No, 18650 is a manufacturing standard for batteries, which refers to a cylindrical battery with a diameter of 18mm and a length of 65mm. The internal storage material may be a lithium polymer or a nickel metal hydride polymer. improving the production process of lithium batteries, the storage medium of most 18650 batteries is lithium polymer.
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 of 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 security performance ofs batteries are 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.
