Ferrex 40V angle grinder Q?

[Mike13]

Is the Ferrex 40v Angle grinder asood as the other Ferrex Active enegy stuff? Opinions invited.
The others in the range seem capable, and I have a couple of 40V 2.5ah batteries already.
How longdoes it last on a charge etc?

if your tool has a watts rating then its a sum
2.5ax40vx60 mins = 6000wm so if its say 500w it will last up to 12 mins on full load
24 mins on half load and around an hour on 20% load

but remember you can knock off perhaps 10-20% for losses and a bit more for every year youve had the battery

the blurb available online from aldi does not state the power, so no idea how long it will run on one battery
