Battery Help...

[psychoticgroove]

Gday Folks.


Woke up this morning to a flat battery. Called RAA, guy rocks up half hr later, checks 2 cells and says charge is flat must've left something on (i was pretty sure i didn't). He then said I would need to get it to a professional charging place but if i keep it running for half an hr, it should be ok for the day.
So i let it run, go get dressed for work, come back switch it off to lock up the house (house keys with car keys), go back to start it again and it still wouldn't start (after running for 40minutes).
Called up RAA again, different dude rocks up who checks all cells and diagnosed that one of the cells had failed. The battery was an RAA battery, 18 days out of warranty (2 years)!! FML

My question is, what are my safe options? Do i go with:

RAA regular battery- $138 @ 2 year warranty (same as before)
RAA heavy duty maintenance free battery- $153 @ 3 year warranty
Battery World (century regular)- $150 @ 2 year warranty
Battery World (century heavy duty maintenance free)- $170 @ 2 year warranty
Battery World (century hi performance)- $189 @ 3 year warranty
They are all the effin same, Go Repco/ Sprint auto/ Supercheap auto battery

Suggestions from personal experiences would be highly helpful.

Cheers
