In the beginning, charge for 12 hours, and the battery needs to be fully charged for the first 3 times. Rechargeable flashlights are generally lead batteries, which can basically be fully charged in four or five hours. If it is a lithium battery, it is recommended to be fully charged. Don’t let the flashlight recharge at all times, so as not to shorten the life of the flashlight.
Electricity has a great relationship with storage time. You can use it when you buy it. When the brightness of the LED bulb dims, you must charge it in time. The lithium battery should not be overcharged or over-discharged. Some control circuits are better designed and have complete protection measures so that the maintenance requirements for the battery will be much lower.
