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.
Under ideal conditions, one automobile battery can last up to six years, but several factors decrease this optimal lifetime. A study of 2,769 sample 12 volt batteries conducted in 2004 showed that the average lead acid battery life is 50 months. Batteries in the northern US had an average life of 56 months compared to those in the south which had an average life of 43 months. Lead acid batteries last longer in cold climates as warm climates increase water loss and sulfation. Car battery life span range is 2 to 5 years.
