The FIAMM FG20721 battery is mostly designed to achieve optimal performance and protect from the disruptions of power. It has a high-quality battery, which ensures the leakage of the electrolytes- the leakage of electrolytes, which occurs due to the cause of terminals. The Batterie FIAMM has a feature of no maintenance. It perfectly sealed construction, and the gas recombination makes it Maintenance free. It uses the unique suspension of electrolytes incorporating the microfine glass mat (AGM). To retain its maximum amount of electrolyte present in the cell.
Features

It has the VRLA AGM system, and it's gas recombination technology of 99% internal recombination makes it a unique feature. These batteries have enough liquid to keep the designed glass mat wet. The glass mat was made to wick the mortar's electrolytes between the battery plates, in case it gets broken. No liquid leaks out. The AGM batteries prefer when a large quantity of the AMP is required. The life expectancy of it remains excellent in various cases., If it is allowed for a full charge and should not be discharged in between or recharged fully every 3-6 months. It is a gel cell battery.

It contains silica type gel, which is a material of thick paste. It allows the flow of electrons between the plates but did not leak in a gel battery if there is a broken case.

It doesn't offer the same power capacity as that of the Physical size AGM batteries. The Gel Cell Batteries excess in the slow discharge of rates with a little higher operating temperatures with excellent deep cycle capability. The battery needs to be charged efficiently, or one will suffer.
