I recently bought a 2019 X5 with 37k miles. It has the original battery.
Would anyone recommend preemptively replacing the battery before issues arise? The battery should only last another year or so right? |

I would not change it proactively.
Just wait till it starts showing issues like when cranking. Then get it load tested as such and replace at that time. |

I wouldn't. Just get a good trickle charger and have it hooked up periodically to get it to full charge.

How about just get the battery tested? You will need to tske it out of car, but it is a 30 min test.

To the OP, personally I would wait until the first sign that it's getting weak (slow start, strange electrical issues etc.) before replacing.

Was it connected to car or removed.... I generally remove it, charge it, let it rest... then bring it to the local AutoZone, etc . Most of them use a Midtronics which generally won't return a false positive But usually, once it starts cranking iffy, it's a good case to swap it out. A decent AGM is cheap enough these days....although they do appear to have gone up a bit since a few years ago, since the last time I looked at pricing on them.

Yes, I don’t try to squeeze the last bit of use out of a battery, not worth the potential hassle. I consider them maintenance items.

Sucks when you get a misdiagnosis. Hopefully the 2nd time of crank was just it and it wasn't a symptom where it ran out of juice on you. Between Efficient Dynamics and understanding how all batteries do like to be at full SOC and how the alt. operates....2fold on just replace when crank shows the obvious issue. Nothing worse than it dying while driving. |
