Overcharging

https://itstillruns.com/happens-overcharge-car-battery-5137116.html

Hi Figarou,

Yes...I thought of this and the mixture of my AGM deep cycle batteries and the flood cell engine batteries, but the batteries are over 5 years old and were just fine until very recently. I checked the charging parameters and nothing has changed. Gotta ponder this one a bit as the Xantrex smart charger might be getting old at 17 years old... SUM TING WONG.

Best,
Phil

Wait...are you mixing batteries?

As in different batteries hooked up together?

I've learned you can't have that. All needs to be the same. Brand, voltage and amps. A battery that's stronger than another can "charge" the weaker one.

Hi Folks,

I had an experience today on my Diesel Pusher RV before which I have never experienced.. I check the RV frequently for electrical health via several monitors and there have always been Green Lights for normal system functionality. So decided to pull it out and give it a sponge bath today. It would not start...It has two Group 31S batteries. So I accessed the engine start batteries to see what might be going on with these batteries... As far as I could tell, things were just fine..

Here is a picture of one of the batteries as I removed both in my investigation of a no start condition of the CAT Diesel...

Any folks see where the problem might be??????

Baffled in Green Valley (not!),

whew good thing you keep up with checking on the rv. that could have gone badly. hopefully not too much mess.

Nothing a little Red Green duct tape won't fix.

i watched a rerun of that late last night, it was much more cheesy than i remember..

Hi KJ,

Yep...Ranger chased to O'Riley AutoParts as they had 4 31S in stock...$400... Not too bad to install except for the weigh lifting into the compartment and cleaning up the mess from the shorted battery ....

Fired up the coach and it purred just fine...all is well again....so now I do not trust the battery health monitors at all. I have never had a battery do this before... Gotta be an internal short and thank goodness it did not cause a fire.... I think I will replace these new batteries in short order next year with good quality AGM batteries.

Best,

Looks like the battery froze. I’ve seen it a few times. Also if using wet cell and AGM or gel all 3 have different charging rates.

Lithium ion battery is another type.

Still, it's best not to mix these.

Hmmmm. The terminals are clean. Can't quite figure it out.

Hi Jim,

Battery never Froze...it was in the garage at my house...always above freezing...I think my Xantrex charger/inverter malfunctioned and overcharged the battery.... JMO...

Hi Figarou,

complex charging system Bi directiona "bird" charging system. It has worked fine for 17 years until now. Gotta figure out what went south....

Phil, Dave @AzScorpion was telling me that DeeZee makes a great RV battery. You may want to check into that.

BTW, when I saw that battery I though how lucky you were that it didn't cause a serious problem. As the old saying goes, "I'd rather have luck than a license to steal". And thankfully you were quite lucky.

Looks like the battery was bulging before it busted. Overcharging is my guess. Have seen plenty of overcharging battery issues, and they bulge before they finally bust open.

I think Dave would say a little 303 on the battery beforehand would have prevented that.

Well , I'm not here to start anything, but that battery looks terminal, who's in charge of your battery maintenance? I'm positive he should be fired or you will have more negative outcomes...
(Start , terminal ,charge,positive ,negative, and fire ...ehhh)
Maybe Tito is chewing up your wiring ? Damn tortoise... ?

Now you guys are finally learning! A little 303 Graphene Nano spray would've prevented all of this. ?
