Our take on the WMEXINBAO 20V 5Ah Lithium-Ion Replacement Battery Pack for Bauer 20V Cordless Power Tools, Replacement Battery

This is a third-party 20V lithium-ion battery pack built to replace Bauer 20V batteries in Bauer cordless tools and chargers. It carries a 5.1Ah capacity, roughly 70% more runtime than Bauer's 3Ah packs, plus a press-to-check fuel gauge and a nylon case with a rubber-covered base instead of plain ABS. It suits Bauer owners who want longer runtime and a spare pack without buying the brand's own batteries. The trade-off is compatibility: it fits Bauer 20V tools and chargers only, and it is not a Bauer-branded pack, so warranty and cell quality are the unknowns against the original.

Questions and answers

Which tools and chargers does this battery fit?
It is made for Bauer 20V cordless tools and Bauer 20V chargers, including the 1704C-B and 1906C-B. It does not fit other brands.
How does 5.1Ah compare with Bauer's 3Ah pack?
The higher capacity means longer runtime per charge than a 3Ah pack. Expect roughly 70% more run time at the same draw, though actual results depend on the tool and load.
Does it have a charge indicator?
Yes. A fuel gauge lights up when you press it, so you can check remaining charge without putting the pack in a tool.
Is this a genuine Bauer battery?
No. It is a WMEXINBAO replacement pack (model BAU5AX) made to fit Bauer 20V tools, not a battery sold by Bauer.
What is the case made of?
The pack uses a nylon case with a rubber-covered base rather than plain ABS plastic, which adds grip and some drop protection.
