Watch Battery Sizes Chart FAQ

You can use the Watch Battery Sizes Chart to find the right battery size for your watch. The chart lists the common battery codes, diameters, heights, voltages, and capacities for different types of watch battery. You can compare the battery code on your old battery or watch manual with the chart to find the matching size.

The different types of watch batteries are silver oxide, alkaline, lithium, and rechargeable. Silver oxide batteries are the most common and reliable type of watch battery. They have a stable voltage and a long lifespan. Alkaline batteries are cheaper but have a shorter lifespan and a lower voltage. Lithium batteries are more powerful and durable than silver oxide or alkaline batteries. They are suitable for watches that have high energy consumption or special features. Rechargeable batteries are eco-friendly and cost-effective. They can be recharged by solar power or kinetic energy.

You can know when to change a watch battery by looking for these signs:

  • The watch stops working or loses time accuracy.
  • The second hand skips several seconds or moves erratically.
  • The digital display fades or disappears.
  • The alarm, backlight, or other functions stop working.
  • The watch makes a beeping sound or shows a low battery indicator.

The lifespan of a watch battery depends on several factors, such as the type, size, quality, and brand of the battery, the type, model, and features of the watch, and the frequency and duration of use. Generally speaking, a silver oxide battery can last from 2 to 5 years, an alkaline battery can last from 1 to 3 years, a lithium battery can last from 5 to 10 years, and a rechargeable battery can last from 10 to 20 years.

You can extend the life of your watch battery by following these tips:

  • Store your watch in a cool and dry place away from heat and moisture.
  • Avoid exposing your watch to extreme temperatures or magnetic fields.
  • Turn off any unnecessary functions such as alarm, backlight, or chronograph when not in use.
  • Clean your watch regularly and remove any dirt or dust from the case back and battery compartment.
  • Replace your watch battery as soon as it shows signs of low power.
