Deep cycle Gel Batteries

A Gel Battery (also known as a "gel cell") is a rechargeable with a . Unlike a traditional wet-cell lead-acid battery, these batteries do not need to be kept upright (though they cannot be charged inverted). In addition, gel batteries virtually eliminate the electrolyte evaporation, spillage (and subsequent issues) common to the wet-cell battery, and boast greater resistance to extreme temperatures, shock, and vibration. As a result, they are primarily used in automobiles, boats, aircraft, and other motorized vehicles. These batteries are often colloquially referred to as sealed lead-acid (SLA) batteries due to their non-leaking containers, but they are not completely sealed; the valve regulation system allows for gas to be expelled. Chemically they are the same as wet (non sealed) batteries except that the in the lead plates is replaced by calcium. This preserves the mechanical characteristics but renders the construction far less prone to gassing. The battery type is often referred to as a Lead-Calcium battery.

♦Electrolyte Uniform Distribution 
Gel series battery is manufactured with high-quality gaseous silica to make the electrolyte in uniform distribution.
No Leakage
Curdled gaseous silica used in Gel batteries can immobilize the electrolyte and make the plates react evenly.
Longer Cycle Service Life
Deep Cycle design (high-density active material and thick plates) & special 4BS lead paste technology prolongs the cycle service life.
Excellent Deep Cycle Ability
Unique grid alloys & special positive/negative lead paste formulations makes the battery perform excellent in deep cycle using and recover quickly upon over discharging and extend the float service life.
Low Self Discharge
Using high purity raw materials and gel electrolyte ensures MCA batteries have less self-discharge.  
Environmental & Non-polluting
Gas Recombination technology ensures the battery high seal reacting rate, which can prevent the acid fog from separating out.
Safe & Reliable
Efficient venting system automatically release excess gas when the pressure rises above the normal level & reseals the valves when it returns to the normal rate, which can protect the battery from bursting.
