Storage and installation

1.Fortune Power battery is not in use should remove the cable, pole jacket cover and wipe clean;

2.once every three months for Fortune Power battery to maintain charging, constant voltage charging method for limiting law, the initial charging current is 0.1CA, the charging voltage is 2.4V / single cell (25 ℃ when);

3.Fortune Power battery should be stored in dry and ventilated place, away from direct sunlight and away from heat sources;

4.when handling batteries even force, the force of the housing portion of the battery to avoid damage to the pole;

5.the installation should use insulated tools to prevent click.


Chengyu Maintenance-free lead-acid battery

• Ultra-heavy grid design

The positive grid thickness reaches 6.8 mm, and the corrosion life is 20 years.

• Lead and calcium multi-component high purity alloy

It does not generate pollution to the environment and surrounding facilities, and minimizes the self-discharge and water loss of battery arising from the material formulation.

• Elongation design of polar plate

The elongation space of polar plate is reserved to prevent early failure of the battery due to elongation of the polar plate.

• Adding the polar plate protective sleeve 

It prevents top or bottom short circuit of the battery to improve the battery system reliability.

• Flame retardant design

The whole system adopts fame retardant design to eliminate the hazards of battery combustion and explosion.

• Double-layer acid filtering explosion-proof safety valve

The safety valve shows the explosion-proof and acid filtering sealing performance, and the valve opening pressure is 10-20 KPa.

• Heat dissipation design

The high strength thin wall PP shell + steel frame design is adopted so that heat in the battery can quickly spread to the steel frame. The special cooling channel on the steel frame can quickly transfer heat to the outside and effectively prevent thermal runaway of the system.

• Flexible installation modes

Batteries can be placed vertically or horizontally, installed in multiple layers and multiple columns like building blocks, or installed in the cabinet type.

Shipping and Packing

1.Each battery lay in its own carton 

2.Cartons stand on the 1M*1M pallet and protected by the waterproof plastic film. 

3. Shipping way: Sea shipment, fast, cheap and safe.

How to choose good valve regulated lead acid battery?

There are several factors that should be taken into account when determining

the total cost of ownership over the life of the battery.

1.Price: A battery with a low price is always attractive, but if low price comes

at the expense of quality and battery life, the need for frequent battery replacements

could boost the cost over time. That’s why it’s important to consider issues other than

price when making the decision.

2.Capacity: Battery capacity is important because it’s a measure of the amount of energy

stored in the battery.

3.Voltage: The battery bank voltage must be considered to ensure it matches the system requirements. The battery bank voltage is often determined by the inverter specifications

if installing a DC-to-AC system or by the voltage of the loads in a DC system.

4.Cycle Life: The most critical consideration is cycle life, which provides the number of discharge/charge cycles the battery can provide before capacity drops to a specified

percentage of rated capacity. Batteries from different manufacturers may have the same

capacity and energy content and be similar in weight. But design, materials, process and

quality influence how long the battery will cycle.
