Place a bulk battery order. The industry favorite 9-volt battery for battery-operated smoke alarms from a mega-brand — this is one of the very best 9v batteries for smoke detectors.
Also a great option for wireless microphones, guitar pedals, in-ear monitors, radios, security back-up systems and all sorts of different uses. The only difference between Energizer Industrial and what you'll find in the store is the way it's packaged. Industrials come in cardboard boxes rather than annoying blister packaging.
These are cheaper, less of a hassle and every bit as powerful as the Energizers you'll find hanging on the hooks at checkout. A solid inexpensive option—perfect to buy in bulk and have a pile in the closet somewhere to swap in every 6 months or so.

Much of this will depend on the general and standby power consumption of the smoke alarm, the quality of the battery installed, the age of the battery installed and the temperature of the environment in which it is installed.
If your smoke alarm uses a lithium battery, it is inbuilt into the alarm and cannot be replaced. The entire unit needs to be replaced every 10 years. The batteries in these alarms are designed to last the life of the smoke alarm, in which case the battery will have served its purpose after 10 years.
Most alarms which contain a year-life lithium battery will have an in-built low battery warning like their 9-volt counterparts. When the lithium battery is low, they too will emit a quick chirp once every seconds. As mentioned above, these year-life lithium batteries are supposed to last at least 10 years, which is long enough to service the year life expectancy of the alarm.
However, if you find your lithium battery powered smoke alarm is chirping before it has reached 10 years of age, it often indicates a battery failure. If this happens, contact the manufacturer of the smoke alarm and organise the replacement of the whole unit if it is still under warranty, or otherwise have it replaced by an electrician or smoke alarm professional.
We are observing an increased trend in home owners choosing the year-life lithium battery-powered smoke alarms, or mains powered alarms with year-life lithium backup batteries.
This indicates that people are now showing a definite preference for the year lithium battery smoke alarms over the alarms which contain a removable 9-volt battery.
As mentioned above, these lithium battery alarms do not require the 9-volt battery to be replaced in each alarm every year. As discussed earlier, smoke alarms are designed to start beeping when the batteries are running low. This can cause your smoke alarm to make a chirping noise at times when smoke has not been detected. The fact that your alarm is beeping is a good sign — it means your device is still working well enough to detect the low battery power and let you know that a changeover is due.
This will silence the chirp for 24 hours, allowing you time to source and install a new battery. Not all smoke alarms are equipped with this feature. Give it time and have a little patience. Sometimes it may take a smoke alarm minutes to reset and acknowledge a new battery has been installed, before resuming normal operation.
How easy is it though, in the middle of replacing a battery, to be distracted by a small child speaking to you, your puppy grabbing your socks off the floor and running off with them, or a breaking news story on TV for example! Or perhaps you're trying to replace the battery in the middle of the night and you're groggy and don't know which way is up!
It might also be a good idea to check that there is no corrosion on the battery terminals. If there is, just use some fine sandpaper emery paper to give them a quick clean up. If corrosion is found on the battery terminals, clean it off using some fine sand paper prior to inserting the new battery. Maybe check the quality of the smoke alarm battery as well.
To rule out any doubt, try a new, fresh battery from another packet or from a different place of purchase. And hopefully I've been able to answer the question 'How often should smoke alarm batteries be changed? Did it help provide an answer you were looking for, or was there something I left out, and what did you find most helpful?
