Allegro 9V Battery, 987101F

The Allegro 9V Battery (Part Number: 987101F) is a standard 9V battery typically used in a variety of electronic devices, such as smoke detectors, portable meters, toys, and other low-power electronic applications. While specific technical details about the Allegro 987101F battery may not be widely available in the public domain, we can provide a general description based on common characteristics of 9V batteries and Allegro's typical product offerings.

Key Features of a 9V Battery (General):

1. Voltage: As the name suggests, this battery provides a nominal voltage of 9 volts. It's commonly used in devices that require a moderate amount of power over a sustained period of time.

2. Chemistry:

   • 9V batteries are commonly available in alkaline or lithium chemistries. Alkaline batteries are more common, but lithium batteries can offer higher energy density, longer life, and better performance in extreme temperatures.
   • Alkaline 9V batteries are widely used for everyday consumer applications due to their low cost, while lithium batteries tend to be more expensive but last longer and perform better in a wider range of environmental conditions.

3. Energy Capacity: A typical 9V alkaline battery has an energy capacity of approximately 500-600 mAh, though this can vary depending on the specific chemistry and manufacturer. Lithium versions can have a much higher energy density, potentially lasting longer under the same conditions.

4. Common Applications:

   • Smoke Detectors: 9V batteries are a popular choice for powering smoke detectors due to their long shelf life and reliability.
   • Electronic Test Equipment: Used in multimeters, handheld testers, and other portable diagnostic devices.
   • Toys and Gadgets: Widely used in small electronic toys, wireless devices, and other small, battery-powered gadgets.
   • Medical Devices: Used in medical monitoring equipment or emergency devices where portable, reliable power is required.
   • Other Low-Power Devices: Often found in clocks, remotes, LED lights, and more.

5. Design and Construction:

   • Size: A typical 9V battery has a rectangular form with a snap connector at the top for easy connection to circuits.
   • Terminals: The battery typically has two male terminals (one for positive and one for negative) that connect via the standard snap connector.
   • Durability: Typically, 9V batteries are constructed to handle normal operating conditions, but they should not be exposed to extreme heat or physical abuse.
