BP-K75L Replacement Parts

The battery is exactly what I wanted: it has tripled my time between charges and i love the orange color. Although these didn’t deter me from buying the battery a couple of improvements i think: the clasps that hold the battery to the radio are very difficult to push down and pull the battery off. I suppose that will ease with use but it still is quite difficult to pull off currently. The LED light is blue/red when charging. Not really blue. So some confusion a d getting used to in the beginning. Some items that would be nice to have: a clasp-on holder like the original battery has would be nice and/or a vinyl case for the entire radio for those of us who want to protect our investment a while longer. Finally a few more colors would be nice to choose from: that olive green, brought back, would be great as well as other ‘fun’ colors would enhance sales i think. Otherwise a fantastic battery tht I would buy again! Thank you for coming up with the idea and bringing it to market!
