Uses single 3V lithium cell battery #2032.
Have not done a run test so I don't know how long it lasts.
The LEDs are arranged in a 7x21 array, overall display size is 15mm x 70mm.
On average it looks like the display fits around 4 characters but it depends on if you are using upper or lower cased characters.
You can store up to 6 different messages (only 1 can display at any one time.) First message can be up to 512 chars, the other 5 can be up to 255 chars.
There is a scrolling speed control (1 slowest - 9 fastest) that can be set.
No flashing setting.
Not sure how readable in sunlight. There is a luminance setting (1 dim - 9 bright).
There are three buttons on the back you use the up/down buttons to choose your character and then the Enter button to accept the character into your message.
current draw varies, but about 4-5ma MAX, so a 2032 battery (220mah) should last over 48 hrs.
.Where did you get this number? LEDs can draw up to ~25mA so considering that these arent that bright, that there are more than one on at once, and there is a chip to power (minimal) I'd think the battery would only last a few hours.
