Short of 1 day quarter hour

Review
Polar bear 1900MAH
~Rm53
~High quality Li-ion compared to common after market batteries

Pro's
-market value 1900mah is true (standby is way longer than stock SOT more or less same)
-proven better than stock on 1st charge (li-ion takes 1 week to reach potential)
-didn't explode on me

Con's
->50% drop power slower; <50% drop faster; <30% drop faster than ever
-didn't achieve results I wanted but heck the 150mah extra pushed extra few days.

Verdict
Lazy charge 2 battery, this is the way to go
There are cheaper options available, if u want to carry more reloads

Wanted to achieve 7 days, 3 hour+
