Aldi's batteries for their power tools

[freddiemercurystwin]

Because they lied to me saying you can buy from another store or online.
So should I return or weight until next batch?

They do stock them in other branches and if not now they surely will soon, so why don't you just return it then?

The ebay one is almost double the aldi price, but still cheaper than dewalt. get one so you can start using it then buy one or two more from aldi when they are in stock. I was lucky to get the brushless angle grinder, has pretty good battery life when cutting sandstone for the patio.

Might find one on your local Facebook Marketplace, or find one with another tool attached!

May not be a lie, plenty of them on eBay:

what is the brushless; dose it not clog up with dust and not die on you?

The brushless gives a slighter longer runtime with the same battery as the electrical losses are smaller.

I live close to an Aldi in South Gloucestershire and they do have 20/40V batteries in stock at the moment. To prevent theft, you pick up the box within the store, and they give you the battery at the checkout. You will need the 20/40V version for your angle grinder.

Do you understand what a motor with brushes actually is?
They are not little hairy things that sweep the dust away.

Me thinks someone needs to do research, before spending money..

Plenty of articles on that one

Looks like aldi cant be bothered any more with the click and collect thing

They are carbon magnetic blocks as far as I know of. That everyone says "ohh it the brushes! its the brushes!" when infact it is something ells!

right so it a motor with out any brushes to burn out. not that they burn out in there lifetime span of cource

No, they are noy magnetic as they are made from carbon. Carbon is a good conductor of electricity, and they are used in electric motors to make the connection to the armature, (the bit that spins round and is attached, via a gearbox, to the chuck of your drill. They are called brushes simply because they 'brush' against the armatures commutator.

As above, carbon has a higher resistance than the mosfets used to switch the power, also, by design brushes need to span the gap between poles and that causes a bit of shorting/braking current to flow for a bit of each cycle. Done right the efficiency is awesome in a brushless converter.
