Battery Specifications & Configuration
Matching a battery to a Hyster J30XNT, J35XNT, or J40XNT three-wheel electric forklift requires verifying the exact chassis model, system voltage, compartment dimensions, minimum and maximum battery weight limits, connector specification, and charging method.

Specifying an industrial battery for a Hyster J30-40XNT three-wheel electric forklift requires matching the exact truck model and compartment specifications published in the manufacturer's technical guide. The J30XNT uses a 21.5-inch long compartment, while the J35XNT and J40XNT use a 25.3-inch long compartment. Both chassis models support 36-volt and 48-volt electrical systems, each requiring specific cell counts, maximum allowable amp-hour capacities, physical dimension ranges, and designated connectors. In addition, the technical guide specifies exact minimum and maximum allowable battery weights for each compartment configuration, along with distinct lead cable lengths, gauges, and connector types for conventional versus rapid charging installations.
Inspect the truck nameplate to identify whether the forklift is a J30XNT, J35XNT, or J40XNT. The J30XNT chassis has a 21.5-inch (546 mm) compartment length (front-to-rear) with an overall width across the truck of 39.0 inches (990 mm). The J35XNT and J40XNT chassis feature a 25.3-inch (642 mm) compartment length with the same 39.0-inch width. Determining the exact model prefix establishes the allowable battery length ('Y' dimension) range: 20.0 to 21.2 inches for the J30XNT, and 23.5 to 25.0 inches for the J35XNT and J40XNT.
Check whether the forklift electrical system is configured for 36 volts or 48 volts. In conventional charging configurations (BCSSBC), 36V systems specify an 18-cell battery with a gray Anderson Power Products SB 350 connector (P/N 6320G1 or equivalent), whereas 48V systems specify a 24-cell battery with a blue Anderson Power Products SB 350 connector (P/N 6321G1 or equivalent).
Record the compartment hardware option: (a) with auxiliary counterweight platform (compartment height 23.9 in. / 607 mm, maximum battery height 'Z' 23.4 in. / 594 mm); (b) with battery rollers (compartment height 25.4 in. / 645 mm, maximum battery height 'Z' 24.9 in. / 632 mm); or (c) without auxiliary counterweight platform (compartment height 26.7 in. / 677 mm, maximum battery height 'Z' 26.1 in. / 664 mm). Confirm that the battery weight falls strictly within the published minimum and maximum limits for that configuration.
For conventional charging (BCSSBC), verify that battery leads are 20 inches (508 mm) long, sized at 2/0 AWG, and routed at position 'B'. For rapid/fast charging (BARFBC), the technical guide notes that a site survey is required to confirm the application and determine specifications; the setup requires dual cabling terminating in two Female EBC-320 DIN connectors (Anderson P/N A32503-0009 or equivalent) with 1 red conductor to (+) and 1 black conductor to (-), with 23-inch (585 mm) leads sized at minimum 3/0 AWG at position 'B' on XNT models.

The Hyster J30-40XNT technical guide defines exact battery compartment dimensions and allowable battery sizes based on the specific chassis model and compartment floor option.
The J30XNT chassis has a 21.5-inch (546 mm) compartment length, accepting battery lengths ('Y') from 20.0 to 21.2 inches (508 to 539 mm). The J35XNT and J40XNT chassis feature a 25.3-inch (642 mm) compartment length, accepting battery lengths ('Y') from 23.5 to 25.0 inches (597 to 635 mm). Across all models, the compartment width is 39.0 inches (990 mm), accommodating battery widths ('X') from 38.2 to 38.8 inches (970 to 986 mm).
The J30-40XNT series supports 36-volt and 48-volt electrical systems. On the J30XNT, 36V configurations use 18 cells (17 plates per cell) with a maximum 6-hour capacity of 880 Ah (30.6 kWh), while 48V configurations use 24 cells (13 plates per cell) with a maximum capacity of 660 Ah (30.5 kWh). On the J35XNT and J40XNT, 36V configurations use 18 cells (21 plates per cell) with up to 1,100 Ah (38.2 kWh), and 48V configurations use 24 cells (15 plates per cell) with up to 770 Ah (35.8 kWh). The source notes that battery amp-hour capacity is the maximum allowable per UL and that commercially available lead-acid batteries may not necessarily reach these limits.
For conventional charging (BCSSBC), the 36V system specifies a gray SB 350 connector (Anderson Power Products P/N 6320G1 or equivalent) and the 48V system specifies a blue SB 350 connector (Anderson Power Products P/N 6321G1 or equivalent), both with 20-inch (508 mm) 2/0 AWG leads at position 'B'. For rapid/fast charging (BARFBC), the technical guide states that a site survey is required to confirm candidate applications and determine battery and charger specifications; the connector requires dual cabling terminating in two Female EBC-320 DIN connectors (Anderson P/N A32503-0009 or equivalent) with 1 red conductor to (+) and 1 black conductor to (-), with 23-inch (585 mm) minimum 3/0 AWG leads at position 'B' on XNT models (26-inch minimum 3/0 AWG leads on XN models).
Hyster lift trucks meet the design and construction requirements of B56.1-1969 per OSHA Section 1910.178(a)(2) and comply with the B56.1 revision in effect at the time of manufacture. Standard truck construction carries UL Classification Type 'E' (with UL Type 'EE' optional), and the battery type designation is 'EO' (without cover). In addition to lead-acid batteries, the technical guide lists Thin Plate Pure Lead (TPPL) and Lithium-ion as options under Hyster Power Cellect™.
For service intake and replacement battery ordering, technicians must record the exact data plate information: model designation, truck serial number, system voltage, compartment hardware configuration, charging method, and verified battery weight against the minimum and maximum boundaries.
Applies exclusively to Hyster J30XNT, J35XNT, and J40XNT three-wheel electric counterbalance forklift models (and corresponding J30XN, J35XN, and J40XN four-wheel models where referenced in Technical Guide 1025HBC1SP001-E). Does not apply to other Hyster electric classes, ICE forklifts, or non-counterbalanced warehouse trucks.
