Panasonic Specialty 12V Battery (LRV08)

A single Panasonic LRV08, the 12V alkaline cell from the Specialty range, supplied on a one-cell blister card. The pack describes it as a micro alkaline battery, and micro is the operative word: the cell shown here is a slim cylinder, nothing like the fat round cells most households keep in a drawer, yet it delivers twelve volts where a standard alkaline round cell gives one and a half. Getting that voltage out of that little space is the whole point of the format, and it is why the code printed along the side of the cell matters far more than its rough shape does.

This is a specialist size rather than a household staple, so it is worth checking exactly what you are replacing before you order. Read the old cell rather than the device: the code runs along the body, and on this one it reads LRV08 in plain text. The retail card prints small icons for the device classes the manufacturer has in mind, among them a walking figure beside a sensor and a heart with a pulse trace, so the sorts of things that sit on a wall or in a pocket and draw a modest current over a long stretch. Alkaline is a primary chemistry, which means a cell of this kind is fitted, used and replaced rather than charged, so keeping a spare to hand is sensible for anything you would rather not find dead.

The front of the card carries 0% Hg added, so no mercury has been added to the cell. We sell this listing as one cell per unit, with a minimum order of ten units bought in multiples of ten, which suits keeping a small tray of them behind a counter or in a maintenance cupboard rather than buying one at a time. Other sizes in the Specialty range cover the same specialist ground.

Can I recharge an LRV08?

No. Alkaline is a primary chemistry, so the cell is fitted, used and then replaced. Charging a primary cell is not something to attempt.

How many cells do I actually receive?

One cell per unit of this listing. The minimum order is ten units in multiples of ten, so the smallest order brings you ten single cells.

Why is it 12V when it is so small?

That is the reason the size exists. A standard alkaline round cell gives one and a half volts, so devices needing twelve from a tiny space use a cell like this instead.

Which other battery codes is LRV08 the same as?

We are only given the LRV08 code by the manufacturer, so we list no cross-references. Read the code printed on the cell you are taking out and match it exactly.

Does it contain mercury?

The front of the retail card states 0% Hg added, which means no mercury has been added to the cell. Please recycle spent cells at a battery collection point.
