period, ensure they are fully charged and stored in a cool, dry place. Periodically check the voltage and top-off the charge if necessary to prevent sulfation.

6. Maintenance

VMAXTANKS AGM batteries are designed to be maintenance-free, but a few simple checks can ensure their longevity:

• Terminal Inspection: Periodically check battery terminals for corrosion or loose connections. Clean terminals with a wire brush if corrosion is present and ensure all connections are tight.
• Battery Exterior: Keep the battery exterior clean and dry. Wipe off any dust or dirt with a damp cloth.
• Charging System Check: Ensure your charger is functioning correctly and providing the specified charging voltages.
• Environmental Conditions: While robust, extreme temperatures can affect battery performance. Operate and store batteries within recommended temperature ranges.
