9V Batteries.

Power for Safety and Instruments

The rectangular 9V battery is a workplace classic, best known as the “smoke alarm battery.” In addition to being a vital component in a building’s smoke detectors, it is widely used in measuring instruments (multimeters), wireless microphones, and certain portable devices. At Tingstad, you’ll find reliable 9V batteries in pack sizes suitable for both small offices and large property managers.

Important Choice for Smoke Alarms: Alkaline or Lithium?

For smoke alarms in particular—often mounted high up and hard to reach—battery life is crucial. Here’s what you should consider:

• Alkaline 9V (Standard): An affordable and dependable choice for most smoke alarms and handheld instruments. For maximum safety, it should be replaced annually.
• Lithium 9V (Long Life): Highly recommended for property owners and detectors placed in hard-to-reach locations. A lithium 9V battery can last up to 10 years, significantly reducing maintenance costs and time spent on battery replacements.
• Rechargeable 9V: Best suited for devices that consume more power and are used daily, such as wireless microphones in conference settings.
