FAQ's

GEL Vs AGM Lead Acid Batteries

AGM (Absorbed Glass Mat) - These batteries contain only enough liquid to keep the specially designed glass mat wet. The glass mat is made to wick the battery electrolytes between the battery plates. If the AGM battery is broken no free liquid leaks out.

AGM batteries are preferred when a large amount of amps are required. The life expectancy remains excellent in most cases, if they are not discharged more than 60% between recharges and/or recharged fully every 3-6 months.

Gel Cell Batteries - These batteries contains silica type gel, which is a thick paste like material. It allows the electrons to flow between plates, but will not leak in a gel battery if the case is broken.

Gel Cell Batteries don't offer the same power capacity as do the same physical size as AGM batteries. Gel cell batteries excel in slow discharge rates and slightly higher operating temperatures and with excellent deep cycle capability. Recharging these batteries must be done correctly or it will suffer a premature failure.

Are Lead Acid Rechargeable Batteries Harmful?

Lead acid batteries contain chemicals that have the potential to be harmful to both your health and the environment. They contain lead which is a highly toxic metal and sulfuric acid which is a corrosive electrolyte solution.

Proper handling procedures must be followed at all times.

How to dispose of Lead Acid Batteries?

These batteries do contain hazardous chemicals so recycling is the only way to dispose of them. Recycle responsibly, a wide range of schemes are available.
