Battery Issues - Exide Orbital Blue - Deaded?

then you are lucky. @ 10.5V they were easily salvagable.

That's an interesting read. As per normal , there's always someone trying to make something better and as a result there's a compromise (factory parts always work best).
In this case no car should never get the voltage close to or above 14.7 volts .....because certain parts of the car's electronics have 14.7 volt zener diodes in them to protect against overvoltage. The best example being the V1 radar detector........and that's fact as in FACT.

Speaking of dead batteries.........I've changed heaps of batteries in UPSs. What a joke, you get told that you need a UPS for your server/phones whatever.......it sits there for 2 years with no maintainence, get the first power cut and it all falls over in 2 minutes.
Because the gel cells just sit there doing nothing and don't get cycled they loose capacity. The cases swell up which is the big give away.The only way to test them properly is to turn off the mains, which is really best done after hours. Not cars but still batteries.
Then of course theres the (50V) lead acid batteries in telephone exchanges (the bigger ones where one cell is big enough to take a bath in) which at least used to get regular (proper) maintainence and would last for at least 20 years.

And proof of the exact opposite of what you were saying...

They need a slow charge, that's why you buy a special charger, it's on the specs.

Because the gel cells just sit there doing nothing and don't get cycled they loose capacity. The cases swell up which is the big give away.

The cases swell up because the charger isn't working correctly and they gas, not because they sit there doing nothing. Besides which anyone that doesn't check their UPS capacity every six months or so is just asking for trouble.

[QikStarlie]

yeh, at work the only ones we come across that have swollen up, is due to a faulty charger. or have shorted out on some tools in the back of the car!

Put it into a car with a 100 amp alternator, it charges too fast, overheats and it's toast.

They're for race cars only with a low output alternator. The importers might end up going broke with warranty claims.

so after reading the links you posted up, the part in bold is correct.
but not for the reasons you list

Faulty charger......haha.

They always come right with new batteries......that's just the usual salesmans BS, translated into english........you need a new UPS at the cost of ............4 times the cost of fixing it.

No, the real joke here is you believing that lead acid batteries somehow benefit from cycling.

They always come right with new batteries

And they're fscked again in another year because the charger either charges at too higher rate, and/or it doesn't drop the float voltage back to around 13.2-13.5v when they are fully charged and the cells gas, which is not good in a sealed system.

Gassing is not good in any Battery, gassing = loss of electrolyte = loss of capacity.
As having bigger alternator has nothing to do with charging too fast batteries.
If you battery takes 20 or something amps at 14V, it means it is either a 200Ah battery or it is poked.
Alternators these days are electronically regulated, so once they have reference they would regulate relatively well (to a certain voltage). And they don't regulate how much current goes to battery either.
Technically the lead acid battery is somewhat self regulated, that is why the chargers are very simple on it.
