9V ALKALINE BATTERY (HW/HIW)

A 9V alkaline battery is a type of non-rechargeable battery commonly used in various devices.

It provides a nominal voltage of 9 volts and is often used in items such as:

• Smoke detectors
• Radios
• Walkie-talkies
• Toys
• Pedal boards for musical instruments
• Certain medical devices
• Remote controls

Key Features:

• Voltage: 9V (nominal), which is higher than common AA or AAA batteries (1.5V each).
• Chemistry: Alkaline batteries use an alkaline electrolyte, typically potassium hydroxide, which is more stable and has a longer shelf life than zinc-carbon batteries.
• Capacity: Alkaline 9V batteries generally have a capacity of around 500–600 mAh (milliampere-hours), though it can vary based on the brand and specific battery design.
• Size: These batteries are typically rectangular, about 48.5 mm (1.9 inches) long, 26.5 mm (1.04 inches) wide, and 17.5 mm (0.69 inches) thick.

Advantages:

• Long Shelf Life: These batteries can last for years if not used, often up to 5–7 years.
• Widely Available: 9V alkaline batteries are easy to find in most electronics, hardware, and convenience stores.
