The Trojan 27TMX is a 12V flooded/wet lead-acid deep cycle battery designed for applications requiring dependable repeated discharge and recharge performance. The battery is rated at 105Ah at the 20-hour rate and uses Trojan's T2 Technology deep-cycle design.
This configuration uses the WNT Wingnut Terminal and a durable polypropylene case and cover. With multiple capacity ratings across different discharge periods, substantial reserve performance, and manufacturer-defined charging parameters, the 27TMX is designed for properly maintained deep-cycle battery systems.
T2 Technology
Trojan identifies the 27TMX as a 12V deep cycle battery incorporating its T2 Technology, developed for demanding deep-cycle applications requiring repeated discharge and recharge operation.
Flooded Deep Cycle Construction
Uses traditional flooded/wet lead-acid battery technology designed specifically for deep-cycle operation.
105Ah Deep Cycle Capacity
Provides a 105Ah capacity rating at the 20-hour discharge rate, with additional manufacturer ratings available at multiple discharge periods.
Wingnut Terminal Configuration
This configuration uses Trojan's WNT wingnut terminal for secure cable attachment in compatible battery installations.
High Reserve Capacity
Trojan specifies substantial runtime under standardized constant-current discharge testing, providing useful reserve energy for deep-cycle applications.
Polypropylene Construction
The battery uses a polypropylene case and cover with Trojan's distinctive maroon finish.
Temperature-Compensated Charging
Trojan provides temperature-compensation guidance for charging-voltage adjustment when battery temperature differs from the manufacturer's reference temperature.
Off-Grid Battery Systems
Suitable for compatible battery-based systems requiring a serviceable flooded deep-cycle battery for repeated energy storage and discharge.
Renewable Energy Storage
Can be used in properly designed renewable-energy battery banks when charging equipment is configured for the battery's flooded lead-acid charging requirements.
RV & Mobile Power Systems
Suitable for compatible mobile electrical systems where a flooded deep-cycle battery can be safely installed in an appropriately ventilated battery compartment.
Marine Battery Systems
Suitable for properly designed marine auxiliary power applications where installation, ventilation, charging, and maintenance requirements for flooded batteries are met.
Deep-Cycle Equipment
Designed for applications requiring repeated discharge and recharge cycles rather than primarily engine-starting service.
Battery Bank Applications
Can be incorporated into properly engineered battery-bank configurations where system voltage, capacity, charging, cabling, and overcurrent protection are appropriately designed.
