hpotter Posted November 9, 2010 Share Posted November 9, 2010 you're right, except there is nothing like a M & S deep discharge (low sexy voice), unless you want to reverse it. (no, dont mean high squeaky) Link to comment Share on other sites More sharing options...
arfur mo Posted November 9, 2010 Share Posted November 9, 2010 11 volts at battery? Best you check the battery output voltage with leads to battery disconnected, you should see ideally 13.65 volts (optimimum for many batteries). Reasonable DVM's don't round up to the extent you mention, it would be in the hundredths if not thousandths of a volt. Was the battery you fitted old stock? As They do discharge over a period if time. Arfur If you think education is difficult, try being stupid!!!! Link to comment Share on other sites More sharing options...

Rulland Posted November 9, 2010 Share Posted November 9, 2010 I reckon battery duff!-14v on charging circuit, output dropping to 11v when battery connected, and battery alone showing 6v-battery dragging it down imo. Mains fail you'll get probs with only 6v backup. Link to comment Share on other sites More sharing options...
mib150 Posted November 9, 2010 Author Share Posted November 9, 2010 Reakon charging is ok from that. As I was leaving the house, with the battery in my hand, the power light on the keypad went out. Further investigation lead me to find a loose connection in the mains supply circuit. (this explains the 'deep discharge' ) I've sorted this & replaced the battery, so hopefully everything should be OK now?? Sorry for being such an :*******: many thanks for all your help and advice. I'll let you know how things are in the next day or so. again Marcus Link to comment Share on other sites More sharing options...
