What are the differences between gel batteries and absorbed glass mat (AGM) batteries?
Both are recombinant batteries. Both are sealed and valve-regulated and are considered non-spill able and both are considered “acid-starved.” In a gel battery, the electrolyte does not flow like a normal liquid. IN AGM batteries all liquid electrolyte is trapped in a sponge-like matted glass fiber separator material.
The “acid-starved” condition of gel and AGM batteries protects the plates during heavy deep-discharges. The gel battery is more starved, giving more protection to the plate; therefore, it is better suited for super-deep discharge applications.
Due to the physical properties of the gelled electrolyte, gel battery power declines faster than an AGM battery’s as the temperature drops below 32°F. AGM batteries excel for high current, high power applications and in extremely cold environments.
Flooded batteries are more easily replaced by AGM batteries than Gel batteries as Gel batteries require different charging algorithms (mainly lower finishing voltages) to excel and live than do either AGM or Flooded types.

Uher Tonband:
Hoehere Strombedarf? Nein!
Temperatur? Ja. Aber Unter 0C gibts andere Problemen ausser Strom z.B. Fett und Lager d.h. sowieso nutzung einer mechanischen Tonband weit unter 0C ist heutzugtag nicht mehr ratsam.
d.h. keinen Vorteil von AGM ausser Preis.. aber Ladung?
Ladung? Wie sieht aus das Uher Z124-A1 Lader? Besser fuer GEL?
GEL ist auch besser fuer "Benutz bis leer"..
