Jason Rees, 03/06/2022

Last for ages

tim woods, 02/06/2022

Amazing battery. Run time on it is amazing meaning I only need one battery to run all my tools. So far has ran my chainsaw for almost two hours with a single charge and still on three lights. Definitely recommend if you’re liking for something to keep you going through a days work and more.


Brilliant battery for my dewalt mixer

mr s barber, 26/05/2022

With a grinder and skillsaw it works all day with great power

Mr Dominic Guigan, 01/05/2022

Expensive, Large battery 54v 9ah for blower.

Stephen, 16/01/2022

This is my best battery. Often in my work, I must cut by jigsaw and am not disappointed when I have to work all day with one battery including changing the battery to another tool

Marek, 04/01/2022

Very expensive item but the service from FFX was excellent and I paid the lowest price online.

Tom Betts, 01/01/2022

Great lasting battery

Does what it says on the tin 👍

Sean morris, 04/03/2021

Needed 4 of these batteries for my Dewalt Mitre saw and they're just brilliant.

Martin Turner, 03/03/2021

It's big, heavy and powerful. Only 3ah at 54v, but 9ah at 18V. There is an improvement in power delivery at 18V

MemeZilla, 03/03/2021

its a battery

David Eastlake, 25/02/2021

Heavy but full of electric power. Enough for hours of drilling, chiseling, and several minutes of grinding.

Anthony Calder, 25/02/2021

Well built

stewart , 25/02/2021

Very good product

Razvan Stelian Timofte, 16/02/2021

Doesn't last no where near as long as my old battery

Ryan mercer, 16/02/2021

Ok batteries I suppose, was expecting much better run time from them to be honest.. I’m running on the new Dewalt 250mm battery mitre saw and I’m getting just under a days work out of one fully charged battery, it does all depend on what you’re cutting and the sharpness of the blade in all fairness, those two factors play heavily upon its performance. I’d like to see how the 12 amp stacks up against these, not willing to pay the price tag currently though. Over all they’re pretty good batteries, and the price I paid for them both on FFX was very reasonable.

Jim, 14/02/2021

Excellent so far no problems at all. Second one ive bought. Great price, great battery and quick delivery from someone you can trust.

RICHARD JAMES, 28/01/2021

Good battery I use it on my chop saw for first fixing and it lasts two days only thing is that it takes ages to charge but they can’t help that it is what it is

Dean stevenson, 27/01/2021

Brilliant battery, a bit heavy for use in smaller tools

Alex , 31/12/2020

Monster of a battery, seems to last forever in a 18V XR tool.

Dean Whitbread , 24/12/2020

Not to mention it is powerful battery. The only reason I gave 4stars is because it is little bulky. Actually I was under the impression that it will be the same size as the 6Ah, however, I am using it with my jigsaw, so infect it is ok. I believe I was lucky enough to get it at a very discounted prise from FFX. I definitely would recommend.

Harry Gohil, 24/12/2020

Great battery's and got for a great price off super supplier will be buying again

Diarmaid Keane, 24/12/2020

A little bigger than I was expecting but lasts forever

customer, 24/12/2020

Arrived very quickly. A good price compared with other suppliers.

Gillian Jeffries, 24/12/2020

Not used it yet, just charged it up, hope it last longer than my 6amp battery that was a dissapointment hardly used

Paul Phillips, 19/08/2020

Great battery worth the money

KEVIN MITCHELL, 06/12/2019

Good tools

Gediminas, 16/07/2019

Terry Draper, 12/04/2019

Very good

simon riddell, 05/04/2019

It's a flexible beast with 18&54v available from one battery. Only downside is weight.

Kevin B, 29/06/2018

bigger in size than 6 ah and took a bit longer to charge but runs the table saw great

peter miller, 29/06/2018

I am happy to buy from FFX.

Leonid Zdragon, 09/02/2018

Over priced and temperamental,

James Thompson, 05/01/2018
