Need a deep-cycle RV battery? The Trojan T-105 Plus Lead-Acid Deep-Cycle RV Battery is an excellent choice. The Trojan L-16 and T-105 batteries have a long and great history supplying dependable power, and the updated T-105 Plus continues that reputation and adds flip-top vent caps, water level indicators inside each cell, and embedded terminal posts.

Trojan deep-cycle batteries are almost legendary for their reliability and longevity, especially in the renewable energy world. Their key features include:

  • American-made - Founded in 1925 in Los Angeles, California, Trojan is now a global leader (sold in over 125 countries) in deep-cycle batteries with four ISO 9001-certified manufacturing plants: Santa Fe Springs (California), Lithonia and Sandersville (both in Georgia), and one in Sligo, Ireland.
  • Precision manufacturing - Trojan has invested heavily in highly-automated manufacturing processes, commissioning custom-designed Cast-On Strap (COS) machines. Invented for auto manufacturing, COS machines enable precise alignment of components, eliminating the potential for human error during manufacturing and producing very consistent quality.
  • Thorough testing - Trojan products undergo extensive automated quality testing during manufacturing, including high-voltage short-circuit tests, weld shear tests, and pressure-testing for leaks. Trojan lead-acid deep-cycle batteries are tested and certified against the IEC 61427 standard for photovoltaic systems, proving their real-world toughness against high temperatures (of 104 degrees Fahrenheit, or 40 degrees Celsius) and deep discharges even when the battery is not fully-charged.
  • True deep-cycle design - Lead-acid batteries are the most widespread choice for dependable power delivered at the lowest cost. The lead-antimony alloy used in the T-105 Plus improves its deep-cycling capabilities and reduces hydrogen generated during charging, and its thick plates allow it to withstand repeated deep-cycling. 

Lead-acid batteries do require maintenance for the longest life, especially regular watering with distilled water. Trojan's HydroLink battery watering system helps make this maintenance much easier.
