UPS with battery
The main cost involved in running a UPS are the batteries that have to be replaced every 2-3 years. Today, we will reveal you a simple trick that has been used by Geeks for decades to give a second life to batteries.
For this to work, all you need is a pack of Epsom salt and distilled water. Epsom salt is commonly available from any big chemist shop since epsom salt has many cosmetic uses as well. Some chemists call it Magnesium Sulphate so ask for both the names at the chemist.

Once you have these two things, follow the instructions below:
Take 2/3 cup of Epsom salt (MgSO4) and add it into 2 cups of distilled water.
Heat the solution on a stove in a sauce pan till Epsom salt is totally dissolved in the water.
Disconnect and safely remove battery from the UPS.
Wear safety equipment ( Gloves and safety glasses)
Open the filler caps of the battery.

Add an equal amount of the MgSO4/H2O solution into each filler hole of the battery till you have consumed all the solution.
Replace filler caps and put the battery on charging.
Thats it, now you need to wait for a week as the condition of the battery will start to improve by each passing day. The cells will de-sulphate and the battery will start to give better backup time by each passing day. The battery should give best performance in 8-10 days. You can use this trick after every passing year and use your UPS battery for an extra 2 years.
