Battery acid filling and charging may vary from battery to battery.

The only way in which this battery can be brought to life is by acid filling first. 45-53% topup. Close caps and shake the acid first inside the battery now open caps or valves.

Then charge the battery with greater voltage while keeping the caps opened for atleast 2hrs not more.

Say this is 4v battery and a normal charger voltage will be 4.75vdc.
Use 5.7vdc to 6vdc charger you can use buck converter to step down voltage to the same.

After 2 hrs battery will become warm.
Now disconnect the boosted charger close the valves finally put the safety cap now charge the battery.
Now you got a recovered battery
60-70% chance battery will be recovered if not left dry for long. Else it may damage.

*distilled water will never under go good electrolysis as it lack minerals. Try to light bulb by keeping two terminal dipped in distilled water and their wires apart will know the truth weather distilled water works or not?

**acid will make electrolysis try doing with battery acid don't try to do with normal lemon acid or bathroom acid may or maynot work.
***shaking the battery make remaining dirt dissolve.
****high voltage will undergo desulfation and will heat plates and acid which will make space for more electrons. High voltage for long may melt plate contacts.

灌水而已 幹嘛剪線....
建議買個細一點的滴管
補水後首次充電建議打開蓋子，因為初期會有氣體跑出
