I haven't been using the Omega much as I'm out of work at present, so the battery gets run down. It went all the way in the cold spell and so I stuck it on my (Oxford) (http://www.oxprod.com/index.php?pg=3&action=dept&id=134&pid=197&p=) charger that is supposedly clever. Well, it registered 3.1 volts and clearly decided it was not a battery so it would not touch it! I had to thump and cajole my 'traditional' (30-year-old) charger back into life just to get anything into the battery. Even then the current crawled up from 0.75 amp to 3.5 over about 5 minutes. Current has now steadily declined to 1 amp over 24hours so I suspect it is back to normal.
Just to see what the Oxford thinks now, I've put it back on that. It seems to be idling at 13 volts which is good.
BTW this is a VX battery with the green indicator built-in but now shows green even though it's 7 years old.
I'm glad I didn't trust the new-fangled thing and throw out the battery. :)

Just got an analysis back from the Oxford charger. It divides into 'Weak' and 'Strong' and has gone for the latter!
I think I might email Oxford Products.

Some "smart" chargers rely on the residual voltage to start their controlled cycles, and are not too good on really "flat" batteries.... or so I now believe....
I have a CTEK charger that I rate highly, but found when trying to sort someone else's problems that the CTEK would not start to charge. Put an "old fashioned" charger on for an hour then retried the CTEK and it started to work as originally expected.
Asked around and several other "smart" charger users said the same ..
HTH

may sound stupid, but if you wont use it for some time in cold weather its better to keep the battery at home ;D :y
