Many thanks for your comments on chargers. The main problem is that my car is not garaged because I do not have a garage and therefore a mains supply charger would have a power source from the house, which plainly would mean the cable would be outside. The cable would connection to the battery needing access to the boot, which troubles me little bit as it would mean gaining entry to a closed and locked boot to access the battery itself, with car outside overnight.
I am now of the opinion that I should not buy the Solar powered version because a continuous charge to the battery could be equally as damaging as a battery running out of charge. Which only leaves me the option of a mains powered smart charger, the CTEK.
A dilemma I am not certain of an answer to at this very moment, but there has just got to be an answer to the problem because I do not want to experience problems with a flat or running low on charge battery.
Much appreciated information. Regards, John
