Technical Features

Long Design Life

The expected design life is fifteen years in float standby applications at 25°C

Sealed Construction

Yuasa’s unique construction and sealing technique ensures no electrolyte leakage from case or terminals.

Electrolyte Suspension System

All UXL batteries utilise Yuasa’s unique electrolyte suspension system, retaining the electrolytes in the separator material.

Valve Regulated Design

The batteries are equipped with a low pressure venting system which releases excess gas and automatically reseals in the event of gas build up in the battery. Note that on no account should the battery be charged in a sealed container. The design of Yuasa’s UXL batteries incorporates oxygen recombination reactions to eliminate the need to replenish with water.

Low Maintenance Operation

Due to the Yuasa’s sealed construction and the recombination of gases within the cell, the battery is almost maintenance free.

Operation in any Orientation

The combination of sealed construction and Yuasa’s unique electrolyte suspension system allows operation in any orientation, with no loss of performance or concern of electrolyte leakage (Excluding continuous use in an inverted position).

Separators

The separators used are made from a microfibre glass mat material which provide physical insulation between the plates, thus preventing inter-plate short circuits and significantly reducing the shedding of the active material.

Recyclable Materials used in Battery

All Yuasa lead acid batteries can be recycled.
