Query: Bluegrass Battery/ Battery Jack

This is a review of the web provider Bluegrass Battery listed on the Amazon site. I ordered two Tripp Lite RBC52 replacement batteries for my UPS (recommended by manufacturer). Bluegrass offered the best price. After more than two months, two wrong shipments and their return, and many emails, I finally have confirmation of a refund, less $13 for shipping and handling. The second battery shipment they insist was what I ordered according to their stock numbers could not fit upright in the battery compartment, was 2 Ah less in capacity, and required custom rewiring. This is what they insist is the correct replacement.
