A: Hi coffeedrinker....sorry you are having this issue. You can access the battery on the bottom center of the remote. Push the switch to the right and while doing this, slide out the case.
A: Hi defective...sorry you are upset, but it clearly states on the packaging the battery requirements and that they are not included. Most electronics do not include the batteries.
