Common Questions
Can anyone tell me if the batteries are the same size as standard 9 volts batteries or if they are longer?
They are a bit taller and fatter than some name brands, but within spec for size. It's a good idea to make sure your smoke detector is being replaced every 10 years.
Will they fit the standard fire/smoke alarms? Some comments say that the batteries are hard to install, but others say that they are longer than others.
I just installed 4 of the 9V Amazon batteries in smoke alarms, and they fit well.
How much ampere is used for a battery?
If subjected to high current they will suffer voltage depression, which is below the target range needed for a 9V battery. Try to keep the current under 80mA unless you just don't care about voltage droop.
The city requires that they have expiration dates listed on the battery, can anyone confirm that?
There are no dates on the items I just ordered, just a code number that might work for you, so if these are for smoke detectors, buy the Energizer Lithium 9 Volts as they last for 10 years.
Where do these batteries come from?
These are made in China according to the product details section.
