9V Batteries

A 9V battery, also known as a nine-volt battery, stands out with its distinctive rounded rectangular shape, setting it apart from the cylindrical design of other common standard batteries like AA, AAA, C, and D. Typically comprised of six individual cells enclosed in a single wrapper, 9V batteries are available in various chemistry types. The most common variants are carbon-zinc and alkaline batteries, as well as lithium-iron disulphide batteries.

Compared to smaller cells, a 9V battery is capable of providing the equivalent power of six AA cells. This compact nature makes it a practical choice for many applications, particularly those that require long-term power supply, such as smoke detectors.

Our comprehensive range of 9V batteries includes renowned brands like Duracell, Energizer, Ansmann, Panasonic, RS PRO, and Varta, among others. If you're interested in rechargeable 9V batteries, we also offer a selection for your consideration.

What are 9V batteries used for?

9V batteries find wide utility in long-lasting applications that demand substantial power due to their high energy capacity. They serve diverse industries, ranging from medical to security.

While initially developed for transistor radios, 9V batteries continue to be employed in handheld devices, including test and instrumentation devices. These batteries prove especially useful in devices with backlit LCD displays, where their reliable performance ensures consistent operation.

Thanks to their long performance life, 9V batteries are often employed in applications that may remain dormant for extended periods, even in extreme environmental conditions. The moisture-resistant wrappers surrounding these batteries safeguard them from adverse elements. They are commonly found in safety devices such as security sensors, smoke alarms and detectors, emergency beacons, and monitoring devices.

The extended lifespan of 9V batteries means they require replacement less frequently than smaller cells. This characteristic makes them ideal for environments where hygiene is of utmost importance. Consequently, medical devices and equipment, including surgical lighting, data recorders, select patient monitors, and various medical instrumentation, frequently rely on 9V batteries to ensure continuous and reliable power supply.

With their versatility, high energy capacity, and long performance life, 9V batteries have established themselves as a dependable power source for an array of applications across multiple industries.
