Replaced battery after 2-3 years usage since used up. It run well for a short drive, then when I had a long drive in countryside for firts time battery started to heat and acid vapors generated, with the baterry leaking form bottom and after 3 hours car came to stop with major electrical failure affetcting alternator. ABS, Central locking, wipers etc. The car was running perfect before except difficult to start so battery replaced. Can this type of battery failure cause this major breakdown? Previous battery exactlt same model run perfectly for years. Am struggling with battery manufacturer to pay repair or car scrap residual value as repair is over 3000 euros.
A nesw battery installation coincide exactly in time with the major failure, statistcally is alsmos inpossible that the system failed causing the new component (battery) to fail.

The alternator is overcharging the battery and could explode at any time-get it checked out

Thx for your reply but, it is almost impossible that at exactly at THE SAME time that battery is replaced tha alternator start to fail. One new faulty component got all the chances to cause a catastropy like this. A system dont just fail simoultameously as it was working peferctly with old battery. A system failing exactly at same time that a new component is installed is statistically a very very remote possibility. So is is possible this type of catastrophy caused by a faulty battery? Battery was analized and found witb one of the 5 vases almost empty and much lowwer voltage than others (less than half) battery had a local failure wich could cause a short circuit. Can any one help?

If you load test the battery for 10 secs and won't hold 9.6 volts or higher send it to the recycling center and get a new one

Thx I changed the battery but the car is in Mitsubishy repair shop with lots of electronic components damaged, the alternator, the ABS system, the SRS, the wipers, the central locking. This battery installation casued a disaster and the car was perfectly before. The battery investigation after teardown found 2 vases almost empty and leakinf at the bottom. Can the faulty battery cause this disaster if has a quality defect of this nature at purchase? The alternator and other components damage might be caused by faulty new battery?
