The Alkaline batteries and lithium batteries are also appropriate for 9V smoke detectors and other 9V products.

Here are the common types of Smoke Detector batteries you can replace your old batteries with:

Alkaline 9V Battery

This is an industry favorite 9-volt battery for battery-operated smoke detector from a mega-brand. It is one of the very best 9v batteries for smoke detectors and also a great option for wireless microphones, guitar pedals, in-ear monitorsradios, security backup systems, and other 9V products.

The only difference between the Energizer Industrial and what you will find in most stores is the way it’s been packaged. Industrials come in cardboard boxes rather than the annoying blister packaging. Although these are cheaper, easy to use, and every bit as powerful as the Energizers you will find hanging on the hooks at checkout. It’s a low-cost replacement battery.

9V has been the most accepted battery of choice for smoke detectors for years now.kind of Battery for Smoke Detector

1.5V Super Heavy Duty 9V Battery

The 1.5V super heavy duty 9V battery is an ever-ready authentic smoke detector battery. It’s very cost-effective and perfect to purchase in bulk and have a pile in your closet or somewhere to swap in every 6 months.

The replacement frequency is quite high because the shelf life is not as long as other higher quality batteries, but for homeowners willing to climb up on a ladder or stool more often, then the Eveready 1222 is a solid option to save a few bucks. It’s suitable for smoke alarms and CO alarms with a capacity of about 800mAh.kind of Battery for Smoke Detector

9V Advanced Lithium Battery

This is the most expensive, with the highest quality, longest life battery. They are super rugged and durable batteries used even in medical devices and high-tech alarm systems. A great option for difficult-to-reach places in the home like a high ceiling.

When changing the smoke detector’s battery, this is your best choice which you will never regret. You can try to save a few bucks buying other 9 volt batteries for easier spots and spend a bit more on a LA522 for the fire alarm installed in a corner above the stairs. The LA522 usually lasts a lot longer.

Although Energizer says it has a 10-year shelf life, we don’t recommend you wait that long before replacing it. The LA522 9V battery will last you safely for up to 6-7 years. However, always take precautionary measures and replace your smoke detector batteries more often as your budget allows you.kind of Battery for Smoke Detector

1.5V AA Lithium Batteries

It’s the longest-lasting AA battery available. It’s an upgrade from standard alkaline AA batteries. AA Lithium batteries have a leak-free guarantee.
