battery

I have a 2019 Sea Ray 280 SLX that I purchased new last year. When I drop anchor, turn off the boat and listen to music for several hours my battery runs down to the point where I almost don’t have the power to start the engine or raise the anchor. Is this normal? The boat has two batteries and...

I own a 2017 SeaRay 260 and having an battery or electrical issue. It started out as a possible bad battery after winter storage. When Battery Control Knob were set to #1 position, and key turned half-way (engine start not attempted), the console gauges were not working. I thought - ok...

Howdy, New to the forum. Just got a 1994 200 Signature and it has a single battery setup. The boat is going to be stored on a trailer at a storage facility when not in use. Would it be better to take the battery home after each use and charge? Better to just leave it on the boat and bring a...

Hi all, looking to purchase a 260 or 280 sundancer and since this will be my first time owning a cruiser i'm curious about some simple things. (Excuse my naivety here, but i am a newbie to these boats so any info surely helps.) Generally speaking i know these boats are equipped with a microwave...

A little history. I put my boat in the water, turned the key, nothing... Just a faint click from engine compartment. So I wiggle the shifter to ensure it's in neutral, try to start again, nothing. I checked battery connections, they are tight, try ignition again, the boat fires up and runs...

Afternoon - I have a '99 340 DA, just had my batteries tested. Accessory batteries came up 57 and 63 CCA and the voltage was below 12 volts. I assume they are group 27 based on the size. Any idea what CCA or MCA I need? I know I don't need starting batteries, should I get the dual batteries...

Hello, I have a 2002 Westerbeke Gas Genny with around 100 hours. I just purchased boat last season and it had only 60 hours on it. The issue I'm having is the generator runs fine but after about an hour it dies, and wont start back up due to dead battery. I had battery tested and its...

Good morning, It's just about that time. In the salon I have my electrical panel. In the panel I have 2 DC Volt Meters for the 2 auxiliary batteries (not the starting batteries). The one meter isn't working. Anyone have this problem? I would assume it's a connection issue. Where would you...

So I bought this boat last year and did a complete rebuild on both engines. She had two deep cycle battery's and one cranking battery connected. I replaced all 3 batteries but now I am a little confused and I'm thinking maybe someone screwed something up in her previous life. From what I have...

I have two Deka multi-purpose batteries that have been used for two seasons. During the offseason I keep them in the garage and charge with a tender about once a month. One battery charges to 14.0 and the other tops out at 13.5. Should I be concerned? Would like to get one more season out of...

60 days till boating season !!! I have plugged in my 99 340 DA to charge the batteries. I plugged the boat in as if I was plugging in to shore power - the only difference is I plugged in to a regular 110v circuit. My question is - in the galley is my control panel. I have two rocker switches...

I have this boat. Need to replace the batteries but not sure if it's a 24 or 27. It's an hour drive to my boat, so I need some help. I searched the forum but couldn't find anything. I also checked the owners manual to no avail. I'm looking at the interstate ones here...

This will be the first time I'm having to replace my batteries on my 2002 sundancer 280. I believe I need to replace 2 starting batteries as one will not turn its engine over at all and the other one barely holds a charge. We barely got the boat started from anchor yesterday after only being...

Hello everyone, The beginning of the summer I purchased my first boat a 2005 - 340 Sundancer!! I have grown up around boats all my life, however this is my first! I've had a great time all summer with it and all is well! Except for the last 2 weekends, which leads me to my...

Lithium Marine BatteriesAnybody using Lithium Ion Marine Batteries? I need to replace two of my three batteries. So I Google searched on Super more better marine battery and among other stuff I found the information I copied and pasted below about Lithium Ion Marine Batteries. they say they...

I have a 2000 Sea Ray Sundancer 290 with twin engines and a generator. It has three batteries in the boat. When I stay at the beach over night the left engine doesn't have enough battery power to start. Also that same battery powers the windlass so if i use emergency power to start the left...

Need some battery advice. When I start my engines the starboard batteries only read approx 13 Volts on the gauge on the instrument panel while the port batteries immediately read 14+ volts. It also appears the starboard engine is slower to start but eventually turns over. This is after the...

Hi guys! Hoping you can help diagnose the drain on house battery (0.8A) when everything was switched off. Everything functions normally (which is hot wired to the battery - such as bilge/mercathode etc). I came across a similar thread which suspected the Alternator, so I tested the wire loom...

I have owned this new to us Sea Ray for a little over a month now. To date, new cockpit carpets ordered plus a new port side sun pad to go with the centreline one and other custom starboard cushion. We've spent a whack of time cleaning, getting ready for the weather to break here in the...
