LG is trying to win over some G3 sales by offering a free back-up battery pack for anyone in the U.S. who picks up the handset at a major carrier or retail outlet. Just have your IMEI and proof of purchase handy (so long as your purchase was not before today), then head over to www.LGG3promo.com to redeem.

The charger in question is a $70 3,000 mAh battery and charging cradle. The promo is running until September 22, so better get cracking. Anybody recently pick up an LG G3? Anyone still on the fence about snagging one?
