Part 1. What is an lr14 battery?
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:
- Battery size (C)
- Voltage (1.5V)
- 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.
