  1. as promised

    Received the battery in 2 days and had the headset up and running after being charged. Great service and very helpful you tube info!

  2. No more beeping due to low battery!

    Posted by CSR for Answering Service on 26th Aug 2016

    The battery is doing great. It has eliminated the beeping in my ear which was very annoying from the old battery being too low. Hope it lasts a long time.

  3. Fit perfectly, works perfectly

    I was sick to my stomach thinking about the possibility of having to buy a new headset. Found these guys online and watched the how-to video on replacing the battery in the CS361. $15 and two days later I had a like new headset. 10/10 would recommend working with Merritt.

  4. Don't Waste Money on New Headset

    Posted by David Cary on 29th Jul 2016

    So glad to find this company with helpful video demonstration on YouTube. I use my headset all day every day. But it has to work right. Battery finally gave out. Almost wasted $300 for new headset, but no need! Just get a replacement battery from Merritt. Easy to install if you're careful.

  8. Headset Battery Replacment

    Posted by Alan G on 1st Feb 2016

    I realized that my Plantronics headset was in need of a battery replacement. I went on the internet and was very fortunate to select your video telling me how to replace the battery and the subsequent link to order a new one. The process was extremely easy, the email notification and follow up was admirable and the price seemed very reasonable. My experience was an excellent one!

  9. Fit perfectly, lasts better than the original

    Posted by Kris Cook on 9th Apr 2015

    On 9/1/14 I ordered a replacement battery for my Plantronics CS50 headset. After calling when I didn't get it after a couple of weeks, and them tweaking their order fulfillment system, I received it promptly. I used the video to learn how to install it correctly, popped it in, and have been using it ever since. The headset lasts two full days on a charge. Even with the delay, I'd call this a perfect customer experience.

  10. The right battery

    Posted by Unknown on 8th Apr 2015

    I ordered an inexpensive battery off Amazon that wouldn't even begin to fit into my Plantronics CS361N headset. At that point I had to go through the hassle of a return. My next order was from Merritt. They have video on how to install the battery. It was a perfect clone of the original, and it worked perfectly.
