What Is an R03P Battery?
R03P, also known as AAA or UM4 battery, is a widely used cylindrical carbon-zinc primary dry battery following IEC international standards.
R: Cylindrical battery form
03: AAA size specification
P: High-power grade, marked as Super Heavy Duty
It delivers a nominal voltage of 1.5V, with dimensions of 10.5 mm diameter × 44.5 mm height. Compact and lightweight, this tiny power source fits nearly all small portable electronics designed for AAA cells.
NACCON R03P Super Heavy Duty batteries adopt mature carbon-zinc technology. Constructed with manganese dioxide positive electrode, zinc negative electrode and stabilized electrolyte, they offer consistent, flat discharge performance for low-to-medium drain devices. Our formula achieves 0% mercury, complying with global eco-friendly standards including CE, RoHS and SGS.
