Comparison between Tubular Gel vs AGM VRLA
Parameter
Tubular Gel- WERBAT
AGM VRLA- Competition
Cycle Life
Higher (2400nos of cycles at 50% DOD, 6000nos of cycles at 20% DOD). Gel has higher acid attraction which avoids acid stratification
Low (1800nos at 50% DOD, 4000nos at 20% DOD)
Operating Temp
operating range between – 20°C to +50°C
above 27deg.C, an increase of 10°C can reduce battery life by 50% or more.
Plate Design
Tubular plate design works excellently in partial state of charge condition.
Flat Plate AGM series does not works well for deep cycle application
Deep Discharge
The stability against deep discharges is better in GEL systems, because of the extra microporous separator
not stable for deep discharge application
Warranty
WERBAT offers 36months
Competition offers majorly 24months warranty
Shelf Life
Low Self discharge rate allows for up to 2 years shelf life
generally battery to be stored within 6months.
*The above data shows advantages of Tubular Gel is best suited for Deep Cycle application.
