Replacement Battery

Theradome has designed its high-quality lithium ion battery to be used safely with its Theradome EVO LH40 and Theradome PRO LH80 models. Each battery has been designed so that each charge will yield between 10-15 treatments depending on the Theradome model. We’ve improved this battery so that it lasts for up to 1,000 Theradome treatments before a new battery is needed. This translates into up to five years of Theradome treatments. In addition, this battery includes a safety circuit that prevents over heating by shutting down the battery. Therefore, you can expect to always have a safe experience with Theradome products.

The Theradome.com site is the only place you will find the authorized lithium ion battery replacement for your LPT helmet. Using any other battery will void your warranty and Theradome cannot guarantee your helmet’s performance or safety. You will not find the Theradome battery on any other site, including Amazon or eBay. Only use trusted Theradome replacement products to ensure peak performance and safety.
