| Expected Lifespan | 8 – 10 years | 1.5 – 3 years |
| Charging Time | 2 – 3 hours | 8 – 10 hours |
| Weight | 60% lighter | Heavy (30–50 kg) |
| Depth of Discharge (DoD) | Up to 95% | 50% (recommended) |
| Energy Efficiency | 95 – 98% | 70 – 80% |
| Maintenance | Zero maintenance | Regular water topping, terminal cleaning |
| Self-Discharge Rate | < 3% per month | 5 – 15% per month |
| Safety | BMS protected, no acid leaks | Acid spill risk, gas emissions |
| Environment | Eco-friendly, recyclable | Toxic lead, sulfuric acid |
| Total Cost of Ownership | 70% lower over lifetime | Higher (frequent replacement) |
| Warranty | Up to 7 years (DuraEdge) | 6 – 18 months typical |
Every metric that matters – lithium outperforms lead acid decisively.
DuraEdge batteries deliver 6000+ charge cycles compared to just 300-500 for lead acid. This means you replace your battery once instead of 10+ times over the same period.
A typical 48V 100Ah lithium pack weighs just 35-40 kg versus 120+ kg for lead acid. Less weight means better vehicle performance and lower structural stress on inverter installations.
Charge to 100% in just 2-3 hours vs 8-10 hours for lead acid. For e-rickshaws, this means more trips per day. For homes, faster power restoration after outages.
While upfront cost is higher, lithium batteries save 70% over their lifetime. Factor in no maintenance, no replacement every 1-2 years, and higher energy efficiency.
Every DuraEdge battery includes an advanced Battery Management System providing overcharge, over-discharge, short circuit, and thermal protection. No acid spills, no toxic gases.
LiFePO4 chemistry contains no toxic lead or acid. Fully recyclable at end of life. Choosing lithium is choosing a cleaner, greener, more sustainable future for India.
See how the initial investment in lithium pays for itself many times over.
