Yes, it's a garage in my house and completely protected. However, my reasons to lock are laughable - I like the lock chirp and the whole light flash/mirror fold and that got me into locking. Then, recently I set up my digital key and also integrated the key to my Apple watch, and I love operating it with my watch. For my decision to lock during the charging process, I thought that if I do not lock the vehicle then it will be in a semi-ready state and will keep consuming more battery. I did not realize that in lock state it will try to initialize some of the systems and may conflict with the trunk open position.

Exceeded the 24-hour mark, and it's still at stage 3. I will leave it on for 30 hours, if the stage does not change then will unplug. The charger guide says max 30 hours for stage three.

I am guessing your charger might be bad. I was having the same issue. I bought a new CTEK MXS 5.0 and set it up for agm charge. Charger ran for about 7 hours total and turned green. No errors on car. Returned the other ctek charger.

You don't happen to have a multimeter to check the voltage at the charging terminals?

I think so too. I just now ordered a CTEK MXS 5.0, exp[ected to be delivered this evening. Will attempt tonight using the new charger.

No, I don't. You think I should get one just to check the charging condition?

A multimeter is a handy tool, but only if you know or learn how to use it safely and how to interpret the results. Otherwise, it can lead you astray and potentially be dangerous, depending on what you're measuring, and how you're doing it. A decent one doesn't have to cost a whole lot, but high quality ones with lots of useful extra features (like acv or dcv current measuring) can start to be, and may not be worth it for the average user.

2021 X5, The same message “battery management” comes out when charging with CTEK MXS 5.0. All the doors closed except hood. The charger is still in stage 3 after 8hours, will take a look tmr morning if it will complete the charging process.

aha, same behavior as mine using BMW charger. I got a CTEK 5.0 and have connected on Car - AGM mode. The charging stage switched to three within minutes. I will see how it progresses. This is kinda becoming a weird situation.

I checkd my CTEK MXS5.0 this morning, it's still on stage 3 after 20hours, weird. Anyone here has no any issues when chargering 2021 x5 with CTEK 5.0?

If you just want to check voltages and resistances, many of them out there are okay. As to a reliable brand, Fluke is top notch. That doesn't mean they are the least expensive. On any one you buy, you'd want it to be rated for at least CAT III and use banana plugs to attach to the meter as those are less likely to slide out, exposing you to potential contact with the power. This is a basic, Fluke meter https://www.amazon.com/Fluke-101-Mul...453929&sr=8-22
If you want to measure current, then they get more expensive. There are two ways to measure current, by inductance (no actual contact) or by putting the meter in series with the load, and it depends on whether you're trying to measure ac or dc current, as not all can do both. The common lead is your reference. If you're measuring a battery, and you put the common lead on the + side and the other lead on the - side, you'd measure negative 1.5vdc or so if it was say an AA battery. If you put the common lead on the negative side, and the other on the plus, you'd read positive 1.5vdc...so, knowing where your reference point is can change the meaning of the readout you get. trying to read DCV when you have the meter set to ACV, you'd read zero, or close to it. Some manuals are better than others, and there are a lot of YouTube videos and tutorials you can view. It's easy to be mislead with a reading if you don't understand what's going on. At least most of the better meters are autoranging, so you won't damage them or get unusable answers with an overload in most anything you'd try to measure on a vehicle. |

I keep the hood fully open while have my charger on for overnight charging. No issue whatsoever.....Usually starts at stage 3 and after overnight, it comes to stage 7
