Your cart is empty.The Eartec Rechargeable 3.7V Lithium-Ion Battery is designed for use with the UltraLITE wireless headsets, and HUB systems. This lightweight battery is about the size of a match book, and is installed directly into the headset. Since the battery is Li-ion, it doesn't need to be drained, nor will it develop memory issues.

This set of batteries for our ultralite headsets are great. An earlier set (2) failed to take a charge and were returned, facilitated by Amazon. The replacements did, immediately. They are a second set, since the run time is about 6 hours, and we sometimes have longer cruising days. We love our headsets and can communicate constantly on a 40' trawler.

Knew I wouldn’t be disappointed ordering from the manufacturer. Haven’t tried third party batteries, but these work without any issues. Love it!

We got the eartec headset to talk to our parents COVID isolated in long term care. They are amazing for at use, volume and clearity far better than open window, cell phone, or even a patio visit. Left master headset with them, kids have remote and we drop off extra battery to swap out in parent's headset. Sanitizer and Safe.

Awesome, we use them to get the RV into tight spots. I read the reviews and take the batteries out between uses. And I also bought two extra batteries.

Shipping duration was fairly quick. As soon as I received these batteries, I put them in the charger (that came with the EarTec UltraLITE headsets purchased a few years ago. They charged up - and worked well in a brief test with e headsets. With the two batteries that came with the two headsets originally purchased, now I have four batteries...
