Understanding LR44 SR44 Battery And 1632 Battery Energizer: A Comprehensive Guide

Batteries are the lifeblood of our everyday devices, powering everything from remote controls to watches and calculators. Among the myriad battery types available, the LR44 SR44 batteries and 1632 battery energizer options often come up in consumer discussions. This article delves into the specifics of these batteries, highlighting their features, applications, and differences to help you make an informed choice.

LR44 SR44 Battery

The LR44 SR44 battery options are small button or coin cells commonly used in small electronic devices. They are the best options and are famous for their small size and consistent power output. Despite their similarities in appearance and size, they have crucial differences, primarily related to their chemistry and performance characteristics.

LR44 Batteries

This is among the best battery options. It is part of the AG13 battery group, which includes A76, 357, and LR1154. These batteries are 11.6 mm in diameter and 5.4 mm in height, making them ideal for compact devices.

Characteristics and Applications

  • Voltage: The nominal voltage of an LR44 battery is 1.5V, which is standard for most small electronic devices.
  • Capacity: Typically, LR44 batteries have a capacity of around 110-130 mAh.
  • Cost: LR44 batteries are generally cheaper than their silver oxide counterparts, making them a popular choice for low-cost devices.
  • Applications: These batteries are commonly found in toys, calculators, laser pointers, watches, and medical devices like thermometers.

SR44 Battery

The SR44, the silver oxide battery, is part of the same size family as the LR44. Additional classifications consist of 357, SR1154, and G13. The chemical makeup is where the main distinction is found.

Characteristics and Applications

  • Voltage: The nominal voltage of an SR44 battery is slightly higher at 1.55V.
  • Capacity: SR44 batteries generally have a higher capacity, around 150-200 mAh, providing longer-lasting power.
  • Cost: SR44 batteries are more expensive than LR44 due to the silver oxide chemistry.
  • Applications: Given their longer life and stable voltage, SR44 batteries are preferred in precision instruments, high-end watches, medical devices, and cameras.

1632 Battery Energizer

The name 1632 comes from its dimensions: 16 mm in diameter and 3.2 mm in height. Because of its durability and high energy density, it is commonly employed in many different types of electronic gadgets.


  • Voltage: The 1632 Battery Energizer has a nominal voltage of 3V, double that of the LR44/SR44 batteries, providing more power to compatible devices.
  • Capacity: The typical capacity ranges from 120-140 mAh, offering substantial power storage given its size.
  • Shelf Life: One of the standout features of the CR1632 is its long shelf life, often exceeding ten years, thanks to the lithium chemistry.
  • Applications: This battery is commonly used in car key fobs, remote controls, medical devices, fitness trackers, and other compact electronic gadgets.

To Sum Up!

Understanding LR44, SR44, and 1632 batteries is important. This knowledge helps consumers choose the right battery. Employ well-informed decisions depending on your applications and demands. Always consider the device requirements, performance expectations, and environmental impact when selecting batteries to ensure optimal performance and sustainability.
