GBBBT WH500 W745 Replacement Battery for Plantronics Savi Headsets

In this review of the GBBBT WH500 W745 Replacement Battery pack of 3, the bottom line is simple: this is a focused, affordable replacement for users who need reliable power for Plantronics Savi wireless headsets. The reviewer found these 3.7V 140mAh Li-Polymer cells to match the original battery form and output closely, making them a practical choice for workplaces or individuals who rely on Savi W440, W740 and related models and want a cost-effective way to restore headset runtime without replacing the entire base unit.

Key Features

• Exact Voltage and Capacity: The 3.7V 140mAh rating provides similar runtime to the original cells, helping restore normal headset usage between charges.
• Wide Compatibility: Labeled for Plantronics Savi models such as W440, W440-M, W740, W740-M, W445 and WH500, which avoids guesswork when replacing batteries for those headsets.
• OEM Part Number Matches: Cross-references Plantronics part numbers 204755-01, 82742-01, and 84598-01 so buyers can confirm fit with original documentation or their existing battery sticker.
• Safety Protection: Built with overcharge, over-discharge, over-voltage and short-circuit protections to reduce risk and prolong usable life compared with unprotected cells.
• Tested Quality Control: Each battery is tested to strict specifications, which helps ensure consistent performance across the three-pack for users who need multiple spares.

Who It's For

This replacement battery pack is best suited to office professionals, call center staff, or anyone using Plantronics Savi W440/W740 series headsets who needs to replace worn cells quickly and affordably. It is particularly useful for IT managers stocking spares or for individual users whose headset runtime has declined but whose base station and headset are otherwise fully functional.

Those who should look elsewhere include users with headset models not listed among the compatible devices, or buyers who prefer factory-branded batteries from the original headset manufacturer. Also, if you require higher capacity or different chemistry than the specified 140mAh Li-Polymer, consider other specialty battery options.

Pros & Cons

Pros
