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.
It is believed that priming becomes necessary if the voltage drops below 1V/cell. Primary alkaline and lithium batteries can be stored for up to 10 years with only moderate capacity loss. You can store a sealed lead acid battery for up to 2 years. Since all batteries gradually self-discharge over time, it is important to check the voltage and/or specific gravity, and then apply a charge when the battery falls to 70 percent state-of-charge, which reflects 2.07V/cell open circuit or 12.42V for a 12V pack.
