Will this fit my Black+Decker 20V MAX drill?

It is made to replace the LBXR20 and fits Black+Decker 20V MAX tools and chargers that take that pack, including the LDX120 drill and LCS120 saw. It does not fit 12V, 18V or 40V tools.

How does 4.0Ah compare with the battery that came with my tool?

Most Black+Decker 20V kits ship with a 1.5Ah pack. At 4.0Ah this one holds more charge and runs longer per charge, but it is heavier in the tool.

Do I need to charge it before first use?

Yes. The maker says the pack must be fully charged before its first use.

Is this a genuine Black+Decker battery?

No. It is a third-party replacement that cross-references the LBXR20, LB20, LBX20 and LCS20 part numbers. It carries its own one-year warranty rather than Black+Decker's.

Two 20V 4.0Ah LBXR20 replacement batteries and a user manual.

Does it have a memory effect?

No. The pack is lithium-ion with no memory effect, so partial charges between jobs are fine.

Our take on the Black+Decker 20V MAX LB20 Replacement Battery

This is a third-party lithium-ion replacement for Black+Decker's 20V MAX LBXR20 battery, rated at 20V and 4.0Ah. It is sold as a two-pack with a user manual and is built to fit the same tools and chargers as the original pack, including drills, trimmers, blowers and string trimmers in the 20V MAX line. The 4.0Ah capacity is larger than the common 1.5Ah packs that ship with many kits, so runtime per charge is longer, though the pack is heavier. It is a value alternative to the genuine LBXR20 rather than an official Black+Decker part, so buyers trade the brand name and OEM warranty for a lower-cost two-pack.
