Help please looking at buying  a MkIII and when looking under the bonnet it’s a bare battery. Can’t find a specific photo on-line so I thought I could ask the experts here.  I’m assuming it’s similar to my MkII with a clip off lid. 
thanks in advance. 

My 2015 MkIII VRS battery was completely enclosed. My 2018 Golf has a cover around the sides and nothing on the top. 

Just looks like a folded paper box in mine. The lid is hinged on one side. 

Thanks, I’m sure it should have one so I’ll not be happy until it has. Main dealer so if not in stock can be donated from another car. 

Hi all.

 

Having some battery issues and noticed that my 2019 Octavia VRs doesn't have a cover on the battery box. I've owned the car from new but never noticed. It has been serviced once by Skoda but I wouldn't think taking the battery box lid off would berequired as part of a service ? 

 

The battery is in a battery height tray with padding inside. But open at the top.

 

Should the battery box have a lid ?

On both my previous 2015 1.4TSi and my current 2016 1.8TSI the battery was/is wrapped in a fabric box that included a lid, but you seem to be describing something much more rigid than that?

 

Maybe something more rigid was a facelift change?

My 2019 1.6 TDI does not have a lid, just a "fabric sleeve". Seem to remember the sleeve is some sort of heat insulator, but I may be wrong.

You don't need any protection there. The factory cover is a sleeve. 

 

There is an aftermarket top cover if you want your battery to look fancy even though only the mechanic will be impressed

Nice and cheap. 

You may well find that the battery tray has all the retaining lugs for the proper plastic battery case and lid as fitted to earlier models like the MK2 Octavia.

 

I took a punt on a really cheap one from Ali-Express and with a bit of persuasion it fitted perfectly on the Yeti.

 

I know it does not need a cover but once you have had a decent one like the MK2 then the underbonnet area on the Yeti looked naked with the soppy felt thing which looked like Alexis Sale after I had fitted a bigger 096 battery!

Pretty sure I've seen mk5/mk6 Golf plastic battery boxes fitting into the existing Octavia battery trays but can't find any links now. I don't think it's hard, and a second hand battery box from a breaker should do the job. From memory the battery tray is the same, it's probably a way of cost cutting by not fitting a plastic case. In colder weather the slightly insulated case would do more than a plastic box to keep the battery warmer though.

Just in case people ever wonder, the function of the fabric cover is not to keep battery warm in Winter, it's to keep out the heat from the engine bay destroying the battery.

 

It's a common misconception.

VAG have made this statement, I can dig out the source if needed.

 

Choice between a plastic box and the fabric cover, the one @roottoothas linked to is what you need, more so if AGM battery is used.
