The difference between lead acid battery and gel battery
In fact, they are all lead acid batteries. The difference is in the construction. In general, the Lead acid battery is made up of plates, lead, and lead oxide (various other elements are used to change density, hardness, porosity, etc.) with a 35% sulfuric acid and 65% water solution. This solution is called electrolyte which causes a chemical reaction that produce electrons.

The Gel Cell and the AGM batteries are specialty batteries that typically cost twice as much as a premium wet cell. However they store very well and do not tend to sulfate or degrade as easily or as easily as wet cell. There is little chance of a hydrogen gas explosion or corrosion when using these batteries; these are the safest lead acid batteries you can use.

Lead acid batteries include the starting battery in your car. They also include deep cycle batteries that have thicker plates than starting batteries. Thinner plates (in the electrolyte) can deliver higher current, necessary for starting loads in a motor vehicle. Thicker plates are better suited to long slow discharges.

AGM: The Absorbed Glass Matt construction allows the electrolyte to be suspended in close proximity with the plates active material. In theory, this enhances both the discharge and recharge efficiency. Actually, the AGM batteries are a variant of Sealed VRLA batteries.

The characteristics of the Gel battery:

1.Colloidal State To Use
Sealing efficiency is more than 99.9%.

2. Minimal self-discharge
You can live a long-term storage of up to two years (20 ℃), kept four times the absorption-type batteries can be without additional power to immediately put into use.

3.Water loss rate is low
Water loss rate is only adsorption type battery 1 / 2, to effectively alleviate the early dry electrolyte.

4.Long service life
NPP gel battery design life of 12 years to save expenses.

5.Excellent deep-discharge cycle performance: Especially useful in the recycling, 100% deep discharge cycles and the life of more than 500 times, much higher than the absorption-type battery effectively improve the system reliability.

6.Over-discharge recovery performance
Over-discharge to the "0" V, still a good recovery, in order to maintain the 21 days after discharge 1CA, battery recovery capacity of 100%.

7.The application of environmental Canton
-40 ℃ -60 ℃ in the temperature range of use, performance, much higher than the adsorption cell.

Note:
1.C:means Ah value of battery's rated capacity.
2.When ambient temperature is below 15℃ or above 35℃,the recommended copensation factor is -3mV/℃/cell,(Floating Charge)or -4mV/℃/cell(Cycle)staring from the standard center point -25℃.
3.Battery temperature in charging should be in range of -15℃-50℃.

2.Discharge
Relationship between Discharge Current and Final Discharge Voltage.

Discharge Current(A) Final Discharge Voltage
6V/12V Series 2V Series
0.2C or below 1.75V/cell 1.80V
From 0.2C to 0.5C 1.70V/cell 1.75V
From 0.5C to 1.0C 1.55V/cell 1.70V
Above 1.0C 1.30V/cell 1.60V

Note:
1.See above table,Final Discharge Voltage should vary with the change of Discharge Current
Attention:When discharge,voltage must not be lower than its corresponding Final Discharge Voltage.
2.Immediate charge after discharge or overdischarge for retaining battery life.
3.Battery temperature in discharge should be in range of -15℃-50℃.
 

 

Attemions
1.Examine the appearance of the battery before use.
2.Store the battery in a cool place(best below 20℃ or 68℃F)
