Steps to Restore a Lawn Mower Battery

Note: Use of Personal Protective Equipment (PPEs):
Before starting work always wear Personal protective equipment like safety goggles, and safety gloves.
Removing of Battery:
The first step is to remove the battery from the lawn mower. While removing the battery note down the positive and negative polarities on the wire. If the indication for positive and negative is not right in the battery you might connect the battery in opposite polarity and it’s very dangerous. Note down the battery’s polarities before removing the battery.
Empty the battery:
The second step is to empty the battery from the old solution, clear all its plates and drain all the solution so that you start working on the restoration.
Cleaning of battery:
The third step is to clean the battery from the inside, for this purpose you may use baking soda with the distilled water. The baking soda will remove the sulfate and corrosion from battery plates. Mix the baking soda with distilled water and fill the battery with that solution. After two, or three hours clear the cleaning solution and drain all the solution from the battery. Also, rinse the battery with distilled water after clearing of solution (baking soda and distilled water)
Refilling of Battery:
Now refill the battery with the distilled water to the recommended level mentioned in the battery. If you have magnesium sulfate then you make a solution using magnesium sulfate with the distilled water.
Note: if you refill the battery with only distilled water there is no issue so don’t be confused about the magnesium sulfate
Charging of Battery:
Lastly, you can charge your battery as recommended by the manufacturer (Not more than 08 hours). After completion of charging you can wait for the cooling of battery plates. After cooling, install the battery into the mower and start using it.

Expiry of shelf life:
Another important reason behind the battery failure is the expiry of battery life. Normally, users never do maintenance of the battery and use it continuously for years so battery life expires. Always check the battery after two-three months.
Corrosion:
Corrosion is also an important reason behind battery failure. The corrosion accumulation near the terminals and the cell opening due to which battery is not fully charged. Slowey and gradually the battery stopped working. It is very important to clean the battery terminals and also unplug the terminals wire from the battery and clean it carefully.
Decrease in the level of Solution:
Sometimes the level of distilled water/ solution decreases in the battery and its stops working. So always check the distilled water/solution level frequently to avoid any hurdle during the work.
Natural Sulfate Buildup:
When the battery discharges, sulfates can stick to the plates inside. Over time, these sulfates can crystallize and build up, which limits the battery’s ability to undergo necessary chemical reactions. Regular reconditioning can help prevent this buildup.
