Hi, all, Found a good deal on Amazon. 2 pack of 1600mAh battery with a charger just cost me $19.99 plus shipping (or free shipping if you are Prime member). It's a good quality battery. My wife was complaint about her EVO's battery life, she didn't like to bring power bank, then I got this battery for her. It lasts longer than the old original one. You can always have one fully charged spare ready to go while you have 2 pack with a charger. Check this out: use key word: Timetec EVO 4G battery, you will find it Hopefully it can ease your daily life a little!
