Deep Cycle Battery Mistake, Marine and Dual Purpose - Which to Use

Common Deep Cycle Battery Mistakes
Years ago, I mean years and years ago, a common mistake in purchasing a marine battery (for a boat under 25’) was to chose a deep cycle battery because it was thought that it would hold a charge longer when out on the water.
The problem is that deep cycle batteries are engineered to deliver a steady flow of electricity over a long period of time. Supplying things like lights, radio or an electric frig that draw low constant amounts of electricity. They tend to not deliver the gross amount of amperage all at once compared to a standard ‘Marine Starting’ battery although technology has improved this issue.
The ‘Starting Battery’ is engineered to deliver lots of amperage all at once rather than a little at a time over a longer period. They could also be damaged if drawn down to zero power as opposed to a deep cycle that can usually handle that issue.
The ‘Dual Purpose’ battery in the video is a perfect example of what technology has provided. It can deliver a constant draw of power and yet maintain enough juice to crank over and start an engine. However if one uses too much of that battery there might not be enough left to start the boat.
My solution is to have 2 Dual Purpose batteries on my pontoon boat with a switch to select either battery or both. I always run on battery ‘1’ or ‘2’ alternating between boating days. That way I know both batteries are good because each one gets a chance to start the boat on its own. Plus each one gets charged separately fully on ‘its’ day.
In the past I’ve had 2 batteries charging at once only to find a bad battery took most of the charge leaving the good battery not being charged properly. Running each one separately provides constant proof that it is in good condition.

Unfortunately this video is incorrect on many levels.. his information on both batteries is not accurate. Deep cycle are meant to draw power for long periods of time but NEVER draw ANY battery to zero. That dual purpose battery does cranking and deep cycle on a medium level but neither extremely well, he kept talking about the dual as cranking only battery..

For marine purposes, get an odyssey extreme (formerly northstar). They have more energy in them than other lead acid batteries in the same group size. They also have the most lead and are the heaviest in a group size you will find.

Hi there, Never fully discharge a deep cycle lead acid battery! The deeper you discharge the battery the more it will reduce the battery's total cycle life.

Thank you very much for your video it was short but you got straight to the point that I wanted to know and once again a big thank you for your video Australia said that .😊

Dual purpose and cranking batteries are different, in this video you talked about cranking battery vs deep cycle

NEVER. EVER. Discharge ANY Batteries down to ZERO. ESPECIALLY ANY LEAD ACID types. Deep Cycle should be discharged to about 50% for maximum battery life cycles.

Can i use my car battery charger to charge my deep cycle battery for my Trolling motor for my Canoe????

This guy as no idea what he’s talking about. Never run any LA or AGM battery down past 50%.
They won’t last too long.

There's so many things wrong with this video You need to watch a YouTube video from somebody who really knows. Then remake this one. Deep cycle batteries cannot be rundown past 50%. Dual purpose batteries is simply a deep cycle hybrid that has enough power to start your outboard motor then it'll act as a deep cycle but not as long as a regular deep cycle. Please either fix this video or take it down You're misleading.

If deep cycle batteries are better than why don't they just use them for All cars? And are they the best ones to use to power your house

So will the deep cycle start the car . I don't have to run it down a little ...but if I do it won't hurt it. so then would be a better option . If it can start the car.

Deep cycle batteries should be discharged to about 20% and no lower. They shouldn't be given a "Top off charge". If you don't have a gauge or other way of knowing, cables getting warm or motors and other components running sluggish are indicators of need to charge. Running the battery lower not only damages the battery, it heats and damages the component it's running.

Run down to 20%, then FULLY charge. Check water level after several charges and fill AFTER charging, never before. Only cover the plates, never add extra water.

If the battery sits for too long without being used, it should be checked and possibly charged.
