To charge the battery, you must be careful before you can use it. Batteries differ depending on their chemical components and therefore require different care.
Charging 18650 lithium-ion battery
Such batteries have many advantages over other types of batteries, as they have no memory effect and have a greater capacity to store energy. To find more about the 18650 lithium ion battery visit https://ibatteries.net/collections/18650.

An important aspect is that there are no high-speed chargers for this type of battery or chargers that will extend the life of these batteries. Charging a 18650 lithium-ion battery to high voltage may cause the battery to overheat and explode or catch fire. In order to prevent the occurrence of such accidents, the battery is built with a safety circuit.
For this reason, if you need lithium-ion batteries, you should always choose a 18650 lithium-ion battery. A battery purchased for a low price may seem like good business, but it poses a security risk by not including this scheme, which prevents the battery from charging while it is charging.
One thing you need to do to extend battery life is not to let it get fully charged. It takes longer to make a small charger than it does to fully discharge. However, a full charge and discharge cycle may be required to calibrate the battery. This calibration should be done as needed and not routinely.
