In this guide, I will show you how to do this.
Step 1: This is how we do it
What you will need: distilled water; small straight screwdriver; super glue or hot glue; syringe or pipette
Wear safety goggles and gloves, as the liquid in the battery is usually sulfuric acid
How to do it:
1/ Use a small straight screwdriver to remove the cover on the top of the Sealed 12v Battery.
2 / You will find few rubber or plastic covers on the individual cells of the battery, remove them.
3 / Use a pipette or syringe to fully charge the battery of the battery until the lead plate inside the battery is submerged, and you will be able to see the hole.
4/ In a ventilated place, close the lid and connect the charger for one hour. If you have filled all the cells, excess acid will come out. Put on gloves, absorb it with a little paper towel and dispose of it in a safe manner.
5 / Replace the lid, and then re-stick the lid on the lid with adhesive.
6 / Charge it well, it should have a better current capacity!
