Description
Eveready's 6V zinc battery is the tall rectangular block that powers lanterns and work lamps. The maker lists the cell as PJ996 and the pack prints 4R25 and 996; all three codes name the same battery, and lamp makers quote whichever standard they follow. Six volts from a single unit means no tray of four cells to line up and no weak cell dragging the rest down. A coiled spring terminal stands on the top face, ready for the contacts inside a lamp base to press against it. The pack also states 0% mercury and cadmium.
The 6V spring top block is long established in hand lanterns, inspection lamps and the amber warning lamps seen around roadworks, as well as older camping and fishing lamps. If your lamp has a deep base with sprung contacts in the lid, this is the cell it was built around. The quickest check is the old battery: look on its label for PJ996, 4R25 or 996, and confirm the 6V figure. Shape matters as much as voltage here, because the lamp body is moulded closely around the block. Eveready does not publish dimensions for this cell, so with an unfamiliar lamp, compare the old battery against the new one before the lid goes on.
Zinc cells are single use, so this one is replaced rather than recharged. Cells of this chemistry also recover a little between uses, which suits the on and off duty of a lantern or a site lamp better than a long continuous heavy drain. No shelf life or capacity figure is printed on the pack, and the manufacturer does not state either. One unit is one battery; our minimum order is 12, sold in multiples of 12, which suits a site store or van stock rather than a single replacement. It sits alongside our other Eveready cells, including AA, AAA, C, D and 9V sizes and CR2032 and LR44 coin cells.

Frequently Asked
Which lamps take this battery?
Hand lanterns, inspection lamps and the amber warning lamps used around roadworks typically run on the 6V block. Check the old cell for PJ996, 4R25 or 996 before ordering.
Are PJ996, 4R25 and 996 the same thing?
Yes. They are three naming conventions for one 6V cell, and the retail pack prints 4R25 and 996 alongside the voltage, so a lamp quoting any of them takes this battery.
Do I need a holder or four separate cells?
No. The full 6V comes from this one block, so there is no tray, holder or set of smaller cells to line up inside the lamp.
Can it be recharged?
No. Zinc cells of this kind are single use, so the battery is fitted, run down and then replaced rather than put back on charge.
How long will it run?
Eveready prints no capacity or runtime figure on the pack, and runtime varies with the bulb your lamp uses, so we quote no hours here.
How many do I have to buy?
Each unit is one battery, and the minimum order is 12, sold in multiples of 12, which works well as a van or site store holding.
