Expensive for what it is, jury still out. Works great though.
by Adam from Sherman, TX 

Pros: nice way to eliminate a cable, more options for placement of the device when you don't have to worry about a cable
Cons: charging takes forever, not sure it lasts long enough (jury still out).
Review: Well, it is certainly nice to have and it does eliminate one more dangling cable. I've only had the chance to use it once, and the charge only lasted perhaps 2.5 hours. It would be nice if there were some sort of alert it could send to Garmin Pilot that the battery is getting low so you can plug it in. It takes a long time to charge, so I am not sure I let it go long enough the first time so I will give it the benefit of the doubt and charge it longer next time. Still, there aren't really any other options unless you want to hardwire the GDL39 in, so there you are.

Needs fixing
by Paul from Southern Pines NC USA 

Pros: none
Cons: When it gets to 20% battery it flashes on your screen every few minutes,
Review: I purchased the product knowing the battery was limited, but thought that it could go 4.5 hours out of the box. With todays technology we cannot do any better? When battery gets to about 20% it puts a warning box up telling you that the battery is low, but every 1 to 2% change it keeps flashing up. This is happening right as you are getting close to your destination.

Simple and Safe
by William from Mansfield OH USA 

Pros: Comes with wall charger. can be charged while attatched to the GDL 39 3D. Lasts 4 hours.
Cons: None
Review: It's nice to be cordless when my flight is under 4 hrs (the life of the battery) and it's even nicer to know that if I loose onboard power that the battery will allow me to continue receiving weather, traffic, pilot reports, and WAAS level position data for my Garmin Aera 796 which also contains a battery backup.

Almost necessary to use GDL 39
by Kamala from Fort Wayne IN USA 

Pros: GDL39 use is much simpler with the battery
Cons: Way too expensive - Hey! if you can afford to fly, give some to Garmin!
Review: I have used the battery for about a month. Works fine with 120VAC or USB port (with different cables, of course). The battery mounts in the base that comes with the GDL 39 antenna (which is now mounts on the battery). The GDL39 base is so clumsy that I don't use it and mount the battery/antenna on my cowl with velcro - but the bottom of the battery is rubberized so the velcro does not stick very well. OHHH! WElllLLL!

When you are learning, at home, how to use the GDL 39 antenna and the Garmin Pilot software, it is cumbersome without this battery. The GDL 39 works on 12/24VDC and requires WiFi for data and firmware updates. When you go to use 12V car battery, the WiFi signal is not great unless you have a smart phone with WiFi hotspot.

With this battery, life became much simpler during the initial learning period and now when I download charts, live weather etc at my desk prior to a flight.
