Similar problem with my Garmin GPS 72, that was kept on the boat in a dry locker as a backup. I brought it home and put new batteries in and it did not start. However, I have the 12v + data cables for it so tried it using the car socket. It started no problem and took about 10 minutes to get a position. Date and time were correct as well despite GPS roll over. I bought it in 2005 so 19 years old.
10 mins is not bad - considering it probably was updating its almanac.
