G5 battery drain SB 22013

[chemgeek]

So Garmin has finally officially owned up to the problem of G5s irreversibly draining the backup batteries during periods of inactivity with this service bulletin. I raised this issue with Garmin 2 years ago and was given the brush-off. Looks like three versions of backup batteries and software upgrades did not solve the issue, so now a hardware modification is required. The worst part is that Garmin will pay for the labor to comply only if done at a Garmin dealer, despite the fact that non-dealers can install the equipment. My G5 backup batteries will discharge at a rate of about 10-20% per week. If they ever get to zero, the batteries cannot be recharged. Not sure why they need to draw current while they are shut off.

Consider yourself fortunate Garmin is paying for a fix vs an AD requiring changing every 30 days.
