Frequently Asked Questions

In 1957, we helped make watch-winding a thing of the past by introducing the first watch battery.  We’ve made batteries for every small electronic device that’s come along since then: car alarms, digital thermometers, PDAs, handheld games and more.  And we’re always striving to make them stronger and more reliable.
