The newer type of sealed non-spillable maintenance free valve regulated battery uses "Absorbed Glass Mats", or AGM separators between the plates. This is a very fine fiber Boron-Silicate glass mat. These type of batteries have all the advantages of gelled
A gel battery design is typically a modification of the standard lead acid automotive or marine battery. A gelling agent is added to the electrolyte to reduce movement inside the battery case. Many gel batteries also use one way valves in place of open ve
Advantage: low price: the price of lead acid batteries is just 1/4~1/6 of that of other types of batteries with a lower investment which most users could bear.
Disadvantage: heavy and bulk, low specific energy, strict on charging and discharging.
To determine if the battery in a system is experiencing a problem, disconnect all electrical loads, fully charge the batteries then disconnect all charging sources. Allow each battery in the system to stand on open-circuit for about one hour. Measure the
You will reduce the frequency of watering, but will cause a condition known as stratification where the specific gravity of the electrolyte is light at the top of the battery and heavy at the bottom. This condition results in poor performance and reduced
Undercharging: Continually operating the battery in a partial state of charge, or storing the battery in a discharged state results in the formation of lead sulfate compounds on the plates. This condition is known as sulfation. Both of these conditions re
