AGM Technology for Advanced Start-Stop Vehicles

AGM Car Battery Technology for Advanced Start-Stop Systems
THE MAX POWER FOR MAX PERFORMANCE

High-performance, highly equipped vehicles lay massive demands on their battery nowadays, and the continuous investments in R&D have allowed Western Electrical to introduce the latest innovative AGM batteries to the aftermarket.

Featuring superb starting and deep-cycle ability, the Western Electrical AGM Supreme automotive battery series is the perfect solution for vehicles with advanced Start-Stop technology, regenerative braking and additional hybrid fuel-saving systems. Only specially developed automotive batteries with AGM technology can meet the challenges imposed by these systems - offering even greater performance and versatility, and reliably supplying power to an even greater range of devices.

Key Components Inside

01

Sealed Double Security Lid

Sealed double security lid with degassing outlet and flame arrester of AGM car battery
The sealed double security lid with a degassing outlet and flame arrester safely vents excess gas and blocks external ignition sources, protecting both the battery and the engine compartment.
02

Tall Plate Group

Tall plate group installed under high compression inside AGM automotive battery
The tall plate group installed under high compression withstands vibration and prevents active mass shedding, maintaining stable capacity through frequent start-stop cycling.
03

Framed Negative Plate

Framed negative plate of AGM automotive battery
The framed negative plate reinforces the plate edges against growth and distortion, preserving grid alignment and stable capacity throughout deep-cycle service.
04

Framed Positive Plate

Framed positive plate with high-tech alloy grid of AGM automotive battery
New framed grid design with a high-tech alloy resists corrosion and grid growth; the surrounding high-capillarity glass mat provides extra absorption for maximum electrolyte volume and prevents acid stratification.
05

Absorbent Glass Mat Separator

Absorbent glass mat separator holding the electrolyte inside AGM car battery
The absorbent glass mat separator holds the electrolyte in its glass fleece pores, eliminating free acid inside the battery - the foundation of spill-proof operation and internal oxygen recombination.
06

Thicker Polypropylene Case

Thicker polypropylene case of AGM automotive battery
The thicker polypropylene case adds mechanical strength and vibration resistance, shielding the high-compression plate group over demanding start-stop operation.

The Start Stop System and the Role of a Start Stop Battery

Start stop system working cycle - starting, driving, engine stop and restarting phases with battery charge and discharge waveform

The Start Stop System automatically stops the engine when the vehicle is not moving and restarts it as soon as the vehicle begins to accelerate. This technology avoids unnecessary energy loss caused by engine idling and has been proven to cut fuel consumption by 5-15%, while improving engine silence for greater driving comfort.

Start-Stop vehicles require an enhanced battery due to the frequent start and stop events at traffic lights. A battery with enhanced durability and charge acceptance is needed to withstand these severe driving environments - which is exactly what the AGM Supreme design delivers, cycle after cycle.

Key Advantages

  • Designed for vehicles with advanced Start-Stop systems and high electrical loads
  • Up to three times the cycle life of conventional flooded batteries
  • Matching original spare parts specifications
  • Environmentally friendly - lower fuel consumption and reduced CO2 emissions
Please note: traditional lead-acid batteries are not suitable for Start-Stop micro-hybrid vehicles. When replacing the battery, Western Electrical recommends installing an EFB or AGM battery of the same group size, respecting the original battery technology - and an AGM battery should always be replaced with a new AGM battery.

AGM technology sits at the top of the lead-acid range - delivering maximum starting power, superior deep-cycle durability and full support for regenerative braking in the most demanding vehicles. AGM SUPREME automotive batteries from Western Electrical are engineered for advanced Start-Stop vehicles.
