I have been using Energizer Lithium E2 AAA cells to power microwatt telemetry transmitters for a couple of years. These were my choice not only for their long life, but also because they are suppose to be able to sustain their voltage in extreme hot and cold temps.
I have run into an issue on several occasions where my transmitters stop working, and when recovered, the battery is not dead , but instead has a voltage far above 1.5 volts, sometimes double that. What could be causing this? I could understand if they went dead because of current draw or whatever, but this isn't the case.
This problem has mortally damaged several of my transmitters.
I use 5 minute epoxy to attach the battery/transmitter combo, and have wondered if I have been covering up the battery's vent holes or something like this.
Can anyone supply me with any ideas on this problem, or suggest an alternative way around this?
Thanks Jim
