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.
