Description
A pack of four 9V alkaline cells from Duracell's Plus Power range, carrying the codes 6LR61 and MN1604. The 9V is the small rectangular cell, usually called a PP3, with both terminals on one top face: a stud and a socket that a clip pushes onto. Inside, a 9V alkaline cell is six 1.5V cells wired in series, which is why it feels heavier than its footprint suggests. Alkaline is the everyday chemistry for this size, and it is a primary cell: once flat it is replaced rather than recharged.
The 9V has a short but stubborn list of jobs. Domestic smoke and heat alarms are the main one, and most take a single PP3 behind a hinged cover. It also turns up in guitar and bass effects pedals, active pickups, multimeters, wireless microphone belt packs and older intercoms and doorbells. Four cells in one purchase suits a house with several alarms to see to on the same afternoon, or a musician who keeps spares in a pedalboard case. If you are unsure what your device takes, look at the connector rather than the label: a 9V clip is unmistakable.
Both terminals sit side by side on one face, so a loose 9V rattling about with keys and coins can short across them. Keep the cells in the pack until you need them, and tape the terminals of a spent one before it goes for recycling. Avoid mixing a fresh cell with a part-used one in a device that takes two. The pack carries a 100% life guaranteed claim. One purchase is a single pack of four cells; the minimum order is 8 packs, sold in multiples of 8, so 32 cells in all. Our wider Duracell range also runs to lithium coin cells, silver oxide watch cells and alkaline coin cells.

Frequently Asked
Is this the right battery for a smoke alarm?
Most domestic smoke and heat alarms that take a replaceable battery use a single 9V PP3, which is this cell. Check the label inside your alarm's battery cover to confirm before you buy.
What do 6LR61, MN1604 and PP3 mean?
They are all names for the same 9V rectangular cell. 6LR61 is the international alkaline code, MN1604 is Duracell's own reference and PP3 is the older British name still widely used.
Can these be recharged?
No. These are alkaline primary cells, so each one is used once and then replaced. Rechargeable 9V cells use a different chemistry and are bought separately from these.
How many cells do I actually receive?
One unit of this listing is a pack of four 9V cells. The minimum order is 8 packs, sold in multiples of 8, which works out at 32 cells in total.
How long will they keep in a drawer?
The manufacturer does not state a shelf life for this pack, so we do not quote one. Keep them dry, at room temperature, in the pack and away from loose metal.
Will this power a guitar effects pedal?
Yes, where the pedal is specified for a 9V battery and has a PP3 clip inside. Many pedals also take a mains adaptor, so check the pedal's own input rating.
