  1. Work as intended

    Battery life last long, working with no issues

  2. Great Service

    Posted by Unknown on 27th Sep 2016

    Customer service was excellent, including follow up. Delivery was quick. Only have had the batteries for about a couple of weeks, and so far, it's proving to hold it charge and perform great. Only 4 stars just because I haven't had it long enough to test its longevity.

  3. Great service

    The original battery that came with my Plantronics headset was not working properly. I sent Merritt an email telling them it was not holding the charge. Within a few days another showed up at my doorstep and works perfectly and longer than the directions stated! Thanks Merritt--

    I've bought different models of this battery from other suppliers and they don't last nearly as long as these. Some of the cheaper ones died in a day or two.
