Door Chime Battery

Just changed the battery of the remote for the door bell ($1.70)

So this is a Lead-Mercury bettery, 12V.

Wonder when is the next time I need to replace this again. Can't remember how long the previous battery lasted.
Update: Sep 28 2016

The battery ran out of juice today! So it lasted less than 2 years.
