Leoch 020AGM Start-Stop Car Battery – 12V 105Ah 950A

The Leoch 020AGM (L6AGM-020) is a high-capacity 12V 105Ah AGM start-stop car battery, delivering 950A cold cranking power (CCA) for reliable engine starting in vehicles with demanding electrical requirements.

Engineered with advanced Absorbent Glass Mat (AGM) technology, the 020AGM combines high starting performance, enhanced cycling durability and rapid charge acceptance to support compatible start-stop systems and modern vehicle electrical equipment.

Built in the large L6 battery case size (394 × 175 × 190mm), it is designed for vehicles requiring a 105Ah AGM starter battery with this physical configuration and electrical specification.

Key Features & Benefits

• 950A Cold Cranking Power – High starting current for dependable engine starting, including in cold-weather conditions.

• 105Ah High-Capacity Design – Provides substantial electrical storage capacity for compatible vehicles with demanding onboard systems.

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

• Up to 2× Faster Charge Acceptance – Supports rapid 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 vehicles with frequent engine restart requirements and increased electrical loads.

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

• Valve-Regulated Construction – Maintenance-free operation without routine electrolyte topping-up.

High-Capacity AGM Performance for Modern Vehicles

Modern vehicles equipped with start-stop technology and extensive onboard electrical systems place considerable demands on their batteries. Frequent engine restarts, repeated charging cycles and electrical consumption during engine-off periods require a battery engineered for sustained automotive operation.

The Leoch 020AGM combines 105Ah capacity with 950A cold cranking performance, providing the energy storage capacity and starting power required by compatible high-demand applications.

Its advanced AGM construction supports repeated discharge and recharge cycles, while enhanced charge acceptance enables efficient energy recovery during vehicle operation.

The battery is also engineered for partial state-of-charge conditions, supporting the operating characteristics of modern vehicle charging and energy management systems.

020AGM Replacement Battery – L6 Case Size

The 020AGM uses the large L6 automotive battery case, measuring 394mm long, 175mm wide and 190mm high.

This extended European case format is intended for installations requiring greater battery capacity and high cold-cranking performance.

The Leoch L6AGM-020 features a layout 0 terminal arrangement, terminal type 1 and B13 hold-down fixing, supporting installation in compatible battery trays and terminal configurations.

When replacing an existing 020AGM battery, confirm that the vehicle requires AGM technology and that the battery's electrical ratings, terminal polarity, mounting arrangement and physical dimensions match the original installation.

Matching case dimensions alone does not guarantee vehicle compatibility.

AGM Technology for Demanding Automotive Applications

AGM (Absorbent Glass Mat) technology is engineered to withstand the repeated cycling and increased electrical demands associated with modern start-stop vehicles.

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

The Leoch 020AGM delivers up to three times the cycle life and twice the charge acceptance of conventional starter batteries, supporting repeated engine restarts and demanding electrical operation.

Where a vehicle specifies AGM technology, an appropriate AGM replacement should be fitted rather than substituting a conventional flooded battery of the same dimensions.

Battery Compatibility & Replacement Guidance

Before purchasing the Leoch 020AGM 12V 105Ah battery, verify the battery requirements specified by your vehicle manufacturer.

Check the existing battery reference, AGM technology, capacity, cold cranking performance, L6 case dimensions, terminal configuration and hold-down arrangement.

Vehicles equipped with battery management systems may require battery registration or coding following replacement to ensure the new battery is correctly recognised.
