12V lead-acid batteries(AGM) are widely used in RVs, trailers, and trucks as power sources for lighting, water pumps, fans, refrigerators (12V models), air conditioners, and other onboard electrical appliances.Due to its low cost, adaptability to a wide temperature range, simple maintenance, and compatibility with vehicle 12V circuits, it is widely welcomed by car owners and manufacturers.
However, lead-acid batteries have the disadvantages of large volume, low energy density, small capacity, and few cycles. A 12V lithium battery can compensate for these disadvantages. Lithium batteries are increasingly being used in 12V power supplies for RVs and trucks.
Here’s a clear comparison between 12V Lead-Acid Batteries and 12V Lithium Batteries (e.g., LiFePO₄) in table format:
| Feature | 12V Lead-Acid Battery | 12V Lithium Battery (LiFePO₄) |
| Energy Density | Low (~30-50 Wh/kg) | High (~90-160 Wh/kg) |
| Weight | Heavy (e.g., 20-30 kg for 100Ah) | Light (e.g., 10-15 kg for 100Ah) |
| Cycle Life | 300-500 cycles (50% DoD) | 2000-5000 cycles (80-90% DoD) |
| Depth of Discharge (DoD) | 50% recommended (deep-cycle: 80%) | 80-100% safe |
| Charging Speed | Slow (5-8 hours) | Fast (1-3 hours, higher charge current) |
| Efficiency | 70-85% | 95-98% |
| Voltage Stability | Drops under load | Stable voltage until depleted |
| Maintenance | Requires watering (flooded) or AGM sealed | Maintenance-free |
| Temperature Tolerance | Performance drops below 0°C or above 40°C | Wider range (-20°C to 60°C, but may need heating at low temps) |
| Cost | Low initial cost ($100-$300 for 100Ah) | High initial cost ($400-$1000 for 100Ah) |
| Lifespan | 3-5 years | 8-15 years |
| Safety | Risk of acid leaks, venting gases (H₂) | Safer (no leaks, BMS protection) |
| Environmental Impact | Toxic (lead, acid), recycling required | Cleaner, but recycling infrastructure developing |
| Common Uses | Car/RV starter batteries, backup power | RVs, solar storage, marine, high-performance |
