I have a 2017 nitro Z21 w/12" elite ti in console and an 9" elite ti and a hydrowave up front, a genius 4bank 40amp charger. I have an Interstate AGM 31m cranking battery. This battery is 3 months old (Interstate warrantied the first one). The battery is going dead by 10am and all I'm running is the graphs and the hydrowave. I would expect the battery to hold enough of a charge to run this equipment and still start the engine after a day on the water let alone 3hrs, is anyone else having this issue?
