When selecting an battery for your device or project, the brand and manufacturer play a crucial role in ensuring performance, reliability, and safety. Not all battery brands uphold the same standards, and unfortunately, some exaggerate their specifications to appear superior, which can be misleading and even dangerous.

Trusted Manufacturers

There are five major battery manufacturers known for their quality, consistency, and accurate ratings:

' LG Chem
' Molicel
' Samsung SDI
' Sony | Murata
' Panasonic | Sanyo

These brands have long-standing reputations for producing high-quality lithium-ion cells with documented and verified specifications. In fact, their batteries often outperform the manufacturer's published ratings due to rigorous testing and superior manufacturing standards.

Rewrapped & Aftermarket Brands

Brands such as Efest, Vapcell, Imren, and MXJO do not manufacture their own lithium-ion cells but instead re-wrap and repackage cells from other manufacturers. While their quality has improved over time, they often inflate performance ratings to attract buyers. However, they do add value by:

• Using thicker PVC wraps for additional protection.
• Including carrying cases for added convenience.

Beware of Exaggerated Ratings

There are many unknown or generic brands that overstate their battery specs, sometimes claiming capacities and discharge rates that simply do not exist. As of , no authentic lithium-ion battery exceeds:

' mAh capacity
' 40A Continuous Discharge Rating (CDR)

If you see batteries advertised above these limits, you should be extremely cautious, as these claims are false and misleading.

Reliable Testing Resources

For verified battery performance data, independent testers such as Battery Mooch conduct thorough evaluations and help consumers identify safe and accurately rated batteries. Staying informed with trusted sources ensures you make the best choice for your power needs.

By choosing a reputable brand, you ensure safety, longevity, and optimal performance for your device.

While battery chemistry isn't a primary concern for most consumers when choosing an battery, it plays a role in safety and performance. The key factors to consider when selecting a battery include Brand, Capacity, Discharge Rating, Voltage, and Operating Temperature.

However, some lithium-ion chemistries are more volatile than others. Below is a ranking from least volatile to most volatile:

Proper care and handling of lithium-ion batteries can extend their lifespan and ensure safety. Below are key recommendations to help you get the most out of your batteries.

Key Battery Care Tips

' Temperature Management

• Lithium-ion batteries degrade faster when exposed to extreme temperatures.
• Operating below 0°C (32°F) or above 45°C (113°F) will shorten battery life.
• If your battery is running hot, it's being pushed too hard and may age prematurely.

' Browse our High-Temperature Batteries for better performance in demanding conditions.

' Discharging & Charging Best Practices

• For maximum battery lifespan, keep the voltage between 3.0V ' 4.0V whenever possible.
• Most batteries can discharge as low as 2.5V and charge up to 4.2V, but pushing them to these extremes reduces longevity.
• Batteries maintained within the 3.0V ' 4.0V range can have double the lifespan compared to those frequently pushed to max/min voltages.

' Choosing the Right Charger

• Use a smart charger that automatically turns off when charging is complete.
• Avoid leaving batteries in the charger after they are fully charged. Some chargers continuously top off the battery, which puts unnecessary stress on the cells and accelerates aging.

' We recommend using a Smart Charger that safely maintains your battery's health.

' Charge Rate Considerations

• Some chargers can charge at 4A or 6A, but rapid charging puts added stress on battery cells.
• For a longer-lasting battery, charge between 0.1A and 3A.
• Slower charging preserves capacity and ensures stable long-term performance.
