walshie Posted August 16, 2020 Report Share Posted August 16, 2020 Is it safe to charge a boat battery in situ without disconnecting it as long as I turn off the battery isolator? Quote Link to comment Share on other sites More sharing options...
Capt Christopher Jones Posted August 16, 2020 Report Share Posted August 16, 2020 (edited) Mine are only on charge when i am onboard, i never ever leave a charger on 24/7, there is always a risk of charger failure, resulting in cooked batteries, i have 3 domestic & 1 engine battery. But yes to your original question Edited August 16, 2020 by Capt Christopher Jones Quote Link to comment Share on other sites More sharing options...

But yes to your original question Cheers. No I'm not going to leave a charger on. I just thought I;d top it up while it's here. Quote Link to comment Share on other sites More sharing options...

walshie Posted August 16, 2020 Author Report Share Posted August 16, 2020 (edited) I just bought a leisure battery (not for the boat) from Advanced Battery Supplies. Very competitive prices. Edited August 16, 2020 by walshie Quote Link to comment Share on other sites More sharing options...
ph5172 Posted August 16, 2020 Report Share Posted August 16, 2020 I know a lot of people do it. some with sensitive electronic equipment prefer to disconnect. I have some quick disconnect battery clamps. I do have a battery charger that has a quick couple connector. Comes with a set of clamps and a set of o ring attachments. Put the o rings in the nut and bolt on the clamp and run the cable to an accessible place. Saves having to contort yourself in all manner of positions. it was £30 on amazon and performs similarly to a ctek Quote Link to comment Share on other sites More sharing options...
