A great company I've bought batteries from everything from MT1000 to jedis, XTS is Hitech USA on ebay 35 bucks for 4000mah li-ion - "Hitech USA(Japan 4A TOP) For Motorola XTS" Their pictures are crap and not always correct, I knows its counterintuitive but the quaility of the product is excellent and has a 1 yr warranty If your stuck I'd give them a shot. the manufacturing is better than any chinese battery Ive bought. They use japanese cells and assembled in taiwan which may not mean much but I havent had problems
and honestly, anything more expensive than that I'd buy the real deal Impres and Ive bought used Impres batteries before but the seller showed it was good on an Impres battery data reader. I have one myself and if the seller has a return policy you can find out yourself on unsure batteries, if you have the data reader
