How to use The first time a new battery is used, the rated voltage value is close to the actual value, Judgment to stop the discharge voltage. A reasonable discharge voltage value can be obtained according to the general voltage calculation method of the battery. When the old battery is used, the actual voltage value and the rated voltage value are quite different, so you need to measure the stop voltage value in actual use. Battery charging usually uses slow charging (the voltage and current of fast charging are relatively large, and the battery is easily damaged.) The charging voltage of slow charging is 1.2 times the rated voltage, and the charging current is adjusted to about 2/10 of the
