Battery releases liquid?

We took a battery to Autozone after accidentally leaving the lights on for about an hour. The guy that checked the battery said yes it needs a charge. The next day we go and a different employee said it's showing good and 81 per cent and by driving it you can get it up to 100 per cent or we can charge it for another hour. I left it for another hour. Then when picking it up a third different employee said it was a bad battery thought it showed 100 per cent. (?) And that was liquid on top of the battery. Is that nothing but water and we can it filled? So three different employees and not all three comments matched.

    The clerks were guessing. You're gambling. If the battery is 4 years old or more it's inching toward the end of usefulness. You can refill a battery with distilled water and water is what came out during charging. Do NOT use tap or filtered water which is probably chlorinated and will kill what's left of the battery. Put your battery back in the car and go your merry way, trusting your alternator to keep doing its job, unless the charge warning light comes on. You could have the alternator checked just to be thorough. You know what ran the battery down was you leaving the lights on. A battery that runs down by itself or fails to charge needs replacing.

    That battery acid that boiled out.

    Just top up the battery with distilled water.

    Auto Zone has a battery tester. Does it show the battery is bad?

    Time to get your battery to a real mechanic. Autozone does not have them. They are a car parts store with staff pretending to be mechanics.

    tell them the conflicting stories you are getting. See what they say. Listen carefully to what they say.

    Most modern batteries are a closed system and do not need refilling so the water may be condensation if the battery froze up.
