The Trojan 31-AES 12V AGM Battery is a high-capacity, deep-cycle AGM battery engineered for applications that demand maximum runtime, durability, and long service life. Built on Trojan AES advanced AGM technology, the 31-AES delivers up to 3x the cycle life of standard AGM batteries, making it ideal for commercial, industrial, and recreational power systems.

Designed to perform under extreme deep-cycling conditions (up to 100% depth of discharge), the Trojan 31-AES maintains high energy output even in partial state of charge (PSoC) operation and in harsh temperature environments. Its maintenance-free, non-spillable VRLA design allows for safe horizontal mounting, providing installation flexibility in tight or challenging spaces.
