12V280ah Marine Battery Dry Charged Boat Battery Low Maintenance Free Battery

Improvements:

1, RADIATION OR GRIDDING PLATES: Adopting advanced plate casters to produce much thicker plates with Pb-Ca-Sn alloy. This can ensure complete maintenance-free performance of minimum self-discharge. Furthermore, uniformity of our plates are greatly improved with our special solidification technology, which can reduce possibility in sulfation and keep much stronger cranking performance.
2, SEPARATOR: The super-thin glass fiber in separator (ir PE envelope) avoids short-circuit of plate group, and reduce electric resistance and increase current capacity. The surface fiber can protect effectively the active material of positive plates from dropping off in vibration. And then it can extend battery life.
3, POLES: The poles are made by mechanical operation, which can ensure no leakage. It makes sure the poles more durable than the traditional ones as we adopt special technical process.
4, CENTRAL BUSBAR: With the most advanced COS machine, we can connect plate groups very well in each cell, which is called busbar. And the busbar has some good features such as low internal resistance, high good electric conductivity and high resistance to vibration.
5, MAGIC-EYE: Magic eye is also called as indicator, which can tell the state of a battery.
6, FRAME ARRESTER: Prevent explosion caused by gas or spark while charging. And it can also stop any free acid from inside.
7, PP CONTAINER: Our battery has excellent performance of non-leakage and anti-explosion with very special structure in container.
8, HEAT SEALED COVER: Heat sealed design is to maximize strength and rigidity to prevent electrolyte leakage.
