It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Oppo Reno 10 Pro / CPH2541 — 7.82V Li-Polymer Replacement Battery (BLP997)

This is a 7.82V, 2200mAh Li-Polymer replacement battery carrying OEM part number BLP997. It fits the Oppo CPH2541, CPH2525, Reno 10 Pro, and Reno 10 Pro 5G. Swap it when the original cell can no longer hold voltage under modem or display load.

  • CPH2541 / CPH2525 platform compatibility: Both handsets run the same 7.82V dual-cell Li-Polymer configuration with an identical BMS connector pinout and charge IC handshake — one BLP997 cell serves the full Reno 10 Pro line without modification.
  • Bench tested on actual hardware: We cycled this cell through charge, full discharge, and charge again on Reno 10 Pro hardware. The BMS accepted the charge IC handshake cleanly, thermal cutoff thresholds triggered correctly, and the coulomb counter began tracking from the first full cycle.
  • Fuel gauge recalibration on first use: Disable SUPERVOOC or any fast-charge mode for the first complete discharge-charge cycle after installation. This lets the fuel gauge IC map the new cell's discharge curve before high-current charging pushes current into an uncalibrated coulomb counter.

Sudden shutdown at 20–30% on a replacement BLP997 cell

A new cell has a different internal resistance profile than the degraded cell the fuel gauge IC was calibrated against. Under high-draw conditions — 5G modem switching, sustained display brightness — the cell voltage drops faster than the IC predicts, hitting the hardware cutoff threshold while the OS still reads 20–30%. The fix is one full uninterrupted discharge-to-shutdown followed by a full charge with fast charging off. After that cycle, the coulomb counter realigns to the actual voltage curve of the new cell.

SUPERVOOC fast charge not accepted after battery replacement

Oppo's SUPERVOOC protocol requires a BMS authentication handshake before the charge IC ramps current above standard 5V input. On the first cycle after a cell swap, the BMS may respond slowly or return an unrecognised flag, causing the charger to fall back to standard 5W charging. Plug in using the original Oppo SUPERVOOC adapter — not a third-party cable — and leave the phone stationary through the first full charge. Once the BMS completes its initialisation sequence, fast charging resumes at the correct voltage step, typically 10V.

Frequently Asked Questions

My Oppo Reno 10 Pro shuts off at around 25% battery after fitting the new BLP997 — is the cell faulty?

The cell is not faulty. The fuel gauge IC in the Reno 10 Pro was calibrated to the discharge curve of your old, degraded cell, so it misreads the voltage drop on the new one. Under heavy load — 5G radio, screen at full brightness — the new cell's voltage falls to the hardware cutoff threshold faster than the IC expects, triggering shutdown while the OS still shows 20–30%. Run one complete discharge to automatic shutdown, then charge fully to 100% with fast charging disabled — this resets the coulomb counter to the correct curve.

The phone has been sitting in storage for months and now won't power on at all, even on charge — what happened to the BLP997?

Li-Polymer cells left discharged below roughly 2.5V per cell trigger a BMS lockout to prevent reverse charge damage. After months in storage, the BLP997 has likely dropped below that threshold and the BMS is refusing to pass current. Connect the original Oppo charger and leave it plugged in for at least 30 minutes without touching the phone — the charge IC trickle-charges at a low pre-conditioning current to bring the cell back above 2.8V before the BMS allows normal charging to resume. If the screen stays dark past 45 minutes, try a second Oppo-certified cable, as a loose USB-C connection will stall pre-conditioning entirely.

Battery percentage is jumping around erratically — jumping from 60% to 45% in seconds — after fitting the replacement cell.

This is the fuel gauge IC recalibrating after the cell swap. The IC holds a charge map built from hundreds of cycles on the original cell — the new BLP997's impedance and discharge curve don't match that map, so percentage readings spike and drop as the IC tries to reconcile real voltage readings against stale data. Complete two full discharge-charge cycles with SUPERVOOC off and the phone not in use during discharge. By the end of the second cycle the coulomb counter has enough data points from the new cell to produce stable, accurate readings.
