Battery size for angle grinder IAN 485600_2501 Parkside (Lidi)

[ericmark]

Not official been given it yet, it will be my birthday present. So not got the instructions out of the box. So did a google, Instructions in loads of languages except English I have 4 x 2 Ah 20 volt batteries, I wonder if this grinder needs the 4 Ah version.

Do I need the larger batteries?

i have the Dewalt angle grinder and use a 5Ah on that , doesnt last long ,, i havent really tried my 2Ah on - or if i did it didnt work very well
I cut a load of coach bolts on a fence and i think i got 10min run time cutting about 16 bolts

if you think off it a a 4ahx18v battery contains 72wh [72x60 4320wm] so iff your angle grinder is say 300w on full blast you have about 12mins on a full battery

Seems I need a trip to Lidi and get some new batteries then. Also need some discs, as it seems it only comes with a metal cutting disc. Can't use it for long anyway, I have a problem with my hand and tools which vibrate. Pity as I have 4 x 2 Ah batteries, the 4 in 1 garden tool uses two at a time.

as an aside

i have the little bosch blue 10.8 v mini grinder and i lent it to my electrician friend with a selection off 1.3/ 1.5/2.5ah batteries
and he said all the batteries weren't fully charge and couldn't comprehend that a brushless mini grinder off perhaps around 100w will only last perhaps 5 mins on a 1.3 [842wm]and about 10 on a 2.5 [1620wm] after transmission losses and battery degradation

Suck it and see when you get it. One 2Ah in use, two ready to use and the fourth on charge should mean that it's a simple rotation scheme... (How long to recharge from flat? 45 minutes?)

Then if bigger 4Ah would be useful (and heavier to use it!) then go buy. {They may be available mail order even if not in stores at the time?}

Two can be charged together, so when doing the gardening two in use, swap after around ½ hour, then second two, then need a ½ hour break before continuing, and I need a break by then.

Hmnnn, I was thinking of a small cordless angle grinder for cutting cracks in external render. I might have to consider a corded version (if they exist). I only need a 15mm(ish) depth of cut. I had thought that a smaller cutter would be easier to use on a ladder.
