Deep Cycle Long Life 6 Evf 32 Battery Graphene 12V 32AH EV Battery

The 6-EVF-32 is an upgraded electric vehicle battery that integrates graphene modification technology based on traditional valve-regulated maintenance-free lead-acid batteries. Specifically designed for electric bicycles and electric scooters, it focuses on core advantages of "longer lifespan, stronger adaptability, and greater convenience," catering to daily high-frequency commuting and medium-short distance travel needs for households.

1. Basic Specifications & Technical Positioning

• Model Interpretation: "6" stands for 6 individual cells (total voltage of 12V); "EVF" refers to a valve-regulated structure dedicated to electric vehicles; "32" indicates a rated capacity of 32AH. It can meet the daily range demand of 15-30 kilometers for most household electric vehicles.
• Core Upgrade: Graphene composite materials are added to the electrode plates or electrolyte. Leveraging graphene’s high conductivity and high stability, it addresses the pain points of traditional lead-acid batteries (short lifespan and poor low-temperature performance) while retaining the convenience of maintenance-free operation.

2. Core Advantages Empowered by Graphene

1. Longer Cycle Life: Graphene enhances the adhesion of active substances on electrode plates, reducing substance shedding during charging and discharging. Its cycle life reaches 500-800 charge-discharge cycles (compared to 300-450 cycles for ordinary 32AH lead-acid batteries). With one charge per day, it can operate stably for 2.5-3.5 years, reducing the replacement frequency by approximately 20%.
2. Stronger Environmental Adaptability: Graphene improves low-temperature conductivity. Within the temperature range of -15℃ to 45℃, its discharge capacity retention rate exceeds 80% (vs. 70%-75% for ordinary models). It enables smoother startup at low temperatures in winter and avoids sudden range drops under high temperatures in summer.
3. Faster Charging Efficiency: Benefiting from graphene’s high electron transfer rate, it supports "short-term fast charging for energy replenishment" — charging at room temperature for 1.5-2 hours can restore approximately 60% of the power, making it more flexible for emergency charging scenarios (e.g., sudden outings).

3. Safety & Convenience Design

• Maintenance-Free Feature: It inherits the valve-regulated sealing technology, eliminating the need for adding electrolyte or distilled water. This makes it suitable for individual users and small-to-medium repair shops.
• Safety Protection: The shell is made of UL 94 V-1 flame-retardant material, equipped with a one-way safety valve (pressure threshold: 35-45kPa). It automatically releases pressure to prevent case bulging and acid mist leakage, ensuring safety during bumpy rides.
• Compliance Assurance: It meets the ISO9001 Quality Management System and RoHS limits for hazardous substances. Some specifications have passed CE certification, ensuring compliance in terms of material environmental friendliness and electrical safety.
