Thread: Dolium Battery Monitor in a D3 2.7

I had 1 on my D2 and the alarm drove me crazy..It would go off like you say even connected to a new battery not even in the car..

I threw it in the bin, after several calls from SWMBO complaining about a bloody alarm going off in the car and it flashing like a christmas tree as you say.

Cheers Ean

Hi Allan,

I looked at the Doium a couple of years ago for our D3 but gave it a miss. The D3 charging circuit often exceeds 14.7v, and I note the specs for the Dolium indicate the over-charging warning comes on at 14.65v. I was under the impression many vehicles will have a charge rate of up to 14.7v which means the Dolium is likely to come on freguently in some vehicles.

I have seen readings as high as 15.2v on our D3, which LR tells me is 'normal' as the computer controls the output from the alternator; not the regulator. This is supposedly why the D3 and RRS have a calcium battery instead of a standard lead-acid variety. I'm not a sparky and I may have been fed some misinformation, but given I have just replaced my original battery after five years, I can only assume this is 'normal' (for a D3). Most of the time, the voltage reading seems to sit around the low14s/high 13s, peaking at 14.7v+ as the computer deems necessary.

Thanks for that ,your advice seems to make a lot of sense.
