How to use rechargeable flashlight correctly?

The most important thing to use a direct-charging flashlight is to pay attention to the charging time. Although some flashlight chargers have the protection function of preventing overcharging, it is best not to charge them for too long. The charging time of flashlight is only a few hours, so you can estimate the charging time when using it, and keep charging without plugging it in.

Secondly, pay attention to the discharge time. When the brightness of flashlight is obviously reduced, it should be charged. Many batteries are easily damaged by over-discharge. However, many friends often use flashlights to go out without knowing how to charge, which is easy to damage flashlights.

Other aspects are relatively simple, for example, don't put it in the sun, don't put it in a humid place, and avoid being close to heat sources.
