Last trip out i noticed one of my 24v battery banks for the trolling motor was acting up. I checked them out and all looked fine. So i figured I must have forgotten to hook them to the charger. So i hook them up to my onboard charger last night, get out on the water, and i got no juice. I open the battery compartment to find the top of the battery blown off! Im not sure what caused the issue.
As you can see by the manufacturer date (9/15) this is a pretty new battery. Especially considering that i didn't buy it till 4/2016. With only 6 months of use per year at the Quabbin, this thing has seen about a full year of use.
Ill be bringing it back to WalMart to see what they can do for me...
The scary part is, i have 3 more in the boat right now... :o

Good luck sir, that looks like a whole lot of bummer... at least you weren’t stranded anywhere.
-
Glad all is ok.
Would it possibly be a case of over charging? Faulty charger?
I have personally seen this happen to a over charged battery.

Still made by Johnson controls?? Had one internally short and die on me this year my self in my van?? bought it less then a year ago so they damaged swapped it out.. that was the nice thing.. mine was a max with 3 or 5 year full replacement warranty ...I was smelling hydrogen gas LIke cloreaen from a swimming pool smell and then it croaked a month or two later.. might have been internally shorted?? Funny thing is my old ranger my mothers car even have two batteries for the boat that are good?? and have been reliable the old batteries were made by Johnson controls questions is yours??

Also some newer battery chargers have different setting like slead lead acid/agm ,conventinal low maintenance ,and deep cycle.. each is a setting on my charger if you try charging a agm battery with the low maintenance charge circuit it could do the same or even deep cycle with a low maintenance setting. Might but not sure would have to look ..

I have a 2 bank onbaord charger from cabelas made by Pro Mariner. I bought them last year.
How can you tell if its over charging?

Make sure you wash down and rinse out the compartment well and rinse the bilge well.

Covered everything with baking soda, which neutralizes the acid, then scooped out what i could. Everything got a good rinse afterward.

Hope you got a fire extinguisher on borad too cause you said you got 3 more??

If replacing with a different battery how about optima ?? Twice the price $232.99 for the 75-25 model number.. that's just for one replace them as they go out? Here is a link to the battery at auto zone it has 3 yr warranty.. I belive there a sealed glass Matt type battery?? so use caution with your charger.. make sure it will work with it.. if you go with them had one going on 6 year before I sold it with the car a taurus it was in...the regular duralast batteries only have one year warranty and are around $95 so that from $232 Is what if you replace the battery every year?? Or so.. oh by the way is this in a low lying area of the boat were battery gasses could built up and maybe a arc blew it up?? It happens like on trickle chargers some time kick on and boom ...

This is what I get for searching deep cycle battery at autozone. I get a regular marine battery the battery should be this model at this price.. I don't think it's worth it unless you do?? 2yr warranty at $271.99 I would just buy the better wally world battery? I think those have 3 yr warranty not sure though been a while since I bought one..

i have that same battery.... i will have to watch out i guess....

I do have a fire extinguisher.
My trolling motor is 24v so i have 2x 12v batteries in series. I have 2 more 12v in series in the front for the trolling motor as well. This allows me to troll all day (8+ hrs) using the trolling motor.
I may look into the plastic housing you can drop your battery into, if it will fit into where i keep my battery
Edit.. Ordered two cases off amazon for 12$ each for the 27 Group Size. The smaller sizes are cheaper. I strongly suggest you guys get one for each of your batteries to contain the acid if there is a blow out.

Outstanding idea Will. I have also ruined a a couple pair of jeans from the battery acid moving batteries around for my Inverters I use for power back up of my basement fish tanks. Did some damage to the epoxy covered floor too.

Not sure on that. In my case the battery was on a emergency generator(the battery blew when the generator went to start I was 3 feet away) . The technician that came indicated a over charge of the battery.
Good idea with the battery box.

That's the other thing I forgot to suggest is a battery box.. to help contain the acid.. thought about it but forgot too.. . Also be carefull when charging cause the fumes are flamable that batteries let off they can pop when charged .. some time explode always good to air area out for a minute or three before you start chargeing... this will prevent explosions..

Interstate batteries is all I run, period. 2 on my CC and 2 on my bassboat. I also started off with the same wally world battery and it was absolutely trash. glad you and everything is ok but batteries are definitely important equipment. Its one thing i will never skimp on.
i see people do it with fishing line all the time as well. they have the best rods, reels, lures and buy the cheapest fishing line they can.... whats the point?!

I officially hate superslick. time to go maxcuatro

Also the new optima batteries suck. I wouldn't bother with them.

I'm not going to recommend a brand because everyone has their own opinion.. I will say this... always keep trolling motor batteries in an enclosed battery box.. it protects the battery...it protects your boat and in extreme cases like this..it can protect you... I mount the breaker on the side of the battery box to make a handy battery isolation switch...I've see batteries blow up from 2 things... over charging ( once by someone leaving the trolling motor down and running 9 miles... because a turning propeller on a trolling motor is an uncontrolled generator).. and from loose connections ( causing a spark in a newly charged battery)...the pro mariner is an excellent automatic charger... when a battery Is over charging the acid smell is over powering ..that is your first clue.

I would be careful buying anything at Walmart. Some of the name brand products are not the same product you get elsewhere. Reduced quality to reduce the price. Repeating myself but know of a case where a name brand fishing reel was brought in for repair. Part was ordered and wouldn't work for that reel. Turns out it was a slightly different version of a name brand reel (Zebco) to bring the cost down. Cheaper slightly different parts were used.
Also know of a guy that made anchors for Walmart. Price was agreed on for so many units and a contract was signed. When the units were delivered the vendor was handed a piece of paper that said, "This is what we are paying take it or leave it." (Lower price). Walmart has an army of lawyers and the guy did not so... Needless to say he never did business with them again.
Dirty place to do business with.

The areas i keep my batteries are well ventilated. They will be going into the vented boxes i posted above as well.
I have heard good and bad about the Wal Mart batteries, same with Interstate and the Optimas. This is the first issue i have had with one in the 4 years running them. So ill chalk it up to a bad battery. If it happens again, ill be looking to replace all of them.
-
The issue with batteries is this...its a couple very large manifacturers who make the majority and then white label or oem their stuff to be remarketed as optima, interstate, and so forth. Thus many times its the same manufacturer with a different label. If its flooded acid and you do not check the water level what happens to Will can happen to any of us. I also use a promariner...I have 2 2 bank jobs. The issue I suspect is it blew that battery during a conditioning cycle. Which is hugher voltage pumped specifically to clean deposites off the flooded plates. I can see how a dry battery would nuke during that cycle. That said ill be checking and adding distilled water to mine!

These are supposedly maintenance free.

I do have an optima for cranking when it craps out I’ll go back to a flooded one , the other 3 are flooded and I add distilled water every boating season to all three , I’ve seen dry batteries blow on heavy equipment
-
Got the new boxes in and was able to install one of them, they will be perfect for the two batteries under my left/right consoles. The two batteries in the back are contained in seperate side storage areas that are to small for the boxes, but thats ok since they are contained.

So i got out today with the new battery. Charged to full last night..
Got on the water, and the battery in the same bay as the one that had exploded was drained down to 8.5v..
The only thing hooked to these batteries is the trolling motor and the onboard charger. The trolling motor is not plugged in while not in use. So i unhooked the charger and used a portable charger to charge the battery to full. Hooked the trolling motor wire back up (trolling motor unplugged) and left the onboard charger disconnected. It held steady at 13.5v all afternoon. No parasitic draw going to the trolling motor from what i could tell.
I then hooked the onboard charger back up to it, with no power plugged in. After an hour the battery had dropped 2 full volts to about 11.5..
I dont know how or why, but the onboard charger is sucking juice from that battery when not plugged into power... Im guessing that when plugged into power, the constant charger to full/shut off, then discharge, then charge again cycle is what caused the battery to blow.
They have a 2yr warranty at Cabelas. I got it in Feb of 2017 so im still good. Now the question is, do i return both of them to protect myself from the other charger from failing?
-
I would .. cause it sounds like the circuit is back feeding some how in the charger but like you said it's under warranty.. at that point i would return every thing you bought if one or two chargers return them.. my question is this charge a 24v charger or a 12volt charger??

Its a 12/24v charger. But has leads that goes to each of the two 12v batteries and charges them separately.
-
I would give ProMariner a call and see what they have to say. They have great customer service (at least they did when I was the Customer Service Manager)...

Cabelas swapped them out (for a newer model no less) as they were under warranty. Ill get them installed and do some more testing.

Just make sure they don't revert back to 12 volt mode when off.. check it's in 24volt some of today's digital crap does this.. 24 volts is enough to fry the 12 volt circuits and cause it to back feed threw the circuit..
