Battery Vent Plug

[Andy 308GTB]

Mr. Google got me nowhere.
New Yuasa battery, I'm convinced that the plug in the pictures should be removed. It came out very easily and is quite flimsy.
When I have had batteries with vent plugs previously there have been clear instructions that they should be removed but nothing in the accompanying document or on the Yuasa website. A recent Reddit thread had varying opinions but I suspect there was a bit of trolling going on, the trolls were insisting that it should be retained.
Whatever, I've removed it but I'm interested on what the forum thinks.
I'm now arguing with a well known online battery retailer about the failure of the 4 month old battery. No parasitic leak found following a (lengthy & not inexpensive) test by a good auto electrical company.

You are correct to remove it good old google says as below

plus I bought a new battery for my x type recently and was told remove red breather , the battery needs to breathe

Vent Plug RulesEngine Bay Location: If your Yuasa battery sits in an open engine bay, remove transit plugs from both sides (or ensure the built-in labyrinth/side vents are clear) so the battery breathes freely to the atmosphere

Boot or Cabin Location: If the battery is mounted inside the vehicle interior or boot, insert a blanking plug into one vent hole and connect your vehicle's flexible rubber extraction/breather pipe to the other vent hole.Never Seal Both Sides: Never leave red transit caps fully blocking an active vent side during use, as trapped hydrogen gas build up can cause the casing to rupture or explode.

Thanks.
I assumed, wrongly, that my Google search skills were OK...
I find it odd that that the battery didn't have something on it, that's my excuse & I am sticking to it!

Whenever i've bought from Tayna there's usually labels attached informing you to remove the plugs.

This is the replacement battery which came from my local motor factor - which was actually £5 cheaper than Tanya.

My 2005 Merc combined those - the battery was under the bonnet, but separated from the engine by sheet metalwork, so it was more like it was part of the scuttle area. There was a battery drain tube from one of the vents through the base of the compartment.

By coincidence I had a new battery delivered today and the external box and all the internal plastic was plastered with labels saying "Immediately remove the transit plugs" when unpacking.
