Duracell Procell Intense AAA Batteries (LR03) - 10 Pack

These are AAA alkaline cells from the Procell Intense line, supplied as one retail box of ten. Each cell runs at 1.5V, the standard alkaline voltage, and carries the international code LR03 alongside the older names Micro and Mini Stilo that some equipment manuals and battery compartments still print. The retail pack is marked for high drain devices, which is the job this line is built around: kit that pulls hard in short bursts rather than trickling along quietly for months. The box carries an open and close tab, so the cells you have not fitted yet stay together in a drawer or a toolbox instead of rolling loose.

This is the size for anything small that does real work. Wireless microphones and belt packs, digital callipers, blood pressure monitors, computer mice and trackpads, remote controls, door chimes, game controller pads, head torches and the little LED inspection lamps that live in a van. Buying ten at a time suits a venue, a workshop, a school, a hire company or simply a busy house that gets through cells steadily and would rather not run out mid job. Before ordering, check the compartment inside your device for the letters AAA or the code LR03; an AA cell is noticeably fatter and longer and will not drop into an AAA holder.

One order brings you a single box of ten cells, and the minimum order on this listing is ten boxes, sold in multiples of ten. Alkaline cells are not rechargeable, so they should never go into a charger, and a part used set is best kept apart from a fresh one rather than mixed in the same device. The manufacturer prints no shelf life claim on this pack, so we quote none. It sits alongside our wider Duracell range, which runs from lithium coin cells such as CR2032, CR2025 and CR2016 to silver oxide watch cells and a AA and AAA charger.

How many cells do I actually receive?

One box holding ten AAA cells. The minimum order on this listing is ten boxes, sold in multiples of ten, so the smallest purchase is ten packs.

Is LR03 the same thing as AAA?

Yes. LR03 is the international code for an alkaline AAA cell, and Micro and Mini Stilo are older regional names for the same size and shape.

What does high drain mean for my device?

It describes kit that draws a heavy current in bursts, such as a wireless microphone, a motorised toy or a bright head torch, rather than a clock ticking along slowly.

Can I recharge these cells?

No. Alkaline cells are single use by chemistry and must not be put in a charger. If you want rechargeables, choose cells sold and labelled as rechargeable.

Can I mix them with the cells already in my device?

Replace the whole set at once. Mixing a fresh cell with a part used one leaves the older cell doing less work and shortens the run time you get.

Does the manufacturer state a shelf life?

No shelf life claim is printed on this pack, so we do not quote one. Store the cells somewhere cool and dry and keep them in the box until needed.
