Century battery leaking
so i bought a new Century battery back in July, and noticed on the weekend that it's leaked, making some nice corrosion into the passenger rear seatal area and boot. Cleaned it up, and more leaking evident today. Stopped back to Supercheap today, and they ask, has it been dropped? No...it's safely secured in stock mounting area (boot, in R33). Is it overcharging? No, according to my apexi and defi digital gauges it's exactly in the prime charging range. Has it been overfilled? no buddy, apart from a small topup yesterday after I noticed it leaked, it's as I bought it. They say, well that's the only reason it would ever leak. I say, you're forgetting about manufacturing fault. They're now saying, can't do anything unless I give them back the battery and they send it back to Century for further testing (who, call me sceptical, will likely claim there's nothing wrong with it) meaning if i want to drive in the meantime, will have to buy another battery (NOT a Century). I ran a Supercharge battery without any issue until it suddenly died about 6 weeks after the 3 year warranty expired, on exactly the same setup and my alternator is a fairly new Bosch, so wouldn't think there's anything wrong with my setup. Anything else to cover or check, before I call my legal dept about launching a claim for refund of purchase and damage to my car?
