1.1 Description
The AlphaCell GelCell battery is a lead acid battery that facilitates an oxygen recombination
cycle. The net result, under normal conditions, is minimal gas emission and water loss from
the electrolyte. The electrolyte is immobilized in either a gel form or is absorbed within an
absorbent separator between the plates. Consequently, there is no requirement to add water
to the cells or to measure the electrolyte specific gravity.
You can connect multiple strings of batteries in parallel. This provides a system whose
capacity equals the sum capacity of all the strings. For example, in Fig. 3, two 36V 90Ah
capacity strings are connected in parallel to provide a nominal 36V at 180Ah.
A 12V battery is made up of six 2V cells internally connected to provide 12 volts.
The battery system is a group of 12V batteries connected in a series string to provide a
higher voltage system. In Fig. 2, three of the nominal 12V batteries are connected in series to
provide an 18 cell system with a nominal voltage of 36V.

(For illustration purposes, a 36Volt string is shown. 48Volt strings are also available)
Alpha highly recommends fusing in single and parallel string configurations.
