Frequently Asked Questions

Does this rack work with all M18 battery sizes including high-output and XC packs?
Yes — the PACKOUT M18 Battery Rack is designed to store M18 batteries of any size, including standard, XC (Extended Capacity), and High Output packs. All M18 batteries share the same clip interface. Note that larger battery packs (XC5.0, HO6.0, HO12.0, etc.) are physically taller and wider, so confirm that four of your specific pack sizes fit within the 4" × 4" × 13" rack footprint before purchasing if you primarily run the largest format packs.

Does the PACKOUT Wall Plate need to be purchased separately?
Yes — PACKOUT Wall Plates are sold separately. The Battery Rack (48-22-8339) connects to and locks onto Wall Plates for wall-mounted storage, but the Wall Plates themselves are a separate purchase. If you are building out a wall storage system, plan for the appropriate number of Wall Plates for your layout alongside the Battery Rack.

Can this Battery Rack be stacked on top of other PACKOUT units without a Wall Plate?
Yes — in addition to mounting on Wall Plates, the Battery Rack slides onto PACKOUT tool box lids and connects with other PACKOUT components via the standard PACKOUT interface. It can be used as part of a freestanding stacked PACKOUT setup on a flat surface without wall mounting.

Are batteries charged while stored in this rack?
No — the PACKOUT M18 Battery Rack is a storage and organization accessory only. It does not charge batteries. To charge stored batteries, remove them from the rack and place them on a Milwaukee M18 charger separately. If you need charging-integrated storage, Milwaukee offers the PACKOUT Mounting Plate and charger combinations — those are separate products.
