This wiki has been updated 2 times since it was first published in August of 2019. Technology continues to advance, but the simple 9-volt battery is still an integral part of modern life. They’re commonly found in smoke and carbon monoxide detectors, as well as many handheld electronics and small toys, so it’s usually a good idea to keep a few at the ready. We've looked for both rechargeable and disposable models, so there are options for everyone, no matter the device or need. When users buy our independently chosen editorial choices, we may earn commissions to help fund the Wiki. Skip to the best 9v battery on Amazon.

Special Honors

Roost Smart 2.0 The Roost Smart 2.0 may be on the more expensive side, but it allows you to turn your existing smoke detector into a smart unit, so it’s worth the cost for many. Not only does it alert you if the alarm goes off, but it even lets you know when it’s running low on juice. getroost.com

Editor's Notes

August 17, 2019:

At this time, we have added most types of 9v battery, including standard alkaline options, although we’ve elected not to add any carbon zinc models (since alkaline batteries are generally a better bet when it comes to inexpensive disposables). Top choices come from the brands you’d expect, including ACDelco, Energizer, and Duracell. We especially like the long-lasting power of the Energizer Ultimate Lithium for smoke alarms, but the shape might make them hard to fit into some devices. As for rechargeable choices, the EBL NiMH or TalentCell Lithium Ion will work for many. The latter is incredibly portable and handy thanks to a micro USB port, which means you aren’t tied to any one specific charger. It has a higher upfront cost than some, but it should save you some cash over time.
