![]() ![]() So, what is the reason that enables disposable batteries to last for several years?įirst and foremost, watches don’t require much energy to move the hands or show the digits. However, classic disposable batteries also have a considerably long lifetime. The reasons why solar and Kinetic watches last so long are clear to all – they can be charged repeatedly until the cells simply wear out. Like solar watch batteries, Kinetic capacitors last much longer than standard disposable batteries – their lifetime stays between 10 and 15 years. It’s a timepiece that charges itself from the motions of the wearer and accumulates the energy in a rechargeable cell called a capacitor. Seiko and Casio, on the other hand, offer solar pieces with an expected battery life of 10-15 years.Īnother type of watch that employs batteries is a Kinetic watch. For example, Citizen Eco-Drive solar watches come with rechargeable cells that last for 20-40 years. The timespan of battery lifetimes varies, depending on the technology. Therefore, the common conception that solar watches never require battery replacements is incorrect. ![]() However, nothing is eternal, and solar watch batteries will eventually lose their ability to store the energy at one point. Depending on the manufacturer, a typical full charge (power reserve) lasts anywhere between 6-12 months. It means that the cells have the ability to charge over and over again whenever there’s enough light. Unlike classic quartzes, solar watch batteries are rechargeable. But it applies to frequent use and not occasional exploitation.īesides standard quartz watch batteries, there are several other types of cells used in wristwatches, such as the ones in solar-powered watches. However, since digital watches are usually equipped with several functions that typically find good use by the wearer, the chances of draining the battery faster are pretty high. When comparing digital quartz watches with analog counterparts, there’s not a significant difference in the lifetime of batteries under normal use. ![]() The estimated 2-3 years is guaranteed under normal exploitation, with no overly excessive use of various features. However, that doesn’t mean the battery runs empty in a matter of months. Whether you reach the estimated length depends on how you exploit your quartz watch.įor example, if your watch has a stopwatch feature or an alarm and you’re a frequent user of those functions, the lifetime is inevitably shorter. When talking about the average result you can expect, quartz watch batteries have a lifespan between 2-3 years (24-36 months). ![]()
