Description
Energizer's 9V Ultimate Lithium is a lithium cell in the standard rectangular nine volt format, with the familiar pair of snap terminals on top. The cell is coded L522, and the box also carries the 9B and E-Block markings used elsewhere in Europe, which is useful when you are matching against a code printed on the battery you are taking out rather than on a shop label. Lithium is a different chemistry from the alkaline cells most households keep in a drawer, and the most obvious difference in the hand is weight: a lithium nine volt is appreciably lighter than an alkaline one of the same size. The pack states a 10 year shelf life.
Nine volt cells live in a narrower set of devices than AA or AAA, and they tend to be the ones you least want to fail: mains linked and standalone smoke and heat alarms, carbon monoxide detectors, multimeters, radio microphones and belt packs, guitar pedals and older wireless doorbells. The size is commonly listed as PP3, and any holder built for that shape takes this cell, because the body dimensions and the terminal layout are fixed by the format. A pack of ten suits a building with several alarms to service in one go, a venue or school running a set of microphones, or a workshop keeping spares to hand.
One unit of this listing is ten cells. The minimum order is four units, sold in multiples of four, so the smallest order brings forty cells. With the 10 year shelf life printed on the pack, cells held in reserve stay worth fitting long after the first ones go in. We also stock Energizer in AA, AAA, C and D, in coin cells, and as a single 9V alkaline where ten is more than you need.

Frequently Asked
Will this fit anything that takes a PP3 battery?
Yes. The nine volt format is standardised on body size and on snap terminal spacing, so any PP3 holder accepts this cell.
What is the difference between this and an alkaline 9V?
The chemistry. This cell is lithium rather than alkaline, which makes it lighter for the same size, and the pack prints a 10 year shelf life. We also list an Energizer alkaline 9V as a single cell.
How many cells do I actually receive?
One unit of this listing is a pack of ten cells. The minimum order is four units, sold in multiples of four, so a first order is forty cells.
Is it suitable for a smoke or heat alarm?
Yes, provided the alarm is built for a nine volt cell. The long printed shelf life suits alarms and detectors that sit untouched for months at a time.
What do the codes L522, 9B and E-Block mean?
They are all names for the same nine volt size in different naming systems, so a device listing any one of them takes this cell.
