AAA battery
open-in-new
<h2 id="use">Use</h2> <p>AAA batteries are most often used in small electronic devices, such as <a href="/facts/Television/X4YG5nT1">TV</a> remote controls, <a href="/facts/MP3_player/QHTLMGu4">MP3 players</a> and digital cameras. Devices that require the same voltage, but have a higher current draw, are often designed to use larger batteries such as the <a href="/facts/AA_battery/BkH5cBuW">AA battery</a> type. AA batteries have about three times the capacity of AAA batteries. With the increasing efficiency and miniaturization of modern electronics, many devices that previously were designed for AA batteries (remote controls, cordless computer mice and keyboards, etc.) are being replaced by models that accept AAA battery cells. </p><p>As of 2007, AAA batteries accounted for 24% of alkaline primary battery sales in the United States. In Japan as of 2011, 28% of alkaline primary batteries sold were AAA. In Switzerland as of 2007, AAA batteries totaled 30% of primary battery sales and 32% of <a href="/facts/Secondary_battery/A6zUkPkW"> secondary battery (rechargeable)</a> sales.<a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a><a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a><a class="footnote-ref" id="fnref:5" href="#fn:5"><sup>5</sup></a> </p> <table><tbody><tr><th><a href="/facts/Comparison_of_commercial_battery_types/SezHF0jT">Chemistry</a></th><th>IEC name</th><th>ANSI/NEDA name</th><th>Nominal <a href="/facts/Voltage/EN2po6N2">voltage</a> (V)</th><th>Typical capacity (<a href="/facts/MAh/H8qKSLtk">mAh</a>)</th><th>Typical capacity (<a href="/facts/Kilowatt_hour/qvVkEmPH">Wh</a>)</th><th>Rechargeable</th></tr><tr><td><a href="/facts/Zinc%E2%80%93carbon_battery/MDC00Uuh">Zinc–carbon</a></td><td>R03</td><td>24D</td><td>1.5</td><td>540</td><td>0.81</td><td>No</td></tr><tr><td><a href="/facts/Alkaline_battery/gL5XUWo4">Alkaline</a></td><td>LR03</td><td>24A</td><td>1.5</td><td>860–1,200<a class="footnote-ref" id="fnref:6" href="#fn:6"><sup>6</sup></a></td><td>1.3–1.8</td><td><a href="/facts/Rechargeable_alkaline_battery/V318FKC3">Some</a></td></tr><tr><td><a href="/facts/Lithium_battery/D5yfo8XS">Li-FeS2</a></td><td>FR03</td><td>24LF</td><td>1.5</td><td>1,200</td><td>1.8</td><td>No</td></tr><tr><td><a href="/facts/Nickel%E2%80%93metal_hydride_battery/EvCG8loy">NiMH</a></td><td>1⁄2 AAA 10.4mm 22.7mm</td><td>GP35AAAH</td><td>1.2</td><td>~350–1,000<a class="footnote-ref" id="fnref:7" href="#fn:7"><sup>7</sup></a></td><td>0.42 -
