Thread: Expanded Calcium-Calcium battery

Why don't you jump start the Landcruiser, let it run for a bit, and see if the alternator does a better job of charging up the battery?

It's in a series of pieces

I was going to put it in the Disco, jump it and drive around, but it won't fit (too long by a mile)

I have a projector IC1500, you are welcomed to use it. You know were I am OR I can take it into work and you can pick it up in the CBD.

10.5V doesn't sound promising, actually sounds more like a dead cell....

and FWIW I've read that calcium/calcium batteries require a higher charging voltage than lead/acid and AGM types, something like 15V minimum.

I was worried about my two in the 'fender after too long without a charge, but surprisingly they came back up OK.
I alternated them between an old fashioned 10amp Arlec and a trickle/float charger over several days.
So far so good.....

Actually to be honest I'm not sure it is calcium, it this one, says calcium grid on it Supercharge Batteries - Car Batteries, Maintenance, Expanded Grid Technology , looks just like an ordinary flooded maintenance free.

That IC1500 looks horn, cheers, shall be in contact

If it's a Supercharge, that's what i have and they are a calcium/calcium.

The one on the Patrol died (dropped cell) yet it still measured something like 12V and shows green in the sight glass.

Replaced with a Delco calcium battery ('cause that's what the local tyre bloke stocks )

If you are using a standard charger it will not charge the calcium battery properly. You need a specific charger for calcium batteries. Not sure if it will do any damage though.
I currently have 4 charger, 1 HD workshop charger and 3 muti stage maintenance chargers and none of them will charge the calcium in the D2.

Hi B92, at 10v, the battery is probably stuffed so you can’t damage it any further by trying any charger on it.

There a bit of a misconception about C/C batteries. While you can’t fully charge them with an alternator or standard battery charge, you can charge them to around 95% to 97% and if they are never fully charged, it doesn’t seem to have any effect on the use or the life span.

By the way, if your charger is only a 2 amp charger, it will probably take a few days to charge the battery and charging it slowly is actually far better for the battery so try charging it for a day or two more but keep an eye on both the voltage and the temperature of the battery while you charge it.

Also, how long did you leave it for?
