I would think you may have gotten a bum battery.

It shouldn't go flat quickly being unhooked unless it'* set on concrete.

I agree with Boosty. Sounds as if the battery may have internal leakage and is self discharging that way. Good call on the concrete, too as I don't know how many pay attention to that.

It does sounds as if the alternator is doing its job. Can you measure the battery voltage when it should have a full charge? Or take it back where you bought it, and have them test it. If it was dead when you bought it - that would point to a bad battery.

I have never experienced a new battery with NO or little charge. Take it back for refund or exchange. It is probably defective.

You got it from the Americans....oh geez.. return it.. If it was totally dead when you got it..it was defective from the start.

Concrete? as opposed to a metal shelf? mud? what is the story here?

i appoligize in advance for the highjack.

A battery stored on a bare concrete floor will discharge very quickly and will eventually be damaged. I store my marine battery in a plastic carrier that is in a cardboard box.

OK, I just did a search and found out that the battery storage on a concrete floor concern is a myth (based on a previous truth).

Here:

Quote:
14.1. Storing a battery on a concrete floor will discharge them.

All lead-acid batteries will naturally self-discharge which can result in loss of capacity from sulfation. The rate of self-discharge is most influenced by the temperature of the battery'* electrolyte and the chemistry of the plates. This self-discharge is often mistaken for concrete floor causing the battery to drain. Some experts believe that storing car or deep cycle batteries on a colder concrete floor might actually slow down the self-discharge (leakage) rate because the floor acts as a heat sink and cools the battery. (Please see Section 13 for more information on storing batteries and Section 1 for more information on sulfation.

In the early 1900s, when battery cases were made of porous materials such as tar-lined wood boxes, storing batteries on concrete floor would accelerate their natural self-discharge due to external leakage. Modern battery cases are made of polypropylene or hard rubber. These cases are sealed better, so external leakage-causing discharge is no longer a problem, provided the top of the battery is clean and free from wet or dried electrolyte and the same temperature as the floor.

Large differences in temperature could cause electrolyte stratification within very large batteries (>250 AH) which could accelerate it'* internal "leakage" or self-discharge if the battery is sitting on an extremely cold concrete, stone or steel floor in a warm room, boat or submarine. Stirrers or bubblers are often used on these types of large batteries to keep the electrolyte from stratifying. Undercharging will also cause electrolyte stratification, which can also result in loss of capacity from sulfation.
This info came from a great site on car batteries, HERE

This site also contains some really good info regarding your issue, bonne boy, and seems to indicate that what happened to your battery is that it was discharged too much either before or during shipping from the U.*. It will never recover.

Quote:
While a battery is in storage or not being used, the discharge is a result of parasitic load or natural self-discharge. Parasitic load is the constant electrical load present on a battery while it is installed in a vehicle even when the ignition key is turned off. The load is from the continuous operation of electrical appliances, such as an emissions computer, clock, security system, maintenance of radio station presets, etc. While disconnecting the negative battery cable will eliminate the parasitic load, it has no affect on the natural self-discharge of battery. Thus, permanent sulfation can be a huge problem for lead-acid batteries while sitting for long periods on a dealer'* shelf, in a basement, cellar, barn or garage, or in a parked vehicle, especially in hot temperatures.

Mike...thanks for digging into that information. Great to have the correct information vs. the old school myth as we all can have now misinformation from sources that are out of date.

No more concrete floor worries for me.
