Can anyone tell me if this would be up to general DIY about the
house and garden.

probably, upto a point. I would want a mains power tool first though,
if youve not got one then forget the codless things. One of those and
nothing else wont get you that far.


Also, can someone explain to me what the 15.6 V and 1.2Ah battery
means.

Battery pack capacity is 15.6v x 1.2Ah =3D 18.7 watt hours. Not a lot!
Realise of course that when used in a power tool you wont get
anywhere
near the optimistic ideal conditions 18wh rating.


I see apparantly less powerful machines for treble the price at
Screwfix.

Volts is not power. They dont ever tell you the power output of these
things, cos if you knew you wouldnt buy them. Get mains unless you
need
the codless feature.

Lets explain just what this means, especially for our resident diyfaq
expert.

18wh under ideal conditions means with slow discharge, ignoring memory
effect, and batteries as good as new. So IRL lets say we get more like
10wh from our pack.

Now how long can we use such a tool for on one charge? I dont know, but
lets guesstimate 15 minutes of continuous run time. Thats 1/4 of an
hour, so during that time our 10wh is giving us an average of 40w.
Thats right, 40 watts. And thats for a 15v tool.

Something like this could be handy in the power tool faq.
