Do battery operated clocks stop working?
When battery operated clocks stop working, it's usually caused by one or more of the batteries. Either a battery has lost its charge, or battery acid has leaked, causing corrosion. Often, the internal mechanisms, such as the cogs, springs and other movements of the clock, are not faulty and are unaffected.
How long does a battery powered clock last?
An average AAA alkaline battery contains about 1000 milliamp-hours, so therefore, the batteries would last a maximum of 9.09 hours. This is assuming perfect conditions. In reality, you can probably deduct about an hour from that rating, as the battery will not be 100% efficient as it becomes discharged.
