3.7v 402530 300mAh Lithium Polymer Battery.

For a long time, I was looking for a battery that I could use in replacement to one Lead-acid, that has become worn in a led lamp. Fortunately, on Sellers page it was easy to find the final measures, in order to know if it would fit on available space. I was very sad to discard this lamp, so generating mor environmental waste. Now, I am happy because my lamp was upgraded to a more modern battery and as a plus, it weight much more less. In all the ways it was a very good choice. And it has arrived in less than a month, even considering Brazil Post re-dispatching fees and wasted time.
