5.10.2 Rain Logger Battery

The Rain Logger is powered by a standard 9V alkaline battery and should be replaced periodically. The Levelogger Software provides a reading of the approximate battery life remaining when connected to a Rain Logger. It is recommended that the battery be changed when remaining life falls below 40%.

The 9V battery is located inside the logger housing. To access the battery, loosen the 4 screws on the corners of the case with a standard screwdriver. The battery can be disconnected at any time but tipping events may be missed if battery change occurs during active rainfall or when a reading is being logged. If the Rain Logger is logging, the lamp on the front face of the Rain Logger will flash every minute. Wait until the lamp flashes and then exchange the old battery with a new one within 1 minute.

There is a clock battery inside the unit which is mounted to the printed circuit board. This battery powers the logger's internal clock and should last the lifetime of the logger.
