    These warnings just showed up this morning. I haven't driven the M3 for almost 2 weeks but I regularly start the engine every morning. It has the Yuasa EFB installed last Dec 2019 (2 years and 5 months).

    Did a specific gravity test 2 weeks ago. The level is still within the green zone but almost near the white zone.

    Drove the car for 10 km and restarted it. The warnings were gone.

    Looks like the battery is hinting for a replacement? Click image for larger version.

    To recover charge lost from each start, you gotta run the engine for around 25mins. If less, you're not doing your batt any favors.
    With petrol prices these days...grab a smart charger like the CTEK MXS 5.0. It reconditions, too.

    Yup, especially during the lockdown the CTEK charger was very very handy. I also use it for ordinary Motolite batteries. I think I was able to extend at least 1 year for 4 Motolite batteries since I bought the CTEK way back 2018.

    The warranty coverage is superb. Back in 2021 during the lockdown, the CTEK charger stopped working. I brought the charger to a nearby Blade store to request for a warranty replacement. Got a brand new one after 2 months.

    Thanks sir Travs. I regularly charge my M3's battery with CTEK since 2018. I can't do that anymore after I moved in to a condo unit last April [emoji28]

    I'll probably just drive the M3 every morning around C5. A good excuse to go out for some fun drive [emoji106]

    Quick update.

    No more warnings after driving the M3 at regular intervals (at least twice a week for 10km).

    I inspected the specific gravity of the Yuasa batt fluids. It's still within the green zone but almost near the white zone boundary. Battery is now 2 years and 7 months old.

    I can't use my CTEK charger anymore since my M3 is parked at a condo parking area. My only option for now to keep the batt juice healthy is to drive around.
