Most reliable product I bought a battery around 9 years back after a lot of thought process like all others and then trust me I am just topping up distilled water and guess what the battery is still working at its efficiency and now I bought the same battery to my current location as well and since 3 yrs it’s working really great and due to indoor placed and Bangalore weather the level of water is till maintained and it as anticipated the battery is lovely superb condition. A value for money product my research for reliable product is done and I wish to see other users experience too
