Everyday power for household devices

This 12-pack of Black & Decker AA batteries supplies reliable energy for everyday electronics such as remote controls, clocks, toys and wireless peripherals. The lithium-ion chemistry delivers a stable voltage output and a long shelf life, making the cells a practical choice for homes, offices and workshops that want a ready reserve of standard-size power.

Replacing single-use alkaline cells

Switching to this lithium-ion pack reduces the waste and recurring cost of disposable alkaline AA batteries in high-drain devices. The upgrade is worth it when you regularly power gadgets that drain standard cells quickly, because the rechargeable chemistry maintains performance through many cycles and cuts the number of replacements needed over time.

Suits users with standard AA equipment

These batteries fit any device that takes a conventional AA cell, so they suit households, small businesses and hobbyists who want a single rechargeable format for multiple tools. They are not for equipment that requires proprietary battery packs, higher-voltage formats or specialised chemistries beyond the standard AA form factor.

Questions about this item

Which devices take the 12-pack of Black & Decker AA batteries?

They power the GLL50-20 laser, which runs on two AA cells or the optional 3.7 V 1.0 Ah lithium-ion pack.

How do I install the batteries in the GLL50-20 without triggering the pendulum lock?

Slide the battery cover off, insert two AA cells matching the polarity marks, then replace the cover before turning the unit on.

When should I replace the AA cells in the GLL50-20?

Swap them when the laser lines dim or the unit blinks to signal low power, typically after several hours of continuous use.
