Description
This is a single 9V alkaline cell from the JCB Ultra Alkaline range: the rectangular block with two snap terminals at one end that most people know as a PP3. Its formal code is 6LR61, and PP3, 6LR61 and plain 9V all name the same cell, so if your device or its manual quotes any one of those, this is the right size. The 6 at the front of 6LR61 tells you what is inside: six small alkaline cells wired in series within one shell, which is where the nominal nine volts comes from.
Nine volt cells do one job in most homes: they sit in the smoke alarm. They also turn up in heat and carbon monoxide alarms, multimeters and test meters, guitar pedals and active pickups, wireless microphones and beltpacks, radio remote controls, and older transistor radios. Because alarms live on a ceiling and meters live in a drawer, a spare in the cupboard is worth far more than it costs on the day the alarm starts chirping. One thing to check before ordering: a handful of devices call for a 9V lithium rather than an alkaline, and this listing is the alkaline version.
The pack prints the Ultra Alkaline name alongside a 10x claim of up to ten times more power. That claim is asterisked and names no comparison cell, so we pass it on as the manufacturer's wording rather than a tested figure. The pack prints no shelf life figure. One unit is a single cell on a blister card, and the minimum order on this line is ten units, sold in multiples of ten, which suits a shop counter or a maintenance store. It sits alongside our wider JCB battery range, which runs from AAAA, AAA and AA through D to coin cells, and includes further 9V cells in Industrial and Super Alkaline.

Frequently Asked
Is a PP3 the same thing as a 9V battery?
Yes. PP3, 6LR61 and 9V are three names for the same rectangular cell with a press stud and a socket at one end, so any of them points to this size.
Will it fit my smoke alarm?
Most battery smoke and heat alarms sold in the UK take a 9V PP3. Open the battery tray and look for the snap connector; if it has one, this is the cell it wants.
How long does a 9V cell last?
The manufacturer prints no runtime figure, and it would depend on the device in any case. An alarm on standby draws very little, while a guitar pedal left switched on will drain a cell quickly.
Can I recharge it?
No. This is an alkaline cell meant for single use, so it should never go into a charger. The JCB rechargeable cells we stock are a separate line, in AA size.
How many cells do I actually get?
One. A single 9V cell comes on a blister card, and the minimum order is ten of those units, sold in multiples of ten, so ten cells in total.
What does the 10x on the pack mean?
It is the manufacturer's own claim of up to ten times more power, printed with an asterisk and no comparison cell named, so we report it as their wording and nothing more.
