Does anyone know whether the Costco Kirkland Marine Deep Cycle Batteries are TRUE deep cycle batteries? My last set of batteries for my boat are the US Costco Marine/RV batteries made by Interstate and sold through costco US locations. The research I did on the Interestate RV/Marine batteries were they are NOT a true deep cycle battery but rather a hybrid and have characteristics of both a starting and a deep cycle battery. The US Interstate Marine/RV battery's don't have the Deep Cycle wording on their labels but the part numbers for the batteries have a DC in them which many people think it's a true deep cycle battery but it isn't. Canadian costco sells the Kirkland Marine Deep discharge batteries but someone on the internet says they are just the rebranded Interstate marine/RV batteries that they sell through the US costco locations.
Wondering if anyone has experience or knows whether the Kirkland Marine batteries are true deep discharge or not and whether anyone has any experience with them. Thanks.
