Leoch 027AGM Start-Stop Car Battery – 12V 60Ah 660A

The Leoch 027AGM (L2AGM-027) is a high-performance 12V 60Ah AGM start-stop car battery, delivering 660A cold cranking power (CCA) for dependable engine starting in compatible vehicles. Engineered with advanced Absorbent Glass Mat technology, it combines increased cycling durability, rapid charge acceptance and reliable performance under demanding automotive operating conditions.

Built in the L2 battery case size (242 × 175 × 190mm), the 027AGM is designed for vehicles requiring this AGM battery specification, including compatible start-stop applications and vehicles with increased electrical demands.

Key Features & Benefits

• 660A Cold Cranking Power – Strong engine starting performance, including during cold-weather conditions.

• Up to 3× Higher Cycle Life – Greater resistance to repeated discharge and recharge cycles compared with conventional starter batteries.

• Up to 2× Faster Charge Acceptance – Supports efficient energy recovery during frequent engine restarts and charging cycles.

• Advanced AGM Technology – Absorbent Glass Mat construction retains electrolyte within the battery, eliminating free-flowing acid.

• Start-Stop Ready – Engineered for frequent engine restart requirements and increased vehicle electrical loads.

• Partial State-of-Charge Capability – Designed for operation under partial state-of-charge (PSoC) conditions.

• Valve-Regulated Construction – Maintenance-free design with no routine electrolyte topping-up required.

Engineered for Start-Stop Performance

Modern start-stop vehicles place greater demands on their batteries than conventional starting systems. Repeated engine restarts, continued operation of onboard electrical equipment and frequent charging cycles require a battery engineered for sustained cycling performance.

The Leoch 027AGM combines 660A cold cranking performance with the cycling durability and charge acceptance required for these applications.

Its advanced AGM construction supports repeated discharge and recharge cycles, while enhanced charge acceptance enables efficient energy recovery during vehicle operation. This makes the 027AGM suitable for compatible vehicles with demanding start-stop and electrical management systems.

027AGM Replacement Battery – L2 Case Size

The 027AGM is an L2 AGM car battery measuring 242mm long, 175mm wide and 190mm high.

Its L2 case format provides a replacement option for vehicles requiring this battery size and AGM technology, provided the electrical ratings, terminal arrangement and mounting configuration also match.

When replacing an existing 027AGM battery, confirm that the original battery's technology, dimensions, terminal polarity and electrical requirements are compatible.

A battery with matching dimensions is not necessarily interchangeable if its technology, starting performance or terminal configuration differs.

Why Choose an AGM Car Battery?

AGM (Absorbent Glass Mat) technology is designed for vehicles with increased electrical demands, particularly those equipped with advanced start-stop systems.

Unlike conventional flooded starter batteries, AGM batteries retain their electrolyte within absorbent glass mat separators. This construction supports improved cycling durability, enhanced charge acceptance and reliable operation under partial state-of-charge conditions.

The Leoch 027AGM delivers up to three times the cycle life and twice the charge acceptance of conventional starter batteries, providing the performance characteristics required for compatible modern automotive applications.

Vehicles originally equipped with AGM batteries should be fitted with an appropriate AGM replacement rather than downgraded to conventional flooded technology.

Battery Compatibility & Replacement Guidance

Before purchasing the Leoch 027AGM 12V 60Ah battery, verify the battery requirements specified by your vehicle manufacturer.

Confirm the existing battery reference, AGM technology, electrical ratings, case dimensions, terminal polarity and mounting arrangement.

Some modern vehicles require battery registration or coding following replacement to ensure their battery management systems operate correctly.
