GS Yuasa's advanced battery technologies: empowering modern vehicles for a greener future

Introduction to advanced battery technologies 

AGM and EFB batteries: a leap forward 

GS and Yuasa Absorbent Glass Mat (AGM) and Enhanced Flooded Battery (EFB) types are designed to meet the high demands of modern vehicles. These batteries are essential for vehicles equipped with Start - Stop systems, offering significantly higher start cycles and durability. 

It's vital to replace your vehicle's battery with the same technology (AGM or EFB) originally installed to maintain emission control systems' functionality and avoid premature battery failure. Incorrect battery replacement can lead to loss of Start - Stop functionality, causing a risk in CO2 emissions, and reduced fuel economy. 

Many vehicles fitted with an AGM or EFB battery will require battery validation using an OBD configuration tool after a replacement. See below for more details. 

Battery validation 

As vehicle technology advances, battery validation has become an essential part of the replacement process. Systems such as Start-Stop, charge management, and regenerative braking place increased demands on the battery, meaning that vehicles require the correct technology – typically AGM or EFB – to operate effectively.

Most modern vehicles are also fitted with a Battery Management System (BMS). When replacing the battery, this system must be reset to recognise the new unit. If not correctly validated, the vehicle may suffer from premature battery failure or a complete loss of key functions such as Start-Stop, regenerative braking, or even energy-saving charge management.

To make this process simple and reliable, GS Yuasa developed the Yu-Fit+ configuration tool. In as little as 60 seconds, workshops can carry out battery validation and reset the BMS, ensuring all advanced vehicle systems continue to perform as intended. The Yu-Fit+ is also capable of working with the latest secure vehicle systems, including Vehicle Secure Access (VSA) and Schutz Fahrzeug Diagnose (SFD), giving technicians a quick and future-proof solution.

Maintenance & charging 

Both EFB and AGM battery types are designed to be maintenance free, although, as with all batteries periodic charging may be required during times of storage or reduced usage. For AGM batteries it is crucial to use a smart charger compatible with AGM technology to prevent damage and maintain battery health. EFB types can usually be charged on a smart charger’s ‘wet’ battery setting. 

Hybrid & electric vehicle battery solutions 

GS Yuasa's portfolio extends beyond AGM and EFB to include advanced battery solutions for hybrid and electric vehicles (EVs), employing state-of-the-art lithium-ion technology. These batteries are designed for the high voltage and energy requirements of EVs, offering longevity and efficiency critical for sustainable transportation.
