Leroy,
none of the points you have posted above make the Extreme replicate a DEEP CYCLE battery, and I repeat Exide claim the Extreme is only a "passenger car battery" (25Kg) and NOT a Deep Cycle battery (28.5Kg) in N70 size.
As Exide very clearly explains on their web site the Extreme is only a CRANKING battery, yes it states that clearly on the Exide web site, that's not my 'opinion' that is a fact, and as I say posted on their (Exide) web site.
I have only posted on this
forum what Exide state about the Exide Extreme battery, if you or any one at all want to use the Extreme as a Deep Cycle battery that is your choice, however Exide make a Deep Cycle battery and call it the ENDURANCE, it's technical specs are vastly different to the Extreme - because it's a different battery built for a totally different purpose as fully explained by EXIDE on their website.
Your points posted above clearly indicate the Extreme battery is "
well made" and I don't dispute that at all, the weight of the two different batteries indicate clearly the different specifications as the Deep Cycle battery is 3.5 Kg heavier than the Extreme battery in the same size battery, the reason is simply because one is only a Cranking battery and the other is a Deep Cycle battery with much thicker plates than the Cranking battery, hence the extra weight and longer lasting power.
the point in question is -->
Is the Extreme battery rated as a DEEP CYCLE battery
and the simple answer is NO, it is NOT rated by Exide as a DEEP CYCLE battery.
The Exide DEEP CYCLE battery is called the ENDURANCE
and below is the relevant advertising from the Exide site;
"Built strong to withstand the pounding and vibration of marine, 4WD or heavy vehicle use, Exide Endurance Deep Cycle battery is developed for long-running power and low amperage drain.
DESIGNED to outlast ordinary car batteries in Deep Cycle applications where there is prolonged power demand from accessories and other equipment. If you require an extended power supply for operating 4x4 accessories like a winch, CB radio,
driving lights, refrigerator, extra
camp lighting, auxiliary equipment or bilge pumps, a DEEP CYCLE Battery is the BEST solution"
As you can easily read, Exide claim the ENDURANCE is superior to the EXTREME Cranking battery range because it will continue to supply power long after the Cranking battery has lost it's ability to supply constant 12v power.
And from the EXIDE web site the following information:
"What are "Deep Cycle" Batteries?
These batteries are designed to provide "deep cycle" power - making them very DIFFERENT from ordinary car batteries.
Starting a car requires a high amount of energy for a short period of time (about 5 seconds). Only a small amount of the battery's capacity is used. Once the engine starts running, the battery is recharged quickly by the alternator, which carries the basic electrical load.
On the other hand, Deep Cycle batteries supply a relatively low amount of current for a long period of time. They are specially DESIGNED to power electric trolling motors and other electrical accessories in boats and RVs.
UNLIKE ordinary car starting batteries, they can be run down and recharged (deep cycled) repeatedly with MINIMUM loss of capacity.
When a car starting battery is deep cycled, it loses capacity very rapidly and in some cases has lost its useful capacity in 50 cycles (discharges and recharges) or less.
These limitations make car batteries a POOR investment when used for marine and RV deep cycle applications.
A single deep cycle marine/RV battery will outlast 2-4 car batteries."
Leroy,
Please don't take this post as a mark of disrespect to yourself personally.
I'm only posting information that is readily available on the Exide website.
Unfortunately it states information that's not what you believe, or want to read, but it is the official EXIDE website and not my own thoughts on batteries, I'm just the 'messenger' and not the writer of the relevant EXIDE battery website information.
Hope this information assists you to understand the real difference between a Cranking battery and a Deep Cycle battery as defined by EXIDE, not by me or a '
forum' reader.
