Hi, some of you may have read I bought a new Varta E11 battery for my car in the depths of winter. It was frequently down to -30c here in Latvia and the new battery helped a great deal. (It still cranked for over 40 seconds before starting though, so you can see why I needed a new battetry).

My question is for any battery experts out there.

I have taken the Varta out of my car to store until next winter, as my older battery is more than capable of starting my car in the Spring/Summer/Autumn.

Should I fully charge the battery (I have an intelligent charger that is capable of supplying a float voltage) and store it disconnected until needed next Winter, or should I leave it connected to a float charge for all this time.

Many thanks.............ebt
