Our 120Ah 12V Deep Cycle Battery is built to deliver reliable power across a wide range of conditions. With strong cycle life, low self-discharge, and excellent temperature resistance, it’s ideal for solar energy storage, inverter backup, UPS systems, and off-grid applications.
Key Technical Features
-
🔋 Capacity Stability Across Temperatures
Maintains over 80% rated capacity between 0°C and 40°C, ensuring consistent performance in both hot and cold climates. -
⚡ Low Self-Discharge
Retains over 80% of its capacity even after 6 months of storage at 25°C — meaning you can rely on stored power when you need it. -
🌡️ Charging Voltage vs Temperature
Optimized charging profile adapts to temperature changes, ensuring safe and efficient charging cycles. -
🔄 Deep Cycle Life
-
30% DOD (Depth of Discharge): Up to 1400 cycles
-
50% DOD: Around 800 cycles
-
100% DOD: 300+ cycles
(The lower the discharge depth, the longer the lifespan — making it perfect for solar storage where partial discharges are common.)
-
-
🧊 Temperature-Dependent Life Expectancy
At 25°C, floating service life can exceed 10 years, while performance remains stable in higher temperatures, though lifespan reduces gradually above 40°C. -
🔌 Open Circuit Voltage & Residual Capacity
Linear relationship between residual capacity and open circuit voltage ensures easy monitoring of charge status.
