Marine Battery Burnout and Replacement 

Hah I would have spent the entire afternoon attempting to lift that bow thruster battery out of the box in that little area. Seeing what you did just sliding the whole box out is why I hate working on them sometimes. Someone always knows an easier way, and you just showed me. Thank you :)

Hello cap. Mine are almost 5 years too i think is time for mine to be change too Thanks for the video

I had done this back Oct 23. on my 07' 341. The bats were Interstate commercial batteries, about 9 years old. I had to order current interstate model M-31HSC. $149 ech. Came next day to my local dealer. 1000CCA, 1250 Cranking, 180 minutes reserve, 99Ah. They're actually not marine, but Heavy Duty for long haul trucks with reefers, and sleeper cabs. I also noticed your existing bats were only single screw stud, which is what these are. These also are Maintenance FREE. I hope we both get 7-9 years of service. THANKS for everything you post!

Love the videos you sound exactly like Al Michaels.😮

5 Years is really good service. I use to use AC-Delco maintenance free batteries in the 90's and would get 5-6 years of service.

Thanks for the detailed instruction. Getting ready to replace all 6 batteries on our 08 341NSB this coming weekend. My concern was how to get out/in the bow thruster battery in that tighter spot.

another great video enjoy watching them thanks Tom alk in Michigan

I noticed that Duracell battery had the D6 date code sticker on it meaning it was from April 2016 so you got a little more than eight years out of that one. Definitely time to replace it.

Man thats great advice on battery maintenance. Thanks for sharing. I need to do a lot betther job on batteries.

The two batteries in my boat are coming up on 10 years old and seem to still be going strong! I keep thinking they'll fail me soon, but we'll see. Hopefully you got the batteries on sale, I think I saw WM had 25% off the other week.

5 years old... They were done

Love your channel. I own a 26 express & need to change batteries for first time. No gen. What batteries do you recommend?

Second hand electrical problems from Reel Joy next door... 🙂

I got 3 of those same west marine batteries for house bank, 2 group 31 duracells for cranking the diesels

You're lucky you have small batteries. I have twin Cummins and I have a westebeke diesel generator also. So I have 3 8D batteries. Heavy as hell. Both bow and stern thrusters have 2 batteries each to get the 24 volt the thrusters need....

Maintenance on the boat seems to cost more than the boat itself

That misaligned knob is really stressing me out.

You see pretty good with current technology. Have you considered a solar array and lithium-ion house setup? Just helping ya spend buck$! If installed properly, it’ll serve you for years.

i replace mine every 5 years no matter what

BTW, what did you find when you made it back to the house and got under the boat to see if there was any damage or paint missing when you hit the shoal?

A nit-a millennium is 1,000 years; a century is 100. Still, we all know what you meant.

Good move batteries usually last about 7 years but in Florida yea your risking it 5 tops would you consider lithium in the future ?
