Just came across an issue I was unaware of in regards to 12v batteries. I just replaced my AGM after only 9 months of use.
The battery shop suggested that the battery I had may not be a true AGM battery. Primarily because of it's construction and weight. The top had the standard clamp post plus screw posts. Apparently this is uncommon on true AGM batteries and usually indicative of a cheap Chinese knock-off. Also the top of the battery had standard shaped and vented refill caps, whereas AGM should be a couple of long sealed caps. My dead battery weighed around 25kg for a 100ah, the new 120ah is 33kg. He said this is also an indicator.
He suggested a couple of franchise type stores may be pulling the stunt of cheap imports rebranded to resemble genuine brands.
