    Like waiting for Xmas so it is....
    Freezing temps today, so that won’t have helped the charge rate.

    So true... Reminds me of an engineer I knew, when asked for something to be done. "Give me more time and I'll get it done more quickly".:)

    Be aware guys if you lock the car while charging and then hours later unlock and open the bonnet to check for the green light - you may not see it, and think that the battery still needs a fair bit more charging.

    The simple act of unlocking, opening a door, and pulling the bonnet catch wakens up the car and in many cases switches on a whole collection of lights, including in my case the headlights and/or the DRLs - thereby turning off the green light and the charger recommences serious charging rather than the 'trickle' state it had been in with the green light on.

    Where possible it's better to leave the bonnet a ajar and then lock the doors - so you can lift the bonnet and have a look for the green light.

    Obviously I wouldn't advise doing that overnight on your drive though - some toerag might very well make off with the engine in the wee small hours. :eek::eek::D

    Just taken mine off charge and it was through to programme 7 and showing a solid green light.

    I will see what voltage the battery shows in the morning.

    Somebody, who shall remain nameless, switched the plug off at the wall around 4:30pm, so I’ve brought it all in. Will plug back in first thing in the morning, the CTEK should remember the last state and take it from there.
    The extension cable went through the bay window opener, so can’t leave that at night.

    Got the low battery warning sign on the 435 I last night , Probably due to short night time runs due to lockdown in winter. Hardly doing any miles at all just now . Just connected my cheapo enterprises proudly presents 10 year old Lidl Battery Charger last night in the garage , set it for car 12 v and left it till this morning . No problems at all . Green lights all round

    they were selling the Ctek mxs 5.0 in Lidl this year rather than the ultimate speed charger they have sold in years gone by. sadly the price was the same as you would pay online so not a bargain

    Cold temps affecting the output? To be fair I’m not 100% sure what a strong reading should be, but would expect 12v plus.

    With a car unlocked, vehicles like ours will drop voltage with the immediate energy demand. I know for mine, not uncommon to see a drop of 0.3 - 0.4 Volts with an unlock and opening the drivers door, setting systems in operation.

    My locked car was reading 12.43V yesterday at about -1C. I checked the locked car this morning at -5C, is reading 12.39Volts. Temperature does play a factor, along with continuous energy use as time passes, due to alarm and closed system demands. Closed circuit current can be something like 9 - 21mA, depending on model. Can be up to ~80mA without any warnings.

    Happy days! Who would have thought that charging a battery could be so much fun, and of so much interest to others....a sign of the times.
