The extremely powerful and reliable Ever Exceed’s Deep Cycle batteries perfectly fulfills the requirement for many different applications including telecommunications for many different applications including telecommunications, home medical equipment (HME)/ mobility, industrial and utility applications where frequent deep cycle are required and minimum maintenance is desirable. Our development team combines the market’s demand with design optimization, precision component selection and state-of-the-art manufacturing process to produce the most cost-effective battery solution for today’s applications.
Applicable operating temperature range: -10°C~+50°C
Ideal operating temperature range: +20°C~ +30°C
Storage time from a fully charged condition: 24 months at 25°C, for each 9°C rise, reduce the storage time by half.
Solar batteries are an intricate component for off-grid electrical systems such as solar, wind, and mini hydroelectric systems.
All these systems produce DC electrical which must be stored so that it may be used at a later time. In order to do this at the present time we use deep cycle batteries.
Deep cycle batteries are used because they have the ability to be recycled many times. This means that they can go from being charged to being discharged to 50% numerous times without damaging the batteries unlike that of other batteries such as cranking batteries which are used to start vehicles.
The innovative Gel Technology does not only combines the advantages of lower internal resistance of deep cycle battery , but also do have much much better thermal stability and longer cyclic life .

• The battery electrolyte contains fumed silica, and there is no flow, no leakage or no gradation of acid liquor. The battery slot and cover is made of ABS materials through hot seal. There is no risk of leakage during the utilization and transportation, and it is safe and reliable.
• The gel electrolyte is in dilute sol state when being injected. Excessive electrolyte can fill in all the space inside battery. Under circumstance of high-temperature and overcharge, the battery will not dry out. The gel battery has large heat capacity and good radiation performance. It is not easy to appear thermal runaway. The battery can work under severe environment.
• The grid of electrode plate is in radial structure, which is favorable for improving the utilization rate of active materials. Pb-Ca-Sn-Al alloy makes the positive plate have a good performance of corrosion proof and makes the negative plate have a high over-voltage of hydrogen evolution. Unique lead paste formula enables perfect recovery performance of battery recharging after deep discharging. The battery has strong cycle and duration performance, sufficient capacity and long life.
The terminal is in the structure of tin electrodeposited copper terminal, which is favorable for discharging battery with large current and is favorable for the reliability of connection between batteries. The terminal is sealed through fusion welding and second seal of resin sealant, and the seal reliability is high.
