Hello boaters. I have a quick question. I have a 2017 Hurricane CC19 with two Deka Marine Master (24M7) cranking batteries with a Perko switch to separate them. I went to tender the batteries since we are in dead of winter, and found the 2nd battery will not take a charge. My Schumacher digital charger will get it to about 73% charge and then shut down. The battery had a 12 month warranty and is now out of that date range (07/17-07/18). FYI: Most electronics on the boat go to the switch first as to not drain the batteries, but the bilge pump is direct-wired to the 2nd battery for automatic pumping even when the switch is off. Also, I have an amplifier for speakers wired with + to the perko and - to the 2nd battery. My questions:
1) Could the bilge still be drawing enough power being direct-wired to drain the battery?
2) Could the amp still be drawing current or something even wired through the Perko?
3) If I replace that one battery, could I replace it with a deep-cycle battery? This is primarily the battery that we use when parking on the lake and listening to music and running the lights. That is, do both the batteries have to be identical seeing that when we are driving the boat, I switch to "All " on the Perko to charge both. Is there an issue with having two different batteries that are connected by the switch? Also, when I replaced batteries in my diesel truck, I had to replace both at the same time. Do I need to replace both batteries since one when dead?
Thank you for all the advice. I just don't want to ruin a new battery by replacing with the wrong one.
