Service life and charging method of the deep cycle gel battery

Colloidal lead-acid deep cycle gel battery is an improvement of ordinary lead-acid deep cycle gel battery with liquid electrolyte. The colloidal electrolyte is used to replace sulfuric acid electrolyte, which is better than an ordinary deep cycle gel battery in safety, power storage, discharge performance, and service life.

 Charging method of the deep cycle gel battery

1. Constant current charging method
   The constant current charging method is a charging method to keep the charging current intensity unchanged by adjusting the output voltage of the charging device or changing the series resistance with the battery. The control method is simple, but the acceptable current capacity of the deep cycle gel battery decreases gradually with the charging process. In the later stage of charging, the charging current is mostly used to electrolyze water and produce gas, resulting in an excessive gas outlet. Therefore, the stage charging method is often used.

2. Constant voltage charging method

The voltage of the charging power supply remains constant throughout the charging time. With the gradual increase of the deep cycle gel battery terminal voltage, the current decreases gradually. Compared with the constant current charging method, the charging process is closer to the optimal charging curve. Fast charging with constant voltage, because the electromotive force of the deep cycle gel battery is low and the charging current is large at the initial stage of charging, the current will gradually decrease with the progress of charging. Therefore, only a simple control system is needed.

This charging method has little electrolytic water and avoids deep cycle gel battery overcharge. However, in the initial stage of charging, the current is too large, which has a great impact on the service life of the deep cycle gel battery, and it is easy to bend the deep cycle gel battery plate, resulting in the scrapping of the deep cycle gel battery. Given this disadvantage, constant voltage charging is rarely used, only when the charging power supply voltage is low and the current is large. For example, in the process of automobile operation, the deep cycle gel battery is charged by the constant voltage charging method.

Factors of affecting the service life of the deep cycle gel battery

One is the application environment. If the ambient temperature is high, generally speaking, the service life will be reduced by half for every 10 degrees increase based on 25 degrees; There are also charging conditions. If it is often undercharged and less charged than discharged, it will soon break down. The charging capacity of a single cycle should be more than 1.2 times the discharge capacity. As well as the discharge depth. For example, if only 30% of the actual capacity of the deep cycle gel battery is discharged each time, it can be recycled more than 1500 times, that is, about 4 years, but if it is 80% each time, it will be only more than one year,100% is about a year.

Good deep discharge cycle performance. When the deep cycle gel batteryis recharged in time after deep discharge, the capacity can be recharged 100%, which can meet the needs of high-frequency and deep discharge. Therefore, its application range is wider than that of the lead-acid deep cycle gel battery.
