I've had a few low battery warnings flash up on my screen, probably because I haven't been doing enough mileage.
I did wonder though if my car is fitted with a Moll battery that have been giving so much trouble.
Is there a way to identify a Moll battery i.e. is there a visible name on it ? The only writing on top of my battery that looks like it could be a name is BANNER, but I've no idea if that's the make or not.
My wife's Rapid regularly displayed these warnings from when she got it at 3 months old until about three months ago when it was 3 years old. I got sick of seeing the warning so I bought an AA branded Smart Charger, and after 24 hours on charge the charger showed the battery as fully charged. The warnings stopped, and I have only seen the warning once since then, about two weeks ago. She only does short runs in the car so probably not doing enough to top up the battery fully. If the warnings become regular again I will use the charger again. When the warnings were occurring the Stop/Start on the Rapid never worked, one of the conditions for it to work is that the battery has to be charged to a predetermined level. Once the 24 hour charge had been done the Stop/Start began working. Coincidentally the Rapid has a MOLL battery, but it has been checked and is not faulty.

Thanks for the info guys. I had the warning again today, so I'll charge the battery and if it continues, I'll visit the dealer.

Well, my voltmeter turned up today from the Phillipines - they don't tell you that until after placing the order !! - so I plugged it into the car with the engine not running and it reads 11.5 V. Trouble is I don't know if that's a good figure or not, what do you think chaps ??

At 11.5V if correct/accurate I would say battery goosed.

Thanks for those figures Kenny.
I sat in the car earlier with the engine running whilst I downloaded new maps into the infotainment system. There was nothing else running and I had a reading of 14.6 V.
Still not quite sure what to make of this, although I'm pretty certain that if I took it to my dealer, they'd say it's not getting charged up due to the predominantly short runs I do. I had no trouble with it when I took it to France in September where I was doing a much higher mileage.
I might still have a word with the dealer and/or I might get myself a little CTEK battery charger.

Got myself a trickle charger today (an AA one - only £20). I took the unusual step of having a look the car handbook :shock: to check where to affix the crocodile clips to and noticed that it mentioned that short trips are not sufficient to keep the battery fully charged.
A good deal of my driving is only local, so I rather think that it's the cause of the low battery warnings showing on the screen.

Where did you find the text about short trips? I usually read the manual fairly completely when I get a new car, but I don't recall seeing that. 🤔

Battery discharge Frequent short journeys will not sufficiently recharge the car battery.
It's on page 283 of the online manual under the heading BATTERY DISCHARGE.
I actually saw it in the manual in the car but I can't remember which page it was on.

The charging system uses smart “alternator technology” and during normal running the alternator is switched off to save fuel where possible , the alternator tends to only charge on engine over run or braking. It also never fully charges the battery to allow for this regenerative energy to be harnessed.
Some useful info here, the micro hybrid 1, 2 bits are relevant..
