stupidsalmon Posted January 27, 2007 Report Share Posted January 27, 2007 Ive just knocked together a lamping setup consisting of a 6V cluson lamp and a 6v 8Amp. Hr. battery, i have been told to be careful when charging the battery as its possible to ****** them up somehow, the charger has a switch for both 6v and 12v charging and when charging a 12v car battery i leave it until the meter on the charger goes down to 0 ampere, is it as simple as doing the same as this with the 6v battery?

jonno 357 Posted January 27, 2007 Report Share Posted January 27, 2007 Far too much current from the charger there mate. In time it will destroy the plates in the battery jonno Quote Link to comment Share on other sites More sharing options...
kip270 Posted January 27, 2007 Report Share Posted January 27, 2007 Better off getting one of these http://www.cluson.co.uk/ChargersList.aspx Quote Link to comment Share on other sites More sharing options...
stupidsalmon Posted January 27, 2007 Author Report Share Posted January 27, 2007 ok cheers guys, out of interest what 6v batterys is that charger designed for? do you think it'd be ok to give the lamp battery one charge with it as the cluson charger obviously wont have arrived and i intend to take out the lamp tomorow evening?

stupidsalmon Posted January 27, 2007 Author Report Share Posted January 27, 2007 :blink: does noone want to risk being responsible for my battery getting destroyed, pardon my impatience but as i hope to lamp some bunnys tomorow a helpful reply would be much appreciated so i can know whether to get it on charge or not, Quote Link to comment Share on other sites More sharing options...
plexer Posted January 29, 2007 Report Share Posted January 29, 2007 That charger would charge your battery in 2 hours so it's a bit fast for that capacity battery. Would be ok on 17ah battery but really you want something pushing a bit less current for yours. Ben Quote Link to comment Share on other sites More sharing options...
pin Posted January 29, 2007 Report Share Posted January 29, 2007 If the charger was "intelligent" then 4amps wouldn't be so bad. To charge a lead acid cell you generally want a 3 stage process. 1) Constant current until the cell hits a preset voltage 2) Current backs off as the cell is saturated until a preset voltage or the current being applied is < 3% of the rated capacity of the cell 3) A trickle charge is applied to compensate for the fact that lead acid cells self discharge over time To charge a lead acid cell properly you need about 10 hours. Stage one takes about 5 hours, as does stage 2 Stage one will give you about 65-70% of rated capacity Quote Link to comment Share on other sites More sharing options...
