Reliance Lyf Flame 2 - Battery needed

I checked in the local mobile shops and online also.
But no battery for Flame 2 is available.

If anyone has bought replacement mobile for this model, pls send me the link.
Also one of my friend suggested intex has some of its models having similar configuration and design. So he is suggesting me to try that intex model battery in this phone. But he is not sure on the correct intex model no.

any suggestions welcome.

Note : My original Lyf 2 battery has been bulged both the sides. I can keep it till dec (Till preview offer)
New battery is to use the phone after december in home.

BATTERY MODEL : 455149ARE
