Original manufacturer or Amazon?

£80 against £35.

I’m leaning towards manufacturers as it’ll be on charge under the stairs. If it was plug in while I’m watching it I wouldn’t be so concerned.

I fitted an Amazon battery to a dyson. It's been fine. Original charger though.

I thought it was knockoff chargers that were the real problem.

Some 'battery packs' have quite a lot of charging electronics in them.

I have some ebay Li Ion batteries which I don't leave charging in the house unsupervised.

Personally I don`t take the risk and buy genuine for peace of mind.

OEM.

There will be multiple 18650 cells in the vac battery.

In the vid below Adam Savage (Myth Busters) teams up with some quality battery nerds to CT scan these batteries.

They find that the lack of quality control in the no-name cells means they rarely perform as advertised, whilst a surprisingly high percentage had internal faults which make them hazardous.

It's easy to virtue signal about buying genuine stuff, but the 'genuine' battery was probably a bit crap if it's failed already.
Paying over the odds to get the exact same piece of rubbish can be a flawed strategy.
More so if it's a 'spare part' that's been languishing in a warehouse for months.

Manufacturers of consumer goods might well be buying a lot of second-rate cells.
Whereas an aftermarket replacement might have anything from Panasonic cells downwards.

There are an awful lot of Lithium batteries out there and relatively few catch fire.
You're probably more likely to trip over the vacuum and break your neck than to be burned to death by its battery.
Which is to say, not very likely at all!

The other thing if it's a Dyson is you can get replacement adaptors without batteries, that allow you to plug in power tool batteries instead

Often, non OEM batteries are made up of old cells, cobbled togther into a recovered case and its totally hit or miss if you get any decent charge out of one.
Never had any real success myself with them.

This. If you've got dewalt/makita/milwaukee/whatever, the batteries are far better quality than the ste Dyson provide - so an adaptor makes it a better vac.
