Product Overview
Product Overview
The 12-085-13 on tray 1859-B delivers 510 Ah at 24V in a flat-plate lead-acid configuration. The 28.25 x 15.437 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
Conventional flat-positive-plate construction uses pasted lead-antimony grids — distinct from PzS tubular gauntlet designs. Flat-plate cells deliver excellent peak current for moderate cycle counts, compatibility with virtually every charger profile already on the floor, and a lower entry cost than tubular. They are the workhorse choice for fleets that finish a single full discharge per shift rather than running multi-shift opportunity-charging cycles. Expect dependable service when paired with proper watering and an equalize-on-schedule maintenance routine.
Applications
This battery is purpose-built for Class III electric pallet jacks and walkie stackers, where reliable single-shift runtime and straightforward watering maintenance keep the unit on the floor. The 1859-B tray geometry has been verified against OEM compartment specifications for compatible equipment.
