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.
