Specification:
Gel battery is a battery filled up with a special gel-type electrolyte. Gel batteries are non-spillable, completely sealed and maintenance free - one of the safest batteries. They have much longer service life compared to standard wet-cell batteries due to lower degradation and internal corrosion. Gel batteries hold charge very well and have much lower self-discharge rate.
