I have an Arva Evo 3+ that is about five years old. I can't tell if there is some sort of malfunction regarding how it uses batteries.
To wit: Put fresh regular Energizer batteries in and turn on for the first time: screen says battery life at 95%
Use for six hours, turn off, battery life at 80%
Leave in house for roughly three weeks, turn on, and battery life at 40%. Use for six hours, turn off, battery at 30%
Bascially, nearly half of the battery life is sucked up in three weeks of sitting in a house unused. This has been going on for a while. Batteries are fresh from the store and the inside of the battery case is clean.
I have contacted Arva and their Boise rep but no response.
Is that normal?
