Hi, A few year ago I bought a Dual XGPS 170 so I could get on the ADS-B IN bandwagon. It worked very well for quite a while but lately it hasn’t taken a charge. In fact then I plug it in to a charger the red charge light will only stay on for a few minutes before it blinks off.
I tried various chargers always with the same result. I checked the users manual on the Dual webpage and it advised me as to which charger to use. I tried that but nothing worked.
Finally I called Dual tech services only to be told that the battery only lasts about three years and I would need to either send it in to Dual for the battery change or I could change it myself.
I contacted sales and service and was told that the cost of the battery was $40 but before they would send it I would have to send them an email stating that I would accept full responsibiltiy for any problems created by installing the battery. I felt I was competent to install the battery so I so stated.
Anyway, the battey is on it’s way and I’ll be using my EFB again soon.
