Hey Guys,
We have a W52 handset that's a little over 2 years old and the batteries are not staying charged as long as they used to. I'm sure we've just worn them out. Can we simply replace these with any AAA rechargeable batteries or are there some specific requirements?


Never mind, I decided to check the manual and found this:
Battery Information
Technology: Nickel Metal Hydride (NiMH)
Size: AAA
Voltage: 1.2V
Capacity: 800mAh
We strongly recommend you use the batteries complying with the above parameters.
Because the compliant ones can guarantee the specified operating time, full
functionality and long service life. The operating time of your handset depends on the
capacity and age of the batteries and the way they are used.
We recommend you use only the batteries that came with the handset or replacement
batteries approved by Yealink technology:
 Sanyo NiMH 800
 GP 850 mAh
 Yuasa Technologies AAA 800
Thanks for your share.
