Litch90 Posted November 1, 2016 Share Posted November 1, 2016 I've had two 7AH batteries go flat in my panel within the space of a week. Checked voltage I get 13volt at battery terminals on PCB. Both batteries were a decent brand YUASA. I have set my panel up for fault override, but ideally I need to find a solution to my problem.. So it seems like the panel is somehow gutting brand new batteries is that not usually a faulty PCB? Whats your diagnosis? Thank you gents Quote Link to comment Share on other sites More sharing options...
james.wilson Posted November 1, 2016 Share Posted November 1, 2016 whats the charging voltage? Quote securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount. Link to comment Share on other sites More sharing options...
sixwheeledbeast Posted November 1, 2016 Share Posted November 1, 2016 Use your meter to check the battery is being charged, voltage on the leads isn't checking much. Quote Link to comment Share on other sites More sharing options...

Lets say its not being charged, there is no escaping it, its a new panel/transfromer is it? Quote Link to comment Share on other sites More sharing options...

sixwheeledbeast Posted November 1, 2016 Share Posted November 1, 2016 Yep if the charging rate is low unless you are capable of diagnosing the issue with the charging circuit. Most installers would replace and wouldn't get involved with component level stuff. If there's voltage then the battery fuse will be fine? ACT tester could be faulty, batteries could be a faulty batch, I would definitely be sure to test everything before replacing the panel. To the batteries charge and then pass on another panel? You have proven the battery and the tester then Quote Link to comment Share on other sites More sharing options...
