    Hey all hope you are all doing fine and keeping safe in these challenging times.

    So people with ctek mxs 5.0 chargers, I had my M3 in storage for around 1 year maybe less, I hooked up the ctek mxs 5.0 and for 4 days now its been on number 7 with a green light I was under the impression that it should go to setting 8 and then pulse charge the battery whenever is needed on the dip of voltage 98% charge then drops to around 85% 90% and recharges it to keep the battery healthy?

    Or am I wrong does the charge sometimes switch to Number 8 when I don't see it? doesn't seem to be a problem car is now starting fine again but I must keep it connected for now as my tracker is draining the battery in 3 days without and I must have someone remove it so the car will start without the tracker...

    Anyone used these for a while and maybe knows more? seems a very decent bit of kit it managed to get my battery back after I forgot to charge it for 10 months at least.

    Thanks Ad.

    Hi - I have a similar experience. I used to park on the street and we hardly use the m3 now as we tend to use the family wagon with our todler - so the battery went flat a few times - and I had to jump-start the car, which I don’t think does it much good.

    We’ve since moved house, so now have a garage, and again I left the m3 to go flat, and the ctek (same model as yours) wouldn't charge it at first - although this was back in the depths of winter when it was bloody cold outside - so I removed the battery and brought it inside to warm it up(!) and it charged up fine - and is now on trickle charge. It doesn’t reach 8 either - but on other cars it would. No idea if it’s because I’ve damaged the battery, perhaps by letting run flat so many times...?

    I’ve had a few cteks and they’re excellent chargers - only replaced them as the power/mode button can sometimes become temperamental.... or where I’ve run them over!

    Will only hit number 8 after 10 days of uninterrupted charge-

    They are superb - love mine

    In 6 years of having Cteks I’ve never had an issue with my battery

    Swear by them
