What this battery fits

The PISKEKAT PO02XL is a 7.6V 37Wh lithium-ion replacement for many HP Stream 11 models including the 11-R, 11-Y, 11-AH and 11-AK series as well as Pro G2 through G5 variants. It matches part numbers such as P002XL, 823908-1C1, 824560-005, 824536-850, HSTNN-IB7G, HSTNN-DB7G and TPN-Q166. Owners of listed Stream 11 notebooks can use it as a direct swap.

Behaviour under sustained load

The cell chemistry delivers a steady 7.6 volts across the discharge curve so the laptop maintains consistent performance during long work sessions. Rated at 37 watt-hours, it supplies enough energy for extended browsing or document editing without the voltage sag that appears in worn-out packs. The battery is new and unused, so it starts at full rated capacity.

Thermals noise and power draw

Lithium-ion construction generates minimal heat during normal charging and discharging cycles. No moving parts means completely silent operation inside the chassis. Power draw follows the laptop's own management firmware, so the pack only takes the current the system requests. The 7.6V output matches the original specification, keeping thermal load identical to the factory battery.

Questions about this item

Does the 7.6 V 37 Wh Li-ion cell generate noticeable heat or fan noise during all-day use?

The battery itself has no moving parts and produces no audible noise; any warmth comes from the laptop's own charging circuit under load.

What must my HP Stream already have for this PO02XL to fit and connect?

It replaces the original 7.6 V 37 Wh pack (HP part numbers 823908-1C1, 824560-005, 824536-850, HSTNN-IB7G, HSTNN-DB7G, TPN-Q166) using the same internal connector.

Will this replacement work alongside the original 45 W AC adapter I kept from my older Stream 11-R014WM?

Yes, the 7.6 V 37 Wh chemistry matches the factory spec, so the existing 45 W charger will charge it normally.
