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

 

[big-all]

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

 

[ericmark]

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?}

Edit: English language manual for the bare tool is

We recommend that you operate this appliance with the following batteries only:
PAP 20 B1, PAP 20 B3, Smart PAPS 204 A1, Smart PAPS 208 A1, Smart PAPS 2012 A1

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.

 

[ericmark]

The Lidi grinder I am talking about, can use 2 Ah, 4 Ah, and 8 Ah batteries. The 2 and 4 Ah around the same size, improved technology. Also smart method to see how charged, god knows why. I am sure no problem with the 8 Ah version of the battery.

they only use ultra thin kerf sub 1mm i think maximum depth off cut is i think around 12mm or it may be 15mm on a new disc
and whilst you can cut wood via a special blade supplied i would not think it would do well on routing out and pointing both from the lack off depth and probably getting bogged down

Lidl have started tucking the batteries away, in the back room, they were suffering thefts. You have to ask for them, and hope they have them.

Cheers. The one I was thinking of is the 76mm Metabo

Depth of cut is up to 19mm which would be fine but total cost of ownership increases massively if I need to drop another couple of hundred quid on more batteries because of the short run time.

That's an expensive grinder, is it gold-plated? I keep finding the odd job when I need a grinder, but not enough to pay out that much, I do need to get a selection of discs, and one needs to look at the guard as to what discs will fit.

@Rodders53 has given me the link, so now have the manual, thank-you. And it says

We recommend that you operate this appliance with the following batteries only: PAP 20 B1, PAP 20 B3, Smart PAPS 204 A1, Smart PAPS 208 A1, Smart PAPS 2012 A1

I have not checked what my batteries are, but that list includes some 2 Ah versions, so it should work OK.

I look at the 20 pages of English instructions, and it tells me not to change the plug, it's battery powered, and the charger is not included with the grinder, I know I have attended courses to show me how to change wheels etc, and I realised for DIY use, the user may not have attended these courses, but to include things which have nothing to do with the product sold, means people give up reading the instructions.

I have looked for motor power, and can't find it, I suppose like RR where they never published power, top speed etc, it just said ample. This is the problem, we have to suck it and see. I started with a battery charger, wife thought it was for charging a car, so when I saw the 4 in 1 garden tool, I thought that was a good idea, easier to use compared to the Aldi petrol version I have, so I wanted a plunge tool, and now having already got 4 batteries and the twin battery charger, went for the Lidi multi-tool using same batteries. And then wanted an SDS drill, so again went for Lidi, as same batteries, so when I wanted a grinder, it seemed Lidi was the best option so did not need to buy battery and charger.

One gets locked into the system with the interchangeable batteries. But up to now all have worked well enough, the plunge tool was a little disappointing, but it does work, I looked at the Metabo

and I simply could not have afforded to buy into their system.

I have three, maybe four, angle grinders, all mains powered. I've almost never found a use for a battery version, as most of their use is in my workshop, with power close at hand. The odd time I have needed to use them more remotely, is when I have run an extension out anyway, for running other things like a breaker.

Too'ing and frowing, to charge batteries, can soon eat into time, versus simply plugging in an extension.

Battery drills, I have three types, and do find them worthwhile for quick jobs.

 

[ericmark]

I did wonder if the way to go is an inverter generator. At 3 kW it would run all garden tools, the largest is the leaf blower at 3 kW. I have also looked at other battery systems, these

do look tempting, but it is still battery powered, and you have leads to contend with.
