    What type of 12 volt battery is used in T? She is 2 years old, she was discharged to 6 volts. From the top opened the lid - inside is dry! So it should be or not? How to properly recharge it? Do you need to add distilled water to it or not?

    The battery is a sealed AGM. Not openable (not without destroying it, anyway). You can't add water.

    He was discharged for a long time. Is it dangerous for him or not? As far as I know, if the charge falls below 10.5V - this battery loses its capacity. If it repeats several times or long - it will break.
