What's up with "the timer" battery indicator?

[Smart]

The timer has a 6 volt battery in the back and needs to be replaced about every couple years, but bring a small screw driver

Mine is AA

They are AA and they don't have to be replaced. On the newer ones you don't need a screw driver either. There is a latch on the bottom that can be turned with a coin.

Funny...I was thinking to myself "This thing sure doesn't seem to be holding a charge..."

Just picked mine up earlier this week from Ultramatic. Glad I read this before I head to Junction tomorrow.
