Maxguard® T2 Separator & Alpha Plus® Paste Proprietary technologies ensure consistent performance and extended overall life cycle. Like other Trojan Motive batteries, the T-145 incorporates advanced materials delivering superior durability and cycling capability.

260Ah High Capacity Delivers approximately 15% more capacity than standard T-105 (260Ah vs. 225Ah), providing extended runtime for demanding applications where maximum energy storage is critical.

GC2H Taller Case Design Enhanced case height accommodates additional plate material and electrolyte, maximizing capacity while maintaining standard GC2 footprint for length and width compatibility.

Optimized for Deep Cycling Engineered specifically for frequent, deep discharging applications. Thick plate construction and advanced materials withstand the rigors of daily deep-cycle use in demanding industrial environments.

Maintenance Requirements

The T-145 LPT Mastervent is a flooded lead-acid battery requiring regular watering with distilled water to maintain optimal performance and lifespan. The Mastervent™ system simplifies maintenance while enhancing safety by reducing acid leakage risks and controlling charging gases. Batteries must be shipped and stored upright to prevent acid spills.

System Configuration & Handling

Multi-Battery Systems: The T-145 is a 6V battery rarely used alone. Typically sold and installed in sets to create higher voltage systems:

• 12V systems: Two batteries in series
• 24V systems: Four batteries in series (common for solar)
• 36V systems: Six batteries in series
• 48V systems: Eight batteries in series (golf carts, industrial)

Shipping & Handling: At 72 lbs per battery, the T-145 requires proper lifting equipment and techniques. Complete systems can weigh 288-576 lbs depending on configuration. Upright positioning required during shipping and storage to prevent acid leakage.

Why Choose the T-145 LPT Mastervent?

When maximum capacity in a 6V platform is essential, the T-145 LPT Mastervent delivers uncompromising performance. The 260Ah capacity provides approximately 15% more runtime than standard T-105 batteries, making it ideal for operations where extended energy storage justifies the additional investment. Low Profile Terminals ensure installation flexibility in height-restricted compartments, while Mastervent™ technology enhances safety and simplifies maintenance. For solar installations, heavy-duty industrial equipment, and maximum-range applications, the T-145 represents the premium choice in 6V deep-cycle flooded technology.

T-145 vs. T-105 Comparison

The T-145 offers 260Ah capacity compared to the T-105's 225Ah, providing approximately 15% more runtime for demanding applications. The T-145 features a taller case (GC2H vs. GC2) and weighs more (72 lbs vs. 62 lbs), accommodating the additional capacity through increased plate material and electrolyte. Both batteries share the same footprint length and width, ensuring compatibility with standard battery compartments that have adequate height clearance. The T-145 is ideal for maximum runtime and heavy-duty applications, while the T-105 suits standard deep-cycle requirements. Both require regular watering maintenance and feature Trojan's proven T2 Technology.

Critical Installation & Maintenance Notes

Battery Watering Instructions: As a flooded battery, the T-145 requires regular watering with distilled water. Consult the battery watering instructions provided with your shipment or contact technical support for proper maintenance procedures. Neglecting watering will significantly reduce battery lifespan and performance.

Upright Positioning Required: Must be shipped, stored, and installed in upright position at all times to prevent acid spillage. Never tilt or invert flooded batteries.

Proper Charging Equipment: Ensure charging equipment is configured for flooded lead-acid batteries. Using incorrect charger settings will damage batteries and void warranty.

Ensure optimal performance with proper charging profiles for flooded batteries and regular maintenance schedule. Professional installation recommended. Contact us for battery watering instructions and application-specific technical support
