What this battery replaces
This 21Wh lithium-polymer pack replaces HP part numbers SF02XL, SHTNN-DB6H, TPN-C118, TPN-C119, 756417-001 and 756187-2B1. It fits HP laptop models that originally shipped with those batteries. Buyers who need a different voltage or capacity cannot use this unit.
Thermals and power in use
The cell chemistry runs at 7.4V and delivers 2860mAh of charge. Normal operation stays within the thermal limits designed for the original HP chassis. No active cooling or external power draw is required beyond the laptop's own charging circuit.
Build and daily handling
The black polymer housing matches the form factor of the listed HP part numbers. Connectors align with the motherboard header for direct installation without adapters. Users who need a higher-capacity pack or a different connector layout should look elsewhere.

Questions about this item
How do I install the SF02XL battery and what step do people often miss?
Power off the laptop, disconnect the AC adapter, remove the bottom case screws, unplug the old battery connector, fit the new 7.4 V 21 Wh pack, reconnect the cable, reassemble the case, then charge fully before first use.
What maintenance or replacement will the SF02XL need later?
The 2860 mAh lithium-polymer cell will gradually lose capacity; expect to replace the battery again once run time drops below your needs, typically after several hundred charge cycles.
What limit appears first under sustained use of the SF02XL?
The 21 Wh capacity sets the runtime ceiling; under continuous load the pack will deplete in proportion to the laptop's power draw, so heavy workloads drain it fastest.
