Description
This is a 9V alkaline cell from the JCB Industrial range, the familiar rectangular block with the two snap terminals on the top face that most appliances label PP3. It is priced and sold per cell rather than by the box, so the figure on the page is the cost of one battery, and the minimum order is ten. The retail pack states 0% mercury and cadmium. Alkaline is the standard general purpose chemistry for this format, which is why it is what nearly every 9V appliance in a British home is designed around.
The PP3 shape has stayed unchanged for decades, so the list of things that take one is long: standalone smoke and heat alarms, carbon monoxide detectors, digital multimeters and moisture meters, guitar pedals and active pickups, radio microphones and belt packs, garden irrigation timers, wireless doorbell transmitters and older alarm sounders. If the compartment has a pair of press stud contacts rather than a spring at one end and a flat plate at the other, it wants this cell. Ordering ten at a time suits a workshop, a rehearsal room, a site van or anyone servicing the alarms in several properties.
There is no polarity to work out with a PP3, because the studs only mate one way round: it either clips on or it does not. Changing every alarm in a building on the same day leaves you with a single date to remember rather than five. Keep spare cells in their packaging and away from loose coins and keys, since a 9V carries both terminals on one face and can short against metal in a drawer. The pack does not print a shelf life figure, so we do not quote one. We stock other JCB cells beside this one, including AA, AAA, AAAA and D alkalines, rechargeable AA and lithium coin cells.

Frequently Asked
Is a PP3 the same thing as a 9V battery?
Yes. PP3 is the common name for the rectangular 9V cell with the two snap studs on the top face, and the two terms are used interchangeably.
How many cells do I get for the price shown?
One. This listing is priced and sold per cell, and the minimum order is ten cells, bought in multiples of ten.
Will it fit my smoke alarm?
If the alarm takes a 9V PP3, yes. Open the compartment and look for the two press stud contacts on a short lead; that is the fitting this cell clips onto.
Can these be recharged?
No. Alkaline cells are single use by chemistry, so once a cell is flat it goes to a battery recycling point rather than back on charge.
Does the manufacturer state a shelf life?
The retail pack does not print a shelf life figure, so we do not quote one here. The pack does state 0% mercury and cadmium.
Why would I buy ten at once?
Most 9V uses are alarms and test gear spread around a building, so a batch lets you change them all on one date and keep spares to hand.
