Replace a depleted notebook battery in an HP ProBook 6560B system with a 10.8 V, 84 Wh Battery Technology battery. This unit supplies the portable power source required when the original battery no longer holds sufficient charge for mobile work. Its stated application is the HP ProBook 6560B notebook platform, including the QR848US configuration. An 84 Wh rating identifies the battery's energy capacity, while the 10.8 V rating identifies the system voltage it is intended to support. Both values should match the electrical requirements of the installed notebook battery before replacement. The HP-EB8460PX9-6 is a battery component rather than an external charger, dock, or AC adapter, making it appropriate for restoring battery-powered operation in the notebook itself. Check the notebook model and the existing battery's voltage and capacity markings before installation. This battery is specifically associated with the ProBook 6560B family in the supplied compatibility information, so it is suited to maintenance of that platform rather than as a general-purpose laptop power accessory. Use it where a ProBook 6560B requires a replacement internal portable-power battery with the stated 10.8 V and 84 Wh electrical ratings.
