Description
This is a single Eveready Gold 9V alkaline battery, supplied on its own retail card. The 9V cell, widely known as a PP3, is a small rectangular block with two snap studs on the top face rather than contacts at each end, so it connects through a clip instead of a spring. Alkaline is the everyday chemistry for this size: it holds a steady voltage through most of its working life and copes well with the long, low draw that alarms and detectors ask of it. The body is gold with a black top.
A 9V is the cell people reach for when a device will not take AA or AAA. Standalone smoke alarms run on one, and mains linked alarms often carry one as the backup; carbon monoxide alarms frequently do the same. Beyond the hallway ceiling, the PP3 shape turns up in multimeters, guitar effects pedals and active pickups, wireless microphone belt packs, electronic keyboards and portable radios. If you are replacing one, check the old cell for the twin snap terminals on the top before you order, because every PP3 shares the same footprint and that shape is what decides fit.
The retail pack states that the battery is ready to use for up to five years, which makes it worth keeping a spare in the drawer before an alarm starts chirping in the small hours. One unit here is one cell, and the minimum order is 12 units, sold in multiples of 12, so it suits a landlord, a venue or anyone fitting out several alarms at once. Our wider Eveready Gold range covers AA, AAA, C and D alongside this 9V. Because the two terminals sit side by side on a 9V, store spares on their card rather than loose with coins and keys.

Frequently Asked
Will this fit my smoke alarm?
If the alarm takes a 9V PP3, yes. Lift the old cell out and look for the two snap studs on the top face, because that is the only fit check a 9V needs.
Is a PP3 the same as a 6LR61?
Yes. PP3 is the common name for the rectangular 9V cell, and 6LR61 is the code used for the alkaline version, so both describe this battery.
How many batteries do I actually receive?
One cell per unit. The minimum order is 12 units sold in multiples of 12, so a first order brings you twelve single batteries.
How long will it keep before I use it?
The pack states the battery is ready to use for up to five years, so a spare bought now should still be good when an alarm finally asks for it.
Can I recharge it?
No. This is a single use alkaline cell and should not be put on a charger. If you want a rechargeable 9V, look for a NiMH type instead.
Will it work in a guitar pedal or a multimeter?
Yes, both commonly take a 9V PP3. Alkaline suits the low, steady draw of a test meter well, and it is the usual choice for pedals too.
