Varta C Alkaline (LR14) Batteries

Varta C Alkaline batteries are 1.5 V primary cells designed for steady, dependable power in medium‑drain devices such as portable radios, camping lanterns, children’s toys, and small speakers/boomboxes that accept C cells.

Quick specs

Size / Standard	C (IEC: LR14; ANSI: 14A; also known as MN1400)
Chemistry	Alkaline (Zn/MnO₂), non‑rechargeable
Nominal voltage	1.5 V per cell
Dimensions	Approx. 50 mm (L) × 26 mm (Ø)
Shelf life	Long storage life when kept cool and dry (commonly 5+ years)
Leak resistance	Designed with leak‑resistant construction to help protect devices

When to choose Varta C Alkaline

• Use if: You need ready‑to‑use power for medium‑drain devices used occasionally (radios, LED lanterns, toys, clocks).
• Avoid if: Your device draws high current for long periods (power tools, high‑output lighting) or you use it daily—NiMH C rechargeables are usually more cost‑effective and eco‑friendly over time.
• Cold weather use: Alkaline performance drops in freezing temperatures; for sustained use below 32°F (0°C), consider quality NiMH cells and keep spares warm.

Device fit and compatibility

• Compatible with devices that specify C, LR14, 14A, or MN1400.
• Do not mix with different chemistries (e.g., zinc‑carbon, NiMH) or with cells of different ages/brands in the same device.
• Install all cells in a device at the same time and match polarity (+/−) as marked.

Typical runtimes (ballpark)

Actual runtime varies by device, brightness/volume settings, and temperature. These examples assume steady use:

• Portable radio (60–100 mA): roughly 2–4 days of continuous play per set of cells.
• LED lantern (200–300 mA): about 10–20 hours on medium brightness.
• Toy with motors (400–600 mA bursts): several play sessions totaling 4–10 hours.

Tip: Lower brightness/volume can extend runtime substantially.

Storage and care

• Store unopened cells in a cool, dry place (around 50–77°F / 10–25°C); avoid heat and humidity.
• Remove batteries from devices you won’t use for a month or longer.
• Do not attempt to recharge, short‑circuit, or disassemble.
• If a cell leaks, wear gloves, ventilate, and dispose of all affected cells; clean the device battery compartment per the manufacturer’s guidance.

Alternatives

• NiMH C rechargeables (1.2 V): Best for frequent use; stable performance under higher loads and lower long‑term cost. Ensure your device works with 1.2 V cells.
• Zinc‑carbon R14: Lower cost but shorter runtime; not recommended for modern electronics.

FAQ

Can I use C alkaline and C rechargeable cells together?

No. Mixing chemistries or mixing old and new cells reduces performance and increases leak risk.

Why does my lantern’s runtime vary so much?

Higher brightness draws more current, which shortens runtime; cold temperatures also reduce alkaline output. Use a lower mode and keep spares warm.

Are these safe for air travel?

Yes. Primary alkaline cells are allowed in carry‑on and checked baggage. Keep them in original packaging or cover terminals to prevent short circuits.

How should I dispose of used alkaline batteries?

Follow local guidelines. Many areas allow household disposal; others offer battery recycling drop‑offs. Never incinerate.
