Melting battery posts 2024
BeardedBassGuy reply :
So today when I got back to the launch I noticed that the connectors from my tm to the battery were very hot. I looked it up and says bad connection, but that's not the question. You can see where the plastic actually started right above the date sticker melting and the whole connecting post actually looks that it got so hot it slightly started sinking into the plastic. I'm planning on picking up a new tm, but do you guys think the battery is still safe to use without being potentially dangerous seeing it has sulphuric acid in it. Thanks , Joe * tried to add pictures not working now will try later

That battery is toast. There is a bad connection, but it sounds like the internal connection is bad. A good amp draw from your TM could cause a fire.

Oh wow wouldn't want to cause a fire. Are you talking about the internal connection from the TM?
B-Dozer reply :
Could very well be just a bad connection at the battery. pull off the terminal, and check for corrosion. resistance is heat. I've seen the same on my TM to battery connection. remove, clean, reattached, go fishin' ????

**CORRECTION** ITS not the terminals but the post that you connect to tm to.

Hot/melting terminals is a short or dead cell in the battery.
Take the battery to your local auto parts store and ask them to do a load test on it. They’ll know quickly if the battery is toast.
If your battery passes start looking for a short, worn wire insulation, or a problem with your trolling motor.
If you have another known good battery, hook your TM to it and run it. If the terminals get hot quickly, you’ve found your problem.
Best of luck....

I was talking about the internal connection on the battery. If there was a problem with the TM, it probably would have melted wires/connections inside the TM.

Based on the date it's new so should be covered by warranty.

Hey @Arcs&sparks , is this a terminal gauge-size problem?
Log Catcher reply :
I absolutely would not trust that battery. There are too many things that can cause problems.

Yeah I couldn't either. I brought it back to Walmart where I bought it a few months ago and they exchanged it for me. Hopefully this one won't have that problem

Yeah I brought it back to Wally and they exchanged it no problem

I had the same problem with my Everstart the terminal post melted off.

Ive had a few melt plastic around corroded connections, a wire brush usually fixes it. Just hold your breath while brushing!

Do you have a fuse or circuit breaker connected in series near the battery?
WRB reply :
^^^^this^^^^^
You must have a 40 to 50 amp circuit breaker between the battery and TM.
jbrew73 reply :
Looks like a loose terminal connection caused the terminal to heat up and melt the spot on the battery. I doubt the battery caused the issue. I’d inspect the battery closely and test it. If it’s ok I’d use it. My concern would be the wiring or a trolling motor pulling too many amps.

Yeah that's what is is, an everstart.

The TM is connected right to the battery. Just a little 10 ft jon,
Wurming67 reply :
I won't buy another Everstart after seeing that

Yeah not sure if I would either. What did you get to replace that?

They exchanged it out for me at no charge but I'm keeping a close eye on it,I won't buy another one though.

Doesn't matter if it's 2ft or 20ft,. Any kind of high amperage malunction is a potential cause for fire

Do you have an inline fuse or circuit breaker between the TM and the battery? Preferably as close to the battery as possible. This is a must have, not optional. Alternative: fire.
If inline fuse clears or circuit breaker flips, there may be a short upstream towards (or in) the TM.
billu reply :
I agree with Dink above Looking at the photo that has nothing to do with the battery, it looks more like a loose connection, (wire in the terminal) as that's where the heat is shown. Things to check, make sure the terminal is the correct size and length for the amps of your trolling motor,make sure the terminal is crimped good . If you have a breaker or a fuse installed and its sized correctly it would have tripped the breaker or blew the fuse if the there was a short or if the wire is two small it would have melted before it would have tripped the breaker or blew the fuse. You need to cut the end off the wire and inspect if there is any sign of heat it needs to be cut out or the wire replace or your problem will still exist.

Everstart are good batteries. Made by Exide

I have no idea about the inline fuse or circuit breaker. What do they normally go for, and how do you install it?

The basic idea is that instead of connecting the device (trolling motor etc) directly to the battery, you want to insert a fuse that will break and cut off power before the cable overheats and catches fire. You just want to essentially cut the positive cable to (between battery and trolling motor) say a foot from the battery terminal, and insert a fuse between the two cut ends. Right in line, in series. Various ways to make the connections - solder them, crimp them, bolt them down, etc. Depends on the fuse housing. There are lots of different models out there. If you go to your marine shop and tell them you need an inline fuse to mount near the battery, that should be enough for them to steer you in the right direction.
You will need to the recommended fuse rating for your TM. You should be able to get this from your TM specs. Once you've put the appropriate fuse holder inline, just make sure you use the recommended fuse rating. If your TM says use a 20 amp fuse, don't use a 30 (cable could overheat).
Connecting any power hungry device directly to a battery without a fuse is Not Good. All fine until something goes wrong, and then it goes very wrong, very fast.
I'll dig up the info on the circuit breaker I installed for my TM. I just bought the breaker at my local marine shop - probably cost $30+ or so, and I just had to solder ring lugs on each of the cut cable ends (you could also just crim them), then bolted those ring logs to the circuit breaker, and installed the breaker through the sheet metal on the boat. I might have photos somewhere... will check.

Alright thanks, appreciate the answer I'll have to look into that.
