When you look for reliable, cost‑effective primary batteries for household gadgets, the R14P C‑size (UM‑2) carbon‑zinc battery is one of the most widely used options around the world. Also known as the “C battery”, this 1.5V super heavy‑duty cell powers many everyday devices from torches, radios, toys to portable kitchen appliances.
What Is R14P?
Model: R14P
Size: C / UM‑2
Nominal Voltage: 1.5 V
Chemistry: Carbon‑Zinc (Super Heavy Duty)
Marking: 0% mercury & cadmium, eco‑friendly formulation.
The letter R means round cylindrical cell; 14 stands for C‑size dimension. The suffix P represents “power type”, for improved discharge performance compared to standard R14 carbon batteries. These are non‑rechargeable disposable batteries manufactured for global markets.
Typical Applications
R14P carbon‑zinc batteries excel in low‑to‑moderate drain equipment:
✅ Portable flashlights & lanterns
✅ Table radios, boom‑boxes
✅ Large‑size children’s toys
✅ Gas detectors, smoke alarms
✅ Clocks and portable measuring instruments
They are not designed for high‑current continuous devices; carbon‑zinc technology delivers stable runtime for intermittent use, making it an economical choice for home and industrial bulk purchasing.
Key Features of Naccon R14P
Zero Mercury & Cadmium: Environment‑friendly, meets global consumer battery requirements.
Stable 1.5 V output: Consistent voltage output during most of service life.
Robust anti‑leak construction: Well‑built shell reduces risk of electrolyte leakage even after full discharge.
Important Safety Warnings Printed on Cell
As labelled on every battery jacket:
Do not recharge, short‑circuit, disassemble or throw into fire. Wrong installation can cause heating, leakage or explosion. Always check positive (+) and negative (−) polarity before fitting batteries into devices.
Keep away from children. Do not mix old and new batteries or different battery chemistries in one device.
Difference between carbon‑zinc R14P vs alkaline C‑size
Many buyers confuse R14P carbon battery with LR14 alkaline C battery:
Item | R14P Carbon‑Zinc | LR14 Alkaline |
|---|---|---|
Cost | Lower price point | Higher cost |
Drain suitability | Low‑medium drain | High‑drain devices |
Battery life | Good for intermittent use | Much longer runtime |
Shelf life | 2 years | 5‑10 years |
For cost‑sensitive bulk projects, R14P super heavy‑duty carbon zinc offers great value, especially for devices that are not running non‑stop. If your equipment draws heavy continuous current, alkaline LR14 will perform better.
Storage & Handling Tips
Store in cool, dry room temperature environment; avoid direct sunlight or high‑temperature cabinets.
Do not leave exhausted batteries inside equipment for long periods to prevent leakage damage.
Bulk carton packing keeps large‑volume orders well protected during ocean or air shipment.
Closing Summary
R14P UM‑2 C‑size carbon‑zinc battery remains a workhorse disposable cell in today’s market. It delivers dependable 1.5V power at competitive cost for countless household and commercial devices. When selecting primary C‑size batteries, confirm the model is R14P Super Heavy Duty if carbon‑zinc performance fits your project requirements.
