MOVEON GPS Navigation for Hiking - Eastern Japan Edition with 3 Spare Batteries

MOVEON Yamana-bi NGV-M2.5 East Japan Edition
Includes 3 spare batteries. Including the one attached to the main unit, a total of 4 batteries are included. The 3 spare batteries have been charged less than 10 times.
Instruction manual (I don't recall, but the final page for the retailer has been cut off, however, the warranty period has expired)
Genuine charging cable and AC adapter.
Operation is very simple. I also own a Garmin, but this is far easier to use.
Unlike Garmin, the instruction manual can be understood after reading it once.
It takes longer to acquire a GPS signal than with the latest navigation devices.
If you don't need advanced navigation, I think this is good for the peace of mind of being able to route (track) back if you get lost.
In preparation for the discontinuation of sales of dedicated batteries, I purchased new batteries. How about using these as spares for those who are currently using the equipment?
There are no noticeable scratches or dirt.
The price is almost the cost of the batteries, so it's a great deal.
