What is the maximum discharge current of the lead battery?

The provisions of the battery discharge conditions are as follow:

⑴The improvement of the discharge current of the battery generally is the discharge rate.

⑵Discharging termination voltage, discharge current, termination of the discharge voltage is not the same

(3) Discharge temperature, low temperature when the battery discharge capacity is small, high temperature when the discharge capacity is big, in order to uniform provisions of the discharge temperature discharge capacity.

Discharge rate is according to the size of the battery discharge current, time ratio and current ratio respectively.

Discharge rate refers to the time under the condition of a certain discharge, discharge to the termination voltage the length of time. According to IEC standard, the rate of discharge rate respectively for 20 hours (20 Hr, one of the most general, general is the battery on) rate (Hr) 10, 10 hours, 5 hours rate (Hr) 5, 3 hour rate (Hr), 2 hour rate (Hr), 1 hour rate (1 Hr), 0.5 hour rate (0.5 Hr) and so on.

The battery discharge current is different, can release the capacity is not the same, the larger the discharge current, can let out the smaller power.

In addition, the larger discharge current is, the shorter battery life is. The deeper the depth of discharge, battery life is short.

Lead-acid battery can cope with large current discharge for a short period of time, and then discharge depth is not deep. Small current discharge, even slightly deep discharge depth, little effect on battery life. The most afraid is that continuous large current discharge and the depth of discharge.

3 a maximum charging current

As the battery discharge, the positive and negative plates are sulfide, at the same time, the sulfuric acid electrolyte to reduce gradually, and more water, thus resulting in a decline in the proportion of the electrolyte in actual use, can be determine by measuring the proportion of the electrolyte of battery discharge. Under normal use, should not be lead battery discharge excessive, otherwise will lead to small and active material to mix together lead sulfate crystals formed a larger body, which not only increased the resistance of the plate, and it is hard to make it to restore when charging, a direct impact on the capacity and life of the storage pool. Lead battery discharge is the inverse process.

Lead-acid battery charge and discharge the principle of chemical reaction equations are as follows:

The positive: PbO2 + 2 e + SO42 - + 4 h + = = PbSO4 + 2 h2o

Negative: Pb - 2 e + SO42 - = = PbSO4

Cathode: PbSO4 + 2 e - = Pb + SO42 -;

Anode: PbSO4 + 2 h2o - e - 2 = PbO2 + 4 h + + SO42 -.

Total reaction: PbO2 + 2 - h2so4 pbso4 + Pb = = 2 + 2 h2o (positive discharge, reverse charge)

(Lead battery discharge is the quality of anode increases, reason: lead battery discharge, the anode plate with PbSO4 attached quality increase: has PbSO4 anode plate, so the quality is also increased.)

Lead-acid electric overall is divided into three categories;1 start-up battery 2 power battery 3 UPS battery. The maximum discharge current of start-up battery in short time is five times as its total capacity. This is what CCA (marked on the battery) means. If your 10 Ah battery of motorcycle battery can be released more than 50 Ann current of two kinds of battery above, their discharge current will be smaller. One tenth of the charging current for the capacity is 1Ah.
