Product Overview

Product Overview

The 36-085-21 on tray 1603-B delivers 850 Ah at 72V in a flat-plate lead-acid configuration. The 43.5 x 43.5 x 22.625 (L × W × H) tray footprint balances energy density with broad equipment compatibility, while conventional flat-plate construction keeps acquisition cost lower than equivalent tubular alternatives.

Flat-Plate Construction

Applications

This battery is engineered for high-voltage Class I counterbalanced forklifts and heavy material-handling equipment where peak current capability and broad charger compatibility are valued over the deeper cycle counts of tubular designs. The 1603-B tray geometry has been verified against OEM compartment specifications for compatible equipment.
