Battery with different mode of charge and discharge and lifeRecycle discharge and chargeIf the device connected with power supply charge may be moved after saturation then the battery supply equal to power supply power resource.There is limit for highest voltage offered by charger when charge electricity: 2V battery charge voltage: 2.6-2.75V;6V battery charge voltage: 7.2-7.5V; 12V battery charge voltage: 14.4-15.0V. The largest current is not higher (that rated capacity 30% A. For example 6V4AH, The largest current is not higher I=0.3×4A=1.2A )Charge must be stopped when chargers show saturation. Otherwise the battery may be damaged or injured.If according to the Japanese standard-JISC industry, the battery cycling life is up to 250 times.Circulatory charge and discharge (in a circle).Mode of float charge

1.  Of the equipment always been connected power supply and controlled by has been charged, only when external power supply is stopped by battery, In this mode, please choose the float charge mode.

2.  The highest charging voltage of float charge mode machine should be strictly controlled. The float charge voltage at 250C is: 2.26-2.30V/cell, the largest charging current should not be larger than the rating capacity’s 30%A.

3.  The float charge life: the float charge life is more than one year for the battery that the capacity≤24Ah, to the capacity is more than 24Ah, it’s life is more than three years. 

Discharge

The discharge time is more than 20 hours when the voltage is up to 1.8V/cell should be end discharge. The discharge time is between two and twenty hours when the voltage is up to 1.7V/cell should be end discharge; The discharge time is less than tow hours when the voltage is up to 1.6V/cell should be end discharge. Otherwise the battery may be damaged. When discharge is end should be immediately charged.
