#LR44 BATTERY INSTALLATION CODE#

W may be used in high drain cameras, quartz watches, and calculators.

P means that the electrolyte is composed of potassium hydroxide.

SW may be used in low drain quartz watches without chronograph functions, alarm, or light.

S indicates that the electrolyte is made of sodium hydroxide.

No letter: means the electrolyte is organic.

The additional letters that appear in the designation type (W in this case) are indicative of the electrolyte used: Note: The indicated labels can change over time without prior notice Frequently Asked Questions What Do Letter Suffixes on Cell Batteries Mean?Ĭonsider an example like the SR44W, which denotes a silver-oxide battery. The IEC 6:2021 particularly provides the requirements, dimensions, designation and methods used to test batteries used for watches.

#LR44 BATTERY INSTALLATION CODE#

IEC 60086-3 is an international standard that defines battery cells using an alphanumeric code format. They're termed 'next-generation batteries,' given their potential to hold more energy, their safety mechanisms, and potentially reduced cost per unit. In addition to the ingredients packed in the cell, these batteries use oxygen from the air as a depolarizer. Zinc-air batteries have the highest capacity compared to others. Incorrect disposal of the battery pollutes the environment.įor example, the United States, through its Mercury Act of 1996, prohibited the use of mercury in favour of mercury-free alkaline batteries. Mercury-oxide batteries have stable voltage but are no longer used because of their toxic nature. They’re often used in medical instruments and precision devices. Silver-oxide batteries are known for their stable discharge. However, they provide less stable voltage and less capacity than their lithium and silver oxide counterparts. There are four major categories into which cell batteries are grouped: Alkaline BatteriesĪlkaline batteries match other battery types in terms of size. Today, we'll explore button cell batteries, their composition, and the different types. They possess a low self-discharge, which allows them to keep their charge for a long time (especially in cases of inactivity).

The negative terminal is insulated and forms the top cap.īutton cells are famous for their longevity.

The positive terminal is composed of stainless steel and lies at the bottom.

Its diameter ranges between five to 25 mm (0.197 to 0.984 inches), while its height dimensions are between 1 and 6 mm (0.039 to 0.236 inches). It’s a single-cell battery often used to power small devices like hearing aids and wristwatches.
