Review: Works like a charm! - Gave life to my Rs. 500 worth mosquito bat, which I did not want to throw away as it is in a good condition. Just had to undo the screws on the bat to open it, then pull out the red & black cables from the old battery, connect the cables to the new battery, put the screws back on and you are good to go. I had to cut the plastic a little bit to fit the batter properly. The best part is that I got 2 batteries for less than 150 bucks, which is a good deal. It's now 4 days & I recharged the battery a couple of times and it is working as expected.
