@GameChanger What you're looking for is "excessive battery drain" when stored. What that is, however, I cannot quantify for you right now. I think there are numerous posts talking about that, though.
The manual says to store a Teric with a full charge and then top it up every 6 months. But then in the specs it says battery life is 50 hours in Dive mode and 3 months in Standby.
So, I'm not sure. But, if I stored mine for 1 month and checked it and it was less than 50% charge remaining, I would start to suspect it may have a problem.
In other news, I am actually wondering now, if my 2nd Teric also has an issue. I did 2 dives yesterday (using 1 AI transmitter). Total dive time was just under 2.5 hours. I started at 100% charge and ended with 86%. If I've done the math correctly, that forecasts 18 hours of total dive time on a charge. The manual says it should get 50 hours of dive time. Now, mine was on Brightness of High, and using AI. But, 18 hours still seems very, very short.
After I get the dives downloaded from it, I'm going to charge it up and store it for a week or 2....
