9 Volt Alkaline batteries

As you likely know, there are many battery options available. Different devices use different sizes of batteries, and you need to get sizes that are compatible with your security devices. In most cases, the battery to use with a piece of equipment depends on the size of the device and how much power needs to be supplied. Keep in mind that having to use a larger and bulkier battery can result in the entire device needing to be redesigned.

When it comes to 9 volt alkaline batteries, these devices are fairly small. However, they are still larger than a typical coin battery or other popular sizes like CR123A, AA and AAA. But a good thing about 9 volt alkaline batteries is that they tend to supply a decent amount of power. This makes them suitable for many applications. They can also be easily recognized for their medium rectangular design and the two terminals on the same end. Some people may also refer to 9 volt batteries as PP3 batteries.

For security sensors, 9 volt batteries are not commonly used. They are too large, and design changes would often need to be made, which would affect the appearance of these sensors. The amount of power they provide is often much greater than compared with what is needed for allowing these sensors to operate reliably for a longer period of time. For those reasons, most security sensors will use something smaller like a CR123A camera battery, AA batteries or AAA batteries. Very small sensors often use coin cell batteries like CR2032 and CR2025 batteries.

However, one application that is very popular for 9 volt batteries is in smoke detectors. Smoke detectors are commonly integrated with security systems, and a user may need 9 volt batteries to power these devices. Smoke detectors receive great benefits from 9 volt batteries for several reasons. For one, they are larger than most security sensors, and a larger battery won't interfere with the device's design. Additionally, the extra power will help them maintain a longer battery life. Other applications for 9 volt batteries include walkie-talkies and clocks.

The batteries listed on this page are all alkaline batteries. Alarm Grid recommends the use of lithium batteries, as they provide a longer power life and work more reliably. However, you can still use alkaline batteries in most situations. But users should not expect them to last as long in most situations. If possible, obtain lithium batteries for your smoke detectors.
