12V 20Ah Sodium-Ion Battery: Safe, Cold-Resistant & Cost-Effective for RV/Solar/Backup Power

12V 20Ah Sodium-Ion Battery – Safe, Sustainable, High-Performance

Featuring excellent safety (no thermal runaway), wide operating temperature (-20°C to 60°C), and over 3,000 cycles, our 12V 20Ah sodium-ion battery offers a cost-effective, eco-friendly alternative to lead-acid and lithium-ion. Lightweight, fast-charging, and cobalt-free—ideal for e-bikes, energy storage, and backup power.

Q1: What is the cycle life of this 12V 20Ah sodium-ion battery?

A: This battery delivers over 3,000 full charge-discharge cycles at 80% depth of discharge (DoD) while retaining more than 80% of its original capacity. With proper use, it can last 3+ years in typical applications like solar storage or light EVs.

Q2: How does it perform in cold temperatures?

A: Sodium-ion chemistry offers excellent low-temperature performance. The battery operates reliably from -40°C to +60°C. Even at -20°C, it maintains >85% of its room-temperature capacity, making it ideal for outdoor and winter applications.

Q3: Is this battery safe compared to lithium-ion?

A: Yes—significantly safer. Sodium-ion batteries are inherently more stable, with no risk of thermal runaway. Our 12V 20Ah model has passed rigorous safety tests (including nail penetration, overcharge, and short-circuit) and features built-in BMS protection. It’s also rated IP67 for dust and water resistance.

Q4: How long does it take to charge?

A: With standard charging (0.5C), it takes about 2 hours to fully charge. Using fast charging (1C), you can reach 80% state of charge in just 15–20 minutes. Always use a compatible sodium-ion charger for optimal performance and safety.

Q5: Can I use this battery as a direct replacement for a 12V lead-acid or LiFePO₄ battery?

A: In most cases, yes. The nominal voltage (12V) and form factor are designed to be drop-in compatible with existing 12V systems (e.g., solar setups, UPS, e-bikes, or marine applications). However, please verify your system’s voltage range and charger compatibility—sodium-ion batteries typically operate between 10V–14.6V.

Q6: Does it require maintenance?

A: No. This is a maintenance-free, sealed battery with an integrated Battery Management System (BMS) that handles cell balancing, overcharge/discharge protection, and temperature monitoring automatically.

Q7: What certifications does this battery have?

A: It complies with international standards including UN38.3, CE, RoHS, and IEC 62619, ensuring safety, environmental compliance, and reliability for global markets.

Q8: What is the warranty?

A: We offer a 3-year limited warranty covering manufacturing defects and premature capacity loss under normal operating conditions.
