Product Overview
The GT18-85-21 scales the 36V flooded tubular platform to 935 Ah via a 21-plate per cell configuration (10 positive), serving large-format Class II Class II lift trucks and AGV systems running extended multi-shift operations. Weighing 2,210 lbs in a 38.25 × 24.5-inch tray, it combines the highest single-shift energy reserve with the ballast mass required by heavier narrow-aisle equipment — tubular positive plates maintain output stability across the full warranty life on a chemistry that tolerates the deep daily discharge common in 36V Class II environments.
