e-Clouds 4 Volt 500 mAh 0.5 Ampere RB405 Mosquito Zapper Function VRLA Battery (Rated Capacity: 4V 0.5AH, Dimensions: ~ 58 x 36 x 20mm)

Good performance and long lasting, working perfectly.

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.

I purchased the 2 batteries, was skeptical at first as the catalog photos are different and the product I received was different brand when checked it wasn't charging or doesn't work. Would highly recommend to go to your nearest electronic parts seller and purchase from them if you're DIY. There is no return for the product so it's a Gamble

It works all right. Gives the right voltage. But drains off rapidly.I used it in mosquito squatter. After charging to full , it works well for 5-10 minutes but fails to give adequate high voltage output in the device. May be 500 mAh capacity is not enough to drive these devices.

Working perfectly

I had tried to replace the batteries in my chinese night lamp and also in the mosquito bat. I knew it was easier and cheaper to get replacement parts for the same, but still I went with it for testing. It was a bad decision.

I changed the batteries in my older mosquito rackets. After installing these ones both of the rackets started working.Really good product.

Even after charging for 8 hours it's nothing,no use
