But nowadays if 1 air conditioner is still turned on during the night, The battery will drain completely in approximately 9 hours when not charged by solar panel. (Around 7 PM to 4 AM)
Although the AC1 charger was still in-use which helps the battery not to drain faster and charge faster however it does not help if the air conditioner is turned on during the night.
This is because the battery is starting to show It’s age a little, I installed the batteries for my house in 2019 making it 4 years old as of right now, the 8 batteries that are installed are called “Duracell Ultra” the larger ones that have higher voltage, Duracell Ultra batteries typically last around 10 years before it completely stops working.
And one last thing, I also noticed that when I turn on the microwave to cook food, It puts a extreme amount of strain in our batteries and causes the AC1 charger to stop working and turn off temporarily making the battery drain even faster.
