Talking to 'the battery man' this morning, he has revived batteries that are down to 0.3 volts.

The circumstances of the discharge are relevant though.

The temperature conditions the battery has been kept in and the rate of discharge.

A rapidly discharged battery will have sulphated less and has a better chance of giving a fuller capacity when revived.

Batteries do not like the cold when discharged fully.

Also the overall age of the battery is significant when trying to recharge it.

The normal Optimate will not pull up a fully discharged battery and it will continue to dicharge itself due to its internal resistance which rises the further it discharges.

(Sorry, probably boring info)
