batteries in general

My understanding is batteries are made equal, in other words a battery that is tagged 650cca is the same as one tagged 1000cca. When batteries are made they are made the same and then tagged with the specifications per battery and I believe that deep cell batteries are the same.
Is this true?
Thanks Wayne

Not at all true.. First CCA is only imporatan for starting batteries.

Starting batteries have many thin plates, this means lots and lots of contact area and a high Peak Amps (Cranking or cold cranking amps) rating.

DEEP CYCLE batteries have thicker plates.. They are designed not for the short run (Starting batteries are designed for 30 second runs) but for the LONG HAUL (hours and hours of providing power)

Some batteries are "Cross bread" Slightly thicker, but not really DEEP CYCLE.

Next we get to the quality of the product.. Some the plates are of higher quality, some brands not so high.

Then ther are the other features (FLooded/Sealed/AGM for example)

so no, all batteries are clearly not made equal.


Oh the CCA.. If your vehicle neads more cranking amps. A group 24 won't make you happy.

In the old days I worked for a couple years as a Tow Truck Dispatcher. We had some Jump Starters.. One was my portable car (I call it that for it ran 12 volt stuff like a car's 12 volt outlet does) it was 600 peak amps and would not jump start a motorcycle.

Another was my Jump Start Pack, 1,000 peak amps and would jump start the TOW TRUCK. I think the ones the driver's carried was around 900 Peak amps.. So no, not all batteies are equal.

Hope for the best.

Prepare for a lecture if MEX sees this post

Thanks to all who responded, you have answered my question.

Warranty YES, rating NO

Wayne GOOGLE Trojan btry and read

Go lift a 650 CCA and then lift a 1000 CCA. Big difference in weight, which I imagine has to do with the number and size of the lead plates.

If that was true the Fair Trade Commission would have a field day.

Yes most batteries are made the same way but it is the differences in materials and components that affect the CCA rating.

No it is not true.

Not true.

Check the actual weight and compare. Off brands might be playing games, but I don't know if they are.
