  3. Battery Replaced

    New battery works wonderful. Battery keeps charge all day.

  4. DCS Guy

    I got the new battery to replace my existing headset battery. After it charged it makes the headset seem just like new.

  5. Dave

    The new battery works great

  6. Healthcare Extrodinaire!

    The battery replacement I ordered was delivered in a timely manner. It was more expensive than I had imagined it might be, but I had never ordered a replacement before then. I had a good, trouble-free experience ordering and receiving the merchandise.

  7. Steve

    Just what I needed, easy to install.

  8. Shilpa

    Everything went smooth. Service was very good. Product was delivered in a timely manner.

  9. Joe M

    The head set works great with the new battery, but it cost me $50.00 to get one to me, this is 1/2 the price of the head set.
    I think it would be better if they went with a cheaper battery.

  10. Shilpa

    Always user your website. Service is excellent!

  11. Patty

    We ordered a battery and received it several days before we thought we would, Awesome!

  12. Tracy

    Changing the battery, of course, was the common sense 1st option to see if the headset would work, hold a proper charge, etc. This battery did the trick!. Holding a charge all day – 8-9 hours of use and still going strong.

  13. tim

    My headset is going on 4 or 5 years old and still works fine. I like the headset, worth replacing the battery instead of buying new! Thanks,
