Default TCW backup battery buzzing
Noticed today when I turn on main power switch I have a buzz from the TCW backup battery. Has anyone noticed this? I don't recall any buzz when I wired it in initially. Could this be normal??

Nope, never heard any buzzing. Come to think of it, my TCW backup battery has worked flawlessly since first flight in 2014. Have never touched it or plugged the charger into it.

Wondering what the outcome was as mine is also buzzing.
