What are Gel Batteries?
A gel cell battery is a battery that uses a sulfuric acid that has been mixed with fumed silica to create a gel-like substance that is immobile. Because of the GEL cell, the battery does not have to be kept upright and the electrons can flow between the plates without the threat of spilling.
Gel batteries are the safer lead acid batteries because they release less hydrogen gas from their vent valves. This makes them safer to install where there is limited ventilation. Hydrogen release or gassing is a minor safety concern with flooded lead acid batteries.
GEL batteries are the best for testing or less expensive solar projects. Lithium
batteries are good for long-time installation and help avoid frequent substitution.
Things like quick charging, high discharge, or other intense situations are all.
likely to cause serious damage to a gel battery, making it fail even if its barely used.
Lithium Ion batteries
They have an extremely long lifespan due to aspects such as the battery
management, very low self-discharge, the lack of memory effect and a discharge of up 20 %.
