The LR6 (AA) alkaline cell is probably the most widely used battery format in the world. It powers remotes, torches, wireless keyboards, toys, cameras and portable medical devices. Yet many buyers still choose it by price alone and never check what its numbers mean in practice. This guide covers what an LR6 battery is, how to read its specification honestly, how long it will really last, and what to check when sourcing it in volume.

Most confusion starts with naming. The same cell is sold under several labels, and one look-alike label refers to a different chemistry entirely.
| Label | Meaning | Practical note |
|---|---|---|
| LR6 | IEC designation for an AA alkaline cell (the "L" indicates alkaline) | The correct term for export documents and technical specifications |
| 15A | ANSI designation for the same cell | Common in North American catalogues |
| AA | Common trade name for the size | Says nothing about chemistry, so always confirm LR6 versus R6 |
| R6 / R6P | Same size, but carbon-zinc chemistry | Lower cost and lower capacity; see AA R6P |
| HR6 | Same size, but rechargeable NiMH (about 1.2 V) | Not a like-for-like replacement in every device |
The table below reproduces the published data for HW Energy's LR6 cell.
| Parameter | Value |
|---|---|
| Designation | LR6 (IEC) / 15A (ANSI) |
| Positive active material | Manganese dioxide (EMD) |
| Negative active material | Zinc (Zn) |
| Shell material | Steel can |
| Height | 49.2 – 50.5 mm |
| Diameter | 13.5 – 14.5 mm |
| Weight | Approx. 23 g |
| Nominal voltage | 1.5 V |
| Operating temperature | -20 °C to 45 °C |
| Capacity | 3000 mAh |
| Test condition | 10 mA, 24 h/day, 20 °C, end voltage 0.8 V |
Three lines in this table deserve a closer look:
Capacity in mAh divides neatly into hours only in theory. Two effects make real runtime shorter than the arithmetic suggests, and the shortfall grows with current draw:
| Average current | Ceiling | Typical device | Reading the result |
|---|---|---|---|
| 10 mA | 300 h | Wireless mouse, small remote | Closest to the rated figure |
| 50 mA | 60 h | Portable radio, LED lantern | Expect noticeably less than the ceiling |
| 100 mA | 30 h | Toys, small torch | Cutoff voltage starts to matter |
| 250 mA | 12 h | Game controller, speaker | Real result can fall well below the ceiling |
| 500 mA | 6 h | Camera flash cycling, motors | Test your own device before committing to volume |
The ceilings are arithmetic, not measured results for any specific product. The practical lesson is to compare batteries by testing them in your own device at its real average current, not by comparing mAh figures on packaging.
| Application | LR6 suitability | Reason |
|---|---|---|
| Flashlights, portable lighting | Strong | Moderate steady draw, and a flat voltage curve keeps light output stable |
| Wireless keyboards and mice | Strong | Long runtime between changes |
| Toys and game controllers | Strong | Frequent high-current bursts favour alkaline |
| Emergency kits | Strong | Long shelf life for cells that may sit unused for years |
| Wall clocks, basic remotes | Acceptable, often unnecessary | Very low drain, so a lower-cost R6P may deliver better value |
| High-power tools, sustained motors | Limited | Consider rechargeable or lithium primary chemistry |
Not sure whether alkaline is worth the extra cost for your device? HW Energy's guide How To Choose Between Alkaline And Carbon Zinc Batteries compares the two chemistries by drain level, shelf life and cost per use.
Leakage is the failure users remember, and most cases trace back to how cells were stored or used. HW Energy explains the mechanism (internal gas pressure exceeding seal strength) in Battery Leak Prevention Technology. These are the habits that lower the risk:
| Situation | Do this | Why |
|---|---|---|
| Multi-cell devices | Replace all cells together; never mix old with new, or brands and chemistries | The weakest cell can be driven into reversal and vent gas |
| Devices stored for months | Remove the batteries | A small standby drain can push cells into deep discharge |
| Warehouse or home storage | Keep in a dry place below 25 °C, away from sunlight | Heat accelerates internal gas generation |
| Loose cells in a drawer or bag | Keep in original packaging, away from coins, keys and other metal | Metal contact causes a short circuit |
| A cell has leaked | Wear gloves, remove the cell, and clean the contacts once dry | Alkaline electrolyte is caustic and irritates skin and eyes |
For distributors, brand owners and device makers, the cell matters, and so does the factory behind it. Here is what HW Energy publishes about its own capability, so you can compare any supplier against the same questions.
| Area | Published information |
|---|---|
| Investment and experience | US$50 million investment from HW International Singapore; over 30 years of industry expertise (company profile) |
| Location and scale | Hai Phong, Vietnam; 55,000+ m² floor area; every cell carries the "Made in Vietnam" mark |
| Capacity | 14 high-speed intelligent lines; over 2 billion cells per year (smart manufacturing) |
| Quality control | More than 50 inspection steps from incoming material to dispatch, with online monitoring on production and packaging lines |
| R&D | Two R&D centres of about 2,500 m² with 200+ instruments; 50+ product technology patents |
| Certifications shown | ISO 9001, ISO 14001, C-TPAT and WCA (see certification) |
| Raw materials | Sourced from Belgium, France, Japan, South Korea, China and Vietnam |
| Lead time (FAQ) | First order valid for 90 days; repeat orders valid for 60 days |
The LR6 page lists eight packaging formats. The customization service follows five stages: jacket and packaging design, sample confirmation, production, quality inspection and delivery.
| Format | Typical channel |
|---|---|
| Blister card / blister pack | Retail shelves and hang displays |
| Paper card / paper box | Retail and gift packs; all-paper options suit plastic-reduction goals |
| Shrink wrap | Economical multipacks |
| Plastic box | Storage-friendly and reusable packs |
| Industrial packaging | Bulk supply to OEM and institutional buyers |
Yes. LR6 is the IEC code for the AA-size alkaline cell, and 15A is the ANSI code. "AA" alone does not tell you the chemistry, so check the code on the label.
Usually yes, because the size and contacts are the same. The voltage differs, though: alkaline cells start at about 1.5 V and NiMH cells at about 1.2 V. Check the device manual before swapping. Never try to recharge a standard alkaline cell.
Choose LR6 for medium and high-drain devices, cold conditions and long storage. Choose R6P for very low-drain items where cost matters most. The comparison guide linked in section 4 explains the trade-off.
Yes. The alkaline range also includes AAA LR03, C LR14, D LR20 and 9V 6LR61. The full lineup is on the alkaline batteries page.
An LR6 alkaline cell is easy to buy but not trivial to buy well. Read the label code, treat the 3000 mAh figure as a light-load benchmark, match the chemistry to your device's real current draw, and store cells cool and dry. For volume supply, ask for the test conditions, traceability and certifications behind the cell.
