Looks like a nicer screen and interface button arrangement than mine, though I rarely reprogram it, has worked great for a few years now and has two outlets for $13:
If it has the same battery setup as mine, it's a stack of welded NiCd coin cells, technically replaceable with a soldering iron but not considered user serviceable in the common sense.
This timer has a 4.5V internal rechargeable battery with a projected 10-year lifespan. When plugged into a household electrical outlet, the outlet provides power for the timer. When unplugged, the battery powers the memory of the digital timer for up to 6 months. The internal battery is not replaceable.

Thank you!
