About this replacement
HP Stream 7 5700 Series — 3.8V Li-Polymer Replacement Battery (PR-3258128)
This 3.8V, 3000mAh (11.4Wh) lithium-polymer battery replaces the original PR-3258128 / 795065-001 cell in the HP Stream 7 5700, 5700ng, and 5709 tablets. It fits the 7-inch tablet platform used for web browsing and media playback. Dimensions are 126.50 x 58.60 x 3.30mm — the same footprint as the OEM cell.
- Stream 7 5700 / 5700ng / 5709 fitment: All three variants share the same battery bay dimensions, connector pinout, and BMS handshake protocol. A single cell covers the entire 5700 sub-series without modification.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the Stream 7 platform. The BMS accepted the new cell without fault codes, and charge termination triggered correctly at full voltage.
- Fuel gauge recalibration after installation: After fitting this battery, run the tablet down to automatic shutoff, then charge uninterrupted to 100% before using it again. The Stream 7's fuel gauge IC calibrates against the old cell's profile — one full cycle resets it against the new cell and clears the inaccurate percentage readout that appears immediately after a swap.
HP Stream 7 shutting down between 15% and 25% remaining
The Stream 7 drives its display backlight and Wi-Fi radio simultaneously, and that combined load pulls voltage down sharply at the lower end of the charge curve. The battery management system reads that voltage dip as a near-empty cell and triggers an emergency cutoff before the percentage gauge catches up. This is more pronounced on an aged cell because internal resistance amplifies the sag. After fitting the new battery, completing a full calibration cycle — full discharge to shutoff, then full uninterrupted charge — brings the fuel gauge into alignment and pushes that cutoff threshold back to below 5%.
Fast charging not resuming after battery swap on the Stream 7
The Stream 7's charge controller uses a handshake with the charger on the first accepted cycle to confirm cell parameters before enabling higher charge rates. If you swap the battery and plug straight into a fast charger, the controller may default to standard rate until that handshake completes. Let the tablet complete one full charge cycle at whatever rate it accepts first. After that cycle finishes, unplug and reconnect — the controller re-negotiates and fast charge becomes available again.
