I removed my mechancal vario a couple years ago and replaced it with a
Borgelt B40 which as a 9Volt battery backup. I have had to use the
battery backup once. I am very pleased with this arrangement. My main
reason for changing was that I wanted an Audio on my backup vario.

I am considering dropping a Winter Vario from my panel . I have a Glide
computer and primary electric vario on board as well, as an Ilec
electric. Just trying to lose some weight from the cockpit.
Any PRO's or CONS's I need to know about regarding reliability and
redundancy in flight......batteries in the cold etc??
