Replacement battery for EliteBook and ProBook G11
This 3 cell lithium ion battery replaces the original RX03XL pack in HP EliteBook 640 645 660 G11 and ProBook 440 445 460 465 G11 models. It delivers 11.58V and 56.04Wh capacity for mobile professionals who need a fresh power source. The unit is brand new and tested for correct voltage and circuit protection.
Thermals noise and power draw in normal use
The battery operates silently with no moving parts and produces negligible heat during typical office workloads. Its low self discharge characteristic helps retain charge when the laptop is asleep or powered off. CE FCC and RoHS certifications confirm compliance with safety and environmental standards.
Behaviour under sustained load
Under continuous drain the 4646mAh cell pack maintains stable current output without sudden voltage drops. The integrated protection circuitry guards against overcharge over discharge and short circuit conditions. Users who need longer runtime than 56Wh provides or who require a hot swappable second battery should consider alternative solutions.

Questions about this item
How do I install the 11.58V 56Wh 3-cell battery in my EliteBook 640 G11 and which step do people often miss?
Power off the laptop, disconnect the AC adapter, remove the base screws, unplug the old battery connector before lifting it out, connect the new RX03XL connector firmly, replace the cover and screws, then power on to let the system recognise the 4646mAh pack
What maintenance or replacement will the GreenTech RX03XL need over its service life?
The lithium-ion cells gradually lose capacity; expect to replace the pack once run-time drops below your needs, typically after several hundred full charge cycles, and keep the firmware updated so the battery gauge stays accurate
What limit appears first during sustained heavy use on this 11.58V 56.04Wh battery?
The 56.04Wh capacity sets the total energy available, so under continuous high load the charge depletes fastest, giving the shortest run-time before the laptop must be plugged in again
