I purchased a well used DJ-G7 and found the batteries depleted quickly; so I purchased a new battery and desk top charger. And I made up a power cord to operate as needed from my LiPo. But battery life seemed too short so I use this HT only for 23cm and rely on my Th-D74A for GPS, APRS, and 144, 222, and 446. When I carry the DJ-G7 to a summit I carry 2 batteries for back up. A friend uses the DJ-G7 for all three bands and has no battery life issues. I have thought that operator error might be an issue or just bad luck! Even so, I’m still looking for a DJ-G29 to add 33cm to my capability! I wonder if there is a non-OEM battery available?
