Lead-acid batteries are used to start the design of automotive engines and are not deeply discharged . They have a large number of thin plates designed for maximum surface area and, therefore, maximum output current , but it can be easily destroyed by deep discharge . Repeated deep discharge capacity loss will ultimately lead to premature failure due to mechanical stress electrode disintegration generation cycle. Starting the battery maintains a continuous floating charge that will corrode the electrode, which will lead to premature failure . The starting battery should be kept open and controlled to prevent vulcanization on a regular basis ( at least every 2 weeks) . Lighter weight than the starting cell batteries deep cycle batteries, since the panels do not extend to the bottom of the battery case. This allows the stripper plate and the disintegration of the loose cells were collected, extend battery life. If the loose fragments, can be raised to a touch panel, resulting in a failure of the cell, causing the cell voltage and capacity loss. Article from http://
Material characteristic: Using high quality aluminum extruded shutter profiles, multi-layer painting or film layer surface have excellent scratch resistance function, not decay, wearable and anti-collision.Nice white profiles, accepting mass customization according to users requirements(light gray, brown, cream, wood, fused, sand color and light sand color ,etc.)
