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.

Highscreen Spider — 3.8V Li-ion Replacement Battery (TBT5957)
This is a 3.8V, 2200mAh Li-ion replacement battery for the Highscreen Spider smartphone. It replaces part number TBT5957 when the original cell can no longer hold a usable charge. Dimensions are 72.00 x 57.06 x 4.36mm — measure your existing cell before ordering if you are unsure.
- Highscreen Spider fit: The Spider uses a direct-connect flat cell with a three-pin flex connector carrying voltage, ground, and a thermistor line. The BMS on this replacement matches that pin layout and the charge voltage ceiling the Spider's PMIC expects at 4.35V.
- Bench tested on actual hardware: We cycled this cell through charge and discharge on the Spider platform. The BMS accepted the charge handshake without tripping the PMIC's overcurrent threshold, and the protection circuit cut correctly at the low-voltage floor.
- Fuel gauge recalibration on first use: On first use after installation, disable fast charging and run one full discharge-charge cycle at standard rate. This lets the fuel gauge IC map its coulomb counter against the new cell's discharge curve before any high-current charging pushes current into an uncalibrated state.
Why the Highscreen Spider reports wrong battery percentage after a cell swap
The Spider's fuel gauge IC stores a learned discharge curve from the original cell. When you fit a new cell, that stored curve no longer matches the actual voltage-to-capacity relationship of the replacement. The gauge reads voltage and maps it to a percentage using stale data, so the number on screen drifts. One full discharge to auto-off followed by a complete charge cycle rewrites the reference curve and brings the percentage display back in line.
Sudden shutdown at 20–30% on the replacement cell
This happens when the cell voltage drops sharply under modem or display load — a voltage cliff the fuel gauge did not predict. The Spider's PMIC shuts the device down to protect the cell before the displayed percentage reaches zero. It is not a faulty battery; it means the coulomb counter has not yet calibrated the new cell's internal resistance profile. Run two full discharge-charge cycles and the shutdowns typically stop. If they persist past three cycles, check that the flex connector is fully seated — a high-resistance contact causes the same voltage sag symptom.

Frequently Asked Questions
My Highscreen Spider won't turn on at all after the replacement battery sat in a drawer for a few months — is the cell dead?
Likely not dead, but the BMS has locked out due to voltage dropping below 2.5V per cell during storage. Connect the phone to a wall charger — not a PC port — and leave it for 20–30 minutes without attempting to power it on. The charge IC trickle-feeds current at a safe rate to bring the cell back above the BMS re-enable threshold, typically around 3.0V, after which the phone will boot normally.
Fast charging stopped working the first time I plugged in after fitting this battery — it only charges slowly now.
The USB-PD or proprietary fast-charge handshake the Spider negotiates depends partly on BMS parameters the charge IC reads from the new cell on the first cycle. Some replacement cells present an impedance profile that causes the charge IC to fall back to standard 5V charging as a precaution. Perform one full charge at the slow rate, then unplug and reconnect — on the second cycle the charge IC typically accepts the fast-charge negotiation once it has a baseline reading from the new cell.
The battery percentage on my Spider jumps around erratically — it was at 60%, then jumped to 35%, then back to 55% within minutes.
This is the fuel gauge IC recalibrating its coulomb counter against the new cell's discharge curve, which differs from the curve the original cell trained it on. The percentage display will stabilise after one or two complete discharge-charge cycles. Charge to 100%, use the phone until it shuts off on its own, then charge back to 100% without interruption — this gives the gauge IC a clean reference run and the erratic jumping should stop.
