Trijicon claims a four-year battery life under continuous use at brightness setting number four for the Adjustable LED RMR. When left on at the brightest setting (brightness setting number eight), the battery is said to last around 25 days. The RMR is just 1-inch tall, but it has a generous 1Ã1 1/16-inch sight window that aids rapid, both-eyes-open, target acquisition and an unobstructed panoramic view for maximum situational awareness. Its eye relief is effectively unlimited. The RMRâs non-magnifying lens receives a 28-layer coating that Trijicon calls True-Color.
A battery reading of 12.4 volts or less should be charged to prevent sulfation. The battery should only be tested after resting for 12 hours. Resting means it has not been charged, or had a load placed on it over a 12-hour time period. The sad news is most RV batteries only last two to three years.
