“I google stuff.” -Roland Martin 😂😂😂

good video, thanks. FYI: AGM stands for absorbent glass mat.

Thanks for the info Mr Martin. Been a fan for 25+ years and your still teaching me stuff.

Great video Roland. Good to see you again. Thanks

Great stuff getting ready to buy now I know what to get, thanks Roland

This guy's is a classic

Thank you very helpful, alot of good information.

good stuff Roland i do appreciate the info

Perfect! God Bless you Roland!

Very helpful information. Thank you from Alaska. 🇺🇸👊

Mr Martin you are still the man!!

Your knowledge is pretty solid. Thank you for your information. The self discharge information being more and less on some battery types will help me a lot.

Great information !!

SON YOUR THE BEST

WELL SAID THANK YOU

Great information sir.

good stuff Roland

I really liked reading your book

Great info keep these vids coming and maybe BOAT want stand for "bust out another thousand" anymore.

Great video

Absolutely. I just got a used boat and it had an older (2013) marine starting battery. I replaced that battery with a deep cycle which actually has more cranking amps than the old one. Definitely agree with livewell pumps running, boat lights, gauges or any other accessory, deep cycle is the way to go provided you get one big enough. Electronic fuel injection and the computer on the boat engine requires in some instances a certain amp size battery so make sure you get one big enough to satisfy those requirements. During idle times (winter and the heat of the summer) when I'm not fishing I don't disconnect my batteries but make sure I give them a regular charge. I have an onboard charger for the two trolling motor batteries and use a small 2 amp charger to top off the start battery( which again is a deep cycle). I have a regular schedule of running all my small engines that are idle (leaf blower, chainsaw, generator etc) and I keep up with the dates on a dry erase board I keep out in my storage building. Roland , Sir another excellent video! Always a joy to watch you and Scott's videos!!! And btw yes google will help you solve a lot of questions. Just today , I had the mouse cursor kept freezing up on my desktop. Googled and found something as simple as trying another usb port to plug the dongle into made it work perfectly again....

This video was such an awesome example of knowledge that I’d truly like to hear from such a seasoned fishing veteran. Great job guys. I really learned a lot from this video and I’ve taken so many credits of chemistry and physics classes in the past where battery questions were half of the exams. Batteries are just a good example for understanding a lot. But studied knowledge from a book is a lot different than learned knowledge applied and taught in the real world. Any other vids like this from the O.G. Roland Martin would benefit a lot of people. Edit* Including me!

INFORMATIVE - I FOUND OUT THINGS I DID NOT KNOW

I learned something from this. I didnt know AGM charged 5 times faster. Ive been running them for many years on the boat and truck. Ive gone thru many over the years

lots of good no shit info on batteries from a legend! I actually run the same cranking battery in my rig!

My OMC mechanic told me not to use a marine battery for starting the outboard. He said it can mess up the electronics over time.

nice vid. bilge pump will also drain your battery too if left connected

Very good information Roland!! I learned trickle charging from my buddy who has a few classic cars. It keeps it topped off without burning it. I use this method on the riding lawn mower too and it is great for just about any type of battery that is not used on a regular basis. Thank you for sharing this!!

Wow I'm glad I just bought a new agm

Roland what kind of batteries are you using for your trolling motor?

👍

I always hear that when tying 2 or more batteries together (series not parallel) that they should be same specs. I don't truly understand how it makes a difference unless the charging amperage output from motor/charger is too low. Do NY of you couple different sized batteries together with or without isolation or switching?

When you look at deep cycle marine batteries... I wanted to ask you what the volts should look like when they are new? By this I mean I'm trying to look at if this can be indicative of if the battery is bad or good quality. With new batteries some people are saying they will be not just 12.5 volts but actually over 13 volts. And this has me curious. Should a new battery actually be closer to 13 V or more? And can this really be used to tell if its a really good battery or not on when they are new if that voltage is a bit higher than just a default 12.5 Volts? And if its lower on new do you think that means they are refurbished parts or refurbished batteries reboxed as a new one? I'd recently got some new marine batteries, and they haven't been used but don't go above 12.5 Volts. And I keep hearing people saying their new batteries are getting 13. ... Thank you. I'm curious what you might say on this or others particularly for higher amp hour batteries. (Although I'm using them not for boats but solar battery banks.) IF AGM batteries recharge quicker than others, and have less self discharge loss... in a battery bank it would suggest that if you had more than one type of battery you would probably want the AGM battery as the lead battery where the incoming power flow is with it connected to the bus that goes into the other batteries for both efficiency and better performance.

Be very careful about adding a deep cycle battery as a cranking battery. Some motors, the mercury OptiMaxx for example, explicitly say to never use a deep cycle battery as it will void your warranty.

For deep cycle batteries you need a charger that will shut off after its fully charged then turn back on to charge it to its max if it loses any charge. Lots of trickle chargers are constant volts and can lower the life of the battery if left on until the next battery use which tons of people do. A cheap trickle charger will ruin a fully charged battery if you leave it on for weeks at a time, you might not notice its damaged but it will lower the lifespan. Charge the battery the day before you go out don't trickle charge it. If you are not going to use the battery every year get a smart charger that shuts off then on not a trickle charger.

AGM stands for absorbed glass mat

Hey make a fishing video on the Suwannee river

Son I said SON. Remember your fishin shows years ago.

What about lithium vs amg

Does batteries cause electrolises on aluminum boats had a bass tracker that got ate up with it years ago was wondering if that was the cause .i left batteries always hooked up in it .

I prefer ACDelco Batteries. Better warranty.

How about Lithium ??

you can disconect the ground this will make the battery not discharge

what kind of battery do you recommend for electronics?

Cell phone comparison is silly. Cell phones constantly register with the nearest tower.

Dolan Morgan

Clean your battery son!!!

Did you take the advice of the most intelligent VP ever "Kamala Harris" and Googled stuff?
