Relatively speaking, it is the most secure.
1. The technical specifications are unified and the maturity level is the highest.
2. Round shape, balanced pressure resistance, unlike square or soft bags with a bulge in the middle.
3*, with a safety valve design, can cut off the positive and negative poles of the battery core when the internal pressure is too high or short circuited, and release the pressure to ensure the security
p>3 is the power supply type. One of the basic configurations of 18650 battery cells, which may not be available in non-powered models.
1. Batteries have different capacities. The capacity of 18650 batteries is generally between 1200 mAh and 3600 mAh, while the capacity of ordinary lithium batteries of the same volume is around 800 mAh; >
2. Battery life is different. The lifespan ofe 18650 battery can reach more than 500 times under normal use. Generally, the lifespan of lithium battery under normal use is about half. that of the 18650 battery;
3. The safety performance of batteries is different. The 18650 lithium battery has high safety performance, does not explode, is non-toxic and non-polluting. Generally, lithium batteries have the risk of explosion when exposed to high temperatures or improper use, and general lithium batteries Internal substances have a high capacity to pollute the environment;
4. The battery discharge voltage is different. The discharge voltage of 18650 lithium battery is generally 3.6 volts, 3.8 volts and 4.2 volts, the discharge voltage of general lithium batteries is about 3.0 volts.
