Frequently Asked by Distributors:
Does the WK18-XC60 replace the Milwaukee 48-11-1860 6.0Ah battery?
Yes, the WK18-XC60 is a direct replacement for the Milwaukee 48-11-1860 M18 RedLithium 6.0 battery. It is a true 6.0Ah 18V pack that fits and works with the Milwaukee charger.
What is the MOQ for the WK18-XC60 replacement battery?
The standard MOQ for the WK18-XC60 is 100 units. You can get paid samples of 1–10 units to check the BMS-handshake before placing an order. Private-label or custom-spec runs start at 500 units.
Is the WK18-XC60 drop-in compatible with original Milwaukee M18 chargers?
Yes. The WK18-XC60 BMS has M18-specific software, so it works correctly with Milwaukee chargers. It also has the same fuel-gauge reporting, authentication, and safety lockouts as the OEM RedLithium pack. Handshake is validated on 100% of units at the end of the line.
Are these Milwaukee M18 replacement batteries any good?
Yes. Our WK18-XC60 uses high-quality cells from leading brands like Samsung, LG, Panasonic, and BAK. These cells are matched in capacity and resistance, and their performance is validated by a battery management system (BMS) for compatibility with genuine Milwaukee chargers. This validation is performed on 100% of the units. It is made as a professional-grade Milwaukee M18 replacement battery, not a low-cost copy, and is backed by a 12-month warranty.
Will Milwaukee or Home Depot replace my battery — and how is your WK18-XC60 different?
Milwaukee’s warranty covers genuine packs through their service channels. We are an independent factory that supplies new WK18-XC60 replacement packs for the M18 platform. These packs are a direct, lower-cost alternative when a pack is out of warranty or you need a large supply. They have full UN38.3 / IEC 62133 / CE documentation.
Do you replace the cells in my old Milwaukee battery?
We supply complete, ready-to-use WK18-XC60 replacement packs — we don’t offer cell replacement or rebuild services. A new pack with fresh Grade-A cells and a fresh BMS is far more reliable than replacing the cells in an old M18 battery, and it comes with full safety documents.
How do I install the WK18-XC60 M18 replacement battery?
It installs just like a real Milwaukee M18 pack. All you have to do is slide it onto the tool until it latches, and then charge it on any real Milwaukee M18 charger. You don’t need to change it or buy an adapter.
What cells and configuration does the WK18-XC60 use?
The WK18-XC60 uses high-quality 18650 cells (3000mAh each) arranged in a 5S2P configuration for a nominal 18V and a true rated capacity of 6.0Ah. Before assembly, cells are matched based on their capacity (±20 mAh) and internal resistance (±5 mΩ). You can specify your preferred cell brand (Samsung, LG, Panasonic, or BAK) when you place your order.
What is the warranty on the WK18-XC60?
All WK18-XC60 replacement packs come with a 12-month warranty that covers manufacturing defects. Every batch of products is shipped with the following documents:
– UN38.3 test report
– IEC 62133 certificate
– MSDS
– CE Declaration of Conformity
These documents are needed to clear customs worldwide.
