Q. How long do quartz wall clock battery last?

Answer

High-quality quartz clock batteries can keep ticking for one year or more on a single charge. It's recommended that an investor invests in a Lithium battery (RS PRO 880-1558) to ensure long service life. The higher-quality movements use more robust polymers, greater precision during assembly, and more copper in the coil. While we have seen low-cost movements that only survive a few years, we have seen high-quality ones that span well over two decades. Whenever a user does the twice-yearly ritual of adjusting the clocks for Daylight Saving Time, it's a good idea to double-check for any signs of battery leaking. Quartz crystal oscillators are particularly precise since they generate a signal exactly 32768 times per second.
