Thanks evelrod, I am not trying to use as a booster to try and start the car. The battery becomes slightly discharged when stood in cold period for couple of weeks of no use and the BSI computer is draining a little power all the time, I just give battery a top up charge with 3.6amp or 6amp...
Thanks IRstuff, by IR drop I think you may mean resistance could make my 6amp charger work like a 3 or 4 amp which would be fine as steady charge is better, when battery won't operate starter solenoid it wipes out BSI computer settings, my little LED readout tester shows 12.5v and I took battery...
It is for charging car battery, maximum 6amp charger may even use my 3.6amp electronic charger I have, the orange cable I was going to use is same as used for mains B&D lawn mower, it looks thicker cores than that fitted to charger, I was concerned about voltage drop over length of cable if any...
I don't like mains wires stretching across drive unattended so instead of putting car battery charger under bonnet I was thinking of extending the 12v output leads to 10 mtr so charger in house just 12v running outside.
Would I lose any output voltage due to longer output cable or would it still...
