No problem, seriously. But, if you look at the first pictorial of the instructions, it's telling you to remove/pull the plug (arrow away from battery) to vent it to prevent explosive/corrosive gasses from building up and cause external damage or even damage to the battery itself.

Just wait for Varta to confirm or provide clearer guidance and post an update. Here is a Google search on the topic:

If the battery didn’t have the stickers I’m wondering if it’s been out to someone before ? I would get pliers and remove that white plug it also looks like someone has had a go at it before.

My new Varta F21 AGM battery arrived today. I looked to remove the vent plugs used for transit purposes, but only found this



The other side is identical.

Attached to the positive terminal cover was a plug that fits in the hole perfectly




The pictorial instructions are worthless




So after an hour of trawling the good old tinterweb, I convinced myself that the battery did not require venting, and had an inbuilt safety vent system. I found reference to sealed vent holes in the Varta site, but unfortunately fig. 1 ( the image ) was missing !

So I put it on charge with my Ctek charger set to AGM mode. However, after checking the battery after an hour, the charger was at stage 4, I noticed that the side walls were " rounded"




So I took it off charge. I did not notice if the sidewalls were flat when it came out of the box

Can anyone who has fitted one of these batteries confirm if one of the flush fitting plugs / holes should be removed, or is this battery sealed and doesn't require venting?

I have looked at the original land Rover battery on the car ( also Varta AGM ), which has a vent pipe fitted, but upon close inspection, the hole in to which it is plugged, appears to be a blind hole.

How hard can it be to replace a car battery? I did the glow plugs and swirl flap removal yesterday which was easier than this!

As always, any help and advice will be greatly appreciated......

What you have done is not quite correct! The blanking plug should be next to the - terminal. The 90° vent fitting then goes in the opposite end, usually next to the + terminal.

The Yuasa AGM I fitted recently definitely had transit plugs fitted which I removed and connected one vent hole to the vent pipe as per instructions (your instructions seem the same to me) 2014 Freelander 2 TD4 Manual Dynamic
1956/7 88" Series One Land Rover
1956/7 88" Series One Land Rover - undergoing restoration

The vent pipe on the car is a perfect fit, as is the plug shown in image 2, but definitely no transit plugs ........ so .......

I removed the old Land Rover (varta) battery and stood it on its end, result, no leak from vent hole. Repeated process with a spare lead acid battery, same result, no leak.

After careful examination, and with the aid of a thin long screw, I probed the unblanked end where the vent pipe fitted in the old battery ...... and found a tiny hole at the bottom of the "blind" hole, same result with the new battery.




The negative terminal end of the old battery was plugged




I also noticed that both end panels of the old battery were concave, as opposed to convex on my new battery.

My conclusion is that yes, both batteries are vented, my new battery was shipped without transit plugs which should have been fitted, and the rounding ( convex ) nature of the end panels on the new battery was not caused by the battery not being vented whilst on charge with the ctek.

I shall continue to chase the supplier to find out what has gone on, but am not holding my breath as a German supplier shipped the battery to me in France, and I am English !

The new battery is fitted, vent at + end, plug at - end and car updated with SDD. I have just given it a run and all seems well.

What a performance for a couple of missing transit plugs! Will update should I get any sense from the supplier. Again, thanks to all who have contributed

Sounds about right to me
