How do I replace a battery in my cookware (generation 2 - with a capsule "end cap")?

Hestan Cue cookware which include a capsule "end cap" (generation 2) require a AAA battery to power. A brand new battery can power the cookware for several months with normal usage. 

To insert or replace a battery:

1. Use your hand to twist off the capsule "end cap" until it is completely removed.
2. Insert a AAA battery with the "negative" end (−) going in first. The positive end (+) should be facing in the capsule end cap's direction.
3. Replace the capsule end cap and hand tighten until it locks into place.
