Lithium battery capacity tester module Xh-m239 18650 (measured in mAh/mWh)

Features: Wide range of applications, compact size. Simple and intuitive to use. Intelligent chip control, clear LCD screen, precise measurement. The minimum discharge voltage of an 18650 battery is 2.75V. Generally, when the voltage reaches 0.875 times the nominal voltage (3.24V), it is advisable to recharge it. Prolonged use will result in a rapid voltage drop and a risk of damage from over-discharge, thus reducing its lifespan. (Recommended discharge voltage: 3.5V). The charging voltage is typically between 4.20V and 4.3V.
