but more common that you may think!
I had the same thing with my Century.
Took it back to Supercheap to get them to test and replace it, they tested it, but of course the 15min drive there gave it just enough charge to make it appear as tho all was good(I knew otherwise).
I have a dual battery setup, so my bad for not doing it right that first time ..
So a few weeks later, running late to get little miss 14 to school one morning, not only was the battery dead, the easy jump start button I installed on the DBS only drained the more than acceptable charge/reserve that the aux battery had, instead of assisting the start battery.
Pulled the earth lead on the dead battery, used the jump leads started 'er up, little miss 14 now at school(only just in time) ..
Luckily the Century rep was there when I got there, and I asked him to test it .. etc, etc. Supercheapo had to relent [thumbsupbig]
if this new one dies too in less than 12 months, I'm dumping it at the closest battery recycler and never dealing with Century ever again.
