Zhang welcome You can inquire trading volume shipped directly from the manufacturer price advantage is obvious where the company sells products for professional and technical personnel to guide access to services, the national free shipping, lowest price, best service, factory warranty 3 years 10 hour rate discharge The nominal capacity of the battery is discharging the battery 5 ℃ ~ 35 ℃, the discharge to 1.8V / single cell, a 10-hour rate of discharge capacity. 20hr corresponding nominal discharge capacity of the battery is discharged under the same conditions for 20 hours. Discharge generally have two purposes, first test the battery capacity, the second is to the battery as active. Battery capacity test is generally charged, according to the nominal parameters of discharge, to test whether the battery is full capacity. Test the battery capacity, we found the battery capacity is insufficient, or discovered during charging electric charge does not go, because the plate caused by vulcanization, you need to activate the plates through to restore battery capacity. A long time use is not maintained and do not charge the battery when activated, due to plate curing, a small current plate can not be activated, the need to deeply discharged, the battery voltage and the charging voltage to increase the voltage difference, and then large current shock to activate the plates, which do not need to press the nominal discharge deep discharge, the available high-current discharge short, be careful not to over-discharge. Activation can be done to the battery mentioned above repeated charging and discharging of the way. 5, resistance, self-discharge batteries have internal resistance (in units of mΩ), refers to the internal battery when the current through the resistance, he includes ohmic resistance and polarization resistance, polarization resistance also includes electrochemical polarization resistance and concentration polarization resistance and so on. Since the presence of resistance, the power storage voltage is always less than his open circuit voltage of the power storage his or force. Ohmic resistance is determined by the battery components (such as the gate plate, the active material, separator and the electrolyte, etc.) generated, although follow Ohm's law, but with the charge state of the battery is changed. The polarization resistance is increased with the current density increases, but the relationship is not linear. The size of the internal resistance of the battery is a measure of the quality of a very important parameter, which due to the battery plates, electrolyte materials and processes differ, fewer impurities within the material, process the better, the smaller the internal resistance. The smaller internal resistance, the self-discharge current is smaller, the greater the capacity of the battery, because the material and the impurities in the reaction plates of the active substance, the active substance reducing the plates, thus affecting the battery capacity. Good quality batteries and the poor quality of the internal resistance of the battery varies greatly. Good quality battery has been able to continue large current discharge, because of its resistance is very small, and the poor quality of the battery is not.
