Quote from ShadowP :

Folks are replacing thier Battle Borns with these higher capacity (and far cheaper) alternatives...and this particular unit is about half the cost of other similar brands, when those brands have their own issues.
edit: BTW, these may have the 'new' low temperature cells inside:
Discharging Temperature
-4~167℉/-20~75℃
Charging Temperature
19.4~149℉/-7~65℃
