Description
This card holds three JCB 9V alkaline cells, the rectangular block with two snap studs on top that clips onto a press-fit connector rather than sitting in a sprung compartment. The cells are coded 6LR61 on the body, and the card also prints MN1604, so if an equipment manual quotes either code you have the right cell in front of you. The same size is widely listed as PP3. The pack is printed Super Alkaline and Built to Last, and claims up to seven times more power, with an asterisk the front of the card does not explain.
Nine volt is the size most battery-only smoke and heat alarms take, along with carbon monoxide alarms, and it is the cell behind multimeters, guitar effects pedals, radio microphone packs, electronic drum modules and many intruder alarm bell boxes. Three on a card suits a house where the alarms all went in together and now want changing together: replace the set on one date you can remember rather than chasing a chirp at two in the morning. Store the spares at room temperature and away from loose keys and coins, because on a nine volt the two terminals sit close together on the same face.
Alkaline is a primary chemistry, so these cells are used once and replaced; they will not recharge and should never go into a charger. The card prints no shelf life figure, so we do not quote one. One unit of this listing is a card of three cells, and the minimum order is 12, sold in multiples of 12, which comes to 36 cells for a maintenance store or a managed building. It sits alongside our other JCB sizes, including AAA, AA, D and AAAA, plus JCB CR2032 and LR44 coin cells and rechargeable AA.

Frequently Asked
Will this fit my smoke alarm?
If the alarm takes a rectangular nine volt block that snaps onto a two stud connector, yes. Take the old cell out first and check it reads 9V, 6LR61 or PP3 before ordering.
Is 6LR61 the same as PP3 or MN1604?
They are all names for the same nine volt block. The cells here are marked 6LR61 and the card prints MN1604, so either reference in your manual points to this size.
Can I recharge these cells?
No. Alkaline is a single use chemistry, so fit them, run them down and replace them. Putting them in a nine volt charger is not something we would ever advise.
How long will one cell run my device?
JCB does not print a runtime on this pack, and it would depend entirely on the current your device draws. A smoke alarm sips power; a radio mic transmitter or a busy pedal board will not.
How many cells do I receive in total?
One unit is a card of three cells. The minimum order is 12 units in multiples of 12, so a first order brings 12 cards, which is 36 cells.
Can I fit these in a guitar pedal with a battery clip?
Yes, provided the pedal uses the standard nine volt snap clip. Unplug the lead when the pedal is idle, because many circuits keep drawing current while a jack is inserted.
