Marine battery tie downs...necessary?
Posted on 4/27/20 at 3:13 pm
Posted on 4/27/20 at 3:13 pm
OB, I have 4 batteries in my bay boat. Two cranking and two deep cycle. All are in battery trays which are secure to the floor. Last year I replaced all the straps which secure them to the tray and they are all broken already. Not snapped, just disintegrated. Maybe due to moisture. Question is, if the batteries are in the trays, is it necessary to strap them down?

My battery compartment is tight, and the leads hooked up to them pretty much hold them in place. my straps all dry rotted years ago. Never replaced them.

I was asking a question looking for honest advice from experienced outdoorsmen. I don’t appreciate your smart arse response cool guy. Take that crap to the OT.

Well I do have 21 gallons of gas in a plastic container in there with them
. Honestly I probably should put some tie downs but they fit snug in the trays and will hit something front and back before getting to the tip over point. If the force needed to lift them and flip them ever occurs then that means I've got bigger problems on my hands than a flipped battery.

Remember when your parents told you it you don't have anything nice to say .

Yes OP. Vibration can break down a battery. Buy some long Zip ties. Ones that are used for AC duct work to tie them down.

I prefer having everything on a boat ship shape and Bristol fashion but that being said it depends on what kind of boating you do. Lakes and smaller rivers with little or no commercial traffic? Probably not an issue. Offshore runs of 100 plus miles???? Absolutely, everything has a place and everything in its place....there is too little room for error offshore and the difference is between an inconvenience to one of life and death. I wouldn't depend on a web strap to keep batteries in place on an offshore boat.....I'd have an aluminum tray coated in rubber with a similar bar holding the batteries in place.....entirety needs to be in a ventilated space where fuel fumes aren't a possibility...with proper wiring and grease (dielectric) protected when shrink wrapping and grease isn't an option. I have crossed gulf stream several hundred times alone back when I was young and dumb....I have been in situations in a boat offshore, alone, that still make me cringe.....one of the reasons I am still here is because of insisting on things being proper on a hunk of fiberglass and styofoam between me and the deep blue sea...

make sure they are covered at least....even a little chop will cause hardware to start wondering around the hull of a boat....the damned things migrate, who knew? If one falls odds are that, even though the area it would be a problem is minscule compared to the area it could fall they are devishly set on ending their lives above water and do not mind takin you with them....that's why they are called "screws" by some....'cause they will screw you if they get half a chance....

Vibration is also the achilles heel of any wire termination, especially mechanical connections, but also works on crimped connections....and loose connections are bad juju....at best your batteries won't last as long and your charge won't either...worse case scenario is heat and arcing....thigs get real exciting then....especially if you are sitting straddle of the battery and running the tiller!!!! That shite'll get your attention right fast.....

if the straps are breaking down that quick you may have a battery problem, especially if they are wet cell batteries....the off gasing of a batteries gets worse with age and it is very corrosive when combined with sunlight effects on nylon.

I would says yes, I had a battery terminal bend about 45 degree on a battery that was just in a tray and not tied down. My cable was a little short which could have contributed. It did ruin my battery

This - tie them down to keep the connections from coming loose or breaking.

Used to have the same issues. Swapped to these trays and have been fine since. LINK

OP, I had a battery come out a tray and break off a livewell pump. Stopped to fish, 10 mins later I have water coming up thru the floor drain. 
This was in a bass boat.

Any issue with having my gas tank near my batteries in a completely open storage area?
This is behind my rear beanch, and it is always open.
Fumes shouldn't be an issue like this, huh?

Nylon straps are generally not gonna rot.
Plain stupid if you dont strap them down......
