Happy Breffast!
Was it charged regularly in the remote area?
What was the battery voltage before you hooked it to the charger?
What was the battery voltage after being on charger for 48 hours?
Do all 6 cells have enough electrolyte to ensure the lead plates are fully submerged? If yes, do not add any additional distilled water.
Have you checked the specific gravity of the 6 cells with a hydrometer using a take-in, expel, take-in, expel, take-in, expel, take-in, record value method?

Have you added water yet?

Current flowing?
Be patient. Might take a week.
Is electrolyte covering the plates? If not, add distilled water. Not too much to avoid bubbling over while charging; plan to fill properly later.
If it does come up eventually, when done charging disconnect and let settle 12 hours, then check voltage. If low, needs higher equalization charge. Testing electrolyte specific gravity will also show.

No! I have not. Can I add DC water?
The manual is no longer available but my colleagues told me that I should use 20A automatic charger to charge it for 96hrs that it will come up. After 96hrs of charging, I should discharge the battery and charge it again.
Thank you. The electrolyte is covering the plate. My colleagues suggested same. The advice they gave me. My colleagues told me that I should use 20A automatic charger to charge it for 96hrs that it will come up. After 96hrs of charging, I should discharge the battery and charge it again.
No, it was not charged regularly, we disconnect the system. The battery volt was 10.5 volts before charging. After 48hrs of charging, it is 11.8 volts. The cell has electrolytes. Attached here on-screen is what the inverter is reading.

Okay, thank you. I am thinking of doing that but the gauge of the battery is still up. From 10.5 v to 11.8v after 48hrs of charging. See the reading from the inverter screen.

How do you use it? Where can I get the charged-it Battery Additive? Any picture of it? Or shop link. Thank you.
You add it to the electrolyte in the cells. Instructions come with it.

I use pulsetech chargers to recover batteries with very good results. The worse ones I had to actually swap out the battery acid on since it just resettled onto the plates after the charger freed the buildup from the plates. Was fun experiments back in the day but now I just replace the batteries if I see it floating around in the cells really bad from using the charger.

Battery additives are snake oil. Marketing claims are BS.
You can choose to use gimmicks, or you can choose to use the procedures recommended by the manufacturers who product batteries that typically last decades.
An equalization charge is far more beneficial; however, the battery must demonstrate the ability to achieve full charge voltage before equalization can be beneficial.
A FLA sitting for months completely depleted is going to be in bad shape, and may not be recoverable by any means. Even if it is recoverable, it will likely be significantly below rated capacity.
Check and record specific gravity of each cell.
Remove it from the system and leave the 10A charger on for another week.
Check and record specific gravity and voltage again.
Oh! Thanks for the Pulsetech chargers information. Do you know the specifications?
Thank you so much for the wonderful information. I appreciate. If 48hrs can increase the volts from 10.5 volts to 11.8 volts. That's mean, if I charge it for a week, it will definitely come up to 12.5 volts or more
Not all battery additives are snake oil. The magnesium sulfate or aluminum sulfate based additives work, just they don't work after the cell is too far gone.
