1.5V lithium batteries, commonly lithium iron (LiFeS2) AA batteries, are increasingly popular for everyday devices such as remote controls, flashlights, cameras, and toys. However, there are many misconceptions about these batteries. This article answers the most common questions to help you use 1.5V lithium batteries safely and effectively.
Misconception 1: 1.5V lithium batteries can be charged anytime
Truth:
l Most 1.5V lithium iron batteries are non-rechargeable. Attempting to charge them can cause leakage or even explosion.
l Rechargeable alternative: If you need rechargeable batteries, choose batteries labeled as NiMH or specifically marked as rechargeable lithium.
l Safety tip: Always check the battery packaging or label before charging.
Misconception 2: 1.5V lithium batteries are the same as alkaline batteries
Truth:
l While the voltage is the same (1.5V), lithium iron batteries perform very differently.
l Higher capacity: Lithium iron batteries can provide approximately three times the capacity of standard alkaline batteries.
l Stable voltage output: Lithium iron batteries maintain nearly constant voltage during use, while alkaline batteries gradually drop.
l Superior low-temperature performance: Lithium iron batteries work reliably in freezing conditions, unlike alkaline batteries.
For high-drain devices or winter outdoor use, lithium iron batteries are much more reliable.
Misconception 3: Long-lasting batteries don’t need careful storage
Truth:
l Although lithium iron batteries have a low self-discharge rate of about 2 to 3 percent per year, proper storage is still important.
l Avoid high heat or humidity
l Keep them in the original packaging or a sealed plastic case
l Check periodically for swelling or leakage
Proper storage ensures stable performance and longer shelf life.
Misconception 4: Lithium batteries are too expensive to be cost-effective
Truth:
l Although the initial cost is higher, long-term use is cheaper.
l Longer life means fewer replacements
l Stable voltage reduces device maintenance
l High reliability results in fewer interruptions in device use
For devices like remote controls, cameras, and flashlights, lithium iron batteries are actually more economical over time.
Misconception 5: Rechargeable lithium batteries are fine for outdoor use
Truth:
l For outdoor activities such as camping, hiking, hunting, skiing, or cycling, disposable lithium iron batteries are generally more reliable than rechargeable NiMH batteries.
l Better low-temperature performance: NiMH batteries (1.2V) lose capacity in cold weather and their lower voltage may be insufficient for some devices, while disposable lithium iron batteries maintain stable 1.5V output even in freezing conditions.
l Convenient storage and backup: Disposable lithium iron batteries hold charge for years without noticeable loss.
l Lightweight and high energy density: Perfect for high-drain devices in outdoor settings.
For outdoor activities, prioritize high-quality 1.5V lithium iron disposable batteries over rechargeable ones.
Misconception 6: Lithium iron batteries are suitable for all devices
Truth:
l Not every device is compatible with lithium iron batteries.
l High-current devices like some power tools may require special high-drain batteries
l Older devices sensitive to voltage may misread lithium iron batteries as low battery
Always check your device manual before replacing batteries.
Misconception 7: Lithium iron batteries are completely safe
Truth:
l Although more stable than other lithium chemistries, safety precautions are still necessary.
l Avoid short circuits and impact
l Do not mix with other metals
l Use trusted brands to ensure consistent quality
Choosing reliable brands like Bevigor guarantees long-lasting, safe, and stable performance.
