Product Overview
Built around the same 13-plate, 85 Ah-per-plate cell architecture as its GT18-85-13 sibling, the GT18-85-13-3 offers 595 Ah at 36V with a heavier ballasted tray at 1,475 lbs — the same 38 × 15.5-inch footprint but with additional mass to satisfy stricter OEM counterweight requirements on certain narrow-aisle lift truck models. This configuration is the right choice when counterweight compliance is as important as capacity and the standard 1,400 lb tray falls short of the equipment's minimum battery weight specification.
- Voltage: 36V
- Capacity: 595 Ah
- Plates per cell: 13
- Dimensions (L×W×H): 38 × 15.50 × 22.81 in

Protected by a 5-year / 60-month capacity warranty, the GT18-85-13-3 is calibrated for fleets where ballast compliance is a hard requirement — contact us to confirm fitment for your 36V equipment.
