An LR14 battery is a standard 1.5V alkaline C battery. It is widely used in flashlights, toys, radios, medical devices, and other portable equipment.

In this guide, you’ll learn its specifications, capacity, common uses, battery equivalents, and how it compares with R14 and HR14 batteries.

Key takeaways

  • LR14 is a 1.5V alkaline C-size battery.
  • A C battery describes the size. LR14 describes the battery type.
  • Typical capacity is 6,000–8,000 mAh, depending on the brand and device.
  • Common LR14 battery equivalents include MN1400, E93, and AM2.
  • LR14 batteries are not rechargeable.
  • HR14 batteries are the rechargeable alternative.

Part 1. What is an lr14 battery?

LR14 battery C-size alkaline 1.5V battery structure and IEC LR14 standard identification

An LR14 battery is a non-rechargeable alkaline C battery. It uses alkaline manganese dioxide chemistry and delivers a nominal voltage of 1.5V.

The name comes from the IEC battery standard:

  • LR = alkaline chemistry
  • 14 = C-size battery

Many people search for LR14 battery, battery LR14, or C/LR14 battery. These names usually refer to the same battery.

Compared with zinc-carbon batteries, LR14 batteries last longer and provide more stable power. They are a good choice for devices that run for many hours.

Main Features

  • IEC code: LR14
  • Battery size: C
  • Voltage: 1.5V
  • Chemistry: Alkaline
  • Rechargeable: No
  • Shelf life: Up to 10 years

Part 2. LR14 battery specifications

The LR14 battery has standard dimensions. Batteries from different brands fit the same C-size battery compartment.

Specification Value
IEC code LR14
Size C
Voltage 1.5V
Chemistry Alkaline
Diameter 26.2 mm
Height 50 mm
Capacity 6,000–8,000 mAh*
Weight 65–75 g
Shelf life Up to 10 years
Operating temperature -18°C to 55°C
Rechargeable No

*Capacity depends on the battery brand, discharge rate, and operating conditions.

Why does capacity change?

Battery capacity is not always the same. Devices that use more power drain the battery faster. For example, a flashlight uses more energy than a wall clock. As a result, the same LR14 battery will last for different lengths of time.

Part 3. Common applications of LR14 batteries

The LR14 battery works well in medium-drain devices. It offers good runtime without making the device too large or heavy.

Common applications include:

Device Why LR14 Is Used
Flashlights Long-lasting power
Portable radios Stable output
Toys Good capacity for motors
Blood pressure monitors Reliable performance
Thermometers Long shelf life
Electric toothbrushes Consistent power
Camping lanterns Suitable for outdoor use
Emergency equipment Ready after long storage

Its long shelf life also makes it a good choice for emergency kits.

Part 4. How long does an LR14 battery last?

Battery life depends on the device and how much power it uses.

Here are typical runtimes.

Device Typical Runtime
Wall clocks 6–18 months
Portable radios 20–60 hours
LED lanterns 15–40 hours
Flashlights 5–20 hours
Battery toys 4–15 hours

You can extend battery life by following a few simple tips:

  • Store batteries in a cool, dry place.
  • Replace all batteries together.
  • Do not mix old and new batteries.
  • Do not mix different battery types.
  • Remove batteries from unused devices.

Part 5. Is an LR14 battery the same as a C battery?

Yes, but not exactly.

A C battery describes the battery size. LR14 describes an alkaline battery in the C-size format.

Here is the difference:

  • C battery = battery size
  • LR14 = alkaline C battery
  • R14 = zinc-carbon C battery
  • HR14 = rechargeable NiMH C battery

So, every LR14 battery is a C battery. However, not every C battery is an LR14 battery.

Common LR14 battery equivalents

Marking Chemistry Compatible
LR14 Alkaline
MN1400 Alkaline
E93 Alkaline
AM2 Alkaline
C Size only Depends on chemistry

Always check the battery chemistry before replacing a C battery. Some devices work better with alkaline batteries than zinc-carbon or rechargeable types.

Part 6. Can an LR14 battery be recharged?

No. An LR14 battery is a primary alkaline battery. It is made for single use only.

Do not try to recharge an LR14 battery. Recharging can cause:

  • Battery leakage
  • Swelling
  • Overheating
  • Rupture
  • Fire risk

If you need a rechargeable C-size battery, choose an HR14 (NiMH) battery instead. It has the same size but a lower nominal voltage of 1.2V. Most everyday devices can use either type, but always check your device manual first.

Part 7. LR14 vs R14 vs HR14 battery comparison

These batteries have the same C-size dimensions, but they use different chemistries and offer different performance.

Feature LR14 R14 HR14
Battery type Alkaline Zinc-carbon NiMH
Rechargeable No No Yes
Nominal voltage 1.5V 1.5V 1.2V
Typical capacity 6,000–8,000 mAh 2,000–3,000 mAh 2,200–4,000 mAh
Shelf life Up to 10 years 2–3 years 2–5 years*
Best for Medium-drain devices Low-drain devices Frequent daily use
Initial cost Medium Low Higher
Cost over time Medium Medium Lowest after many recharge cycles

*When stored correctly.

Which battery should you choose?

Choose LR14 if you want:

  • Long shelf life
  • Reliable power
  • Better performance in flashlights, radios, and toys

Choose R14 if:

  • Your device uses very little power.
  • Low cost is your main concern.

Choose HR14 if:

  • You use the device every day.
  • You want to reduce battery waste.
  • You already own a compatible charger.

Part 8. LR14 battery equivalent and identification

Many batteries have different names but are actually the same size and chemistry.

Common LR14 battery equivalents include:

Marking Type
LR14 IEC alkaline C battery
MN1400 Duracell designation
E93 Energizer designation
AM2 JIS designation
C Standard battery size

Some users also search for IR14 battery, IR14 batteries, or battery IR14. In most cases, these are typing errors for LR14 battery.

Before buying a replacement, check three things:

  1. Battery size (C)
  2. Voltage (1.5V)
  3. Chemistry (alkaline)

Matching all three helps ensure the best performance.

Part 9. LR14 battery safety tips

Using LR14 batteries correctly helps protect both your device and the battery.

Follow these simple tips:

  • Insert the battery in the correct direction.
  • Do not mix old and new batteries.
  • Do not mix alkaline and zinc-carbon batteries.
  • Store batteries in a cool, dry place.
  • Keep batteries away from children.
  • Remove batteries from devices that will not be used for a long time.
  • Recycle used batteries through a local recycling program.

Never dispose of batteries in fire. Heat can cause them to leak or explode.

For more battery safety information, see the International Electrotechnical Commission (IEC) battery standards and your local recycling guidelines.

Part 10. How to choose the best LR14 battery?

Most LR14 batteries have the same size. However, their performance can vary.

When choosing an LR14 battery, consider these factors:

Device type

Premium alkaline batteries work better in high-drain devices such as flashlights and toys. Budget batteries are often suitable for clocks, radios, and other low-drain devices.

Shelf life

If you keep spare batteries at home or in an emergency kit, choose products with a shelf life of up to 10 years.

Leak protection

Good-quality alkaline batteries are less likely to leak during storage.

Brand reputation

Well-known manufacturers usually provide more consistent performance and better quality control.

Cost

The cheapest battery is not always the best value. A longer-lasting battery often costs less over its full service life.

If your application requires rechargeable power or custom battery packs, lithium battery solutions may provide longer cycle life and higher energy density than disposable C batteries.

LR14 battery application & selection guide

Application Power Level Best Battery Choice Reason
Flashlights Medium–High LR14 Stable output and higher capacity
Toys High LR14 Handles peak load better
Portable radios Medium LR14 Consistent voltage
Wall clocks Low R14 / LR14 Low energy demand
