Used Garmin Rino 530. This is not an HCx model. . Powers on and acquired satellite signal. Original battery is untested. I don’t have any way to charge the original unit. I bought an after market charger but do not have the clip to plug the adapter into. Purchased a brand new Garmin Alkaline battery pack and the unit runs just fine off of that. I’m including the ac adapter, extra battery pack and the original untested battery. You will need to purchase an additional clip in order to try to test the new battery. The date on the screen shows as 2004 when it is turned on. Cat10 b13
