High-Energy-Density
Each Synergy Digital battery has the capacity to provide long-lasting, continual use. Boasting a high-energy density and high-power capability at a more constant rate, these batteries are made of Ni-MH to provide long-lasting, reliable power.
Long-Lasting Power
Using these powerful Synergy Digital Ultra Hi-Capacity Batteries, you can keep your Wireless Headset consistently powered for longer periods of time. A Ni-MH battery delivers substantially more current than any other battery in its class, boosting performance when servicing high-drain devices. In addition, each Synergy Digital battery is made with high-quality Japanese cells to ensure long-lasting use, so you never have to worry about draining off the battery the moment you really need it.
Long-Term Value with Less Waste
These Synergy Digital rechargeable ultra-high capacity batteries can be charged over and over thousands of times, so there is less waste. Simply charge your Wireless Headset and enjoy ultra-strong power for your device time and time again. Not only do you get more bang for your buck, but Ni-MH is also free of toxic heavy metals. As such, these batteries are recyclable and safer to use.
100% Compatible
Synergy Digital Batteries are 100% compatible with the original OEM battery. Its ultra-high-capacity provides longer-lasting use than the original OEM battery. Therefore, you can rest assured that your Wireless Headset will perform at its highest standard possible.

Purchased this in Dec. 2024. Completely useless, won't hold a charge by the end of February 2025.

Unboxed. Put into Sony headsets. Dead. Put on Sony headset charger, light on and after a few hours, light off. Turned on TV, no light at headset base nor sound from headset. Replace with old Sony battery. Worked perfectly. Summary, battery DOA and even after showing it was charged in full; still DOA. Yes both batteries were installed correctly.
