There are Gels and there are Gels like there are AGMs and there are AGMs and AGMs are not a later invention as they were first developed in the mid 1980,s for the US Army and consisted of a few high recombination batteries from about four manufacturers.
They are low acceptance voltage but high input batteries .
The later AGM batteries from Asia cannot be compared with the original.
According to Dr Brown from Battery Energy Systems Australia the only ones that can build decent Gel Batteries are Aussies and the Super Gel Battery designed in conjunction with CSIRO and Telstra have an acceptance voltage equal to open flooded wet cell batteries and also have an acceptance to a higher operating temperature than most other batteries.
This can be proven by at least one Telstras remote operation of 11 repeater stations with in 300Kls of
Birdsville that used Battery Energy Gel batteries for the total communications for that area and have I believe been running in excess of 7 years now.
The Super Gel battery has a design life of 20Years in a standby situation and has a full replacement warranty of 5 years in a designed installation.
A battery is basically a dumb waiter for storing power and normally if not maintained and or not used in a designed application is generally murdered.
You cant blame a battery for that and that is not just Gel its all types.
