The LiFePO4 batteries VS Lead-acid batteries:
| Haicen LiFePO4 batteries | VS | Old technology-Lead-acid batteries |
| Stable discharge condition | Low temperature condition | Unstable discharge condition |
| 3,500 times | Cycle life | ＜500 times |
| Around 10 years | Design life | 3 years |
| As little as 3.5 hours | Charging time | Up to 8 hours |
| No memory, opportunity charge | Charge frequency | Must charge after use |
| Multiple built-in protections, high thermal and chemical stability | Safety | Gas inside may cause explosion |
| 85% or more nominal capacity achieved at high working load | Available capacity | Only 30%~50% nominal capacity achieved under high working load |
| Maintenance-free | Maintenance | Regular water-adding and inspection required |
| Pollution-free | Eco-friendly | Lead is a toxic substance, may cause human lead poisoning |
| Extremely low | Energy loss | 15% |
Key Points for Quality Control:
Cell match: More strict cell matching standard, the difference of lnternal resistance is 1mΩ and voltage is 5mV.
Automatic cells welding: Cells are assembled by Automatic welding equipments to ensure the quality reliability and consistency.
100% Cycle test: All battery packs are 100% cycle tested (Fully Discharged→Fully Charged→Fully Discharged→60% Charged) before package and all test reports are stored.
Unique tracking number: All battery packs are lasered an unique number on the case side for quality tracking.
Certifications:
