Razr replacement battery source needed

[tjm999]

Anyone have a good source for a Razr XT912 battery? I can't find a good (cheap) source.
Thanks.

So the replacement batteries I'm finding are at least $60. The Maxx battery conversion is a good idea but at least $85. This is a well used phone. Has anyone tried those external clip on battery packs ($20)? A cheap option. If anyone wonders the phone is factory reset 4.0.4 and it dies in a few hours.
Thoughts??? Thanks.
