Both Ni-MH and Li-ion batteries are common rechargeable batteries, and Li-ion batteries have a wider range of applications. The most prominent advantage of Li-ion batteries is their higher energy density. In the same volume, Li-ion batteries can usually store more than 2 to 3 times the amount of electricity that Ni-MH batteries can store. Li-ion batteries have a much lower self-discharge rate than Ni-MH batteries. This means that after being placed for a few months, the remaining power in Li-ion batteries is much more than that in NiMH batteries. In addition, Li-ion batteries also have better performance in charge and discharge efficiency and cycle life.
The advantage of Ni-MH batteries is that they are safer and have a low risk of explosion or fire. They are easier to recycle and are very environmentally friendly at a lower cost. In addition, Ni-MH batteries have better temperature adaptability, especially in low temperature (below 0℃) environments, they can release more power. They are more suitable for working in complex outdoor environments.
No matter what type of battery, VTCBATT will do its best to ensure their quality and safety. You can buy flashlight batteries here with confidence.
Protection circuits are mainly used in Li-ion batteries. It is essentially a miniaturized battery protection board. Their role is similar to the core protection function of the BMS in large battery packs, but with a simplified design for single-cell batteries. We provide customized services for this. You are free to choose whether your flashlight battery has protection circuits.
If you want to choose the right battery for a flashlight for daily use or outdoor emergency, we recommend that you choose a flashlight battery with protection circuits. Because this can prevent overload damage to the battery, eliminate the risk of short circuit explosion, and protect your electronic components. It is your best choice to save costs and protect your own safety.
However, if you are a flashlight enthusiast and want to pursue the ultimate lighting effect (over 10,000 lumens). Then batteries without protection circuits are a better choice. Because the internal resistance of flashlight batteries with protection current is large and the discharge current is limited. This will affect the lighting effect of your ultra-bright flashlight.
VTCBATT flashlight batteries are extremely safe and can withstand continuous charging for a month. They also have excellent resistance to overcharge and over-discharge. Even so, for the life of the flashlight battery, please maintain correct charging habits, such as knowing the correct charging time, avoiding overcharging, and using matching chargers and batteries.
If you don’t use the flashlight for a long time, it’s best to remove the battery. Keep it at 50% discharged. To extend the life of the flashlight battery, store it in a cool and dry environment. Most importantly, keep it away from heat sources and avoid direct sunlight. This helps reduce the self-discharge of the battery. Our flashlight battery has a self-discharge rate as low as 5%. As long as it is stored properly, it can maintain its charge for a long time and work in an emergency.
