The Victron 12V/165Ah AGM Deep Cycle Batt. (M8) is designed for a range of applications that require consistent and reliable power. Featuring advanced Valve Regulated Lead Acid (VRLA) technology, this battery is fully sealed, ensuring that it requires no maintenance over its lifetime. The design includes safety valves that release gas only in the event of overcharging, providing peace of mind and safe operation.

Key Features:

• Valve Regulated Lead Acid (VRLA) Technology
• Exceptional Deep Discharge Recovery
• Low Self-Discharge
• Optimised Cycle Life
• Temperature-Resistant Design
• High Cold Cranking Amps and Reserve Capacity

Extended Service Life and Exceptional Deep Discharge Recovery

This battery stands out with its impressive service life and cycle capacity. With a design life of up to 12 years at 20 °C, it is engineered for both float and cycling conditions, making it suitable for standby and renewable energy applications. Its exceptional deep discharge recovery ensures that the battery can handle prolonged and deep discharges without significant loss of performance, although repetitive deep discharges should be avoided to maximise longevity.

Low Self-Discharge for Long-Term Storage

The BAT412151085 features a low self-discharge rate of less than 2% per month at 20 °C, thanks to its high-purity materials and lead calcium grids. This allows the battery to be stored for extended periods without needing a recharge, provided it is kept in cool conditions. This feature makes it ideal for backup power applications where the battery may sit idle for long durations.

Consistent Performance in Variable Temperatures

Temperature can greatly affect battery performance, but the BAT412151085 maintains a stable capacity across a range of temperatures. It is designed to perform efficiently even in challenging environments, although high temperatures will reduce its service life. With recommended temperature compensation during charging, it ensures optimal performance and longevity in all operating conditions.

Advanced Charging for Maximum Battery Life

The battery utilises Victron’s advanced 4-step adaptive charging curve, which significantly extends battery life compared to traditional charging methods. This adaptive system includes features such as Battery Safe Mode, variable absorption times, and storage mode, all designed to reduce gassing, minimise plate corrosion, and optimise the charging process based on the battery’s condition. This ensures that the BAT412151085 remains in peak condition, delivering reliable power whenever needed.
