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.

Bought just over a year ago, light DIY use and already defective. Other brands I use, such as MAKITA, much more reliable. This is also quite an expensive battery!

Customer Questions & Answers

John Drew asked on 19/04/2022

Q : Is this battery compatible with the Black and Decker BCMW3318 36v Cordless Rotary Lawnmower 330mm (Uses 2 x 18v)? Presumably I will need 2. Does this battery then give me twice the usage or duration of the 2ah variant ? Thanks .. John

TooledUp answered on 19/05/2022

A : Hi John, this battery is suitable for the BCMW3318 yes (as long as you use two of them) - you are correct in that it should give you around twice the runtime you'd get with a 2ah battery

Alex asked on 23/05/2021

Q : Is this battery compatible with the Black & Decker orbital sander BDCROS18? I currently use an 18V 1.5ah battery for it but wanted a longer lasting one instead.

TooledUp answered on 24/05/2021

A : Hi Alex, it will work with it yes - with the larger batteries you might find it a bit more awkward to use, potentially, although Black & Decker don't mention any that are too big for it

DAVE JOHN asked on 09/05/2021

Q : is this battery compatible with the black+decker 18V 4in1 cordless POWERSERIES extreme vacuum cleaner?

TooledUp answered on 10/05/2021

A : Hi Dave, assuming you mean the BHFEV182 that we stock on product ID 21032557, yes that vacuum cleaner can run on this battery

Steve asked on 29/03/2021

Q : Can the BL4018 18v battery be a direct replacement for the A18E H1 18v battery?

TooledUp answered on 29/03/2021

A : No I'm afraid the A18E H1 is an older NiCAD design and the current generation of lithium ion batteries are not interchangeable with these older types of battery

Frank Hannaway asked on 10/02/2021

Q : is this compatible with the Black and Decker BCD 700S cordless drill ?

TooledUp answered on 10/02/2021

A : Hi Frank, yes - this 4ah battery is suitable for the Black & Decker BCD700S

Hanafi asked on 02/05/2020

Q : Is this battery compatible with Grass Trimmer STC1820EPCF?

TooledUp answered on 04/05/2020

A : Hi Hanafi, yes this battery is suitable for the Black & Decker STC1820EPCF Grass Trimmer

James Gough asked on 01/04/2020

Q : Will this battery fit a hedge trimmer BTC 610

TooledUp answered on 01/04/2020

A : Hi James, I can't find any record of a Black & Decker hedge trimmer with that part code? If you meant the GTC 610 I'm afraid it is not compatible as that machine uses the older NiCAD batteries (which are no longer manufactured since the switch to lithium ion)

L asked on 01/03/2020

Q : Is this battery compatible with the older 18V HP188F4L Black and Decker cordless drill?

TooledUp answered on 02/03/2020

A : By the looks of it although the HP188F4L uses a lithium ion battery it is a slightly different design to the current range so I would assume the the tool and charger are not compatible with this battery I'm afraid

Jose asked on 22/07/2018

Q : Is this allowed on commercial airplane flight as a check in or carry on item?

TooledUp answered on 24/07/2018

A : I can confirm that you would need to check with your airline on their policy on carrying Li-ion batteries. they will be able to advise you on the maximum Wh rating per battery. This should be written on the battery or alternatively to determine the Wh you would need to times the Ah by the Voltage. For this battery Ah= 4 Voltage = 18. 4(Ah) X 18(V) = 72 Wh.

Christopher asked on 12/06/2018

Q : Is this compatible with the Black & Decker Cordless 25cm Strimmer, as i bought this with a 18v Cordless Li-ion Battery 1.5ah - ST1823

TooledUp answered on 14/06/2018

A : I can confirm that the BL4018 is compatible with the ST1823-GB strimmer which would have been supplied with a BL1518 battery.
