@@Kgonothibasically he is trying to explain that if your battery is fully charged and showing 12.6v or 12.5v ( without any load ) then when you put load on your battery these values quickly drops from 12.6v to 12.3v or 12.2v and after that it remains stable at that. So this sudden drop doesn't mean that your battery was not charged properly. It's a natural phenomena for every Acid battery out there in the market.
I want to add one more thing. If we leave our inverter battery for 2-3 months without charging then it completely discharges. So if you have a solar panel you dont need to carry the battery to the shop for recharging. Just connect your battery with solar panel which gives more than 12v and charge with inverter. Solar panel helps to lift the charging so that it can be charged with inverter. As inverter requires minimum 12v power to function. I tried it. I found the new thing. Hope it helps you.
