Leoch 012AGM Start-Stop Car Battery – 12V 50Ah 570A

The Leoch 012AGM (L1AGM-012) is a high-performance 12V 50Ah AGM start-stop car battery, delivering 570A cold cranking power (CCA) for reliable engine starting in compatible vehicles. Engineered with advanced Absorbent Glass Mat technology, it provides enhanced cycling durability, rapid charge acceptance and dependable performance under demanding automotive operating conditions.

Built in the compact L1 battery case size (207 × 175 × 190mm), the 012AGM is designed for vehicles requiring this AGM battery specification, including compatible start-stop applications.

Key Features & Benefits

• 570A Cold Cranking Power – Strong, reliable engine starting performance, including in 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 – Rapid energy recovery to support frequent engine restarts and modern vehicle electrical demands.

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

• Start-Stop Ready – Designed for vehicles with frequent engine restart requirements and increased electrical loads.

• Partial State-of-Charge Capability – Engineered to perform under partial state-of-charge (PSoC) operating conditions.

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

Engineered for Start-Stop Performance

Modern start-stop vehicles place significantly greater demands on their batteries than conventional starting systems. Frequent engine restarts, continued operation of onboard electronics and repeated charging cycles require a battery engineered for more than occasional engine starting.

The Leoch 012AGM combines high 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 improved charge acceptance enables efficient energy recovery during vehicle operation. This makes the 012AGM particularly suited to compatible start-stop vehicles and applications involving frequent engine starts.

012AGM Replacement Battery – L1 Case Size

The 012AGM is a compact L1 AGM car battery measuring 207mm long, 175mm wide and 190mm high.

Its L1 case format, layout 0 terminal arrangement and B13 hold-down configuration are designed for vehicles requiring this physical battery specification.

When replacing an existing 012AGM battery, confirm that the original battery's technology, dimensions, terminal polarity and electrical ratings match the replacement requirements.

A battery with matching dimensions is not necessarily interchangeable if its technology or electrical performance differs.

Why Choose an AGM Car Battery?

AGM (Absorbent Glass Mat) technology is engineered for vehicles with increased electrical demands, particularly those equipped with 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 operation under partial state-of-charge conditions.

The Leoch 012AGM 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 012AGM 12V 50Ah battery, verify the requirements specified by your vehicle manufacturer.

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

Some modern vehicles also require battery registration or coding after replacement to ensure the battery management system operates correctly.
