Upgrade kit P-106000220 facilitates replacing one existing two-row battery tray assembly with two single-row

battery assemblies.

The replacement trays contain nine batteries each, such that it takes two single-row trays to complete one

string. Each single-row battery tray has one circuit.

Each kit (P-106000220) includes two single-row battery trays and two harness adapters. Only one harness

adapter is needed for the installation; the second harness adapter is a spare.
