Distributed by Doubglas and Sons (DSL), the YUASA Valve Regulated Lead-Acid (VRLA) battery is ideal for hybrid vehicles. Manufactured in Japan, the Original Equipment Manufacturer (OEM) is installed at the Toyota Factory. While the vehicle is powered through the main battery, the YUASA Auxiliary battery control the electronic grid, data base storage and parking backup. The battery releases the gases emitted while the vehicle is in operation to the outside through a protective exhaust valve. Therefore, the passengers are protected from toxic gas emission. YUASA is the only battery to offer such safety standards to the vehicle-owner. Through the system, the Auxiliary VRLA also safeguards the air condition system and the electronic grid from the effects of toxic gas. Having been in operations since 1986, DSL has diversified into several sectors including importing, sales & distribution, and soft toys. With three warehouse complexes, the company is able to cater uninterrupted supply to the consumers.
