Calcium Batteries - What?!

Hi Folks,

We was just walkin up the street here in Malaysia lookin, lookin.... and found a battery shop.

They say: "I get you 200 amp hour deep cycle Calcium battery. You give me $200 I get it 1 hour".

I say: "Hang on horsey. I no hear about Calcium battery. You make up!?"

So the question is: whats a Calcium Battery and is it any good for a house battery?



Mark
PS I have read some other threads where its mentioned, but no definitive knowledge.

There are two common sealed Lead-acid battery technologies - one is lead antimony and the other is lead calcium. There are different advantages/disadvantages to both types, I seem to recall that the calcium ones, all other factors being the same, could give more CCAs. My charger has slightly different charge settings and curves for both types, so you really wouldn't want to mix both types.

Short Answers...

After a quick check of the internet (now an expert) a calcium battery has a small amount of calcium alloyed with the lead, as opposed a "normal" battery that has antimony.

They are reported to have a lower self discharge rate, but are not as suited to repeated charging. They need a different charging regime.

So, maybe good for starter battery, not as good for house battery.

Zanshin & Boracay are on the money Mark. Just a slightly different FLA battery. Certainly not a gel or AGM and not fully sealed.

You might be wrong. I believe some Gel batteries use
Calcium/Calcium metal alloys.

I believe most AGMs use calcium instead of antimony. That's where low self-discharge comes from.

They are fine!

Best investment I've ever made!

I was just thinking to slowly buy new ones when I see some at the right price. But the 3 telecomunications rack batteries are sensational! <<Touch wood!>> Having 300 amp hours after doing the Pacific on 110 amphours is like living in a differnt world! Beer - Its COLD!!!!!!!! We use the fridge and the autopilot at the same time... and the lap top, and lights to see the keyboard

But I do want to upgrade to 2 x 200amp hour agm's soon. I want to have long term confidence


They can come in at $1,000 each so looking for a deal!

Here in Sausalito I just purchased two 210amp Lifeline batteries for $500 apiece. Perhaps you should swing by.

Yeah, you could be right however I haven't heard of the Gel technology (or even AGM) ever being referred to Calcium batteries.

Around here, when someone talks of Calcium batteries they are referring to a vented FLA with some calcium chemistry in it. It's late and I am too lazy to look up the fine details but such batteries are sold on it CCA abilities so I am guessing they aren't going to as suitable as others for a house battery.

Might be different in other woods.

That is good , but my guess is your the kind of guy who wouldn’t mind cracking a couple of warm ones as a last resort .

Good luck with the beer and batteries.

I am sure if you gave him $200 bucks up front he can get you anything in 1 hour. Just make sure you take a photo of him and the $200 bucks as a momento...

Which side of 30 degrees North are you?

"Sea Life" has a rule. She never goes colder than 30 degrees North or South.
Maybe you can pop over and drop a couple off?
