BCI maximum envelope

  • Length: 353 mm
  • Width: 175 mm
  • Height: 190 mm
  • Recorded aliases: H8, LN5, L5

These are group maximum dimensions, not actual measurements of every product.

Before ordering a battery

Check the actual battery position, chemistry, voltage, terminals, tray, hold-down, vent, CCA requirement and any BMS registration procedure. Group size alone does not approve a replacement SKU. High-voltage traction batteries are outside this guide.
