Remarks: The recommended charge voltage for this sodium ion battery is 15.6V. When using a charging system with a voltage between 13V and 14.6V, the battery can be charged to approximately 85% of its capacity. To reach a full 100% charge, upgrading to a 15.6V charging system or using a dedicated 15.6V charger is recommended. | |
Designed for general 12V engine-starting applications, the 80Ah sodium-ion battery combines 900 CCA with a compact 260 × 175 × 220 mm case for reliable everyday starting and cold-weather operation.
Suitable for cars, vans, pickups, and other 12V vehicles requiring reliable starting power and higher cranking capability.
Provides dependable starting power for leisure boats and other small marine engines where compact installation and low-temperature performance are important.
Supports generator engines that require reliable starting after extended standby periods or under changing ambient temperatures.
A practical starting solution for maintenance vehicles, service equipment, and other 12V engine-powered utility applications.
Different battery chemistries offer different advantages for engine-starting applications. The right choice depends on cranking demand, temperature, cycle life, weight, and charging-system compatibility.
Feature | Lead-Acid | Lithium-Ion | Sodium-Ion |
|---|---|---|---|
Cold-Weather Performance | Starting performance typically decreases as temperature drops | Performance varies by lithium chemistry and battery design | >80% capacity retention at −20°C; discharge down to −30°C |
Cranking Output | Mature starting technology | High-current output depends on cell and pack design | 900 CCA; 400A peak discharge @ 5s |
Cycle Life | Typically 300–500 cycles | Typically 3,000–5,000 cycles | Up to 4,000+ cycles under specified conditions |
Weight | Generally heavier | Typically lightweight | Lower weight than conventional lead-acid batteries |
Battery Management | Typically no integrated BMS | BMS normally required | Integrated BMS |
Charging Compatibility | Broad compatibility with conventional 12V systems | Requires a compatible charging profile | Recommended charging voltage should be matched to the battery |
For applications requiring strong cold-weather cranking and frequent cycling, sodium-ion can provide a practical battery alternative. Before replacement, check CCA, case size, terminal layout, charging voltage, and operating temperature.
Choose the right model based on capacity, required CCA, and peak starting current.
Model | Capacity | Starting Current | Peak Discharge | Selection Guide |
50Ah | 600 CCA | 200A @ 5s | Compact option for lower starting-current requirements | |
60Ah | 800 CCA | 200A @ 5s | Higher cranking output with moderate capacity | |
70Ah | 800 CCA | 200A @ 5s | More capacity while maintaining 800 CCA | |
80Ah | 900 CCA | 400A @ 5s | Higher cranking and peak-current demand | |
90Ah | 1000 CCA | 400A @ 5s | Higher starting-current requirement | |
100Ah | 1200 CCA | 400A @ 5s | Highest capacity and cranking output in this range |
