    Add a battery

    I'm wondering if there would be an issue with running an AGM battery in parallel with and regular marine Interstate battery?

    Sweet. My starting battery is an Interstate Marine, and I have a Costco membership.

    Last question: Can someone recommend a deep cycle battery that I can use as my house battery?

    Faulty? Maybe. I still haven't heard from anyone who utilizes the Add-A-Battery kit that reports problems with the functionality.

    My boating needs are pretty much like this: Leave house in the morning, go skiing & tubing for a couple hours, anchor up in a cove eat lunch and crank the tunes. Hang out for a few more hours, and go home. I'm pretty sure I'll never run my house battery dead. If that's the case, my start battery will have been isolated from it anyways. I don't go on cruises, don't have a fridge, don't have much house battery demand.

    Wow, this thread grew some legs and took off! I guess my last question is this: Does it matter if I get a house battery that isn't the same CCA's as my start battery? I want to go with a deep cycle marine battery to run my electronics when the engine is off. Seems like the name "Add-A-Battery" implies that you can add what you want.

    The fuse I pictured connects right at the terminal, so battery cable length is unchanged. I'm happy to spend the money to ensure the system functions like the manufacture intends. Short cuts will only cause problems.

    What I don't want to do is lift the engine hatch every time I need switch between house and start batteries. My friend who has to do that hates it. This system is pretty straight forward: Turn the batteries on when you leave, off when you get home. Done.

    That's right. My boat only has 1 battery at the moment.

    The Add-A-Battery Kit has been around for about 10 years. Despite my efforts to find negative reviews of the product, I can't. I think I'm going to go this route unless someone with the system convinces me otherwise.

    I've heard the same about adding a second battery and keeping it isolated and not charged in parallel. I'm wondering if anyone has used the add a battery kit and had issues? Seems like a company like Blue Seas would put in the R&D to figure out how to make this work.

    After reading up in my trusty Mercruiser manuals, I found the amp produced by the 5.0 alternator. Looks like it produces 72 amps when cold, and 65 when hot. I didn't know amperage varied based on temp. Does this mean a 75 amp fuse will be sufficient for the cable running between the positive terminal and the ACR?

    Winter is driving me nuts and all I think about is getting the boat on the water. I've got a 2003 Sunesta 243, that's only got 1 battery. I'm going to add a battery and have looked into getting the Blue Seas Systems Add A Battery. That set up uses a switch and an ACR. After reading up, it looks like I need a fuse on each positive terminals of both batteries to run a battery cable to the ACR. My boat runs a 5.0 Mercruiser, and utilizes 2 awg wire from the engine to the battery. I'm wondering how big of fuse do I need? I thought 100 amp, but now I'm not sure. Thinking that might be too much.

    2 alarm beeps every minute: Updated Update...

    My mechanic friend diagnosed it as a faulty water pressure sensor. He also recommended that I replace the distributor cap and wheel. So, $160 later I've ordered the parts. We'll see if this fixes it, but I won't find out till next Spring since I winterized the boat this weekend. Till then... stay warm!
