Fatty Posted January 8, 2017 Share Posted January 8, 2017 OK made a school boy error - ordered a new battery came dry and in my eagerness have filled two cells with distilled water. Have i ruined the battery or can i empty it and refill with battery acid? Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted January 8, 2017 Member Share Posted January 8, 2017 I'd give it a go. But if I did I'd swill the relevant cells with the final fluid and empty again before filling. As always a few small swills is more effective than one big swill of the same total volume.Usual precautions with the acid: this is going to be messier than the average fill.Jonathan Link to comment Share on other sites More sharing options...
Roadsport06 Posted January 8, 2017 Share Posted January 8, 2017 No damage. Water out, acid in. Link to comment Share on other sites More sharing options...
TomB Posted January 9, 2017 Share Posted January 9, 2017 General Banner question - I picked the latest thread... I have an old/ spare wet acid Banner sat on the garage worktop for a couple of year, kept as a backup or for jump starting. It now wont take charge and reads 7-8 volts. Is it scrap?

Member Jonathan Kay Posted January 9, 2017 Member Share Posted January 9, 2017 It now wont take charge and reads 7-8 volts. Is it scrap?Probably. If the cells are topped up and immediately after trying to charge that's what it reads with no load then it's pining for the fjords. NB safe disposal.Jonathan Link to comment Share on other sites More sharing options...
TomB Posted January 9, 2017 Share Posted January 9, 2017 Ill have a look at the cells tonight, otherwise Ill set fire to it on the patio Link to comment Share on other sites More sharing options...
Roger Ford Posted January 9, 2017 Share Posted January 9, 2017 It's likely the plates are sulphated.You could try some Bat-aid pills (they're not the snake oil they might sound like) and then charge with an intelligent charger which has an anti-sulphation setting.Probably won't work, but for £4 (assuming you have or can borrow an appropriate charger) it's worth a try.
