12 Volt Gel Cell Rechargeable Battery , Motorbike Gel Battery Corrosion Resistant

Gel battery (also called "gel cell") is a VRLA battery with a gelified electrolyte; the sulfuric acid is mixed with fumed silica, which makes the resulting mass gel-like and immobile. Unlike a flooded wet-cell lead-acid battery, these batteries do not need to be kept upright. Gel batteries reduce the electrolyte evaporation, spillage (and subsequent corrosion problems) common to the wet-cell battery, and boast greater resistance to shock and vibration. Chemically they are almost the same as wet (non-sealed) batteries except that the antimony in the lead plates is replaced by calcium, and gas recombination can take place.

Lead acid battery advantages & disadvantages

Although lead acid batteries are widely used because they have a number of distinct advantages, they also have several major disadvantages. All these need to be considered when deciding upon whether to use this technology or not.

Lead Acid Battery Advantages

1, Mature technology

2, Relatively cheap to manufacture and buy (they provide the lowest cost per unit capacity for rechargeable cells)

3, Large current capability

4, Can be made for a variety of applications

5, Tolerant to abuse

6, Tolerant of overcharging

7, Wide range of sizes and specifications available

8, Many producers worldwide

Lead Acid Battery Disadvantages

1, Fails after a few years use lifespan typically 300 - 500 cycles

2, Cannot always be used in a variety of orientations

3, Corrosive electrolyte (can cause burns to people and corrosion on metalwork)

4, Lead is not environmentally friendly

5, Acid needs disposing of with care

6, Not suitable for fast charging

7, Must be stored in charged state once electrolyte introduced

8, Typical charging efficiency only around 70%
