Deep Cycle GEL Battery

As the number of battery customers around the world continues to increase, many customers report that due to unstable power supply during the day and short mains power hours, the battery power is consumed very quickly and cannot be fully charged, resulting in a shortened battery life and the need for frequent replacement. This is because if the battery is deeply discharged at night and cannot be fully charged during the day, the battery will sulfate after a few months of operation and the capacity will decrease rapidly, causing the battery to lose power quickly.
To this end, our R&D personnel have specially developed a tubular deep cycle gel battery, using tubular plates to replace the old plate design, which improves the utilization of the plates. Even if the battery is not fully charged, there will be no sulfation problem. This greatly extends the service life of the battery and is more suitable for countries with widespread power shortages.
The tubular deep cycle gel battery is a valve-controlled tubular gel battery that uses fixed gel and tubular plate technology. It uses a die-cast positive grid and a patented formula of active materials. It is designed and manufactured beyond DIN standard values and has high reliability. And high performance, the floating design life is more than 25 years at 25℃, which is more suitable for cyclic use under extreme working conditions. This maintenance-free battery uses a unique grid alloy, a special gel formula and a unique positive and negative lead paste ratio, and has excellent deep cycle performance and over-discharge recovery capabilities. The ultra-high-strength separator is used to prevent short circuits. There is no acid mist gas precipitation and no electrolyte spillage during use. There are no elements harmful to the human body during the production process. It is non-toxic and pollution-free. It prevents traditional lead-acid from using a large amount of electrolyte during use. Leaking and leaking acid batteries.

CPSY® Deep Cycle GEL Battery Details

When compare with peers, CPSY® Deep Cycle GEL Battery advantages as below:

1. It adopts flame retardant (UL94HB and UL 94-0ABS) and waterproof, which is better than PVC and other ABS shells.

2. Made of 99.997% pure lead, which is better than 60%-70% lead or recycled lead and has a long service life.

3. Use pure copper terminals, which have good electrical conductivity and are better than ordinary copper terminals.

4. Use high-quality AGM material partitions to absorb moisture from adverse factors and are more stable and durable than PP/PE/PVC partitions.

5. Use silicone safety valve to prevent corrosion, discharge excess gas, and prevent explosion.

6. Using high-tech silicone gel electrolyte technology to avoid ultra-deep discharge and acid stratification.

7. The GEL in the battery uses silica gel imported from Evonik Degussa, Germany, an internationally renowned brand.


1. Avoid overcharging. For sealed designs, if overcharged, oxygen and hydrogen will precipitate through the battery safety valve, causing the electrolyte to dry out, reducing battery capacity and shortening life. If the battery is continuously charged, a layer of sulfate will accumulate on the battery plates. Battery performance decreases and lifespan decreases.

2. Do not use constant current charging method for gel batteries. For gel batteries, constant voltage and current-limiting charging is the best charging method, ensuring that the charging voltage per cell is at least 2.3V, but not exceeding 2.35V (20°C).

3. It is recommended to use constant voltage charging method. The bandwidth display tolerance is ±30mV/single cell, which is suitable for continuous charging and recycling.
