Rich Posted November 26, 2013 Report Share Posted November 26, 2013 I can't really be bothered to take the battery out and charge it overnight but could I use my charger with the battery still in the car? Do I need to disconnect the terminals when I use it? I was thinking of putting it on tonight or in the morning for an hour or so to give it a boost before trying to start it. This is the type of charger I have and it can fast or trickle charge - http://www.argos.co.uk/static/Product/partNumber/7404355.htm Quote Link to comment Share on other sites More sharing options...
SMARTLY Posted November 26, 2013 Report Share Posted November 26, 2013 On their Q&A: There is no need to take the battery off the car but you must remove the two terminal wires (Red & Black) so you don't damage the alternater by pushing the current backwards. As always take care in not getting the unit wet when using outdoors as the risk of electric shock. Quote Link to comment Share on other sites More sharing options...
Rich Posted November 26, 2013 Author Report Share Posted November 26, 2013 Doh didn't read those! I'll put it on tonight and see what charge is left in the battery. I just don't what to spend time in the morning fitting the battery back in and getting dirty. The only thing is the leads from the charger might not be long enough to put it on the ground (on a brick) and I don't want to leave the bonnet up. Hopefully someone will be in tomorrow to get the new battery. Quote Link to comment Share on other sites More sharing options...
SMARTLY Posted November 26, 2013 Report Share Posted November 26, 2013 I used to stand my charger on top of something in the engine compartment that allowed me to close the bonnet, guess your engine might be a bit big for that. Quote Link to comment Share on other sites More sharing options...
parthiban Posted November 26, 2013 Report Share Posted November 26, 2013 Also says suitable for petrol engines up to 1800cc? Quote Link to comment Share on other sites More sharing options...
Rich Posted November 26, 2013 Author Report Share Posted November 26, 2013 It's a battery charger (I don't actually have that one) so engine size should be irrelevant. I could understand that if it was a battery jump starter pack but it's not. Quote Link to comment Share on other sites More sharing options...
Tony Posted November 26, 2013 Report Share Posted November 26, 2013 Remove the black ( Earth ) first and connect it last. Quote Link to comment Share on other sites More sharing options...
Rich Posted November 26, 2013 Author Report Share Posted November 26, 2013 Yep I know Tony, removed plenty of batteries I decided to take it out to charge and it was full in 30 minutes. So might leave it in a trickle charge overnight. Quote Link to comment Share on other sites More sharing options...
Rich Posted November 26, 2013 Author Report Share Posted November 26, 2013 Found the instructions for my charger and it will do up to 70ah so can't see many cars using that. Quote Link to comment Share on other sites More sharing options...
Tony Posted November 28, 2013 Report Share Posted November 28, 2013 What as in to low a rate. Quote Link to comment Share on other sites More sharing options...
Rich Posted November 29, 2013 Author Report Share Posted November 29, 2013 No too high I would've though? Most batteries I've seen are 45-50Ah, some 60Ah but never 70, not for a car anyway. Quote Link to comment Share on other sites More sharing options...
parthiban Posted November 29, 2013 Report Share Posted November 29, 2013 True no idea what the 1800cc thing was about, you're right I doubt many car batteries go over 70Ah. Quote Link to comment Share on other sites More sharing options...
