The battery I got from DirectDeals4U is NOT a Plantronics OEM battery as described. However, the one I received is rated with a higher 240mAh rating than the original 190mAh and so far has lasted longer than the original one lasted even when it was new. I am 7 hours into a call as I type this and it's still going strong. There is no manufacturer name or ID printed on the battery (see customer image to see what I got) and time will tell if there will be issues, but so far, so good. Price was fair for a non-OEM part, though I have seen cheaper, but this one fits perfectly, delivery was very quick and shipped in minimalist packaging so very little waste to dispose of.
