Lead-Acid Batteries

Introduction
The Yuasa Elite range has been designed to offer the consumer a battery that combines the latest technological advancements in battery design with maximum performance and durability. Elite batteries exceed most OEM battery safety and performance standards. The Elite range consists of 6 references covering approximately 80% of the UK vehicle parc.

Features
Ultimate Performance
The new Elite battery features the most advanced battery technology available on the market today. It contains additional premium active material, providing superior performance and greatly increased service life compared to conventional batteries.

Leakage Protection
The new Elite lid design meets and exceeds the latest German OEM safety standards for acid leakage under extreme conditions. These standards require that the battery can withstand acid leakage when upside down for a minimum of 30 minutes when ‘off charge’ and a minimum of 2 minutes whilst receiving a charge. Many of the newer vehicles on our roads have the battery fitted inside the passenger compartment, usually under the rear seat or in the boot. In the event of an accident whereby the vehicle has rolled onto its side or roof, conventional batteries will immediately begin leaking acid into the passenger compartment. This can be extremely hazardous to the occupant of the vehicle. The new Elite range prevents the leakage of acid in these situations.

Maintenance Free
All Elite batteries conform to the relevant section of EN50342:2006 for maintenance free characteristics (VLWL – very low water loss). This means that when used in approved vehicle applications that operate in normal conditions, it is not necessary to add water to the battery.
Elite batteries are maintenance possible not impossible, the batteries are designed to be topped up if water loss has occurred. Excess water loss can be caused by many things, amongst the most common are a charging system fault, prolonged operation in hot climates and excessive off vehicle charging.

Deep Cycle
Modern cars have an array of electrical devices fitted as standard with many more being available in the aftermarket. This has meant that batteries are working harder than ever and consequently the service life is reduced.
The new Elite range has been designed using special plate materials and processes which enable the battery to be deep discharged and recharged (cycled) without affecting the starting performance. The Elite battery can typically cycle 25% more than a conventional battery.

Charge Indicator
A charge indicator gives an indication at a glance of the battery's state of charge. It provides information on the energy available from your battery and can potentially avoid a vehicle starting problem in the near future.
Green: Battery is charged (typically 60% plus). It should provide a reliable vehicle start.
Black: The battery's state of charge is not in its optimum state. The battery should be recharged. If the vehicle has not been left standing for a while, check for any current drain from recently fitted devices or interior lamps.
Clear: Check electrolyte level and refill with distilled water. Check for a possible alternator regulator fault which would cause high water loss.

Safety Venting
All the Elite batteries feature a Flame Arrestor disc built into the lid. This provides complete protection from external sparks.
The new Elite batteries are all end venting. This allows the gases that are produced during charging to be piped to the atmosphere as specified and required by many vehicle manufacturers.

Ultimate Expanded Calcium Technology
Ultimate expanded positive grid plate technology utilises specially rolled (wrought) Lead/Calcium/Tin (SCS) alloys and developed plate manufacturing process to give the optimum automotive battery design.
The wrought expanded grid process gives a significantly stronger and smaller grid grain structure than comparable cast calcium-silver alloys. Yuasa’s innovative plate manufacturing and formation processes are essential in maximising the benefits of Expanded Calcium technology.
