2V Deep Cycle Gel Battery 2000Ah Maintenance Free

Product Description

2Volt 2000Ah Deep Cycle Gel Battery Maintenance Free Series Connection
 
Description
Gel battery is a battery in which the electrolyte is in gel state, which belongs to a development classification of lead-acid battery, the method is to add gelling agent to sulfuric acid, so that the sulfuric acid electrolyte becomes gel state. Life is not the same: gel battery life is generally about twice as long as conventional lead-acid batteries, high temperature and low temperature characteristics are much better. Lead-acid battery uses a corrosion-resistant structure of lead-calcium alloy plate, the battery can be used for 10years floating charge.

Use of Deep Cycle Gel Battery

• Product name: Deep Cycle Gel Battery
• Check before charging and discharging: Before charging and discharging, the insulation of the charging equipment should be checked to see if it is good. Specific method: use 500V megohmmeter to measure the DC charging screen bus not less than 10MΩ.
• Initial replenishment of electricity: Before putting the battery into use after installation and inspection, it should be balanced and supplemented with 14.1V balanced charging voltage at 25℃ for a single battery, and charged in a constant voltage current-limiting way for the battery pack. The maximum charging current is set to 0.25C10A.

• Discharge: 1) 12V battery charging and discharging, 250Ah battery with a current of no more than 25A for 10 hours to discharge until the battery termination voltage of 10.8V or more, do not over discharge.
  2) During the discharge process, measure and record the battery voltage, discharge current and ambient temperature every hour, pay attention to the change of ammeter and battery voltage at any time, when the voltage drops to about 12.0V, change to half an hour test. When the measured voltage is 10.8v, stop discharging, open the discharge switch, the discharge is over. And record the discharge termination time, battery voltage, ambient temperature.
  3) After discharge, the battery should be recharged in time, to prevent acidification of the poles, the discharge-charging interval should not exceed 8 hours, so it must be balanced within 8 hours to replenish the electricity, the average charging voltage is set to 14.1V (the average of the measured value of the positive and negative terminals of the battery at 25℃), and the maximum charging current is set to 0.25C10A. The battery will run normally with the float charging voltage of 13.5V. Battery 13.5V.

  4) After discharge, check the discharge capacity at 25℃, it should be not less than 85% of the rated capacity, i.e. 12V250AH battery is not less than 212.5Ah.

• Temperature compensation: The above current and voltage setting values are the standard values when the ambient temperature is 25℃, if the gel battery working temperature is beyond the range of 20℃-30℃, the floating charge and average charge voltage should be corrected accordingly, the corrected voltage is, that is, for every 1℃ increase in temperature, the floating charge voltage is reduced by 5.5mV, and for every 1℃ decrease in temperature, the floating charge voltage is increased by 5.5mV.
