Garmin GPSMAP 64 SCJ - With Defects

Purchased 6-7 years ago and used for 2-3 years. There are minor scratches from use, but no critical damage, and I believe the screen and the unit itself are in reasonably good condition. Nowadays, smartphones can perform these functions, so it has been left unused for the past 3-4 years. When I turned it on for the first time in a while for listing, it wouldn't power on. Next, when I connected it with a USB cable, it turned on. After leaving it to charge for a while and then removing the cable, it wouldn't turn on, so I thought, What if... and replaced the batteries with AA batteries, and it turned on. Reason for as-is condition 1: The genuine battery is completely degraded and unusable. Reason for as-is condition 2, and this is important: You can see two thin horizontal lines in the approximate center of the screen. I'm not sure if they will disappear or worsen in the future, perhaps due to turning it on after a long time. It was never used for mountain climbing. Depending on the individual, this might be a concern. I was a little concerned about it myself. A microSD card labeled Japanese Topographic Map TOPO10M Plus V4 is inserted inside the unit. I will leave the new AA batteries in. The degraded battery will be included for reference. There are two types of mounting adapters for the main unit: a carabiner type and a Velcro type for attaching to the chest of a backpack, etc. Please check the images for other accessories.
