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.

Prismatic cells offer higher energy density within a compact rectangular design, making them ideal for space-constrained applications. They provide better heat dissipation due to larger surface area, enhanced structural stability, and simpler integration into battery packs. Compared to cylindrical cells, prismatic designs also reduce internal resistance for improved efficiency and support more flexible terminal placement for easier installation.
Yes. Our 12V prismatic LiFePO4 batteries are designed as drop-in replacements for lead-acid batteries (AGM/gel/flooded). They feature standardized terminal layouts (e.g., M8 threads), compatible voltage profiles (12.8V nominal), and built-in BMS to ensure seamless integration with automotive, solar, or marine systems without requiring additional components or modifications.
Their compact size and high reliability make them ideal for:
Solar energy storage: Off-grid and hybrid systems.
Marine/RV: Powering electronics, lighting, and auxiliary systems.
UPS/Backup power: Critical backup for servers and medical devices.
Electric mobility: Golf carts, scooters, and mobility chairs.
