Characteristics of Wholesale maintenance free motorcycle use lead acid 12v 7Ah storage battery

Advantage of Chuangxiang motorcycle battery

Plate: Adopt unique formula improving utilization of active material in plate, in adition, high pure lead ingot(#1 lead purity is 99.99%) as raw material, so high cold cranking performance and low self discharge rate.

Seperator: Absorbed glass mat technology, superior ability of absorbing acid contributes to eliminate acid spill.

Terminal: High integrity of terminal sealing avoids acid leak, lead or copper terminal for choose.

Container: Reinforced ABS container great performance-resistance to gasoline and alcohol gasoline. Integrity of ABS container can resist the leak of gas and acid during the process of useage, it is environmental.

Quality control: All material must be strictly inspected before use, each process is strictly implemented by standard operation procedure, each product must be inspected before delivery to assure high quality product to client.

Lead acid battery advantages & disadvantages

Although lead acid batteries are widely used because they have a number of distinct advantages, they also have several major disadvantages. All these need to be considered when deciding upon whether to use this technology or not.

Lead Acid Battery Advantages

1, Mature technology

2, Relatively cheap to manufacture and buy (they provide the lowest cost per unit capacity for rechargeable cells)

3, Large current capability

4, Can be made for a variety of applications

5, Tolerant to abuse

6, Tolerant of overcharging

7, Wide range of sizes and specifications available

8, Many producers worldwide

Lead Acid Battery Disadvantages

1, Fails after a few years use lifespan typically 300 - 500 cycles

2, Cannot always be used in a variety of orientations

3, Corrosive electrolyte (can cause burns to people and corrosion on metalwork)

4, Lead is not environmentally friendly

5, Acid needs disposing of with care

6, Not suitable for fast charging

7, Must be stored in charged state once electrolyte introduced

8, Typical charging efficiency only around 70%

Lead acid battery self discharge

The self discharge characteristic of the lead acid battery is relatively good. At a room temperature of 20°C the self-discharge rate is around 3% per month> In theory a lead acid battery can be stored for up to 12 months without recharge. However at higher temperatures the self discharge is higher. At 30°C the self-discharge increases and a recharge will be needed after 6 months. Letting the battery drop below 60% for some time causes sulphation.

Sulphation is a process which reduces the capacity of lead acid batteries. During normal use, small sulphate crystals form, but these are normal and are not harmful. During prolonged charge deprivation, however, the amorphous lead sulphate converts to a stable crystalline and deposits on the negative plates. This leads to the development of large crystals that reduce the active material within the cell and result in a reduction of capacity within the cell.
