Leoch 115AGM Start-Stop Car Battery – 12V 80Ah 800A

The Leoch 115AGM (L4AGM-115) is a high-performance 12V 80Ah AGM start-stop car battery, delivering 800A cold cranking power (CCA) for reliable engine starting in compatible vehicles. Engineered with advanced Absorbent Glass Mat technology, it combines high starting performance, enhanced cycling durability and rapid charge acceptance for demanding automotive electrical systems.

Built in the L4/H7 battery case size (315 × 175 × 190mm), the 115AGM is designed for vehicles requiring an 80Ah AGM battery with this physical configuration and electrical specification.

Key Features & Benefits

• 800A Cold Cranking Power – High starting current for dependable engine starting, including in cold-weather conditions.

• Up to 3× Higher Cycle Life – Greater 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 demands.

• 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.

Engineered for Demanding Start-Stop Systems

Vehicles equipped with advanced start-stop technology require batteries capable of handling frequent engine restarts while supporting onboard electrical equipment.

The Leoch 115AGM delivers 800A cold cranking performance alongside the cycling durability and charge acceptance required for these operating conditions.

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

With 80Ah capacity, the 115AGM is suited to compatible vehicles requiring this higher-capacity battery specification, particularly where start-stop operation and electrical loads place sustained demands on the battery.

115AGM Replacement Battery – L4/H7 Case Size

The 115AGM uses the L4/H7 automotive battery case, measuring 315mm long, 175mm wide and 190mm high.

This larger European case format is used in a range of automotive applications requiring increased battery capacity and starting performance.

When replacing an existing 115AGM 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.

The L4/H7 case designation identifies the physical battery format but does not independently guarantee vehicle compatibility.

Why Choose an AGM Car Battery?

AGM (Absorbent Glass Mat) technology is engineered for modern vehicles with increased electrical demands, including 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 115AGM delivers up to three times the cycle life and twice the charge acceptance of conventional starter batteries, making it suitable for compatible applications involving repeated engine starts and demanding electrical operation.

Where a vehicle specifies AGM technology, the replacement battery should retain the required AGM specification rather than be downgraded to conventional flooded technology.

Battery Compatibility & Replacement Guidance

Before purchasing the Leoch 115AGM 12V 80Ah battery, verify the battery requirements specified by your vehicle manufacturer.

Check the existing battery reference, AGM technology, capacity, cold cranking performance, L4/H7 case dimensions, terminal configuration and mounting arrangement.

Some vehicles require battery registration or coding after replacement to ensure the battery management system correctly recognises the new battery.
