Check the liquid level inside the battery. It could be very low.
Also check the alternator output. If you are overcharging the batteries that can overheat them and cook them pretty fast.
This is also incredibly dangerous. You really don't want a battery to explode in your face!!!!

It's hard to tell, cuz the OP doesn't have a sig or any information. But I concur.

disconnect the suspect battery and measure the voltage cold after filling with distilled water, if low. it should be 12.2 to 12.8 volts. If it's low connect to a slow charger 2-3 amps. If it doesn't charge the battery is bad and you have shorted cells that caused the boiling. THat can be a very dangerous and potentially explosive.
First check alternator / regulator output voltage when running that can overcharge the battery and kill it. even if one battery is still good. The question is also is this an older model with a separate regulator or is the regulator built into the alternator.
You mentioned a light was out? Could there have been a short causing a problem with the light out and the battery boiling? check the wires around the battery and headlight?

If they are badly mismatched. Electrically they are connected so to make a single larger battery. One may be hogging all the current.

If there is a bad cell, then that will hog all the juice and the good battery will never charge. eventually, that dead cell can kill a good battery connected to it since the bad battery will pull the voltage down from the good battery.
The solution is pull both batteries and individually trickle charge them. Once done and resting several hours, check the voltage on both batteries. they should be the same. If they are .2 volts apart or more then they are not matched. THey should both read around 12.8 Volts.

Yes yes it was a dead battery I replaced both and things are good not sure if I mentioned it or not but I also put new belt cause it's old and was slipppng on the power steering the truck is running good I still have a glow plug issue but it is warm out sucks I have to plug it in but that comes in two or so weeks and it's my weekend truck so it works
