I have just bought a “NAPA DIN65LHX MF 12v 710cca Premium Performance Battery” for my car. I can’t find a data sheet for it and there is nothing on the battery to confirm if it’s Calcium or not. I contacted the company I bought it from and they said it doesn’t matter just charge it on any lead acid charger as there isn’t any difference.

My reply (which I believe is correct) was : -
Typical absorption voltage range for a standard lead plate flooded battery is 14.2 to 14.5 volts .
Calcium and Silver Alloys types, the Charging rates must exceed 14.8v up to a max of 16v during the charging process to successfully charge these batteries.
This means that a standard lead plated lead acid battery will over heat(?) if charged on a ‘Calcium’ plate setting and shorten that batteries life.
Where as a ‘Calcium’ plate battery will not fully charge if charged on a standard Lead plate setting.

They said not true none of the 300+ chargers they sell has a ‘Calcium’ setting.
Well, my POWER TRAIN 12 VOLT 30 AMP 240 VOLT AC 8 STAGE PTC12V30A BATTERY CHARGER has Gel, Lead Acid and Calcium modes that need setting manually before charging any battery.

So can anyone please point me at a data sheet for the “NAPA DIN65LHX MF 12v 710cca Premium Performance Battery” I bought or confirm its chemistry for me.

Thanks in advance.

p.s. if this is in the wrong place please move it to the appropriate section.

 

Oh well….. Apparently no one knows.

And, yes I have contacted NAPA and they just said ring this number, it's the technical department (doesn't work from NZ) or just ask the shop you bought it from, so they didn’t even bother to read what I wrote.

Should have spent a few $'s more and bought a Century (Yuasa) battery which states quite clearly “Plate design: Silver Calcium”.
NAPA $269 vs Century $329 (Down from $499.... Welcome to New Zealand, nothing is cheaper than extortionate).

Who are NAPA anyway? Never heard of them before buying this battery.
OK, thanks anyway.

OK, for anyone interested I did some sleuthing...
Seeing as NAPA NZ just gave me the runaround and I got no answer as with the NZ outlet I bought it from who blissfully believe that all car batteries can be charged on any charger that is for Lead Acid and that a charger with a Calcium setting is a myth as none of their 300+ chargers that they sell has a Calcium setting (thanks for that Mr.Positive).
There was a label on the top of the battery with a bar code on it (9415951010069) which basically comes back as a NAPA DIN65LHX MF battery and I couldn't find a data sheet anywhere for it.
This label was stuck over another label so with the surreptitious use of a small amount of "de-solv-it" I managed to remove the first label.
The label underneath had a different barcode (94159510089740) which shows it as a Yuasa DIN65LHX-MF battery (Century-Yuasa).
I was able to phone them and a Yuasa Tech confirmed that this battery is a Calcium/Silver plate battery and needs to be charged on a Calcium setting on a charger.
Charging it on a Lead acid setting will only partially charge it.

So how does this calcium battery get a full charge once installed in your car? Cars alternator wont put out 16v.

btw never heard of these calcium plate batteries before. But its strange its not stated on the battery itself. Especially since it needs a special charging routine
