Apparently the battery is not replaceable.
I searched using https://www.google.com and the results suggest that unfortunately it is not meant to be replaced.

You must operate your bluetooth headset HBH-PV700 in discovery mode in order for your mobile to discover the headset and then pair the two devices. To activate the discovery mode of your headset, while it is switched OFF press the switch on button and leave it pressed for approximately 10 seconds, then search for it with your mobile and pair the devices. most of the times the code needed for pairing is 0000 (zeros)

Hi,
If this solution doesn't work hold down both the volume up and down buttons on the head set for about 5 seconds whilst searching for a new paired device with your phone then when asked enter the code 0000 and connect

hi thanks for using fixya!
Connecting a Bluetooth headset or hands-free speaker unit to your phone involves setting the headset to “discoverable” mode; check the headset manual for how this is done, as it varies by type and model. You’ll also need to find the headset PIN code in its manual – this is usually 0000 or 1234, but again it varies.
Go to Bluetooth menu – from the main menu highlight Settings (Figure 1), click Select, and scroll right to highlight the Connectivity tab. Highlight Bluetooth (Figure 2), click Select and then highlight Handsfree (Figure 3) and click Select.
When prompted to ‘Add a handsfree device’, choose Yes (Figure 4), and your phone will look for all discoverable hands-free units (Figire 5). Select the one that you want from the list that appears and enter the hands-free unit’s PIN code when prompted. The pairing will now be complete.
Once paired, you’ll find the headset listed under the My devices menu in the Bluetooth settings area, from where you can connect and disconnect it.
Hope it will help you. If you need further assistance, let me know!
Regards!
