The Lucas Supreme series is a premium line of automotive batteries designed to deliver top-tier performance, durability, and reliability for drivers who demand more from their vehicles. Built using high-quality materials and advanced lead-acid technology, the Supreme range is ideal for cars with greater electrical demands but without start-stop systems. This series caters to motorists who want dependable cold-cranking performance, longer service life, and consistent voltage stability across a wide range of driving conditions. Known for its robust internal construction and maintenance-free operation, Lucas Supreme batteries are a smart choice for ensuring your vehicle’s electronics and engine start-up systems operate flawlessly, even in challenging climates.

The Lucas LS027 is a standout model in the Supreme range, offering an impressive 65 Ah capacity and a cold cranking current of 640 A. This makes it particularly suitable for mid-sized petrol and diesel vehicles that require strong starting power along with the ability to support auxiliary systems such as infotainment, lighting, heating, and power windows. The LS027 is well-suited to drivers who regularly take longer journeys or operate in colder environments where higher starting power is essential.

In terms of size, the LS027 measures 242 mm in length, 175 mm in width, and 190 mm in height. These dimensions correspond precisely with the L2 group size, a widely used European standard for compact to mid-size passenger vehicles. The battery’s proportions make it compatible with a broad range of European models, offering an excellent fit without modifications. It also features a B13 mounting base, which includes a bottom ledge running around the perimeter—this ensures secure installation and minimizes the risk of battery movement during driving. The LS027 uses terminal layout 0 (positive terminal on the right) and standard terminal type 1, making it easy to install as a direct replacement for many OEM batteries.

The LS027 is designed for vehicles without start-stop systems. While it does not use EFB or AGM technology, it excels in traditional 12V applications by delivering reliable and consistent performance. Its strong 640 A cranking power outperforms many competitors in the same size class. For example, while models like the Bosch S4 S40 05 and Varta Blue Dynamic D24 offer similar dimensions and a capacity of 60 Ah with 540 A cranking power, the LS027 delivers greater starting strength. It also matches premium models like the Bosch S5 S50 05 (63 Ah / 610 A) and the Varta Silver Dynamic D15 (63 Ah / 610 A), proving itself a worthy option in the high-performance category.

Furthermore, the LS027’s robust internal design enhances resistance to vibration and extends service life under standard driving conditions. It is completely maintenance-free, meaning there’s no need to check water levels, and it’s built to hold its charge effectively during periods of infrequent use—ideal for vehicles that may not be driven daily.

To sum up, the Lucas Supreme LS027 is a reliable, high-performance battery tailored for conventional 12V vehicle systems. With its strong 65 Ah capacity, powerful 640 A cold start rating, and compatibility with L2-sized battery compartments, it’s an excellent upgrade or replacement for drivers seeking dependable, long-lasting performance in both urban and long-distance driving scenarios.
