Review on TalentCell 9V Lithium Ion Battery: High Capacity 500MAh Rechargeable Li-Ion Polymer Battery With Micro USB Charging Port - 1-Pack For Ultimate Convenience by Craig Pears

This battery did NOT fit in my Shure wireless in ear monitor receiver pack. I have had this equipment for 4 years, and have never had an issue with (multiple brands of) batteries NOT FITTING INSIDE.In fact, it scraped a small serial sticker inside that I had to peel off just to fit the old battery inside. This battery caused damage.DO NOT RECOMMEND THIS BATTERY.I will be asking for a refund on this.Aside from the unnecessary and difficult packaging on the case AND the battery itself, they seemed to charge easily and quickly. Won't do much good if I can fit it in the gear.
