Black & Decker Weed Eater Battery Charger: Charging and Battery Help

Match the charger to the battery platform first. A red flashing indicator can mean different things across BLACK+DECKER charger models, so use the tool and battery manual before deciding what to replace.

A BLACK+DECKER weed eater battery charger must match the voltage and battery family printed on your trimmer's battery. BLACK+DECKER sells cordless trimmers in different platforms, including 20V MAX models such as the LST300; chargers that look similar are not automatically interchangeable. Check the model number on both the tool and battery before ordering a replacement.

Common questions

Questions before you buy

How do I start a BLACK+DECKER battery weed eater?

Install a charged compatible battery until it locks in place, then follow the model's manual for its lock-off and trigger sequence. Keep the guard fitted and clear grass from the head only after removing the battery.

What does a blinking red light on a BLACK+DECKER weed eater battery charger mean?

It depends on the charger. BLACK+DECKER support says rapid red flashing on some chargers can indicate a weak or damaged battery; alternating fast and slow flashes can indicate a battery that is too hot or cold. Check the exact charger's manual before acting.

Can I use a 20V battery on a BLACK+DECKER 18V weed eater?

Do not assume they are interchangeable based only on the label. Check the tool model, battery family and approved accessories in its manual; BLACK+DECKER describes the LST300 as a 20V MAX trimmer, for example.

Why will my BLACK+DECKER weed eater battery not charge?

First confirm the outlet works and the battery is fully seated. If it is warm after use, BLACK+DECKER advises allowing it to cool before trying again; persistent fault indications should be checked against the charger manual or by an authorized service centre.

How do I find the right BLACK+DECKER 20V battery charger?

Use the model number on your battery and trimmer to identify the compatible charger in the official manual or BLACK+DECKER parts and accessories listings. Avoid choosing by connector shape alone.

Can a rapid flashing red light mean the charger is faulty?

It can take testing to distinguish a battery fault from a charger fault. BLACK+DECKER recommends comparing with a compatible battery where the manual permits and contacting an authorized service centre if the indicator persists.
