Lithium Battery vs Lead Acid: Complete Comparison for Home Storage
Choosing the right battery technology is critical for your energy storage investment.
Energy Density
LiFePO4: 90-120 Wh/kg | Lead Acid: 30-50 Wh/kg. LiFePO4 is 3x lighter and smaller.
Cycle Life
LiFePO4: 3000-5000 cycles at 80% DoD | Lead Acid: 300-500 cycles. LiFePO4 lasts 10x longer.
Efficiency
LiFePO4: 95-98% round-trip | Lead Acid: 70-85%. More usable capacity.
Maintenance
LiFePO4: Zero maintenance | Lead Acid: Regular water topping required.
Cost Analysis
LiFePO4 has higher upfront cost but lowerTotal Cost of Ownership due to longevity.
Recommendation
For home energy storage, LiFePO4 is clearly superior for EU market.
