    Hi,


    Had my ET-8000 for about 5 years. I've read dire warnings not to remove the battery, but does it have a finite lifespan?


    Is there any way to monitor the battery status?


    Thanks

    i am not sure about latest models (8000 and 10000) for the other models there is a driver release, which allows the receiver to live without the security chip control.


    before that, i was using (and the receiver still works in a friends hands) an et9000 from 2011, so the battery has a long life

    Thanks. I may whip the top off and check the voltage. I've seem procedures where they solder in a 3v battery to maintain the voltage while the on board battery is changed. May have a go (as going out activities and being seriously curtailed.)
