Thread: D2 charging rate

I don't have definite figures but those voltages seem right for the D2.

Hopefully I wont regret posting this but here goes
Hi ,
I work for a battery company that makes calcium/calcium batteries and I can tell you 100% that calcium batteries do like to run at higher volatges than lead antimonial types. If a car is designed to have a calcium battery then it should be replaced with one. We have seen problems when a calcium is fitted to older cars. Calcium batteries survive better in higher temps compared to L/A types also. Optimal voltage for a calcium battery is around 14.8 volts, so I think your charge rate is perfect.

Hi Andrew, some of those battery monitors can be a fair way off the correct voltage so if you can get your hands on a good quality multi meter at some time and check to see just how accurate the meter is.

Having said that, the running voltage for a D2 is 14.7 so that’s pretty close.



Hi noki 3.9, I agree with you on replacing Calcium batteries with Calcium batteries. When I was getting the data from Land Rover Australia for the development of our new dual battery controllers for the D3s, the techie at LRA said that they expect to see some problems down the road when the D3s start to need battery replacements and people don’t fit the exact same battery.

The D3’s whole electrical system is optimised to get the best results while using a Calcium/Lead/Calcium battery. I think we are going to see some very interesting effects when people fit different type batteries.

The D2s are in the same boat.

Cheers

Thanks guys
Did test it with my multimeter at the battery,was only .2 or so different.
Did a trip up to Perth today,was getting 14.7 to 14.9 most of the time with the aircon on and fan @2 or 3.The 15+ drops after 5 mins or so,I guess its pretty normal from the above posts.
Thanks
Andrew

hmmm, ok.

so BUB002 had a battery replaced at some stage before I bought it,, its purple, and was supplied by the VIC RACQ,, so I'm guessing its a normal lead type(but will check)

what things should I be on the lookout for??

model 4703
640cca


oh, and if nothing else,,
found an undone battery clamp

Hi, If your battery is a calcium/calcium then it will be totally sealed, no caps at all, but if its a normal type it will have caps.
Im not sure of what brand the Racv uses but I doubt that it would be a calcium. These are some brands that make calcium....SuperCharge...Delcor....AcDelco....Bx Atlas....
When buying your next battery ask if its a Calcium Calcium = both pos and neg plates are calcium, dont get a hybrid which will have a calcium and something else. It has been proven that these types are not so good. There is a company that states that hybrids are better for Australian conditions
But then again Landrovers where not designed for Australian conditions.
Calcium calcium batteries are used extensively throughout America, Europe, and Asia and now Australia
Gday Drivesafe...

14.7 to 14.9 most of the time......

I'm sick of this nonsense.

Why is my alternator charge rate 13.2 to 14.1

Most of the time it is running 13.2 to 13.8.

Anything to check before I fling the POS

Hi Feral
What type of battery????
I aint no auto ellecy but the alternator will only produce what the battery wants to take(well to my understanding).
Wondering if a normal type lead/acid battery has gone in at some stage and the higher alternator output has cooked it somewhat.
Drivesafe or Noki have probably got the answer.
