Energizer Max AAA Batteries (LR03) - 20 Pack

This is a maxi pack of twenty AAA alkaline cells from the Energizer Max range, supplied on a single hanging card. AAA is the slim 1.5 volt cylindrical cell, catalogued under the IEC code LR03 and sometimes called micro, and it is the size most small handheld electronics have settled on. Alkaline chemistry is the everyday workhorse: it holds its charge well in storage and delivers steady voltage across a wide spread of light and medium drains. The pack states a 10 year shelf life.

Twenty cells is a household quantity rather than a one-off replacement, which suits the way AAA actually gets used. Television and set top box remotes, wall clocks, wireless mice and keyboards, digital kitchen scales, children's toys, head torches and small LED book lights all take them, and most of those want two or four at a time. Keeping a full card in a drawer means a flat remote is a two minute job rather than a trip out. For a workshop, office or rental property, one card covers several devices at once.

Sold as one pack of twenty cells, with a minimum order of six packs in multiples of six, so the smallest order brings 120 cells. Keep them somewhere cool and dry in the card until needed, since alkaline cells self-discharge slowly at room temperature and that is what makes a long shelf life useful. Cells of different ages run down at different rates, so it is better to change a whole set together than to top up one cell in a pair. Spent alkaline cells belong at a battery recycling point rather than in the household bin; most supermarkets keep a collection box near the entrance. These sit alongside our wider Energizer range, which runs from AAAA and coin cells through AA, C and D to the 9V PP3.

How many cells do I actually receive?

One pack holds twenty AAA cells on a single hanging card, and the minimum order is six packs, which comes to 120 cells in total.

Is AAA the same thing as LR03?

Yes. LR03 is the IEC code for the alkaline AAA cell, and micro or R03 refer to the same physical size and 1.5 volt output.

My device asks for 1.5V AAA batteries, will these suit it?

They will. Alkaline AAA cells are nominally 1.5 volts each, so anything specifying 1.5V AAA, LR03 or micro takes this cell without an adaptor.

Can these be recharged?

No. Alkaline cells are single use and should not be put in a charger. If you want to recharge, you need rechargeable NiMH cells in the same AAA size.

How long can I keep spare packs before using them?

The pack states a 10 year shelf life. Keep the card somewhere cool and dry, away from radiators and direct sun, and the cells will be ready when needed.

What capacity in mAh do these cells hold?

The manufacturer does not state a capacity figure for this pack. Real runtime depends so heavily on the device and how hard it draws that a single number would mislead.
