Any one know what can cause a battery to boil and leak. I just bought a brand new battery expensive to at 100 and its leaking and boiling. Bought it from autozone and im about headed back there. Why would the fluid boil. Maybe shes getting over charged. The fellow at autozone said the alternater i bought from them has a built in voltage regulator. maybe its faulty
Take the alternator down and have it tested...chances are it is overcharging and causing the problem with the battery.
I wasn''t causeing problems with the old battery which make me feel like the problem is with the new battery
What is your volt meter reading? Should be between 13.8 & 14.2v. Any more than that will boil your battery. I take it youre running a 1 wire alt, so you have a 12ga min. wire running from the alt lug to the starter, correct? Only other thing that will cause a batt. to boil is a shorted plate. If you have that, your batt will go dead just sitting there unused.
If the old battery was weak it wouldn't be overcharged...the new battery is fully charged and with it overcharging...it boils over. Be safe and have them both tested, battery and alt.
MINK...It sounds to me like the new battery has a short in it. O YEA even new batterys can be bad. what have they got to lose at the auto parts. well maby a customer if they don't work with you...POP.
Exactly. Also ambient temp outside of the battery shouldn't be over 120* F. It will also boil the water out.
Hey guy measure 16 volts at the baterry when running at a certain rpm and as rpm increased voltage increase. So its got to be the alternator wiring or the alternator. I bought the alternator from Autozone specifical made sure it was an internally regulated alternator. Two wires come from alternator and i grounded the alternator housing to engine. Those two wire are Red and white( 16 gauge-->smaller diam). Red connected 3 inch lead was crimped with a circlular connector and then connected to the red post on the alternator. Also on that post is connected a 10 gauge wire directly to the battery pos + . The white 16 gauge wire connected to the coil with diode inline. I know the white connection is right because the car shut off when i need it to. But if all else is right then Im not sure. Faulty built in Voltage Regulator??
Rule #1: when purchasing parts from FLAPS stores,,, if it has more than one moving part, get it somewhere else. Having been on the recieving end of 3 bad out of the box autozone alternators I would make sure they test the new one before I paid for it.
This situation brings me to a thought. Can you run an extra external regulator in line for backup? I'd rather do that than blow a battery up.
Batteries generally have to be up around 19-20 volts to boil like that, but have the battery checked or go somewhere they can drop a test battery in the car and check it in a running state. That's what I used to do in one shop where I worked. AZ may not make good on the battery if you show them a charging system component problem. Unless its still under warranty. Heck, go back to AZ with the alternator and battery and have them both checked since you got them there. Bob
Did you replace the ground cable on the battery? check the connection to the frame or the block if it is loose or dirty, it can cause the battery to boil. Carlg
saw that happen once...guys were testing spark (spark tester) and grounded it smack up against a venting battery. KAAABLAMO, acid everywhere...luckily it missed everyones eyes. like mentioned before..triple check the batt n charging system.
Not entirely wrong, old dirty battery plates on the inside can cause a similar condition. When you put in the new clean battery without all the funk on the inside it has a better chance at 100% charging power. It's just like a bad ground or corroded terminals. Electricity likes a clean contact no matter where it's at. I would still have the Alternator tested beacause it is definantly overcharging if your battery doesn't die overnight due to an internal short. Tim
