Each cell delivers 1.5V and is designed for low-drain, intermittent-use devices rather than high-current applications. Zinc carbon chemistry provides a lower cost per cell compared to alkaline equivalents, making these batteries a practical choice for devices that draw minimal power over extended periods.\u003c\/p\u003e\n\u003cp\u003eThese AAA cells suit wall clocks, basic remote controls, small LED torches, kitchen timers and children's toys with intermittent use patterns. They are less appropriate for high-drain devices like digital cameras, motorised toys or wireless computer peripherals, where alkaline or lithium cells would perform better. The 1.5V nominal voltage drops more steeply under load than alkaline chemistry, so runtime in moderate-drain devices will be shorter.\u003c\/p\u003e\n\u003cp\u003eThe blister pack measures 120mm x 83mm x 12mm and weighs 40g including packaging. Each cell is marked with the Panasonic branding and polarity indicators. The AAA size (also known as LR03, 24AU or X92 in alternative naming systems) is the second most common cylindrical battery size after AA, fitting devices with smaller battery compartments.\u003c\/p\u003e\n\u003cp\u003ePanasonic's zinc carbon range sits below their alkaline and lithium lines in performance and price. These batteries contain no added mercury, lead or cadmium. Once depleted, dispose of them according to local battery recycling guidelines rather than general waste.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.04\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWidth (mm)\u003c\/td\u003e\n\u003ctd\u003e120\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHeight (mm)\u003c\/td\u003e\n\u003ctd\u003e83\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDepth (mm)\u003c\/td\u003e\n\u003ctd\u003e12\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery Range\u003c\/td\u003e\n\u003ctd\u003ePanasonic Heavy Duty\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCell Size\u003c\/td\u003e\n\u003ctd\u003eAAA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCell Composition\u003c\/td\u003e\n\u003ctd\u003eZinc\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat devices are these batteries best suited for?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThese zinc carbon AAA cells work best in low-drain devices with intermittent use: wall clocks, basic remote controls, small torches, kitchen timers and simple toys. They are not recommended for high-drain devices like digital cameras, wireless mice or motorised toys, where alkaline or lithium batteries perform significantly better.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow do zinc carbon batteries differ from alkaline?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eZinc carbon chemistry costs less per cell but stores less total energy and performs less well under moderate to high current draw. Alkaline AAA batteries last longer in most devices and maintain voltage better under load, but cost more. Zinc carbon suits truly low-drain applications where the lower price justifies the reduced performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan these be recharged?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. Zinc carbon batteries are single-use primary cells and must not be placed in a battery charger. Attempting to recharge them can cause leakage, rupture or fire. For rechargeable AAA cells, use NiMH (nickel-metal hydride) batteries with an appropriate charger.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat are the alternative names for AAA batteries?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAAA batteries are also known as LR03 (IEC designation), 24AU, X92, MN2400, E92 and R03 depending on the naming standard. All these codes refer to the same physical size and 1.5V nominal voltage, though chemistry may vary (zinc carbon, alkaline or lithium).\u003c\/p\u003e","brand":"Panasonic","offers":[{"title":"Default Title","offer_id":46075183333643,"sku":"S3919","price":1.49,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/S3919_1_a50df605-0128-483b-9409-ade46244d151.jpg?v=1730317741","url":"https:\/\/niori.co.uk\/products\/panasonic-aaa-lr03-zinc-carbon-batteries-4-pack","provider":"Niori","version":"1.0","type":"link"}
