Core Competitive Advantage (Designed for Marine Environment)
1. Exceptional resistance to harsh marine environments, with top durability
The battery plates are made of anti-oxidation and anti-corrosion alloy material, and the shell is made of salt-resistant ABS engineering plastic. The fully sealed valve-controlled structure prevents electrolyte leakage, making it suitable for core marine scenarios with high humidity, salt spray erosion, and ship pitching and vibration; it is equipped with shock-resistant fasteners, ensuring stable operation even when the ship is tilted at 45 degrees, completely solving the pain points of ordinary batteries being prone to corrosion and damage at sea.
2. Dual performance power output, covering all power requirements of ships
It has dual functions of engine start-up and continuous deep-cycle power supply: The lead-acid model can instantly output a large current of 700A, and can easily start the main and auxiliary engines in low-temperature environments; The lithium battery model + lead-acid model can continuously power navigation, communication, fish finder, cabin lighting, water pump and other equipment, meeting all scenarios of ship navigation and operation, without the need to separately configure start-up batteries and energy storage batteries.
3. Maintenance-free and low operating costs, reducing the burden on end users
All product series are designed for maintenance-free, no need for fluid replenishment or balanced charging, completely eliminating the daily maintenance workload of crew members; The cycle life is much higher than that of ordinary industrial batteries, significantly reducing the frequency of battery replacement, and at the same time, there is no harmful gas emission, no leakage risk, reducing the corrosion and wear of ship equipment, and reducing the usage cost of end customers throughout the entire life cycle.
4. Authoritative certification + multiple safety protections, in line with maritime standards
The product has passed CCS (China Classification Society) certification, strictly following international maritime safety regulations; It is equipped with four protection mechanisms of overcharge, overdischarge, short circuit, and overtemperature, the lithium battery model also has an additional professional BMS battery management system, the lead-acid model adopts an explosion-proof pressure relief valve design, without open flames or toxic gases, and can be used in sealed compartments on ships to ensure safety.
This 100Ah marine battery can meet the power demands of various ships, covering a wide range of end markets and providing ample market space for trade, commercial cargo transportation, and factory support:

Common Questions and Solutions
Is the price higher than that of lead-acid?
Answer: The initial purchase price is approximately 30% higher, but within a 10-year lifespan, the total cost of replacement + maintenance is 60% lower than that of lead-acid, and it can increase the premium of the end product, making it more acceptable to customers.
2. Does it fit with existing equipment?
Answer: The 12.8V and 12V systems are compatible. The interface supports M8 standard terminals and can directly replace lead-acid; BMS supports mainstream communication protocols and can be connected to the ship's control system.
