What kind of battery you need for watch

by

The type of battery needed for a watch will depend on the specific model and features of the watch. Most modern watches use one of two types of batteries: lithium-ion batteries or quartz batteries.

Lithium-ion batteries are rechargeable batteries that are commonly used in smartwatches and other devices that require a lot of power. They have a higher energy density than other types of batteries, which means they can store more energy in a smaller size. They also have a longer lifespan than other types of batteries. Some brands are as follows:

  • Panasonic CR123A Lithium Battery
  • Makita BL1820B-2 18V Compact Lithium-Ion 2.0Ah Battery
  • Duracell CR2032 3V Lithium Battery
  • AmVolt- Pack of 12 CR2032 Batteries, 220mAh 3 Volt Lithium Battery
  • Energizer L91BP-4 Ultimate Lithium AA Batteries
  • EGO Power+ BA1400 56-Volt 2.5Ah Lithium-Ion Battery

Quartz batteries, also known as silver oxide batteries, are commonly used in traditional analog watches. They are non-rechargeable and have a relatively long lifespan (1-2 years) compared to other types of batteries. They are also relatively inexpensive and easy to replace. Some brands are as follows:

  • Maxell 371 (SR920SW) Silver Oxide 1.55V
  • Murata 377 (SR626SW) 1.55V Silver Oxide
  • Duracell 377 (SR626SW) Silver Oxide 1.55V (1 PC)
  • Energizer 377-376 Battery (SR626SW) Silver Oxide 1.55V (1PC)
  • Sony 377 (SR626SW) 1.55V Silver Oxide

Coin cell batteries: These are small, circular batteries that are often used in slim watches, fitness trackers, and other small electronic devices. They are non-rechargeable and have a relatively short lifespan (1-2 years) but they are inexpensive and easy to replace. Some brands are as follows:

  • Panasonic CR2032 3.0 Volt Long Lasting Lithium Coin Cell Batteries
  • Energizer 2032 Batteries, Lithium CR2032 
  • Duracell CR2032 3V Lithium Battery
  • Amazon Basics CR2032 3 Volt Lithium Coin Cell Battery

Solar powered batteries: These are batteries that are charged by exposure to light, and are commonly used in solar-powered watches and other electronic devices. They have a longer lifespan than other types of batteries, and do not need to be replaced as often. Some brands are as follows:

  • Sun Power Sun Vault
  • Tesla Powerwall 2
  • Sonnen Eco
  • Enphase IQ 
  • Generac PWRcell
  • LG Chem RESU
  • Panasonic EverVolt
