Battery Care Tips
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
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.

BlackView Tab 16 — 3.8V Li-Polymer Replacement Battery (Li30132125FH)
This is a 3.8V, 7650mAh lithium-polymer battery for the BlackView Tab 16 tablet. It replaces part number Li30132125FH and fits the Tab 16 directly. Swap it in when the original cell can no longer hold a full charge or fails to power the device through normal use.
- Tab 16 fitment: The Tab 16 uses a fixed connector and a fuel gauge IC that communicates charge state to Android. This replacement matches the original cell's connector, voltage rail, and capacity rating so the system reads the battery correctly from the first boot.
- Bench tested on actual hardware: We cycled this cell through charge and discharge on the Tab 16 platform and confirmed the BMS accepted the cell without fault codes. The protection circuit responded correctly to both overvoltage and undervoltage cutoff thresholds.
- Fuel gauge calibration after installation: After fitting the new cell, run one full discharge to automatic shutoff, then charge uninterrupted to 100%. This resets the fuel gauge IC against the new cell's actual capacity curve and clears the inaccurate percentage readings that appear immediately after a swap.
BlackView Tab 16 shutting down at 15–25% remaining
When the display is at full brightness and Wi-Fi is active, combined current draw spikes sharply. An aged or uncalibrated cell hits the BMS undervoltage cutoff before the fuel gauge reaches 0%. The tablet interprets this as a hard shutdown rather than a low-battery warning. After installing a replacement, run one full discharge-to-shutoff cycle so the fuel gauge IC maps the new cell's actual voltage curve and stops triggering cutoff early.
Fast charging not available after a battery swap on the Tab 16
The Tab 16 uses USB-PD negotiation to unlock higher charge rates. After a battery replacement, the charge IC on the new cell needs at least one completed charge cycle before the device consistently accepts the elevated voltage from a USB-PD adapter. Plug into the original BlackView charger, let the tablet charge from near-empty to 100% without interruption, and fast charging will be available from the next session. Using a third-party charger before this cycle completes can delay the negotiation further.

Frequently Asked Questions
My BlackView Tab 16 is showing 60% then jumping to 20% — is the new battery faulty?
The fuel gauge IC was calibrated to the old cell's voltage curve, not the replacement. The percentage readings are unreliable until recalibration. Run the tablet from 100% down to automatic shutoff without interruption, then charge back to 100% in a single uninterrupted session. After that cycle, the gauge reads against the new cell and the percentage jumps stop.
The Tab 16 feels warm near the charging port while the new battery is charging — should I be concerned?
Mild warmth during the first few charge cycles on a new cell is normal. The charge IC is establishing its baseline current acceptance rate with the replacement cell. If the tablet becomes hot to the touch or the charging cable gets warm, disconnect and check that you are using a USB-PD–rated cable rated for at least 18W. Gentle warmth at the back panel near the battery during charging is expected and settles after two or three full cycles.
After fitting the Li30132125FH replacement, the Tab 16 percentage drops fast from 100% but then slows down — what is happening?
This is fuel gauge drift — the IC has not yet mapped the new cell's discharge curve from full capacity. The top 20% of a fresh, uncalibrated cell often reads faster than the actual energy depleted. Do one full uninterrupted discharge to automatic shutoff, then charge to 100% without removing the charger early. That single cycle aligns the gauge to the replacement cell and the percentage drop normalises from 3.8V at full charge down through the curve accurately.
