Black and Decker Genuine BL1554 54v Cordless Li-ion Battery 1.5ah

Battery AH Explained

The best way to describe battery amp hour is that this is effectively the size of your fuel tank, the more amp hours your battery has then the longer the battery will last between charges. More amp hours does not increase the power of a given tool.

Battery Voltage Explained

A tool with a higher voltage than another is a bit like choosing an engine in a car, the higher voltage will generally mean higher power & performance. As with cars though a bigger engine does not always translate to better performance so it is important to compare the specifications of tools at different voltages between different manufacturers.

Black & Decker Dualvolt

Black & Decker 54v Dualvolt is the new Black & Decker dual voltage system. A 54v Tool can only use 54v batteries, however your new Black & Decker 54v Dualvolt battery is fully compatible with all Black & Decker 18v Li-ion Power Tools as it is capable of stepping into 18v mode for this purpose. So upgrading to 54v means you can still make use of your 18v power tool range. 54v batteries are currently available in 4.5ah (18v mode) / 1.5ah (54v mode) & 7.5ah (18v mode) / 2.5ah (54v mode).

Customer Questions & Answers

Nick Everitt asked on 28/11/2021

Q : I have a B&D battery chainsaw with 2 lithium 2.0 AH 36v BL20362 batteries. Would those batteries be compatible with this hedge trimmer?

TooledUp answered on 29/11/2021

A : Hi Nick, you've asked this question about a battery so I'm not 100% sure which hedge trimmer you're referring to - however, your 36v batteries will only be compatible with Black & Decker 36v hedge trimmers, of which we stock two (see product codes 21032553 and 21003758). If you're considering the 54v Dualvolt hedge trimmer this can only be used with Black & Decker 54v Dualvolt batteries and won't work with 36v or 18v batteries.

Margaret Kesten asked on 10/09/2021

Q : Is this the replacement battery for Black and Decker strimmer STC5433PC? My existing battery is flashing a red light on charging which I assume means it is not charging. The strimmer is not working. Do I need a replacement battery?

TooledUp answered on 10/09/2021

A : Hi Margaret, I can confirm this is a suitable replacement battery for the Black and Decker STC5433PC. It's a bit hard to say with certainty that you need a new battery though as it could potentially be a problem with the charger for example.

WALLACE BROWN asked on 26/04/2021

Q : Is the charger included?

TooledUp answered on 26/04/2021

A : Hi Wallace, this is for a 1.5ah battery only but we do stock a compatible charger on product ID 21004465
