Will adding Epsom salt to the Dead Lead Acid battery make it work again?

 The Backup time of our Inverter battery (Lead Acid battery) got reduced to few minutes from initial 6-8 hours in 3 years.

From many forums, I came to know that adding Epsom salt (Magnesium Sulphate) to the battery cells will give back the initial Backup time. i-e We have to dissolve the 2 or 3 Spoons of Epsom Salt in a bottle of hot Distilled water, and we need to pour this solution into each of the battery cells. Actually adding water with Magnesium Sulphate gives the Sulfuric Acid which is required for replenishing the Lead Acid Battery.

i-e MgSO4 + H2O ->Mg(OH)2 + H2SO4

It seems we can try this option 3 or 4 times so that we can extend the battery life long time. And, according to these Forums, this approach will start giving the benefits only after doing 3 or 4 charging and discharging.

I am planning to try this in few days. I would like to know whether it will work out? And, whether there will be any risks involved in this process? And, where to get Epsom Salt? Few Forums say that Epsom salt will be available in Medical shops, Agriculture Stores and Grocery Stores. Is this Medical Epsom salt same as Battery Epsom salt?

I will update this blog once after I try this approach. You can visit this blog in few days to know the outcome.

WARNING: If you are going to try this approach, make sure that you use proper safety Tools to protect from the effects of Acid which may damage your eyes and skin.

Update: It didn't work for me. Did you try this? share your experience thro' the comments.
