New Car Battery Storage

[neilbardsley]

By the wonder of the www I received two 6v batteries for my 356. I tried to contact the seller but didn't get a reply and didn't follow up quick enough because of holidays etc. Anyway now I have 2 batteries which I will not use until our next trip April/May 26. They are in the packaging and air sealed. I'm attempted to leave them that way rather then taking out of the packaging and charging. I don't have enough tickle charges to keep them both topped up. I think this is perhaps the best approach as they will sit in the warehouse like that? May only doubt is to move them out of the garage as the temperature can drop during the winter?

They don't like cold, no. Keep them in the house.

Do they have vent plugs?
Usually the packing states very clearly they MUST be removed asap, at least all my batteries over the last years state this.

I too gained a spare new 12V Bosch battery, not needed (yet) so in my garage along side the 2 x 911 Bosch batteries and two others.
All disconnected after a full charge first.

I leave then alone for a month or so and charge them again, but that does not take long, very little discharge.

For many years the batteries are good in the spring after 6 months out of the cars; charge as required (very little) and refit, fire up the old 911.

When it get cold the new 12v will come inside, the rest will rest in the attached to the house garage where the boiler is, so always 'warm' compared to outside ambient.

I don't think they have vent plugs. I can't find them

On my recent 12v units, the breather is red and about 2 mm dia.
Could be the battery type does not need a vent?
